FILE - In this March 21, 2011 file photo released by Tokyo Electric Power Co. (TEPCO), smoke rises from the Unit 3 reactor of the tsunami-damaged Fukushima Dai-ichi nuclear plant in Okuma town, Fukushima prefecture, northeastern Japan. The operator of a Japanese nuclear plant that went into a tsunami-triggered meltdown knew the risks from highly radioactive water at the site but sent in crews without adequate protection or warnings, a worker said in a legal complaint filed Tuesday, Oct. 30, 2012. Asked about the allegations, a TEPCO spokesman said the plant was aware of water leaks elsewhere but couldn't anticipate the water problem in Unit 3's basement.
