Radioactive leaks reported from nuke plant in Japan's Ibaraki Prefecture

October 27, 2011 - Tokyo

Water containing radioactive material has reportedly leaked from a pressure vessel inside a reactor at a nuclear power plant in Japan's Ibaraki Prefecture.

According to the government's Nuclear and Industrial Safety Agency, the Tokai No. 2 nuclear power plant, which is operated by Japan Atomic Power Co. and located just north of Tokyo, might have lost around 64 tons of water from its pressure vessel. The water escaped into an outer container housing its boiling water reactor.

The plant's operator said workers mistakenly loosened a screw on the lower side of the vessel, which led to the water leaking and dousing four workers, Xinhua reports.

The Japan Atomic Power Co. said none of their workers had tested positive for internal radiation.

The operator said that an alarm sounded at the plant at 10:20 a.m. local time and workers arrived at the vessel to find water leaking from a pipe.

The Japan Atomic Power Co. said nuclear fuel, which can usually be found inside the pressure vessel, had been moved to a spent fuel pool due to the reactor being checked, and currently confirmed water levels in the pool have been maintained.
