# 1702: The Japan Atomic Power Company has said the cooling system of a reactor at its Tokai nuclear power plant is working, although two of the three diesel power generators used for cooling are out of order, the Reuters news agency reports. The plant, about 120km (75 miles) north of Tokyo in Ibaraki prefecture, was automatically shut down after Friday's earthquake.
# 1706: The news about Tokai comes as the authorities battle to prevent a meltdown at the stricken Fukushima-Daiichi complex. Sea water is being pumped into three overheating reactors there. The plant was rocked by an explosion on Saturday, which blew off the roof of one reactor building. Meanwhile, a state of emergency has been declared at a second nuclear site. The International Atomic Energy Agency said increased levels of radiation had been detected at Onagawa, close to the area worst hit by the tsunami.
