Radioactive water leaking into sea

RIKUZENTAKATA (Japan), Apr 2 (agencies): Japan's prime minister surveyed the damage in a town gutted by a massive tsunami, as officials said Saturday that highly radioactive water was leaking into the sea from the nuclear plant stricken by the disaster. The Fukushima Dai-ichi nuclear complex has been spewing radioactivity since March 11, when a magnitude-9.0 earthquake and ensuing wave knocked out power, disabling cooling systems and allowing radiation to seep out of the overheating reactors. Saturday's leak was from a newly discovered crack in a maintenance pit on the edge of the Fukushima complex, Nuclear and Industrial Safety Agency spokesman Hidehiko Nishiyama said. The crack was apparently caused by the quake and may have been leaking since then, said spokesman Osamu Yokokura of Tokyo Electric Power Co., which runs the plant. Measurements showed the air above the radioactive water in the pit contained more than 1,000 millisieverts per hour of radioactivity. Even just two feet (60 centimeters) away, that figure dropped to 400 millisieverts. Workers have taken samples of the water in the pit and seawater and are analyzing them to determine the level of contamination. Radiation quickly disperses in both air and water, and experts have said that it would be quickly diluted by the vast Pacific Ocean, where even large amounts have little effect. TEPCO is trying to pour concrete to seal the 8-inch-long (20-centimeter-long) crack, spokesman Takashi Kurita said. Prime Minister Naoto Kan went to the plant and flew over the tsunami-damaged coast soon after the wave hit, but Saturday was the first time he set foot in one of the pulverized towns. Dressed in the blue work clothes that have become almost a uniform for officials, Kan stopped in Rikuzentakata, where the town hall is one of the few buildings still standing. All its windows are blown out and a tangle of metal and other debris is piled in front of it. The prime minister bowed his head for a minute of silence in front of the building. He met with the town's mayor, whose 38-year-old wife was swept away in the wave and is still missing. Officials fear about 25,000 people may have been killed, many of whose bodies have not been found. It wasn't immediately clear whether workers who have been rushing to bring the reactors under control were exposed. People living within 12 miles (20 kilometers) of the plant have been evacuated, and no fishing is taking place in the waters just off the plant. Because of the evacuations, the plant workers have been the primary people exposed to the radiation leaks. One crew member described difficult conditions inside the complex in an interview published Saturday. The worker also said the tsunami littered the grounds with dead fish that remained scattered throughout the plant, attracting birds. Radiation concerns have rattled the Japanese public, already struggling to return to normal life after the earthquake-generated tsunami. Three weeks later, more than 165,000 people are living in shelters, while 260,000 households still do not have running water and 170,000 do not have electricity. Thousands of families are also still awaiting news of their loved ones. More than 15,500 people are still missing. U.S. and Japanese troops launched an all-out search of the coastline Friday for any remaining bodies in what could be their last chance to find those swept out to sea. They have found nearly 50 bodies since Friday, most floating in coastal waters. So far, 11,800 deaths have been confirmed. Up and down the coast, helicopters, planes and boats carrying U.S. and Japanese troops scoured for the dead again Saturday. Some bodies may have sunk and just now be resurfacing. Others may never be found. As emergency crews rushed to cement the crack, the Tokyo Electric Power Co. (TEPCO) said it is also preparing to take samples from the ocean near the Fukushima nuclear plant to determine the level of contamination.
