Reactors No. 4, 5, and 6 at Fukushima were shutdown when the earthquake struck. After the water drained and the spent fuel became exposed, the pool at reactor No. 4 caught fire, and continues to burn, as of Thursday March 17, releasing massive amounts of radiation into the environment. The status of the other six spent fuel pools at Fukushima is unknown. A courageous U.S. journalist Rachel Maddow explored the spent fuel pool issue with a former government official. The most important, critical point made by Princeton professor Frank Von Hippel occurs at minute 14:19 -- where Rachel Maddow talks over him: these are LONG-LIFE RADIONUCLIDES being emitted from the spent fuel pool(s). Isotopes of cesium: Cs-137 has a half-life of 30 years and will be around and hot for decades.
How much disaster are we talking about? The atomic bomb that exploded at Hiroshima created about 2000 curies of radioactivity. The spent fuel pools at Vermont Yankee Nuclear Plant (U.S.) are said to hold about 75 million curies. There are six spent fuel pools at Fukushima, but the numbers of tons of fuel rods in each have not been made public.
The Nuclear Information and Resource Service (NIRS) did the math: If Fukushima's Reactor No. 4 operated for 35 years and produced 30 tons of irradiated fuel per year and each ton is equivalent to 24 times the amount of cesium-137 produced by the Hiroshima bomb, then each fuel pool could contain on the order of 24,000 times the amount of cesium-137 produced by the Hiroshima bomb, if all the produced irradiated fuel remains in the fuel pool.
Nuclear stupidity No. 1: the Fukushima reactor buildings are square (not circular) and had to absorb the force of the tsunami wave straight on. Stupidity No. 2: six reactors clustered too close together. Stupidity No. 3: no shoreline protection against a tsunami. Stupidity No. 4: reactors sited on earthquake faults. Stupidity No. 5: assumptions and calculations proving that the reactor, prior to its construction, could withstand anything that nature threw at it. Stupidity No. 6: it didn't begin in Japan: the industry, with all its corruptions, false assumptions and technological hubris, was born in secrecy in the United States of America. More...
