In Japan, efforts to seal a crack leaking radioactive water into the sea at the Fukushima nuclear plant failed to yield any result. On Sunday workers injected water absorbent known as “water gel bag”, which contains polymeric materials used in diapers that can soak up 50 times its volume in their bid to block the leakage but the water flow remained unaffected. Japan's nuclear safety agency said, the efforts are aimed at blocking the 20-centimetre crack that has been found in a pit through which highly radioactive water is seeping into the Pacific Ocean. Japanese Chief Cabinet Secretary Yukio Edano said that it may take several months to bring under control the situation at the quake-hit facility. Meanwhile, Tokyo Electric Power Company, which operates the plant, said, two of its workers, who has been missing since the March 11 quake and tsunami, were found dead in the basement of a reactor's building.
