Radioactive water leaks from Tepco plant

Tonnes of radioactive water was discovered to have leaked into the ground from the Fukushima nuclear plant, Japan's nuclear watchdog said on Tuesday.
About 15 tonnes of water with a low level of radiation leaked from a storage tank at the plant, on the Pacific coast 240 km (150 miles) north of Tokyo, the Nuclear and Industrial Safety Agency said.
Plant operator Tokyo Electric Power Co said it was still investigating the cause of the leak, which was repaired
after being discovered around noon on Tuesday.
Vast amounts of water contaminated with varying levels of radiation have accumulated in storage tanks at the plant after being used by the utility to cool reactors damaged when their original cooling systems were knocked out by the March 11 earthquake and tsunami.
Tepco is trying to use a decontamination system that cleans radioactive water so it can be recycled to cool the reactors, but has encountered technical glitches.
