Tokyo Electric Power Co. says it found that about 10 liters of water containing radioactive strontium leaked from a water processing facility at the Fukushima No. 1 nuclear plant but it did not flow into the Pacific Ocean.
The Nuclear and Industrial Safety Agency ordered Tepco on Tuesday to take measures to prevent a recurrence and consider moving up the schedule for installing a facility for removing radioactive substances such as strontium from water, a difficult process for the existing facility.
Tepco said earlier it plans to install the “multi-nuclide removal facility” sometime in 2012.
Liquid was found at around 10:30 a.m. Tuesday dripping from a tank storing salt water, which is created in the process of decontaminating highly polluted water accumulating at the plant, according to Tepco and NISA officials. The water leaked after undergoing a process for removing radioactive cesium.
The leak was stopped after workers tightened a bolt around the area where the leak occurred, the officials said.
The facility is essential in the process of injecting water into the plant’s three crippled reactors to keep them cool.
No more insurance
Tokyo Electric Power Co. will deposit ¥120 billion with the central government in place of insurance coverage after failing to extend its contract covering the Fukushima No. 1 nuclear plant, according to sources.
Tepco has been seeking, so far unsuccessfully, to reach an agreement with a foreign insurer.
