This is one of four nuclear power plants in Japan now in trouble, after a devastating 9.0 earthquake and subsequent tsunami.)

Kyodo News service, Japan: "The Fire and Disaster Management Agency said a cooling system pump stopped operating at Tokai No. 2 Power Station, a nuclear power plant, in the village of Tokai, Ibaraki Prefecture."

Related: Japan's nuclear safety agency says the Onagawa plant that reported higher than normal radioactivity levels is said to be "functioning properly." The increased levels are believed to have been caused by leakage at nearby Fukushima.
