FILE - In this Wednesday, May 11, 2011 photo released by Tokyo Electric Power Co. (TEPCO), workers look at a pit, center, which is being filled with concrete after they found another leak of radioactive water into the sea, near a seawater intake of the No. 3 reactor building at the tsunami-crippled Fukushima Dai-ichi nuclear power 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. 31, 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.
