Yikes. I’m with the Japanese who think that this situation is far more dire than officials have been letting on.

Tokyo Electric Power said Tuesday that after the explosion at the No. 2 reactor pressure had dropped in the “suppression pool” — a section at the bottom of the reactor that converts steam to water and is part of the critical function of keeping the nuclear fuel protected. After that occurred radiation levels outside No. 2 were reported to have risen sharply.

“We are on the brink,” said Hiroaki Koide, a senior reactor engineering specialist at the Research Reactor Institute of Kyoto University. “We are now facing the worst-case scenario. We can assume that the containment vessel at Reactor No. 2 is already breached. If there is heavy melting inside the reactor, large amounts of radiation will most definitely be released.”
