Fukushima: Government agency tells TEPCO to take steps to prevent radioactive water leaks - 6th Dec 2011

The government's Nuclear and Industrial Safety Agency (NISA) instructed Tokyo Electric Power Co. (TEPCO) on Dec. 5 to take measures, including installing leakage detectors, to prevent radioactive water from leaking from the crippled Fukushima No. Nuclear Power Plant after a massive amount of water containing radioactive substances was found spilling from a water processing facility there.

TEPCO, the operator of the troubled Fukushima nuclear power complex, failed to notice the water leakage for about 21 hours after it started operating the desalination facility, which had no leakage detectors, on the afternoon of Dec. 3. The government notified embassies in Japan of the mishap as there is a possibility of water containing radioactive substances flowing into the ocean.

According to the utility, the amount of leaked water inside a reactor building that houses the processing facility was about 45,000 liters, or 45 cubic meters. About 300 liters of water leaked outside the reactor building, and the water could have flowed into the ocean after leaking through a concrete crack in the building into a nearby gutter The water near a water outlet close to the ocean contained 18 becquerels of cesium per liter on Dec. 4 -- a level that is below the legal limit for releasing water into the ocean.
