Japanese regulator urges Tepco to find source of radioactive leak.

FT: “Japan’s nuclear regulator says radioactive water from the crippled Fukushima power plant is probably leaking into the Pacific Ocean, a problem long suspected by experts but denied by the plant’s operator.” “Officials from the Nuclear Regulation Authority said a leak was “strongly suspected’’ and urged plant operator Tokyo Electric Power Co to determine where the water may be leaking from and assess the environmental and other risks, including the impact on the food chain. The watchdog said on Wednesday it would form a panel of experts to look into ways to contain the problem.
The watchdog’s findings underscore Tepco’s delayed response in dealing with a problem that experts have long said existed. On Wednesday, the company continued to raise doubts about whether a leak exists.
