From Asahi Shinbun (1:02PM JST 6/20/2011):
東京電力福島第一原子力発電所で放射能汚染水の浄化装置がトラブルで停止した問題で、東電は２０日、原因は予想以上の高濃度の汚染水が装置に流入したのが原因とみられると発表した。２０日午前中から再度試験をして放射線量を調べる。
TEPCO investigated the contaminated water treatment system that was halted [when the radiation on the Kurion's subsystem exceeded the limit (4 millisieverts/hour) set by TEPCO] and announced on June 20 that the problem was caused by the flow of the water that contained much more radioactive materials than expected. TEPCO is conducting the test again to measure the radiation level.
Well, over 100,000 tonnes of highly contaminated water at Fukushima I Nuclear Power Plant are estimated to contain 720,000 terabecquerels of radioactive materials.
If Kurion's vessel absorbed enough radioactive materials in 5 hours and it should have taken 30 days, as I wrote in my previous post, the water was 144 times as radioactive as the system had anticipated.
If the water actually turns out to be 144 times as radioactive, the Fukushima accident would need a new INES category and should not be placed in the same category (Level 7) as the Chernobyl accident which released only 5.6 million terabecquerels of radioactive materials. Maybe it should be simply called "Level Fukushima".
