NBC NEWS – A plant worker found the leak Wednesday morning during valve checks at a SARRY treatment machine designed to remove cesium from the contaminated water, the Tokyo Electric Power Company (Tepco) said. The machine has been idled for maintenance work. An estimated 6 tons of radioactive water — enough to fill two ordinary backyard swimming pools — leaked out through an air vent, leaving a pool of water on an iron plate outside and seeping into the soil around it, Tepco said, but no radioactive water escaped the compound. It is not clear when the machine began leaking, but Tepco said that no problems were detected in an inspection Tuesday.
