We are most fortunate that the mysterious source of neutrons at Fukushima has just been found.
The risk to workers might be greater than previously thought because melted fuel in the No. 1 reactor building may be causing isolated, uncontrolled nuclear chain reactions, Denis Flory, nuclear safety director for the International Atomic Energy Agency, said at a press conference in Vienna.
Radioactive chlorine found March 25 in the Unit 1 turbine building suggests chain reactions continued after the reactor shut down, physicist Ferenc Dalnoki-Veress of the James Martin Center for Nonproliferation Studies in Monterey, California, wrote in a March 28 paper. Radioactive chlorine has a half-life of 37 minutes, according to the report.
Iodine 134 with a half life of under an hour gave me the same indication when I first discussed it on Sunday the 27th. Of course the neutrons I discussed on the 23rd of March were a dead giveaway despite the lame excuse given. Based on the time frame given in the link they knew no later than the 16th and possibly as early as the 13th that they had a recriticality problem. What was the point of trying to keep the secret for two weeks? The last half of this post may have the answer.
