This (from Scientific American)I thought was a pretty good round up on the situation with the reactors. Especially I now understand the explosions and why they are happening. Apparently the great heat eventually strips hydrogen from water and as that builds up an explosion is possible. Interestingly nothing is said if the stripping of the hydrogen also provides Oxygen, but it would have to would it not? If anyone knows please comment.
Just after 6 AM local time on Tuesday in Japan, a sound like an explosion was heard near the suppression pool of reactor No. 2 at the stricken Fukushima Daiichi nuclear power plant. This followed an explosion March 11 that ripped the roof off reactor No. 1 and another at reactor No. 3 on March 14 that injured 11 workers. The culprit in all three cases is likely a build-up of explosive hydrogen gas–as occurred at Three Mile Island in the U.S. in 1979 as a result of the meltdown there–caused by nuclear fuel rods experiencing extremely high temperatures stripping the hydrogen out of the plant’s steam.
