Tokyo: Radioactive water is dripping out one of the newly installed steel above-ground tanks at the crippled Fukushima No. 1 nuclear plant, Tokyo Electric Power Co. has said.
Tepco said only about one liter of water has been leaked and poses no serious impact on the environment, adding the utility is investigating to determine the cause of the leak.
According to Japan Times, the tank was installed on the south side of the plant in May so Tepco could transfer part of the more than 20,000 tons of radioactive water held in the trench-like, triple-lined reservoirs.
Tepco said workers found radioactive water leaking from the surface of the steel tank at a rate of one drip per several seconds at 12:15 p.m. on Wednesday.
