TOKYO (Kyodo) -- Around 10,000 tons of contaminated water have pooled in underground trenches around the Nos. 1 to 4 reactor buildings of the crippled Fukushima Daiichi nuclear power plant, according to the plant operator Tokyo Electric Power Company Holdings Inc.
Tokyo Electric has no immediate plan to remove the water in the trenches where cables run for the nuclear power complex devastated by the March 2011 earthquake and tsunami disaster.
