Highly contaminated water overflows into Pacific Ocean in second leak in two months at Daiichi site
[…]
The latest leaks show Tepco’s efforts to improve its handling of the contaminated water are not sufficient, Japan’s top government spokesman, Yoshihide Suga, told reporters on Thursday. The government will take steps to deal with the water, he said, adding that he thought the situation was under control.
Tepco has been relying on hastily built tanks to hold excess cooling water flushed over damaged reactors at the Fukushima Daiichi site, where three units suffered nuclear meltdowns and hydrogen explosions after a March 2011 earthquake and tsunami.
Tepco said the water that leaked contained 200,000 becquerels per litre of beta-emitting radioactive isotopes, including strontium 90. The legal limit for strontium 90 is 30 becquerels per litre.
The breach was discovered in a tank holding area away from where 300 tonnes of toxic water escaped in August.
About 430 litres (113 gallons) of water spilled over a period of as much as 12 hours after a worker misjudged how much could be held by the tank, which is tilting because of an uneven location, Tepco spokesman Masayuki Ono said.
The company is filling tanks to the brim as it does not have the capacity to accommodate the buildup of contaminated water, Ono said, adding that the water is likely to have flowed into a trench leading to the Pacific Ocean, about 300m (330 yards) from the tank.
