Fukushima Diary : [100m3 overflow] Tepco “Abnormality was too slight to notice”Posted by Mochizuki on March 7th, 2014 · No Comments Following up this article.. [100m3 overflow] Contaminated water is removed by “hand-digging” of human workers The abnormality of tank water level trend was too slight to recognize, Tepco stated in the press conference of 3/5/2014. When 100m3 of highly contaminated water overflowed from the tank, the operators were watching the monitor of tank water levels. However they didn’t notice the water overflowing. In the report that Tepco submitted to NRA (Nuclear Regulation Authority) on 3/5/2014, it was simply because the water trend was represented in the scale of 0% ~ 100% on the monitor (See the picture below). Before the tank had the additional contaminated water, it was already 98% full. They therefore didn’t recognize 2% of the increase, which was shown as a “negligible gap” on the monitor. The operators are employed by the different company from the monitor maker. It revealed the fact that Tepco is not supervising even the most basic things in Fukushima decommissioning process. www.tepco.co.jp/tepconews/library/movie-01j.htmlwww.tepco.co.jp/nu/fukushima-np/handouts/2014/images/handouts_140305_04-j.pdfIori Mochizuki fukushima-diary.com/2014/03/100m3-overflow-tepco-abnormality-was-too-slight-to-notice/
