– Contaminated Water Processing at #Fukushima: The Water Was Simply Too “Hot” (EX-SKF, June 19, 2011):
for the system to handle, TEPCO found out.
From Asahi Shinbun (1:02PM JST 6/20/2011):
?????????????????????????????????????????????????????????????????????????????????????????????????????????????
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”.

As Robert Alvarez, a former nuclear energy adviser to President Bill Clinton, has written, if these waste containers, euphemistically called “ponds,” were to be damaged in an explosion and lose their cooling and radiation-shielding water, they could burst into flame from the resulting burning of the highly flammable zirconium cladding of the fuel rods, blasting perhaps three to nine times as much of these materials into the air as was released by the Chernobyl reactor disaster. (And that’s if just one reactor blows!) Each pool, Alvarez says, generally contains five to ten times as much nuclear material as the reactors themselves. Alvarez cites a 1997 Nuclear Regulatory Commission study that predicted that a waste pool fire could render a 188-square-mile area “uninhabitable” and do $59 billion worth of damage (but that was 13 years ago).
