Now that is the worst case scenario:
As Robert Alvarez, a former nuclear energy adviser to President Bill Clinton, has written, if these waste containers, euphemistically called “ponds,” were to be damaged in an explosion and lose their cooling and radiation-shielding water, they could burst into flame from the resulting burning of the highly flammable zirconium cladding of the fuel rods, blasting perhaps three to nine times as much of these materials into the air as was released by the Chernobyl reactor disaster. (And that’s if just one reactor blows!)
Each pool, Alvarez says, generally contains five to ten times as much nuclear material as the reactors themselves. Alvarez cites a 1997 Nuclear Regulatory Commission study that predicted that a waste pool fire could render a 188-square-mile area “uninhabitable” and do $59 billion worth of damage (but that was 13 years ago).
You are still not told the truth people.
U.S. Calls Radiation ‘Extremely High’ and Urges Deeper Caution in Japan
– U.S. Calls Radiation ‘Extremely High’ and Urges Deeper Caution in Japan (New York Times):
WASHINGTON — The chairman of the United States Nuclear Regulatory Commission gave a significantly bleaker appraisal of the threat posed by Japan’s nuclear crisis than the Japanese government, saying on Wednesday that the damage at one crippled reactor was much more serious than Japanese officials had acknowledged and advising to Americans to evacuate a wider area around the plant than the perimeter established by Japan.
Gregory Jaczko, the chairman of the commission, said in Congressional testimony that the commission believed that all the water in the spent fuel pool at the No. 4 reactor of the Fukushima Daiichi Nuclear Power Station had boiled dry, leaving fuel rods stored there exposed and bleeding radiation. As a result, he said, “We believe that radiation levels are extremely high, which could possibly impact the ability to take corrective measures.”
If his analysis is accurate and Japanese workers have been unable to keep the spent fuel at that inoperative reactor properly cooled — it needs to remain covered with water at all times — radiation levels could make it difficult not only to fix the problem at reactor No. 4, but to keep workers at the Daiichi complex from servicing any of the other problem reactors at the plant.
