Japan Finds Radioactive Water Leaking into Ocean VOA News April 02, 2011 Workers collect data in the control room for Unit 1 and Unit 2 at the tsunami-crippled Fukushima Dai-ichi nuclear power plant Photo: AP Photo/Nuclear and Industrial Safety Agency In this photo released by Nuclear and Industrial Safety Agency, Tokyo Electric Power Co. workers collect data in the control room for Unit 1 and Unit 2 at the tsunami-crippled Fukushima Dai-ichi nuclear power plant, March 23, 2011. Nuclear safety officials say a newly-discovered crack in Japan's damaged nuclear plant could be the source of radioactive water that is leaking into the Pacific Ocean. Nuclear safety spokesman Hidehiko Nishiyama told reporters Saturday the water could be leaking from a crack in a maintenance pit on the edge of the Fukushima nuclear site. Nishiyama said the Tokyo Electric Power Company is planning to pour concrete into the pit to seal the crack. Earlier in the day, Japanese Prime Minister Naoto Kan visited the tsunami-devastated region, meeting workers in the nuclear exclusion zone and talking to residents made homeless by the March 11 disaster. At a school-turned evacuation center, Mr. Kan told evacuees that the government would support them until the end of the recovery process. The Japanese leader also visited a village just inside the exclusion zone which is serving as the headquarters for emergency teams trying to cool the six reactors at the plant. United Nations Secretary-General Ban Ki-moon said Friday that the situation at the plant "remains very serious." The U.N.'s atomic energy agency has warned that high concentrations of radioactive particles have spread outside the 30-kilometer exclusion zone around the nuclear plant. The agency reported Friday that in one village, Iitate, some 40 kilometers from the plant, radiation levels are decreasing after spiking at levels substantially above that at which they recommend evacuations. Japan's chief government spokesman Yukio Edano confirmed reports that the groundwater around the plant is contaminated with radiation many times higher than normal, and that testing on cattle had turned up a low-level sample of radioactive-contaminated beef. Thousands of Japanese and American military personnel joined together Friday in a final three-day sweep to search for those still missing from the March 11 earthquake and tsunami. More than 11,000 people are confirmed dead, with more than 16,500 still missing. But the search teams will stay out of the evacuation zone around the damaged plant.
