Robert Alvarez - Why Fukushima Is a Greater Disaster than Chernobyl and a Warning Sign for the U.S.
April 25, 2012 In the aftermath of the world’s worst nuclear power disaster, the news media is just beginning to grasp that the dangers to Japan and the rest of the world posed by the Fukushima-Dai-Ichi site are far from over. After repeated warnings by former senior Japanese officials, nuclear experts, and now a U.S. Senator, it is sinking in that the irradiated nuclear fuel stored in spent fuel pools amidst the reactor ruins may have far greater potential offsite consequences than the molten cores
After visiting the site recently, Senator Ron Wyden (D-OR) wrote to Japan's ambassador to the U.S. stating that, "loss of containment in any of these pools could result in an even greater release than the initial accident."
This is why:
- Each pool contains irradiated fuel from several years of operation, making for an extremely large radioactive inventory without a strong containment structure that encloses the reactor cores;
- Several pools are now completely open to the atmosphere because the reactor buildings were demolished by explosions; they are about 100 feet above ground and could possibly topple or collapse from structural damage coupled with another powerful earthquake;
- The loss of water exposing the spent fuel will result in overheating can cause melting and ignite its zirconium metal cladding – resulting in a fire that could deposit large amounts of radioactive materials over hundreds of miles.
