TOKYO — The difficult task of pumping highly radioactive water out of the basement of a turbine building at a damaged Japanese nuclear power plant began yesterday, but officials cautioned that the work would be slow and difficult.
The Tokyo Electric Power Co. said that it planned to pump 10,000 metric tons of water into a storage building at a rate of 480 tons a day, which would take nearly three weeks. The company is still working on ways to remove an additional 57,500 tons of highly contaminated water at the same building, Unit 2, and at other nearby buildings.
