Abstract
The nuclear disaster in Fukushima which followed in the wake of the 3/11 Tohoku earthquake and tsunami has given rise to one of the most significant public health crises in modern world history, with profound implications for how nuclear energy is perceived. This paper analyzes the most dire phase of the Fukushima nuclear crisis, showing how the level of risk was assessed by nuclear experts and state-level actors who worked largely out of view of public scrutiny. In addition to examining how the accident progression in the reactors was addressed and conveyed to the general public, the paper addresses how the exclusionary zones were determined by Japanese and foreign governments in Japan. As the crisis unfolded and efforts to bring the reactors under control were initially proving ineffective, concerns increased that radiation dispersion was unmitigated, and with radiation monitoring by the U.S. military indicating levels significantly beyond TEPCO’s conservative assessments, the United States broke with Japan, recommending an 80km exclusionary zone, and initiating military assisted departures for embassy staff and Department of Defense dependents from Japan. These actions deviated significantly from Japan’s assessments (which had established a 30km evacuation zone), creating a dynamic where the U.S. provided technical consultation for the nuclear response while striving to maintain a delicate diplomatic balance as they attempted to impose a qualitatively different crisis management response. Because this crisis had significant implications for Japan's international relations, diplomatic considerations have helped to suppress the complex, often fractious relations between Japan and foreign governments - especially the United States - whose collective efforts eventually turned the tide from managing the nuclear meltdowns to ameliorating their long-term consequences. Based on interviews with political officials in both the Japanese government and foreign embassies in Japan, and nuclear experts and military officers who worked the crisis, the paper analyzes how technical assessments drove decision making and were translated into political policy.

Introduction
This paper analyzes institutional response to the Fukushima nuclear disaster, looking at how experts and key decision-making elites in the United States assessed the crisis and set policies as representatives of their organizations. In particular, it examines two related issues: the reactor meltdowns and the dispersion of radioactive fallout, and analyzes the political consequences of the divergent interpretations which developed in the first few days of the crisis around these issues. The framing of these central issues helped construct the general perception of risk that prevailed in this phase of the crisis, and provides a reference point against which to measure subsequent views as the crisis evolved over the longer term. The paper touches on the differences in perception between various foreign governments and examines the political implications of the crisis for international alliances in Japan.
In addition to examining how the accident progression in the reactors was addressed and conveyed to the general public, the paper will discuss how the exclusionary zones and evacuations from areas in close proximity to the Daiichi Nuclear Power Plant (NPP) were determined by Japanese and foreign governments in Japan. As the crisis unfolded and efforts to bring the reactors under control were initially proving ineffective, concerns increased that radiation dispersion was significantly beyond what TEPCO was indicating, and as a result, the United States recommended a 80km exclusionary zone and initiated military-assisted departures for embassy staff and Department of Defense dependents from Japan. These actions deviated significantly from Japan’s assessments (which had established a 30km evacuation zone), creating a dynamicin which the U.S.providedtechnical consultation for the nuclear response whilestriving tomaintain a delicate diplomatic balance as it attempted to impose a qualitatively different crisis management response.
This analysis is based primarily on in-depth interviews with diplomats in foreign embassies, military officials, journalists, nuclear scientists, and scholars, and examines how their collective narratives evolved in interaction with public sentiment as the crisis unfolded. The scope of the analysis is focused on the reflective perceptions of actors as they attempted to make sense of the crisis retrospectively after the 3.11 disasters. Because of diplomatic sensitivities and because some of the experts whose perspectives are represented in this analysis are constrained by organizational obligations that preclude them from revealing their identity, some of the sources remain confidential. In each case in which the identity of a source has been withheld, the information has been verified by independent sources.
"Meltdown" at Fukushima Daiichi
In the fitful hours after Japan experienced its largest ever recorded earthquake on March 11, 2011, the coastline of Tohoku lay in ruins from a tsunami that swept entire towns out to sea, resulting in the death of almost 20,000 people. As the world stood transfixed by the scale of devastation wrought by the tsunami, Japan ramped up its disaster management assets to address this crisis, coordinating its efforts with foreign governments and humanitarian relief organizations. While the international community initially mobilized to offer support for tsunami relief efforts in Tohoku, attention soon turned to the Daiichi nuclear power plant in Fukushima.
In retrospect, the condition of the Daiichi plant in the most dire phase of the crisis seems readily transparent, as an unending litany of bad news has cast the situation in such continuing negative connotations that, like Chernobyl, Fukushima has taken on talismanic connotations to serve as a symbol of nuclear dread. But in the first few days of the crisis, with little meaningful information being provided amidst the disorienting impact of the earthquake and tsunami, and TEPCO offering assurances that were uncritically passed on by the government and a docile press, hope remained that the situation could be brought under control. This wishful thinking was soon made irrational by the explosion of the outer containment structure of reactor #1, which was so powerful (the explosion broke windows 3km from the plant) that both plant workers inside the Daiichi complex and nuclear experts watching from afar initially believed that the reactor core itself had exploded.
With the explosion of the reactor #1 building there was no doubting the significance of this crisis, but calibrating the actual risk and danger that this presented to the general public was a moving target, with competing risk narratives that developed almost immediately after the initial news reports were released that the Daiichi and Daini nuclear power plants in Tohoku were in trouble. In the first few days of the nuclear crisis the information made available to the public was confusing, contradictory and frustrating. Despite a massive explosion that destroyed the outer, secondary containment structure of the Daiichi reactor #1 building, soon to be followed on the next day by a similar explosion of the reactor #3 building, TEPCO insisted that the primary reactor core containment was intact and that there were no releases of radiation that posed a threat to public health. Initially, conjecture held sway, with the foreign media challenging the Japanese press corps, who did little more than pass along TEPCO's announcements, essentially serving as a PR agency for the utility.
By this time, the Japanese and foreign media reportage characterized the situation as dire, even as the TEPCO officials and government were staging press conferences that offered platitudes of assurance while conveying facts that contradicted these statements. For the reporters who covered the crisis, the information provided by the utility was incoherent, contradictory and alarming. At the Wall Street Journal (WSJ) offices in Tokyo, senior editors debated how to characterize the crisis. When the government spokesman Edano Yukio conceded on March 13th that one of the reactors might be in “meltdown,” the WSJ editors noted that the nomenclature of “meltdown” as a label to describe the situation was culturally distinct, with different nuances of meaning between the Japanese term “炉戸溶融 (ろしんようゆう)” and the Western notion of a “meltdown,” which carried more ominous connotations than the straightforward transliteration of the word “meltdown” into Japanese.1
The Merriam-Webster dictionary defines the term “meltdown” as including “[1] the accidental melting of the core of a nuclear reactor; [2] a rapid or disastrous decline or collapse; [3] a breakdown of self control, (Merriam-Webster Dictionary, 2012), and the Oxford English Dictionary explains that “a meltdown was originally a catastrophic accident in a nuclear reactor, but this literal meaning has been swamped by the figurative sense of ‘a disastrous collapse or breakdown’. The term is now used metaphorically to refer to a chaotic loss of control, which is derived from the accidents at Chernobyl and Three Mile Island, where the reactors “ran away” from operator control, releasing significant amounts of radiation as a result of their errors. These accidents are now widely regarded as being the result of institutional failure, and TEPCO’s parsing of the term may have been a way to skirt the issue of responsibility by placing the emphasis only on the melting of nuclear fuel, rather than their own loss of control of the plant.
Although the term “meltdown” is in common usage, and was invoked by the press almost immediately after the crisis began, within the scientific community this term is not recognized as a scientifically meaningful description. The term is not included in the International Atomic Energy Association’s 224 page “Safety Glossary” which enumerates terminology used in nuclear safety and radiation protection, and the term “partial core melt” is used only once to describe a Level 4 “Accident With Significant Off-site Risk,” as indicated by the International Nuclear Event Scale (INES), which charts the levels of magnitude of nuclear “events”. The scale is an indication of the inherent industry bias of technical description, denuded of adjectives or critical phraseology that might be construed as danger. The International Atomic Energy Association (IAEA) refers to this as “a simple scale, designed for promptly communicating to the public in consistent terms the safety significance of events at nuclear facilities" (my emphasis).
On May 24, 2011 on the eve of a visit by an IAEA delegation, TEPCO officials announced that their data indicated that three of the reactors had in fact experienced meltdowns within hours of the loss of power following the tsunami. At this press conference, the issue of how this was previously characterized was revisited, with TEPCO now claiming that the meltdowns could only then be confirmed, and that they had previously suggested this possibility in reactor #1 on May 14, 2011. The media coverage of this revelation challenged TEPCO’s motives for revealing this information months after the fact, suggesting that this was in deference to international pressure, as a face-saving gesture directed toward the visiting delegation of IAEA ministers. Alternate media and independent reporters had been asserting the possibility of multiple meltdowns from the beginning, and while this possibility was presented by mainstream press as well, these stories were tempered by the acknowledgement that with no ability to see within the reactors, these scenarios were speculative at best.
For nuclear experts, the debate over whether or not meltdowns had occurred was largely a political controversy being played out in the echo chamber of the mass media, as it was taken as a given that significant meltdowns had started early in the trajectory of the reactor accident progression (TEPCO would late specify that within 8 hours after the loss of power, meltdowns had occurred). In the scientific community it has long been recognized that at high temperature the zirconium alloy cladding that holds the fuel rods melts, drawing off oxygen from the surrounding water and liberating hydrogen, a highly volatile gas. Despite the venting of radioactive gases in the Three Mile Island (TMI) accident, the most ominous threat that the accident posed was a hydrogen explosion that could have blown the reactor out, leading to a catastrophic release that would have been much more severe than what actually transpired. Through intense scrutiny it was determined that the infamous hydrogen bubble that built up inside the reactor #2 building at TMI could not explode due to a lack of oxygen, and remedial efforts were able to reduce the size of the bubble until it was no longer a threat. But in Fukushima, the powerful explosions that destroyed the buildings housing the Daiichi reactors could only have happened if a core melt was significant enough to release high levels of hydrogen gas, and the subsequent explosions were proof positive that catastrophic meltdowns had already occurred. As a result, while the media debated the relative chances of a meltdown and quibbled over the nomenclature, the nuclear experts who worked the crisis knew early on unambiguously that the Daiichi plant was in deep trouble, and mobilized their resources accordingly.
As the Daiichi plant’s condition rapidly deteriorated, it became clearly evident that the situation was beyond the control of the TEPCO administrators, which undermined their authority, lending credence to the widespread perception that they were not forthcoming with information. Government officials and TEPCO spokesmen claimed that they had been withholding this information in order to prevent panic in the early days of the crisis, but this revelation was taken as evidence that officials were deceiving the public and that TEPCO was more concerned about protecting its investments than it was in ensuring public safety.
For the foreign press, the devastation of the tsunami was the initial focus of coverage, diverting attention from the nuclear crisis, which in the first few days remained opaque, while the implications of the tsunami were clearly evident. Although major media conglomerates such as Reuters, The Wall Street Journal and the Associated Press had the resources to divide coverage between the two conjoined disasters, other major media organizations such as the New York Times, The Times of London, the BBC and CNN have scarce resources on the ground in Japan (most of the Asia bureaus for major media outlets have moved from Japan to China in the last decade), and the senior editors for these publications were mobilized to the coastland of Tohoku to cover the tsunami.
The media followed a pattern that played out in the foreign embassies in Japan as well, in which nuclear experts in their home countries provided consultation for assessing the situation. But while these authorities may have had considerable experience dealing with nuclear issues, they had virtually no culturally contextualized knowledge of Japan, and in the short-term had no access to more nuanced local information of what was transpiring at the Daiichi plant. Organizational elites, both in the diplomatic corps and in the foreign media, relied primarily on the Japanese mainstream media for more specific information, tempering this with the widely divergent, often random reports that were filtering out through social media, which, being less constrained by organizational vetting and mainstream considerations, tended to be more alarmist, amplifying the analysis to interpretations that often were dismissed because they were at the time unwarranted by the facts (which, after all, were not available at that time). In retrospect, many of these reports have been vindicated by information that has gradually become available as a series of revelations by disgruntled former industry officials, retired government authorities and scholars has given credence to views that had previously been seen as overwrought.
Radiation Plume Politics
At Three Mile Island, it was not until three years after the accident that plant managers were able to look into the reactors and determine that the core of reactor #2 had melted down. At Fukushima, with a station blackout and the plant in disarray as staff frantically tried to recover power, the situation in the first days of the crisis remained fluid, with little meaningful information to convey. If the actual situation was unclear to workers inside the plant, it was entirely opaque to those outside, including the diplomatic corps at embassies in Japan and nuclear authorities from abroad, who were pressing the Japanese government to provide specific information. In addition to concerns about what was developing inside the reactors, a central issue of risk assessment – and trust - was related to the spread of radiation disseminating from the plant. After a frustrating delay in venting reactor #1 that pitted Prime Minister Kan Naoto against a recalcitrant TEPCO management that was internally divided and uncooperative, evacuations from nearby the plant commenced with little government guidance and no information made available that could help guide prefectural authorities in their actions.
The Japanese government had established a computer modeling “System for Prediction of Environment Emergency Dose Information (SPEEDI)” in 1980, following the Three Mile Island nuclear accident, and the system remained functional throughout the nuclear crisis. SPEEDI was designed to provide detailed computer modeling projections of how weather patterns dispersed radioactive fallout into the environment.
As fears about the reactors heightened and TEPCO prepared to vent reactor #1, on March 12 the government evacuated four towns located nearby the reactors, increasing the evacuation zone from 2km, as decided in the evening of the previous day, to 10km (6.2 miles, cf. Table 2). Two of the towns – Futaba and Okuma – were assisted in the evacuation, with the government providing buses to transport citizens. Despite this initial support, refugees from Namie and Tomoika, who were in evacuation areas initially only 8km (4.4 miles) from the plant, were thereafter left to fend for themselves with neither direction nor support offered by the Japanese government, and fled northwest, right into the path of the radioactive plume, just where SPEEDI, had it been implemented, would have predicted the fallout would go. This scandal firmly linked the Japanese government to TEPCO as corrupt and incompetent on fundamental issues of radiation assessment. Whereas the hapless handling of the reactors had been attributed to a lack of regulatory oversight that prefigured TEPCO's chaotic response to the disaster, the SPEEDI scandal was seen as being the result of incompetence at the highest levels of government, betraying a lack of concern for the people most at risk from the nuclear disaster.
Despite having elaborate evacuation plans that previously had been coordinated with TEPCO, Baba Tomatsu, the mayor of Namie, initially learned of the nuclear disaster by watching it on TV and was bitterly resentful of the lack of consideration that put his village at risk:
There was no coordination with the Japanese Government. Nothing. They didn’t tell us where to evacuate. Nothing. Namie machi did everything by ourselves. And, disappointingly, because we didn’t hear anything from the government – no advisories – we used anything that we had—school buses and such—to move people out of the area. People’s cars were destroyed by the tsunami so we placed those people in those buses. At that time, the people who had ways to evacuate had already evacuated, to Miyagi, or Yamagata prefecture. So the 21,000 population were all scattered like a bee’s hive.2
Because we had no information we were unwittingly evacuating to an area where the radiation level was high so I'm very worried about the people's health. I feel pain in my heart but also rage over the poor actions of the government… It's not nice language but I still think it was an act of murder. What were they thinking when it came to the people's dignity and lives? I doubt that they even thought about our existence.3
The New York Times helped break this story in the foreign media in a critical analysis of how officials withheld information and the subsequent influence this had on Japanese public opinion toward the government. Onishi Nori, one of the reporters who worked the story, emphasized the qualitative shift in orientation that this brought to Japanese politics:
In the first couple of months after 3.11, the public inclination was to still trust what the government was saying and what the media was describing, but that started to breakdown by May, and that was reflected in public opinion polls at that time.
The recognition of the meltdown was big. When the Japanese government finally acknowledged that there was a meltdown in mid-May, the Japanese people said, “what does this mean?” The foreign media had written about the meltdown in the first week of the disaster, and the Japanese government had criticized the foreign media for being alarmist, and here they were a few months later saying 'oh yeah, I guess there were meltdowns.'
That was a key moment, as was the SPEEDI issue. That breakdown in trust toward the government, toward the media – you never really saw that before last year. For the first time, I had many people say to me 'thank God for the foreign media, they are the only ones telling the truth'.4
Elements of this story had already been covered in the Japanese media, dating to April, 2011, when Kosako Toshiso, a former professor at the University of Tokyo and member of the government’s impromptu advisory group on radiation, resigned in protest over the government’s mishandling of SPEEDI, linking it to subsequent arbitrary loosening of radiation danger threshold standards. Kosako’s resignation was the first significant crack in the public façade being maintained by the government, and this story increased in significance as it was associated with government deception and collusion. By April, an Asahi Shimbun public opinion poll indicated that only 21% supported the Kan administration with 60% opposed, and in response to the question “Do you think the government’s dissemination of information about the accident in the Fukushima Daiichi nuclear power plant was appropriate?” only 16% answered in the affirmative, with 73% saying that it was inappropriate.
With the SPEEDI data, it appears that social media was instrumental in making the system known outside a small circle of bureaucrats who were reluctant to act on the information, and who themselves were not initially aware of the database because this information was compartmentalized in other offices and no one was discussing it. With no one asking the right questions to the right people, the information lay dormant. The SPEEDI data was not initially conveyed to local officials in Fukushima, but was known to some Japanese government officials in the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the government office under which SPEEDI is administered. Although the staff who were compiling the information for the SPEEDI computer modeling had data in-hand by the first day of the accident, they withheld the predictions, claiming a lack of certainty about its accuracy due to incomplete data (the model depended in part on data from the nuclear plant, but with the power supply down, this was not available to factor into the overall assessment).
Suzuki Kan, the Vice Minister of MEXT, the agency in charge of radiation assessment, did not know about SPEEDI and learned of it only when Hayano Ryugo, a particle physicist and Chairman of the Department of Physics at the University of Tokyo, approached him to inquire how the SPEEDI data was being utilized and to request access to the data so that he could run an analysis. Minister Suzuki thereafter made internal inquiries and confirmed on March 19th that the system was operative but not being properly utilized, but in the interim, Professor Hayano began Tweeting about SPEEDI, drawing attention to the issue.5
Yahoo Japan had recommended Hayano on their top-page as a person of note shortly after the nuclear crisis began, and thereafter, his following grew exponentially to reach a broader public audience. These Twitter posts also came to the attention of Shikata Noriyuki, who at the time of the nuclear accident was Deputy Cabinet Secretary for Public Affairs and Director of Global Communications at the Prime Minister’s Office. Secretary Shikata informed Deputy Chief Cabinet Secretary Fukuyama Tetsuro on March 15 and information about SPEEDI was then conveyed to the U.S. Embassy and military through the Ministry of Foreign Affairs. SPEEDI was not revealed officially to the general public until March 23, but by then, information about this system was spreading through social networks and into the mainstream media.
This information flow became an important feedback loop, providing information to MEXT officials about their own system. Shikata, who after being approached had started following Hayano’s tweets, and began consulting with him about technical matters to assess the accuracy of the scientific data they were attempting to convey at governmental press conferences. Shikata then asked Hayano to help him inform the foreign media because of his bilingual language proficiency and his ability to communicate about technical issues clearly and efficiently.6
It is by now a common belief that the confusion that reigned in the immediate aftermath of the tsunami and nuclear crisis was due to a lack of information. While this may have been the case for the general public who lacked access to meaningful information and were relying on media reports, TEPCO and the Japanese government had multiple sources of information that could have helped contextualize and explain the efforts they were taking to address the situation. Rather, TEPCO was initially reluctant to acknowledge the seriousness of the crisis and instead of explaining the situation, simply provided raw data without an interpretative frame that would have allowed non-specialists to make sense of the information and assess their claims. William Sposato, the Deputy Bureau Chief of the Wall Street Journal in Tokyo characterized the reaction of many of the foreign journalists who were working the crisis at this time:
I don’t know of an instance where they lied deliberately, but their news conferences went on forever, they were filled with useless information, and they were unwilling to distill that information. They knew more about this than anyone else, and they could have taken the body of information they had and said ‘this is what we think is the most significant information that you need to know – this is the line we think you should look at’”. Unbelievable amounts of data, and the data would keep shifting: ‘today we have becquerels per square meter 100 yards from the plant. Tomorrow, we have millisieverts per hour a mile away from the plant.’ Is it getting better or is it getting worse? Their data gathering was just all over the map.7
Ironically, while TEPCO was “drowning journalists with data” (as Christoph Neidhart, the German daily Sueddeutsche Zeitung Tokyo bureau chief who attended their daily press conferences put it),8 Hayano’s Twitter posts reached a large and diverse audience, and was all the more persuasive because of its brevity. Where it not for Hayano, cogently encapsulating complex technical information into 100 character tweets and talking with the appropriate officials, the information may not have come out.
The SPEEDI contretemps, as with the divergent interpretations about the condition of the reactors previously discussed, indicates the complexity of how information develops and is utilized in complex, “normal accidents”. The multiple government and embassy offices, rather than being integrated under a common chain of command as part of an integrated crisis management system, compartmentalized information in silos, not only ineffectively communicating outside their respective bureaucracies, but often not discussing important facts even among themselves. The press helped link these together, as it pushed and prodded for information, compelling officials to explain their actions and account for their policies.
While the Japanese press attempted to burrow down into the details of the organizational chaos, the foreign press continued to amplify the crisis, framing it in terms that would appeal to foreign viewers who were distracted from the tsunami because of the crisis and disinterested in the internecine politics of obscure bureaucratic officials. Taken together, these combined into a compelling narrative arch, as the Japan-based journalists revealed bureaucratic ineptitude that provided a grounding in reality to the more critical views that were gaining traction. Lacking contextual perspective, and with scarce information available in any case, the foreign press played up fears of apocalyptic doom. Lacking information about what was really transpiring at the Daiichi plant and living through the uncertainty and chaos in those early days after the earthquake, the local press looked for explanation in the actions of specific organizational elites, and found little of worth. These views aligned in the assessment of foreign authorities, who, doubting the information they were receiving, began to distrust the leaders who were providing it.
The controversy over the SPEEDI data was later compounded by the disclosure that on March 14 this data, which had been withheld from local Japanese officials and those in the path of the fallout (the Japanese public did not find out until 9 days later), had been released in hourly reports to the U.S. embassy and military who were working on relief efforts in the area. For many, this hardened views that TEPCO and the Japanese government were more concerned about vested interests and state-level political concerns than they were about the well-being of their most vulnerable citizens. It also raised questions about what was really transpiring behind the scenes while these entities ineptly attempted to manage the story and project an increasingly implausible facade of control.
Negotiating Risk: International Divergence in Radiation Assessment
In the immediate aftermath of the tsunami, an unprecedented relief effort comprised of domestic and international NGOs, unaffiliated citizen volunteers, and government associated organizations from 116 countries descended on Japan to provide disaster relief in the Tohoku region. This impressively international outpouring of support demonstrated genuine humanitarian concern, and it cast the most unambiguously positive light on the 3.11 crises. While initially these tsunami relief efforts stood as a salutary example of international cooperation, as the nuclear crisis unfolded and eclipsed attention on the aftermath of the tsunami, this narrative turned toward one of confusion, suspicion and deceit, with TEPCO - and, by association, the Japanese government - being cast in a negative light, not only by Japanese citizens, who were increasingly feeling misled by government authorities, but by foreign governments, who were frustrated by the lack of information being provided by TEPCO and Japanese government officials about what was actually transpiring at Fukushima Daiichi.
Because of its long-standing strategic political alliance with Japan, buttressed by the largest array of military bases outside the continental U.S. and the only forward-deployed nuclear aircraft carrier group in the U.S. military, the United States was the most significant foreign responder in tsunami relief efforts and provided the most meaningful consultation and logistical support in the nuclear crisis. The U.S. Pacific Command (PACOM), working in coordination with USAID and other federal agencies, was intimately involved in relief efforts in Tohoku from the beginning, and working closely with the Japan Self-Defense Forces (SDF), were significant first-responders to coastal villages that had been swamped by the tsunami. These joint operations in total involved 140 U.S. aircraft, 19,703 personnel and over 20 American naval ships, which represented a significant portion of the U.S. 7th fleet Naval Forces. U.S. troops participating in Operation Tomodachi (Friendship) worked in close coordination with the Japanese Ministry of Defense and SDF, a rare moment in the often fractious relations the U.S. military has experienced in Japan. Japanese public sentiment toward the U.S. soared as a result, with 84% of Japanese polled in the Cabinet Office’s annual report saying they had friendly feelings toward the United States, the highest tally by far since the survey began in 1978. These findings were replicated in a poll commissioned on June 9 by Japan’s Foreign Ministry (84% approval), and in a Pew Global Attitudes poll (85% approval) taken on June 1, 2011 which found similar results.
The U.S. government and military support for tsunami relief efforts through Operation Tomodachi have garnered considerable attention, but less is known about the role the U.S. military played in helping to respond to the Fukushima nuclear crisis. With the Sendai airport rendered inoperable by the tsunami, the U.S. Navy's Ronald Reagan aircraft carrier group, parked off the coast of Fukushima, served as a fueling platform and staging area for tsunami relief, at which time military personnel were exposed to radiation emanating from the reactors. As the wind was blowing out to sea for the first couple of days after the onset of the crisis, aside from local communities near the Daiichi facility, servicemen on this nuclear powered aircraft carrier were among the first to be exposed to the radiation plume from the explosion of the Reactor 1 building on March 12. The exposure levels both on the ship and on the shoes of US servicemen who had temporarily landed on a Japanese command ship at 50 nautical miles from the plant were unexpectedly high, provoking the carrier group to back off from 60 to 180 nautical miles from the plant.
In transcribed telephone conversations between U.S. based federal government officials, nuclear authorities, U.S. embassy officials in Tokyo and military staff in the Pacific Command (PACOM) made available through the Freedom of Information Act (FOIA), the U.S. government response to the nuclear crisis can be seen in real-time as it played out over the course of the first month of the crisis:
ADMIRAL DONALD: (...) Earlier this evening, as the USS Ronald Reagan was operating off the coast of Japan, we - the ship just arrived. We had given the ship some guidance as far as positioning was concerned to stay clear of the area of the potential plume, basically told her to stay 50 miles outside of the radius of the -- 100 miles -- excuse me -- 50 miles radius outside of the plant and then 100 miles along the plume with a vector of 45 degrees. The ship was adhering to that requirement and detected some activity about two and a half times above normal airborne activity using on-board sensors on the aircraft carriers. So that indicated that they had found the plume and it was probably more significant than what we had originally thought. The second thing that has happened is we have had some helicopters conducting operations from the aircraft carrier and one of the helicopters came back from having stopped on board the Japanese command ship in the area, and people who had been on -- were on the helicopter who had walked on the deck of the ship, were monitored and had elevated counts on their feet, 2500 counts per minute. But I wanted to get you guys on the line and my expert on the line so we can get the data and then the proper people notified.
MR. PONEMAN: Okay, I have a couple of questions. Number one, in terms of the level of radiation that you are picking up, what's the delta between that and any information we have from the Japanese or other sources of what the level of radiation would be, given the venting and so forth that we know has occurred?
MR. MUELLER: So -- this is Mueller -- the sample that was taken and then what we detected, we were 100 nautical miles away and it's -- in our terms it's -- compared to just normal background it's about 30 times what you would detect just on a normal air sample out at sea. And so we thought -- we thought based on what we had heard on the reactors that we wouldn't detect that level even at 25 miles. So it's much greater than what we had thought. We didn't think we would detect anything at 100 miles.
MR.. PONEMAN: You didn't think you'd detect anything at 100 miles. Okay, and then in terms of the regulations and so forth of people operating in these kinds of areas, I forget some you know, acronym for it, PAG (Protective Action Guidelines) or something, how do the levels detected compare with what is permissible?
MR. MUELLER: If it were a member of the general public, it would take -- well, it would take about 10 hours to reach a limit, a PAG limit.
MUELLER: Right. For a member of the public.
PONEMAN: Right. You mean, at the level you detected?
MR. MUELLER: Yes sir. But 10 hours, it's a thyroid dose issue.
MR. PONEMAN: Okay, but the net of all this is that the amount of release that is detected by these two episodes whatever you would call them, is significantly higher than anything you would have expected what you have been reading from all sources?
MR. MUELLER: Yes sir. The number specific number we detected was 2.5 the times 10 to the 88 minus nine microcuries per milliliter, airborne, and that's particulate airborne. It is -- we did not take radioiodide samples so I don't know that value, but this is particulate airborne...
MR. PONEMAN: Tell me again exactly how you picked up these two forms of samples.
MR. MUELLER: We have automatic detectors in the plant that picked up -- picked up the airborne, and all of our continuous monitors alarmed at the same level, at this value. And then we took portable air samples on the flight desk and got the same value.
ADMIRAL DONALD: These are normally running continuous detectors, continuous monitors that run in the engine room all the time, monitoring our equipment.
MR. PONEMAN: These are detectors on the Reagan?
ADMIRAL DONALD: On the Ronald Reagan, correct.
MR. MUELLER: Yes sir.
MR. PONEMAN: On the Ronald Reagan. They are there because you have got equipment there that you know, it could emit stuff and while you were there, you picked up stuff that was ambient which indicated that you actually were in the plume?
MR. MUELLER: That's correct.
MR. PONEMAN: And this was -- this was 30 times higher than what you would have expected?
MR. MUELLER: Yes sir.9
With the Daiichi plant still a black box, and only spotty data to indicate the radiation dispersion, the U.S. quickly set up an independent parallel process of acquiring data, utilizing their vast array of military and governmental resources. These included the Department of Energy’s Atmospheric Monitoring System (AMS), on the ground radiation measurement surveys, fixed station radiation monitors, the RQ-4 Global Hawk military drone and classified military surveillance (the Lockheed U-2 high-altitude reconnaissance aircraft and the P-3 Orion maritime surveillance aircraft) and the nuclear aircraft carriers to help with the assessment. In order to make sense of this data, the U.S. relied on Nuclear Regulatory Commission (NRC) administrators, who coordinated with the Department of Energy and the National Atmospheric Release Advisory Center at the Lawrence Livermore National Laboratory in California, analysis by Naval Reactors' experts at their research labs (comprised of approximately 6,000 staff), and an ad hoc collection of loosely affiliated former government specialists, retired military officers (nuclear engineers), scholars and former NRC staff. In order to consolidate these resources into an integrated command structure, the U.S. embassy in Tokyo conceived a “Bilateral Assistance Coordination Cell” (BACC), which met daily and included all USG agencies.
Through diplomatic channels, with U.S. Ambassador Roos representing the State Department, the U.S. attempted to coordinate its response with the Japanese government. This had started soon after the onset of the crisis, focusing on tsunami relief efforts as the Japanese Self Defense Forces (SDF) and the United States Forces Japan (USFJ) developed joint operations using both U.S. and Japanese military bases as staging grounds for mounting their operations. With a keen eye on the diplomatic implications of the crisis, state-level actors took pains to highlight mutual cooperation, despite frustrations that developed backstage as the power outage at the Daiichi plant developed into a full-blown crisis. Until the U.S. nuclear authorities who were deployed to Japan were able to establish a working relation with TEPCO, they relied on information filtered through the Japanese government, which in the first few days was scarcely available: the only real-time information the U.S. had access to was a data stream on the MEXT website, and second-hand reports from NISA and other Japanese government agencies. At this time even the Japanese government did not know how bad the situation was, since TEPCO was downplaying the magnitude of the crisis even while the situation at the Daiichi plant continued to deteriorate.
Prime Minister Kan would eventually lose his job to the crisis, as confidence in the government plummeted, but in the early days of the crisis, he was notable for challenging the TEPCO officials, chastening them to be more forthcoming with information, and demanding action in the face of their intransigence. In June 2011 it was revealed that even though he had ordered them to dump seawater into the reactors, the TEPCO officials defied this order, realizing that the saltwater would render the reactors unusable, and the plant a total loss.The reactors were brought under tenuous control only when Yoshida Masao, the plant manager, ignored orders from his superiors and inundated the reactors.
The conflict between the Kan administration and the TEPCO officials reached an apex on March 15th, when TEPCO’s president Shimizu Masataka announced that TEPCO intended to withdraw from the plant due to the increasing radiation exposure to its employees. Kan’s insistence that TEPCO maintain operational control at the plant site may have prevented a much larger catastrophe. When TEPCO asked permission to withdraw from the plant, they may have been indicating that they were merely relocating to an operational center outside the plant, with a skeleton staff of workers to remain at the Daiichi Facility to monitor equipment and implement actions that could only be done on-site.10But to Kan, who had already endured TEPCO's inordinate delay in venting reactor #1 and defiance in putting saltwater on the reactors, this alleged strategic disencampment to a facility off-site was the culmination of conflict that had started within hours of the plant blackout, and was taken as an abandonment of responsibility.
The question of whether TEPCO intended to entirely abandon the plant or only partly withdraw remains unresolved. The March 2012 “Rebuild Japan” independent report on the Fukushima crisis by a group of former government officials discusses this issue at length, and while they note that various parties indicated that they thought TEPCO was signaling total withdrawal, TEPCO officials contest this claim and after careful consideration, the report – and other subsequent governmental and independent reports -leave this matter unresolved. In retrospect, the true intentions of TEPCO remains obscure, but this dispute was important because it demonstrated that PM Kan did not trust TEPCO to fulfill their duties, and it established a dynamic of accusation and distrust between the principal players and organizations at the center of the crisis.
In subsequent reports both governmental and independent panels accused Kan of micro-managing the crisis, by intruding on the plant administrators charged with handling the situation, blurring the chain of command and unduly complicating decision-making at the worst possible time.Had the situation been under even tenuous control, such accusations might seem warranted, but there was scant indication that TEPCO had the situation in hand, and even with their active involvement, the situation continued to deteriorate and appeared to be sliding toward a catastrophic disaster that threatened the entire country.
Irrespective of the validity of these competing claims, both the Kan administration and the U.S. government experts who were monitoring the situation were convinced that TEPCO was intending to withdraw from the site, and exerted considerable pressure on TEPCO to remain, with Kan essentially requiring them to maintain sufficient staff to manage the operation. The implications for this were dire for the TEPCO staff, as the magnitude of the nuclear accident was growing more ominous, with no resolution in sight, and the remaining staff faced the prospect of lethal doses should they remain. Given the stakes involved, and as a way to provide legal cover for the implications of consigning plant workers to die on the job, the Japanese government simply raised the official threshold standards - the maximum legally allowable dose - for radiation workers at the plant. By utilizing deeply rooted sentimental notions of obligation, the "Fukushima Fifty" (actually there were seventy five workers who remained; the "Fukushima Fifty" was a snappy media created alliteration that helped sell the story) who remained were enlisted in service of a heroic trope that put a human face on TEPCO and allowed the Japanese government to claim the moral high ground (at least over TEPCO), while providing a means of addressing the crisis at the most crucial moment.
It was into this fracas that the U.S. and the other principle players involved in the crisis entered as they futilely attempted to glean information upon which they could make an assessment that would productively orient their actions. Foreign entities who were frantically trying to gather information saw a demoralizing situation: a utility who had lost control of the plant, who seemingly were incapable of taking effective remedial action and who were fighting with the Japanese government while the plant reactors fell like dominos, with no end in sight.
On the morning of March 16, a surveillance helicopter flying over the Daiichi reactors measured 4 sieverts per hour, a reading that alarmed the U.S. nuclear experts, giving further evidence that the spent fuel pool 4 was compromised and the pool was dry. A U.S. government nuclear expert who was directly involved in the U.S. government's radiation assessment of this situation said:
At 100 meters away it (the helicopter) was reading 4 sieverts per hour. That is an astronomical number and it told me, what that number means to me, a trained person, is there is no water on the reactor cores and they are just melting down, there is nothing containing the release of radioactivity. It is an unmitigated, unshielded number. (Confidential communication, September 17, 2012).11
Within hours of this, the U.S. authorities became convinced that TEPCO was intending to leave the plant.
The prospect of TEPCO withdrawing from the plant focused everyone’s attention, as this would have truly been the nightmare scenario that alarmist pundits had been suggesting. Had TEPCO withdrawn operational staff from the Daiichi facility, all the reactors and spent fuel pools would have eventually melted down, releasing such severe levels of radiation that eventually the staff at the Daini facility (located 11.5 kilometers south of the Daiichi NPP) would also be forced to withdraw, with the result being that all the reactors and spent fuel pools at this plant would also have melted down. Given the fact that the spent fuel pools contain approximately 5 – 6 times more radionuclides than a working reactor, this would have been orders of magnitude more severe than the Chernobyl accident. It was with this in mind that the Japanese government discussed evacuating Tokyo. Alarmed at this possibility, in the U.S. embassy planning began to put thousands of Americans on the decks of the aircraft carriers to get them out immediately.
For the U.S. government, this would have jeopardized their ability to maintain the military base structure in Japan in the long term, an unthinkable prospect that would have compelled them in the short term to fully engage in the task of sorting the reactor crisis (despite the prospect of incurring lethal doses in the process), in coordination with the Japanese Ministry of Defense. Despite PM Kan's rage at TEPCO's defiance, from the vantage point of American radiation experts who were looking at the dramatically rising radiation levels, neither TEPCO nor the Japanese government fully appreciated the implications of TEPCO's announced withdrawal. Although this has not yet been revealed to the public due to diplomatic sensitivities, backstage a series of contentious communications passed in short order between the U.S. Pacific Command (PACOM), the U.S. State Department (via U.S. Ambassador Roos), the Japanese Ministry of Foreign Affairs, the Prime Minister’s office and TEPCO about the implications of TEPCO leaving the plant. In response to diplomatic pressure from the U.S., along with the recognition of what this might forebode for the SDF and the American military forces in Japan (and therefore the US-Japan Alliance), Kan flatly demanded that TEPCO officials remain at the plant.
This was an extremely sensitive diplomatic moment in the history of US-Japan relations. As an autonomous state, Japan could not be compelled to heed the U.S. government's desires, even if they were scientifically grounded and pragmatically necessary. From the beginning of the crisis, the NRC, as a U.S. government federal agency whose scientific expertise is always modulated against its political influence, took pains to remain neutral and only offer advice when called upon, serving as a resource to the Japanese government. The NRC staff who arrived in Japan were directed to work through the appropriate diplomatic channels and deal cautiously with their counterparts in the Japanese nuclear industry. On March 14th, just a day before the U.S. learned TEPCO was planning on leaving the Daiichi plant, the NRC sent a missive to its staff and other U.S. nuclear experts in Japan that defined the parameters within which U.S. agencies were expected to operate in Japan:
1) This remains a Japanese response and NRC’s role will be to support the Japanese Emergency Responders in a manner that is appropriate.
2) NRC needs to be the primary contact with NISA and JNES because of our long-standing relationship
3) Public statements we make going forward will have enormous credibility, extreme caution will be necessary
We have now been asked by Japan to provide assistance to their Regulatory authorities and other emergency responders. This was undoubtedly an extremely difficult decision for the Japanese who had up to this point been among the top nuclear leaders in technical expertise, especially in seismic and tsunami matters.
The Japanese are now in their fourth day of responding to these

Abstract
The nuclear disaster in Fukushima which followed in the wake of the 3/11 Tohoku earthquake and tsunami has given rise to one of the most significant public health crises in modern world history, with profound implications for how nuclear energy is perceived. This paper analyzes the most dire phase of the Fukushima nuclear crisis, showing how the level of risk was assessed by nuclear experts and state-level actors who worked largely out of view of public scrutiny. In addition to examining how the accident progression in the reactors was addressed and conveyed to the general public, the paper addresses how the exclusionary zones were determined by Japanese and foreign governments in Japan. As the crisis unfolded and efforts to bring the reactors under control were initially proving ineffective, concerns increased that radiation dispersion was unmitigated, and with radiation monitoring by the U.S. military indicating levels significantly beyond TEPCO’s conservative assessments, the United States broke with Japan, recommending an 80km exclusionary zone, and initiating military assisted departures for embassy staff and Department of Defense dependents from Japan. These actions deviated significantly from Japan’s assessments (which had established a 30km evacuation zone), creating a dynamic where the U.S. provided technical consultation for the nuclear response while striving to maintain a delicate diplomatic balance as they attempted to impose a qualitatively different crisis management response. Because this crisis had significant implications for Japan's international relations, diplomatic considerations have helped to suppress the complex, often fractious relations between Japan and foreign governments - especially the United States - whose collective efforts eventually turned the tide from managing the nuclear meltdowns to ameliorating their long-term consequences. Based on interviews with political officials in both the Japanese government and foreign embassies in Japan, and nuclear experts and military officers who worked the crisis, the paper analyzes how technical assessments drove decision making and were translated into political policy.

Introduction
This paper analyzes institutional response to the Fukushima nuclear disaster, looking at how experts and key decision-making elites in the United States assessed the crisis and set policies as representatives of their organizations. In particular, it examines two related issues: the reactor meltdowns and the dispersion of radioactive fallout, and analyzes the political consequences of the divergent interpretations which developed in the first few days of the crisis around these issues. The framing of these central issues helped construct the general perception of risk that prevailed in this phase of the crisis, and provides a reference point against which to measure subsequent views as the crisis evolved over the longer term. The paper touches on the differences in perception between various foreign governments and examines the political implications of the crisis for international alliances in Japan.
In addition to examining how the accident progression in the reactors was addressed and conveyed to the general public, the paper will discuss how the exclusionary zones and evacuations from areas in close proximity to the Daiichi Nuclear Power Plant (NPP) were determined by Japanese and foreign governments in Japan. As the crisis unfolded and efforts to bring the reactors under control were initially proving ineffective, concerns increased that radiation dispersion was significantly beyond what TEPCO was indicating, and as a result, the United States recommended a 80km exclusionary zone and initiated military-assisted departures for embassy staff and Department of Defense dependents from Japan. These actions deviated significantly from Japan’s assessments (which had established a 30km evacuation zone), creating a dynamicin which the U.S.providedtechnical consultation for the nuclear response whilestriving tomaintain a delicate diplomatic balance as it attempted to impose a qualitatively different crisis management response.
This analysis is based primarily on in-depth interviews with diplomats in foreign embassies, military officials, journalists, nuclear scientists, and scholars, and examines how their collective narratives evolved in interaction with public sentiment as the crisis unfolded. The scope of the analysis is focused on the reflective perceptions of actors as they attempted to make sense of the crisis retrospectively after the 3.11 disasters. Because of diplomatic sensitivities and because some of the experts whose perspectives are represented in this analysis are constrained by organizational obligations that preclude them from revealing their identity, some of the sources remain confidential. In each case in which the identity of a source has been withheld, the information has been verified by independent sources.
"Meltdown" at Fukushima Daiichi
In the fitful hours after Japan experienced its largest ever recorded earthquake on March 11, 2011, the coastline of Tohoku lay in ruins from a tsunami that swept entire towns out to sea, resulting in the death of almost 20,000 people. As the world stood transfixed by the scale of devastation wrought by the tsunami, Japan ramped up its disaster management assets to address this crisis, coordinating its efforts with foreign governments and humanitarian relief organizations. While the international community initially mobilized to offer support for tsunami relief efforts in Tohoku, attention soon turned to the Daiichi nuclear power plant in Fukushima.
In retrospect, the condition of the Daiichi plant in the most dire phase of the crisis seems readily transparent, as an unending litany of bad news has cast the situation in such continuing negative connotations that, like Chernobyl, Fukushima has taken on talismanic connotations to serve as a symbol of nuclear dread. But in the first few days of the crisis, with little meaningful information being provided amidst the disorienting impact of the earthquake and tsunami, and TEPCO offering assurances that were uncritically passed on by the government and a docile press, hope remained that the situation could be brought under control. This wishful thinking was soon made irrational by the explosion of the outer containment structure of reactor #1, which was so powerful (the explosion broke windows 3km from the plant) that both plant workers inside the Daiichi complex and nuclear experts watching from afar initially believed that the reactor core itself had exploded.
With the explosion of the reactor #1 building there was no doubting the significance of this crisis, but calibrating the actual risk and danger that this presented to the general public was a moving target, with competing risk narratives that developed almost immediately after the initial news reports were released that the Daiichi and Daini nuclear power plants in Tohoku were in trouble. In the first few days of the nuclear crisis the information made available to the public was confusing, contradictory and frustrating. Despite a massive explosion that destroyed the outer, secondary containment structure of the Daiichi reactor #1 building, soon to be followed on the next day by a similar explosion of the reactor #3 building, TEPCO insisted that the primary reactor core containment was intact and that there were no releases of radiation that posed a threat to public health. Initially, conjecture held sway, with the foreign media challenging the Japanese press corps, who did little more than pass along TEPCO's announcements, essentially serving as a PR agency for the utility.
By this time, the Japanese and foreign media reportage characterized the situation as dire, even as the TEPCO officials and government were staging press conferences that offered platitudes of assurance while conveying facts that contradicted these statements. For the reporters who covered the crisis, the information provided by the utility was incoherent, contradictory and alarming. At the Wall Street Journal (WSJ) offices in Tokyo, senior editors debated how to characterize the crisis. When the government spokesman Edano Yukio conceded on March 13th that one of the reactors might be in “meltdown,” the WSJ editors noted that the nomenclature of “meltdown” as a label to describe the situation was culturally distinct, with different nuances of meaning between the Japanese term “炉戸溶融 (ろしんようゆう)” and the Western notion of a “meltdown,” which carried more ominous connotations than the straightforward transliteration of the word “meltdown” into Japanese.1
The Merriam-Webster dictionary defines the term “meltdown” as including “[1] the accidental melting of the core of a nuclear reactor; [2] a rapid or disastrous decline or collapse; [3] a breakdown of self control, (Merriam-Webster Dictionary, 2012), and the Oxford English Dictionary explains that “a meltdown was originally a catastrophic accident in a nuclear reactor, but this literal meaning has been swamped by the figurative sense of ‘a disastrous collapse or breakdown’. The term is now used metaphorically to refer to a chaotic loss of control, which is derived from the accidents at Chernobyl and Three Mile Island, where the reactors “ran away” from operator control, releasing significant amounts of radiation as a result of their errors. These accidents are now widely regarded as being the result of institutional failure, and TEPCO’s parsing of the term may have been a way to skirt the issue of responsibility by placing the emphasis only on the melting of nuclear fuel, rather than their own loss of control of the plant.
Although the term “meltdown” is in common usage, and was invoked by the press almost immediately after the crisis began, within the scientific community this term is not recognized as a scientifically meaningful description. The term is not included in the International Atomic Energy Association’s 224 page “Safety Glossary” which enumerates terminology used in nuclear safety and radiation protection, and the term “partial core melt” is used only once to describe a Level 4 “Accident With Significant Off-site Risk,” as indicated by the International Nuclear Event Scale (INES), which charts the levels of magnitude of nuclear “events”. The scale is an indication of the inherent industry bias of technical description, denuded of adjectives or critical phraseology that might be construed as danger. The International Atomic Energy Association (IAEA) refers to this as “a simple scale, designed for promptly communicating to the public in consistent terms the safety significance of events at nuclear facilities" (my emphasis).
On May 24, 2011 on the eve of a visit by an IAEA delegation, TEPCO officials announced that their data indicated that three of the reactors had in fact experienced meltdowns within hours of the loss of power following the tsunami. At this press conference, the issue of how this was previously characterized was revisited, with TEPCO now claiming that the meltdowns could only then be confirmed, and that they had previously suggested this possibility in reactor #1 on May 14, 2011. The media coverage of this revelation challenged TEPCO’s motives for revealing this information months after the fact, suggesting that this was in deference to international pressure, as a face-saving gesture directed toward the visiting delegation of IAEA ministers. Alternate media and independent reporters had been asserting the possibility of multiple meltdowns from the beginning, and while this possibility was presented by mainstream press as well, these stories were tempered by the acknowledgement that with no ability to see within the reactors, these scenarios were speculative at best.
For nuclear experts, the debate over whether or not meltdowns had occurred was largely a political controversy being played out in the echo chamber of the mass media, as it was taken as a given that significant meltdowns had started early in the trajectory of the reactor accident progression (TEPCO would late specify that within 8 hours after the loss of power, meltdowns had occurred). In the scientific community it has long been recognized that at high temperature the zirconium alloy cladding that holds the fuel rods melts, drawing off oxygen from the surrounding water and liberating hydrogen, a highly volatile gas. Despite the venting of radioactive gases in the Three Mile Island (TMI) accident, the most ominous threat that the accident posed was a hydrogen explosion that could have blown the reactor out, leading to a catastrophic release that would have been much more severe than what actually transpired. Through intense scrutiny it was determined that the infamous hydrogen bubble that built up inside the reactor #2 building at TMI could not explode due to a lack of oxygen, and remedial efforts were able to reduce the size of the bubble until it was no longer a threat. But in Fukushima, the powerful explosions that destroyed the buildings housing the Daiichi reactors could only have happened if a core melt was significant enough to release high levels of hydrogen gas, and the subsequent explosions were proof positive that catastrophic meltdowns had already occurred. As a result, while the media debated the relative chances of a meltdown and quibbled over the nomenclature, the nuclear experts who worked the crisis knew early on unambiguously that the Daiichi plant was in deep trouble, and mobilized their resources accordingly.
As the Daiichi plant’s condition rapidly deteriorated, it became clearly evident that the situation was beyond the control of the TEPCO administrators, which undermined their authority, lending credence to the widespread perception that they were not forthcoming with information. Government officials and TEPCO spokesmen claimed that they had been withholding this information in order to prevent panic in the early days of the crisis, but this revelation was taken as evidence that officials were deceiving the public and that TEPCO was more concerned about protecting its investments than it was in ensuring public safety.
For the foreign press, the devastation of the tsunami was the initial focus of coverage, diverting attention from the nuclear crisis, which in the first few days remained opaque, while the implications of the tsunami were clearly evident. Although major media conglomerates such as Reuters, The Wall Street Journal and the Associated Press had the resources to divide coverage between the two conjoined disasters, other major media organizations such as the New York Times, The Times of London, the BBC and CNN have scarce resources on the ground in Japan (most of the Asia bureaus for major media outlets have moved from Japan to China in the last decade), and the senior editors for these publications were mobilized to the coastland of Tohoku to cover the tsunami.
The media followed a pattern that played out in the foreign embassies in Japan as well, in which nuclear experts in their home countries provided consultation for assessing the situation. But while these authorities may have had considerable experience dealing with nuclear issues, they had virtually no culturally contextualized knowledge of Japan, and in the short-term had no access to more nuanced local information of what was transpiring at the Daiichi plant. Organizational elites, both in the diplomatic corps and in the foreign media, relied primarily on the Japanese mainstream media for more specific information, tempering this with the widely divergent, often random reports that were filtering out through social media, which, being less constrained by organizational vetting and mainstream considerations, tended to be more alarmist, amplifying the analysis to interpretations that often were dismissed because they were at the time unwarranted by the facts (which, after all, were not available at that time). In retrospect, many of these reports have been vindicated by information that has gradually become available as a series of revelations by disgruntled former industry officials, retired government authorities and scholars has given credence to views that had previously been seen as overwrought.
Radiation Plume Politics
At Three Mile Island, it was not until three years after the accident that plant managers were able to look into the reactors and determine that the core of reactor #2 had melted down. At Fukushima, with a station blackout and the plant in disarray as staff frantically tried to recover power, the situation in the first days of the crisis remained fluid, with little meaningful information to convey. If the actual situation was unclear to workers inside the plant, it was entirely opaque to those outside, including the diplomatic corps at embassies in Japan and nuclear authorities from abroad, who were pressing the Japanese government to provide specific information. In addition to concerns about what was developing inside the reactors, a central issue of risk assessment – and trust - was related to the spread of radiation disseminating from the plant. After a frustrating delay in venting reactor #1 that pitted Prime Minister Kan Naoto against a recalcitrant TEPCO management that was internally divided and uncooperative, evacuations from nearby the plant commenced with little government guidance and no information made available that could help guide prefectural authorities in their actions.
The Japanese government had established a computer modeling “System for Prediction of Environment Emergency Dose Information (SPEEDI)” in 1980, following the Three Mile Island nuclear accident, and the system remained functional throughout the nuclear crisis. SPEEDI was designed to provide detailed computer modeling projections of how weather patterns dispersed radioactive fallout into the environment.
As fears about the reactors heightened and TEPCO prepared to vent reactor #1, on March 12 the government evacuated four towns located nearby the reactors, increasing the evacuation zone from 2km, as decided in the evening of the previous day, to 10km (6.2 miles, cf. Table 2). Two of the towns – Futaba and Okuma – were assisted in the evacuation, with the government providing buses to transport citizens. Despite this initial support, refugees from Namie and Tomoika, who were in evacuation areas initially only 8km (4.4 miles) from the plant, were thereafter left to fend for themselves with neither direction nor support offered by the Japanese government, and fled northwest, right into the path of the radioactive plume, just where SPEEDI, had it been implemented, would have predicted the fallout would go. This scandal firmly linked the Japanese government to TEPCO as corrupt and incompetent on fundamental issues of radiation assessment. Whereas the hapless handling of the reactors had been attributed to a lack of regulatory oversight that prefigured TEPCO's chaotic response to the disaster, the SPEEDI scandal was seen as being the result of incompetence at the highest levels of government, betraying a lack of concern for the people most at risk from the nuclear disaster.
Despite having elaborate evacuation plans that previously had been coordinated with TEPCO, Baba Tomatsu, the mayor of Namie, initially learned of the nuclear disaster by watching it on TV and was bitterly resentful of the lack of consideration that put his village at risk:
There was no coordination with the Japanese Government. Nothing. They didn’t tell us where to evacuate. Nothing. Namie machi did everything by ourselves. And, disappointingly, because we didn’t hear anything from the government – no advisories – we used anything that we had—school buses and such—to move people out of the area. People’s cars were destroyed by the tsunami so we placed those people in those buses. At that time, the people who had ways to evacuate had already evacuated, to Miyagi, or Yamagata prefecture. So the 21,000 population were all scattered like a bee’s hive.2
Because we had no information we were unwittingly evacuating to an area where the radiation level was high so I'm very worried about the people's health. I feel pain in my heart but also rage over the poor actions of the government… It's not nice language but I still think it was an act of murder. What were they thinking when it came to the people's dignity and lives? I doubt that they even thought about our existence.3
The New York Times helped break this story in the foreign media in a critical analysis of how officials withheld information and the subsequent influence this had on Japanese public opinion toward the government. Onishi Nori, one of the reporters who worked the story, emphasized the qualitative shift in orientation that this brought to Japanese politics:
In the first couple of months after 3.11, the public inclination was to still trust what the government was saying and what the media was describing, but that started to breakdown by May, and that was reflected in public opinion polls at that time.
The recognition of the meltdown was big. When the Japanese government finally acknowledged that there was a meltdown in mid-May, the Japanese people said, “what does this mean?” The foreign media had written about the meltdown in the first week of the disaster, and the Japanese government had criticized the foreign media for being alarmist, and here they were a few months later saying 'oh yeah, I guess there were meltdowns.'
That was a key moment, as was the SPEEDI issue. That breakdown in trust toward the government, toward the media – you never really saw that before last year. For the first time, I had many people say to me 'thank God for the foreign media, they are the only ones telling the truth'.4
Elements of this story had already been covered in the Japanese media, dating to April, 2011, when Kosako Toshiso, a former professor at the University of Tokyo and member of the government’s impromptu advisory group on radiation, resigned in protest over the government’s mishandling of SPEEDI, linking it to subsequent arbitrary loosening of radiation danger threshold standards. Kosako’s resignation was the first significant crack in the public façade being maintained by the government, and this story increased in significance as it was associated with government deception and collusion. By April, an Asahi Shimbun public opinion poll indicated that only 21% supported the Kan administration with 60% opposed, and in response to the question “Do you think the government’s dissemination of information about the accident in the Fukushima Daiichi nuclear power plant was appropriate?” only 16% answered in the affirmative, with 73% saying that it was inappropriate.
With the SPEEDI data, it appears that social media was instrumental in making the system known outside a small circle of bureaucrats who were reluctant to act on the information, and who themselves were not initially aware of the database because this information was compartmentalized in other offices and no one was discussing it. With no one asking the right questions to the right people, the information lay dormant. The SPEEDI data was not initially conveyed to local officials in Fukushima, but was known to some Japanese government officials in the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the government office under which SPEEDI is administered. Although the staff who were compiling the information for the SPEEDI computer modeling had data in-hand by the first day of the accident, they withheld the predictions, claiming a lack of certainty about its accuracy due to incomplete data (the model depended in part on data from the nuclear plant, but with the power supply down, this was not available to factor into the overall assessment).
Suzuki Kan, the Vice Minister of MEXT, the agency in charge of radiation assessment, did not know about SPEEDI and learned of it only when Hayano Ryugo, a particle physicist and Chairman of the Department of Physics at the University of Tokyo, approached him to inquire how the SPEEDI data was being utilized and to request access to the data so that he could run an analysis. Minister Suzuki thereafter made internal inquiries and confirmed on March 19th that the system was operative but not being properly utilized, but in the interim, Professor Hayano began Tweeting about SPEEDI, drawing attention to the issue.5
Yahoo Japan had recommended Hayano on their top-page as a person of note shortly after the nuclear crisis began, and thereafter, his following grew exponentially to reach a broader public audience. These Twitter posts also came to the attention of Shikata Noriyuki, who at the time of the nuclear accident was Deputy Cabinet Secretary for Public Affairs and Director of Global Communications at the Prime Minister’s Office. Secretary Shikata informed Deputy Chief Cabinet Secretary Fukuyama Tetsuro on March 15 and information about SPEEDI was then conveyed to the U.S. Embassy and military through the Ministry of Foreign Affairs. SPEEDI was not revealed officially to the general public until March 23, but by then, information about this system was spreading through social networks and into the mainstream media.
This information flow became an important feedback loop, providing information to MEXT officials about their own system. Shikata, who after being approached had started following Hayano’s tweets, and began consulting with him about technical matters to assess the accuracy of the scientific data they were attempting to convey at governmental press conferences. Shikata then asked Hayano to help him inform the foreign media because of his bilingual language proficiency and his ability to communicate about technical issues clearly and efficiently.6
It is by now a common belief that the confusion that reigned in the immediate aftermath of the tsunami and nuclear crisis was due to a lack of information. While this may have been the case for the general public who lacked access to meaningful information and were relying on media reports, TEPCO and the Japanese government had multiple sources of information that could have helped contextualize and explain the efforts they were taking to address the situation. Rather, TEPCO was initially reluctant to acknowledge the seriousness of the crisis and instead of explaining the situation, simply provided raw data without an interpretative frame that would have allowed non-specialists to make sense of the information and assess their claims. William Sposato, the Deputy Bureau Chief of the Wall Street Journal in Tokyo characterized the reaction of many of the foreign journalists who were working the crisis at this time:
I don’t know of an instance where they lied deliberately, but their news conferences went on forever, they were filled with useless information, and they were unwilling to distill that information. They knew more about this than anyone else, and they could have taken the body of information they had and said ‘this is what we think is the most significant information that you need to know – this is the line we think you should look at’”. Unbelievable amounts of data, and the data would keep shifting: ‘today we have becquerels per square meter 100 yards from the plant. Tomorrow, we have millisieverts per hour a mile away from the plant.’ Is it getting better or is it getting worse? Their data gathering was just all over the map.7
Ironically, while TEPCO was “drowning journalists with data” (as Christoph Neidhart, the German daily Sueddeutsche Zeitung Tokyo bureau chief who attended their daily press conferences put it),8 Hayano’s Twitter posts reached a large and diverse audience, and was all the more persuasive because of its brevity. Where it not for Hayano, cogently encapsulating complex technical information into 100 character tweets and talking with the appropriate officials, the information may not have come out.
The SPEEDI contretemps, as with the divergent interpretations about the condition of the reactors previously discussed, indicates the complexity of how information develops and is utilized in complex, “normal accidents”. The multiple government and embassy offices, rather than being integrated under a common chain of command as part of an integrated crisis management system, compartmentalized information in silos, not only ineffectively communicating outside their respective bureaucracies, but often not discussing important facts even among themselves. The press helped link these together, as it pushed and prodded for information, compelling officials to explain their actions and account for their policies.
While the Japanese press attempted to burrow down into the details of the organizational chaos, the foreign press continued to amplify the crisis, framing it in terms that would appeal to foreign viewers who were distracted from the tsunami because of the crisis and disinterested in the internecine politics of obscure bureaucratic officials. Taken together, these combined into a compelling narrative arch, as the Japan-based journalists revealed bureaucratic ineptitude that provided a grounding in reality to the more critical views that were gaining traction. Lacking contextual perspective, and with scarce information available in any case, the foreign press played up fears of apocalyptic doom. Lacking information about what was really transpiring at the Daiichi plant and living through the uncertainty and chaos in those early days after the earthquake, the local press looked for explanation in the actions of specific organizational elites, and found little of worth. These views aligned in the assessment of foreign authorities, who, doubting the information they were receiving, began to distrust the leaders who were providing it.
The controversy over the SPEEDI data was later compounded by the disclosure that on March 14 this data, which had been withheld from local Japanese officials and those in the path of the fallout (the Japanese public did not find out until 9 days later), had been released in hourly reports to the U.S. embassy and military who were working on relief efforts in the area. For many, this hardened views that TEPCO and the Japanese government were more concerned about vested interests and state-level political concerns than they were about the well-being of their most vulnerable citizens. It also raised questions about what was really transpiring behind the scenes while these entities ineptly attempted to manage the story and project an increasingly implausible facade of control.
Negotiating Risk: International Divergence in Radiation Assessment
In the immediate aftermath of the tsunami, an unprecedented relief effort comprised of domestic and international NGOs, unaffiliated citizen volunteers, and government associated organizations from 116 countries descended on Japan to provide disaster relief in the Tohoku region. This impressively international outpouring of support demonstrated genuine humanitarian concern, and it cast the most unambiguously positive light on the 3.11 crises. While initially these tsunami relief efforts stood as a salutary example of international cooperation, as the nuclear crisis unfolded and eclipsed attention on the aftermath of the tsunami, this narrative turned toward one of confusion, suspicion and deceit, with TEPCO - and, by association, the Japanese government - being cast in a negative light, not only by Japanese citizens, who were increasingly feeling misled by government authorities, but by foreign governments, who were frustrated by the lack of information being provided by TEPCO and Japanese government officials about what was actually transpiring at Fukushima Daiichi.
Because of its long-standing strategic political alliance with Japan, buttressed by the largest array of military bases outside the continental U.S. and the only forward-deployed nuclear aircraft carrier group in the U.S. military, the United States was the most significant foreign responder in tsunami relief efforts and provided the most meaningful consultation and logistical support in the nuclear crisis. The U.S. Pacific Command (PACOM), working in coordination with USAID and other federal agencies, was intimately involved in relief efforts in Tohoku from the beginning, and working closely with the Japan Self-Defense Forces (SDF), were significant first-responders to coastal villages that had been swamped by the tsunami. These joint operations in total involved 140 U.S. aircraft, 19,703 personnel and over 20 American naval ships, which represented a significant portion of the U.S. 7th fleet Naval Forces. U.S. troops participating in Operation Tomodachi (Friendship) worked in close coordination with the Japanese Ministry of Defense and SDF, a rare moment in the often fractious relations the U.S. military has experienced in Japan. Japanese public sentiment toward the U.S. soared as a result, with 84% of Japanese polled in the Cabinet Office’s annual report saying they had friendly feelings toward the United States, the highest tally by far since the survey began in 1978. These findings were replicated in a poll commissioned on June 9 by Japan’s Foreign Ministry (84% approval), and in a Pew Global Attitudes poll (85% approval) taken on June 1, 2011 which found similar results.
The U.S. government and military support for tsunami relief efforts through Operation Tomodachi have garnered considerable attention, but less is known about the role the U.S. military played in helping to respond to the Fukushima nuclear crisis. With the Sendai airport rendered inoperable by the tsunami, the U.S. Navy's Ronald Reagan aircraft carrier group, parked off the coast of Fukushima, served as a fueling platform and staging area for tsunami relief, at which time military personnel were exposed to radiation emanating from the reactors. As the wind was blowing out to sea for the first couple of days after the onset of the crisis, aside from local communities near the Daiichi facility, servicemen on this nuclear powered aircraft carrier were among the first to be exposed to the radiation plume from the explosion of the Reactor 1 building on March 12. The exposure levels both on the ship and on the shoes of US servicemen who had temporarily landed on a Japanese command ship at 50 nautical miles from the plant were unexpectedly high, provoking the carrier group to back off from 60 to 180 nautical miles from the plant.
In transcribed telephone conversations between U.S. based federal government officials, nuclear authorities, U.S. embassy officials in Tokyo and military staff in the Pacific Command (PACOM) made available through the Freedom of Information Act (FOIA), the U.S. government response to the nuclear crisis can be seen in real-time as it played out over the course of the first month of the crisis:
ADMIRAL DONALD: (...) Earlier this evening, as the USS Ronald Reagan was operating off the coast of Japan, we - the ship just arrived. We had given the ship some guidance as far as positioning was concerned to stay clear of the area of the potential plume, basically told her to stay 50 miles outside of the radius of the -- 100 miles -- excuse me -- 50 miles radius outside of the plant and then 100 miles along the plume with a vector of 45 degrees. The ship was adhering to that requirement and detected some activity about two and a half times above normal airborne activity using on-board sensors on the aircraft carriers. So that indicated that they had found the plume and it was probably more significant than what we had originally thought. The second thing that has happened is we have had some helicopters conducting operations from the aircraft carrier and one of the helicopters came back from having stopped on board the Japanese command ship in the area, and people who had been on -- were on the helicopter who had walked on the deck of the ship, were monitored and had elevated counts on their feet, 2500 counts per minute. But I wanted to get you guys on the line and my expert on the line so we can get the data and then the proper people notified.
MR. PONEMAN: Okay, I have a couple of questions. Number one, in terms of the level of radiation that you are picking up, what's the delta between that and any information we have from the Japanese or other sources of what the level of radiation would be, given the venting and so forth that we know has occurred?
MR. MUELLER: So -- this is Mueller -- the sample that was taken and then what we detected, we were 100 nautical miles away and it's -- in our terms it's -- compared to just normal background it's about 30 times what you would detect just on a normal air sample out at sea. And so we thought -- we thought based on what we had heard on the reactors that we wouldn't detect that level even at 25 miles. So it's much greater than what we had thought. We didn't think we would detect anything at 100 miles.
MR.. PONEMAN: You didn't think you'd detect anything at 100 miles. Okay, and then in terms of the regulations and so forth of people operating in these kinds of areas, I forget some you know, acronym for it, PAG (Protective Action Guidelines) or something, how do the levels detected compare with what is permissible?
MR. MUELLER: If it were a member of the general public, it would take -- well, it would take about 10 hours to reach a limit, a PAG limit.
MUELLER: Right. For a member of the public.
PONEMAN: Right. You mean, at the level you detected?
MR. MUELLER: Yes sir. But 10 hours, it's a thyroid dose issue.
MR. PONEMAN: Okay, but the net of all this is that the amount of release that is detected by these two episodes whatever you would call them, is significantly higher than anything you would have expected what you have been reading from all sources?
MR. MUELLER: Yes sir. The number specific number we detected was 2.5 the times 10 to the 88 minus nine microcuries per milliliter, airborne, and that's particulate airborne. It is -- we did not take radioiodide samples so I don't know that value, but this is particulate airborne...
MR. PONEMAN: Tell me again exactly how you picked up these two forms of samples.
MR. MUELLER: We have automatic detectors in the plant that picked up -- picked up the airborne, and all of our continuous monitors alarmed at the same level, at this value. And then we took portable air samples on the flight desk and got the same value.
ADMIRAL DONALD: These are normally running continuous detectors, continuous monitors that run in the engine room all the time, monitoring our equipment.
MR. PONEMAN: These are detectors on the Reagan?
ADMIRAL DONALD: On the Ronald Reagan, correct.
MR. MUELLER: Yes sir.
MR. PONEMAN: On the Ronald Reagan. They are there because you have got equipment there that you know, it could emit stuff and while you were there, you picked up stuff that was ambient which indicated that you actually were in the plume?
MR. MUELLER: That's correct.
MR. PONEMAN: And this was -- this was 30 times higher than what you would have expected?
MR. MUELLER: Yes sir.9
With the Daiichi plant still a black box, and only spotty data to indicate the radiation dispersion, the U.S. quickly set up an independent parallel process of acquiring data, utilizing their vast array of military and governmental resources. These included the Department of Energy’s Atmospheric Monitoring System (AMS), on the ground radiation measurement surveys, fixed station radiation monitors, the RQ-4 Global Hawk military drone and classified military surveillance (the Lockheed U-2 high-altitude reconnaissance aircraft and the P-3 Orion maritime surveillance aircraft) and the nuclear aircraft carriers to help with the assessment. In order to make sense of this data, the U.S. relied on Nuclear Regulatory Commission (NRC) administrators, who coordinated with the Department of Energy and the National Atmospheric Release Advisory Center at the Lawrence Livermore National Laboratory in California, analysis by Naval Reactors' experts at their research labs (comprised of approximately 6,000 staff), and an ad hoc collection of loosely affiliated former government specialists, retired military officers (nuclear engineers), scholars and former NRC staff. In order to consolidate these resources into an integrated command structure, the U.S. embassy in Tokyo conceived a “Bilateral Assistance Coordination Cell” (BACC), which met daily and included all USG agencies.
Through diplomatic channels, with U.S. Ambassador Roos representing the State Department, the U.S. attempted to coordinate its response with the Japanese government. This had started soon after the onset of the crisis, focusing on tsunami relief efforts as the Japanese Self Defense Forces (SDF) and the United States Forces Japan (USFJ) developed joint operations using both U.S. and Japanese military bases as staging grounds for mounting their operations. With a keen eye on the diplomatic implications of the crisis, state-level actors took pains to highlight mutual cooperation, despite frustrations that developed backstage as the power outage at the Daiichi plant developed into a full-blown crisis. Until the U.S. nuclear authorities who were deployed to Japan were able to establish a working relation with TEPCO, they relied on information filtered through the Japanese government, which in the first few days was scarcely available: the only real-time information the U.S. had access to was a data stream on the MEXT website, and second-hand reports from NISA and other Japanese government agencies. At this time even the Japanese government did not know how bad the situation was, since TEPCO was downplaying the magnitude of the crisis even while the situation at the Daiichi plant continued to deteriorate.
Prime Minister Kan would eventually lose his job to the crisis, as confidence in the government plummeted, but in the early days of the crisis, he was notable for challenging the TEPCO officials, chastening them to be more forthcoming with information, and demanding action in the face of their intransigence. In June 2011 it was revealed that even though he had ordered them to dump seawater into the reactors, the TEPCO officials defied this order, realizing that the saltwater would render the reactors unusable, and the plant a total loss.The reactors were brought under tenuous control only when Yoshida Masao, the plant manager, ignored orders from his superiors and inundated the reactors.
The conflict between the Kan administration and the TEPCO officials reached an apex on March 15th, when TEPCO’s president Shimizu Masataka announced that TEPCO intended to withdraw from the plant due to the increasing radiation exposure to its employees. Kan’s insistence that TEPCO maintain operational control at the plant site may have prevented a much larger catastrophe. When TEPCO asked permission to withdraw from the plant, they may have been indicating that they were merely relocating to an operational center outside the plant, with a skeleton staff of workers to remain at the Daiichi Facility to monitor equipment and implement actions that could only be done on-site.10But to Kan, who had already endured TEPCO's inordinate delay in venting reactor #1 and defiance in putting saltwater on the reactors, this alleged strategic disencampment to a facility off-site was the culmination of conflict that had started within hours of the plant blackout, and was taken as an abandonment of responsibility.
The question of whether TEPCO intended to entirely abandon the plant or only partly withdraw remains unresolved. The March 2012 “Rebuild Japan” independent report on the Fukushima crisis by a group of former government officials discusses this issue at length, and while they note that various parties indicated that they thought TEPCO was signaling total withdrawal, TEPCO officials contest this claim and after careful consideration, the report – and other subsequent governmental and independent reports -leave this matter unresolved. In retrospect, the true intentions of TEPCO remains obscure, but this dispute was important because it demonstrated that PM Kan did not trust TEPCO to fulfill their duties, and it established a dynamic of accusation and distrust between the principal players and organizations at the center of the crisis.
In subsequent reports both governmental and independent panels accused Kan of micro-managing the crisis, by intruding on the plant administrators charged with handling the situation, blurring the chain of command and unduly complicating decision-making at the worst possible time.Had the situation been under even tenuous control, such accusations might seem warranted, but there was scant indication that TEPCO had the situation in hand, and even with their active involvement, the situation continued to deteriorate and appeared to be sliding toward a catastrophic disaster that threatened the entire country.
Irrespective of the validity of these competing claims, both the Kan administration and the U.S. government experts who were monitoring the situation were convinced that TEPCO was intending to withdraw from the site, and exerted considerable pressure on TEPCO to remain, with Kan essentially requiring them to maintain sufficient staff to manage the operation. The implications for this were dire for the TEPCO staff, as the magnitude of the nuclear accident was growing more ominous, with no resolution in sight, and the remaining staff faced the prospect of lethal doses should they remain. Given the stakes involved, and as a way to provide legal cover for the implications of consigning plant workers to die on the job, the Japanese government simply raised the official threshold standards - the maximum legally allowable dose - for radiation workers at the plant. By utilizing deeply rooted sentimental notions of obligation, the "Fukushima Fifty" (actually there were seventy five workers who remained; the "Fukushima Fifty" was a snappy media created alliteration that helped sell the story) who remained were enlisted in service of a heroic trope that put a human face on TEPCO and allowed the Japanese government to claim the moral high ground (at least over TEPCO), while providing a means of addressing the crisis at the most crucial moment.
It was into this fracas that the U.S. and the other principle players involved in the crisis entered as they futilely attempted to glean information upon which they could make an assessment that would productively orient their actions. Foreign entities who were frantically trying to gather information saw a demoralizing situation: a utility who had lost control of the plant, who seemingly were incapable of taking effective remedial action and who were fighting with the Japanese government while the plant reactors fell like dominos, with no end in sight.
On the morning of March 16, a surveillance helicopter flying over the Daiichi reactors measured 4 sieverts per hour, a reading that alarmed the U.S. nuclear experts, giving further evidence that the spent fuel pool 4 was compromised and the pool was dry. A U.S. government nuclear expert who was directly involved in the U.S. government's radiation assessment of this situation said:
At 100 meters away it (the helicopter) was reading 4 sieverts per hour. That is an astronomical number and it told me, what that number means to me, a trained person, is there is no water on the reactor cores and they are just melting down, there is nothing containing the release of radioactivity. It is an unmitigated, unshielded number. (Confidential communication, September 17, 2012).11
Within hours of this, the U.S. authorities became convinced that TEPCO was intending to leave the plant.
The prospect of TEPCO withdrawing from the plant focused everyone’s attention, as this would have truly been the nightmare scenario that alarmist pundits had been suggesting. Had TEPCO withdrawn operational staff from the Daiichi facility, all the reactors and spent fuel pools would have eventually melted down, releasing such severe levels of radiation that eventually the staff at the Daini facility (located 11.5 kilometers south of the Daiichi NPP) would also be forced to withdraw, with the result being that all the reactors and spent fuel pools at this plant would also have melted down. Given the fact that the spent fuel pools contain approximately 5 – 6 times more radionuclides than a working reactor, this would have been orders of magnitude more severe than the Chernobyl accident. It was with this in mind that the Japanese government discussed evacuating Tokyo. Alarmed at this possibility, in the U.S. embassy planning began to put thousands of Americans on the decks of the aircraft carriers to get them out immediately.
For the U.S. government, this would have jeopardized their ability to maintain the military base structure in Japan in the long term, an unthinkable prospect that would have compelled them in the short term to fully engage in the task of sorting the reactor crisis (despite the prospect of incurring lethal doses in the process), in coordination with the Japanese Ministry of Defense. Despite PM Kan's rage at TEPCO's defiance, from the vantage point of American radiation experts who were looking at the dramatically rising radiation levels, neither TEPCO nor the Japanese government fully appreciated the implications of TEPCO's announced withdrawal. Although this has not yet been revealed to the public due to diplomatic sensitivities, backstage a series of contentious communications passed in short order between the U.S. Pacific Command (PACOM), the U.S. State Department (via U.S. Ambassador Roos), the Japanese Ministry of Foreign Affairs, the Prime Minister’s office and TEPCO about the implications of TEPCO leaving the plant. In response to diplomatic pressure from the U.S., along with the recognition of what this might forebode for the SDF and the American military forces in Japan (and therefore the US-Japan Alliance), Kan flatly demanded that TEPCO officials remain at the plant.
This was an extremely sensitive diplomatic moment in the history of US-Japan relations. As an autonomous state, Japan could not be compelled to heed the U.S. government's desires, even if they were scientifically grounded and pragmatically necessary. From the beginning of the crisis, the NRC, as a U.S. government federal agency whose scientific expertise is always modulated against its political influence, took pains to remain neutral and only offer advice when called upon, serving as a resource to the Japanese government. The NRC staff who arrived in Japan were directed to work through the appropriate diplomatic channels and deal cautiously with their counterparts in the Japanese nuclear industry. On March 14th, just a day before the U.S. learned TEPCO was planning on leaving the Daiichi plant, the NRC sent a missive to its staff and other U.S. nuclear experts in Japan that defined the parameters within which U.S. agencies were expected to operate in Japan:
1) This remains a Japanese response and NRC’s role will be to support the Japanese Emergency Responders in a manner that is appropriate.
2) NRC needs to be the primary contact with NISA and JNES because of our long-standing relationship
3) Public statements we make going forward will have enormous credibility, extreme caution will be necessary
We have now been asked by Japan to provide assistance to their Regulatory authorities and other emergency responders. This was undoubtedly an extremely difficult decision for the Japanese who had up to this point been among the top nuclear leaders in technical expertise, especially in seismic and tsunami matters.
The Japanese are now in their fourth day of responding to these
