Nov. 3 — Regarding the detection of xenon, TEPCO has “played down the find, saying there was no evidence of a ‘criticality’ in the reactor,” reports the UK’s Channel 4 News, “Now there are concerns that the situation is worse than the authorities believed.”
According to the report, “Nuclear expert John Large* told Channel 4 News that any evidence of fission was a ‘concern’.”
“It shows there are still considerable problems. It’s concerning because it shows they are not in total control of the nuclear processes in the plant – and even a small amount of fission is a concern because it can become a large amount of fission,” said Large.
*Large was invited by the UK gov’t to join the Technical Advisory Panel working on assessing the implications of Fukushima for the country’s nuclear industry.
