Contaminated Water Processing at #Fukushima: The Water Was Simply Too “Hot”, EX-SKF, June 19, 2011:
[...] 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”.
[144 x 720,000 / 5,600,000 = 18.5]
Test of decontamination system continues, NHK, June 20, 2011:
[...] TEPCO engineers suspect that the density of radioactive substances in the contaminated water was greater than had been predicted.
They initially thought that the device had absorbed large volumes of oil and sludge containing radioactive material. But in a test conducted on Sunday, high radiation levels were registered for equipment set to the lowest of 3 absorption levels. [...]
Dow Jones: “[T]he high levels of radiation were due to the radioactivity of the water the system was treating,” Tepco spokesman Junichi Matsumoto said.”
