More water leaks detected at Fukushima No. 1

JIJI

Tokyo Electric Power Co. said Tuesday it has detected leaks of radioactive water from two more storage tank areas at the Fukushima No. 1 nuclear plant.

Water levels have dropped inside walled areas in which storage tanks for radioactive water are located, indicating that up to 225 tons of tainted water may have seeped into the ground, Tepco officials said.

The two areas are located to the west of the No. 4 reactor building.

Water samples collected Friday contained 20 becquerels of strontium-90 per liter in one of the two areas and 440 becquerels in the other, higher than Tepco’s provisional limit of less than 10 becquerels for water that can be released from storage tank areas.

The news came after Tepco reported radioactive water leaks from two other tank areas over the weekend.
