I am listening to an on-line broadcast of an interview with a Prof. Koide of Kyoto U. He says the latest indications are that the reactor vessel is not holding water. Therefore it must have "a fairly large hole" in the bottom.
Yikes! The TMI reactor walls were eroded by hot "rubbleized" reactor core, but there was no hole all the way through. Needless to say, this was the lead story on NHK yesterday. They talked about TMI, and showed videos of the people opening for the first time, and videos of the inside. - Jed
