Highly radioactive water has been found in the basement of a building at the Fukushima Daiichi nuclear power plant near the storage facility for contaminated water.
Tokyo Electric Power Company said on Monday that it discovered about 700 tons of contaminated water on Saturday in the basement of an on-site building.
The utility said the water contained 19,000 becquerels of radioactive cesium 134 per cubic centimeter, and 22,000 becquerels of cesium 137 --- both very high levels.
Until June, the building was connected by a hose with another building where highly radioactive water is now being stored. The buildings are located next to each other and are part of the plant's waste disposal facility.
The utility is investigating how the leak happened. But it says it that there is no danger of the contaminated water leaking out of the building.
