TOKYO Japan’s top nuclear regulator raised safety concerns Monday about hastily built storage tanks and their foundations after signs of more leaks of radiation-contaminated water at the Fukushima Dai-Ichi nuclear power plant.
The latest leak was found over the weekend at a connecting pipe. The plant’s operator, Tokyo Electric Power Co. said it suspects there may also have been leaks from three storage tanks, because high radioactivity was detected near them. The levels were not considered deadly.
Nuclear Regulation Authority Chairman Shunichi Tanaka told a Tokyo news conference that the small leak and possible other leaks have added to concerns about the plant’s stability.
