Tokyo Electric Power Co., facing more problems at the Fukushima No. 1 nuclear power plant than it originally thought, announced Tuesday a revised road map for bringing the crisis under control.
A major change from the first plan released a month ago will be using a massive amount of irradiated water flooding the basements of the turbine buildings for reactors 1, 2 and 3 as a main circulating coolant.
The original plan called for flooding the containment vessels to cool the reactor cores, but the level of the water in reactor 1's containment vessel doesn't appear to be increasing despite an injection of more than 10,000 tons of water.
