Hot Air has a very helpful series of updates on the nuclear crisis in Japan, and the Washington Post has an excellent series of graphics explaining, among other things, the design of the Japanese reactors and how the failures have occurred. It makes sense out of the welter of information, some of it contradictory, coming out of Japan.
Right now the situation is much worse than the Three Mile Island accident (which had no perceptible effect on anything outside the plant itself) and heading for a calamity of the proportions of the Chernobyl disaster of 1986.
