More leaks of contaminated water at Fukushima

12 October 2016

Tokyo Electric Power Company (Tepco), operator of Japan’s Fukushima Daiichi NPP, confirmed on 7 October that radioactive water had again leaked from one of its storage tanks but said the contaminated water was contained. Technicians at the NPP detected the leak from a cylindrical steel tank on 5 October, Efe news reported. The leak was attributed to a problem with the tank's welding. Tepco calculated that around 32 litres of the water had spilled, with a contamination level of 590,000 Becquerel per litre. The water from the damaged tank was decanted into another to prevent further leakage. Tepco said tanks susceptible to spills are progressively replaced but as there are thousands of them, replacement within a short period has proved difficult.
