Recently, former diplomats and experts both in Japan and abroad stressed the extremely risky condition of the Fukushima Daiichi Unit 4 spent nuclear fuel pool and this is being widely reported by world media. Robert Alvarez, Senior Scholar at the Institute for Policy Studies (IPS), who is one of the best-known experts on spent nuclear fuel, stated that in Unit 4 there is spent nuclear fuel which contains Cesium-137 (Cs-137) that is equivalent to 10 times the amount that was released at the time of the Chernobyl nuclear accident. Thus, if an earthquake or other event were to cause this pool to drain, this could result in a catastrophic radiological fire involving nearly 10 times the amount of Cs-137 released by the Chernobyl accident.
Nearly all of the 10,893 spent fuel assemblies at the Fukushima Daiichi plant sit in pools vulnerable to future earthquakes, with roughly 85 times... |
