The government will continue efforts to prevent atomic disasters by learning from last year's fatal nuclear accident in Tokai, Ibaraki Prefecture, Chief Cabinet Secretary Hidenao Nakagawa said Friday.

"We will make efforts to take steps to prevent nuclear accidents and respond to local residents' worries over their health," the top government spokesman said at a news conference ahead of the first anniversary today of the deadly accident.

The fission chain reaction at a uranium processing plant operated by JCO Co. in Tokai was Japan's worst nuclear accident.
