Fukushima plant is estimated to produce 560,000 m3 of radioactive debris by 2027. Tepco released the assumption on 4/7/2014.
Tepco plans to recycle a part of it, but 160,000 m3 would still remain. This is the equivalent of 328 of 25m swimming pools, and Tepco doesn’t have sufficient storage facilities for it. Also, it doesn’t include the parts of reactor buildings or contaminated water tanks. If they end up dismantling a part of the plant buildings or current water tanks, this assumed volume would even increase.
On 4/7/2014, Tepco published the estimate of the potential debris volume produced by 2027. Currently they stock the debris caused by 311, and are going to have to stock more debris from dismantling the leaked contaminated water tanks.
The potential debris volume is 560,000 m3 in total. The highest surface dose is over 30 mSv/h.
Tepco plans to recycle a part of it if the surface dose is lower than 1 mSv/h. The recycled debris would be concrete and subbase course material. They are also to reduce the volume of the steal parts and reuse it as the shielding material or storage container.
However still 160,000 m3 of the debris is assumed to remain to be stocked even based on Tepco’s calculation. It is not announced where the reused material would be consumed either.
They only focus on the shortage of contaminated water storage, but Tepco is also in a serious shortage of radioactive debris storage facilities.
