Spent reactor fuel, containing roughly 85 times more long-lived radioactivity than released at Chernobyl, still sits in pools vulnerable to earthquakes.
More than a year after the Fukushima nuclear power disaster began, the news media is just beginning to grasp that the dangers to Japan and the rest of the world are far from over. After repeated warnings by former senior Japanese officials, nuclear experts, and now a U.S. senator, it’s sinking in that the irradiated nuclear fuel stored in spent fuel pools amidst the reactor ruins pose far greater dangers than the molten cores. This is why:
â€¢ Nearly all of the 10,893 spent fuel assemblies sit in pools vulnerable to future earthquakes, with roughly 85 times more long-lived radioactivity than released at Chernobyl
â€¢ Several pools are 100 feet above the ground and are completely open to the atmosphere because the reactor buildings were demolished by explosions. The pools could possibly topple or collapse from structural damage coupled with another powerful earthquake.
