Testifying before the Japanese House of Councilors, Mitsuhei Murata (Japan’s former ambassador to Switzerland) raised a disturbing threat: 85 times as much radioactive cesium-137 as was released at Chernobyl is at risk of being released into the atmosphere. This is not within a containment vessel, and the risk is fairly serious.
Japan, by the way, is down to just a single operating nuclear power plant from a high of 54–many of these shutdowns a result of the accident at Fukushima that made nuclear power unacceptable.
And the US is still extending licenses on decrepit worn out old nukes, and trying for the first time in decades to build new ones. What kind of madness is this?
