Scientific American 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. "The hydrogen accumulates outside of containment but inside the reactor building. The 3.7-meter-long nuclear fuel used at Fukushima is composed of uranium oxide pellets encased in a zirconium cladding. The high temperatures that the fuel rods create boil water and continually turn it into steam. Already, radiation at undisclosed levels and in undisclosed forms has been detected on the U.S.S.
