Summary More leaks have triggered further concerns about the plant's ability to manage contaminated water.
TOKYO (AP) Japan s top nuclear regulator has raised safety concerns about hastily built storage tanks and their foundations amid reports of new leaks of radiation-contaminated water.
Nuclear Regulation Authority Chairman Shunichi Tanaka said Monday that a small leak and signs of possible leaks have been spotted at several other Fukushima Dai-ichi storage tanks. Officials say part of the leak has escaped into the sea.
He said the discoveries were the result of closer inspections after a 300-ton leak two weeks ago. Tanaka raised concerns about the tanks foundations and urged careful monitoring.
The plant s operator says it suspects other possible leaks because radioactivity has been detected near the tanks, although it is not considered deadly.
More leaks have triggered further concerns about the plant s ability to manage contaminated water.
