IAEA COMMENTS AT PRESS CONFERENCE IN VIENNA

IAEA HAS NO INFORMATION FROM TEPCO ON NEUTRON DETECTORS
If indeed the reactor has gone critical again, the whole concrete dome idea may have to be promptly scrapped.

The Automatic Earth's senior editor Stoneleigh is a nuclear safety expert. The subject of her master thesis at the Law Faculty of Warwick University in Coventry, England, was nuclear safety research.
After graduating in 1997, she became a Research Fellow at the Oxford Institute for Energy Studies, where her research field was power systems, with a specific focus on nuclear safety in Eastern Europe.
The monograph she wrote sets the nuclear safety debate in the political and economic context of the collapse of the Soviet Union. It was published in 1999 under the title Nuclear Safety and International Governance: Russia and Eastern Europe, and it remains available online here at the Oxford Institute for Energy Studies.
“Tokyo Electric Power Co. said Wednesday it is considering spraying boric acid by helicopter to prevent spent nuclear fuel rods from reaching criticality again, restarting a chain reaction, at the troubled No. 4 reactor of its quake-hit Fukushima No. 1 nuclear power plant. "The possibility of recriticality is not zero," TEPCO said as it announced the envisaged step against a possible fall in water levels in a pool storing the rods that would leave them exposed”
Stonleigh says: “It looks like to cut costs TEPCO placed the spent fuel rods too close to each other. ReCriticality = massive explosion.”
The situation at Japan's Fukushima Daiichi nuclear power plant has become extremely unnerving. The Tokyo Electric Power Company has now admitted that the spent fuel rods could go critical - that is, a nuclear chain reaction could restart.
