TOKYO — Engineers pinned their hopes on chemicals, sawdust and shredded newspaper to stop highly radioactive water pouring into the ocean from Japan's tsunami-ravaged nuclear plant Sunday as officials said it will take several months to bring the crisis under control, the first time they have provided a timetable.
Concrete already failed to stop the tainted water spewing from a crack in a maintenance pit, and the new mixture did not appear to be working either, but engineers said they were not abandoning it.
The Fukushima Da-ichi plant has been leaking radioactivity since the March 11 tsunami carved a path of destruction along Japan's northeastern coast, killing as many as 25,000 people and knocking out key cooling systems that kept it from overheating.
The government said Sunday it will be several months before the radiation stops and permanent cooling systems are restored. Even after that happens, there will be years of work ahead to clean up the area around the complex and figure out what to do with it. 'It would take a few months until we finally get things under control and have a better idea about the future,' Nuclear and Industrial Safety Agency spokesman Hidehiko Nishiyama said.
His agency said the timetable is based on the first step, pumping radioactive water into tanks, being completed quickly and the second, restoring cooling systems, being done within a matter of weeks or months.
Every day brings some new problem at the plant, where workers have often been forced to retreat from repair efforts because of high radiation levels. On Sunday, plant operator Tokyo Electric Power Co. announced it had found the bodies of two workers missing since the tsunami.
Radiation, debris and explosions kept workers from finding them until Wednesday, and then the announcement was delayed several days out of respect for their families. TEPCO officials said they thought the workers ran down to a basement to check equipment after the magnitude-9.0 earthquake that preceded the tsunami. They were there when the massive wave swept over the plant.
