Tokyo Electric Power Co. is taking steps to prevent a possible self-sustaining nuclear chain reaction at the crippled Fukushima No. 1 nuclear power plant. [...]
“We expect them to address the public’s concerns by methodically explaining what could happen and how they plan to deal with it,” [Haruki Madarame, chairman of the Nuclear Safety Commission of Japan] said. [...]
TEPCO officials said the rise in temperatures was not steep enough to indicate that criticality had been reached.
[...] TEPCO has assumed a margin of error of up to 20 degrees for the thermometers [...] Therefore, a reading exceeding 80 degrees could mean an actual temperature of more than 100 degrees, compromising the reactor’s status as being in cold shutdown. [...]
“The temperature may have risen because water has not reached part of the fuel since the amount of water through the feed water system decreased and the flow of water changed,” said an official at TEPCO’s Nuclear Power and Plant Siting Division.
