"TOKYO -- A power plant operator in southern Japan restarted a nuclear reactor on Tuesday, the first to begin operating under new safety requirements following the Fukushima disaster.

Kyushu Electric Power Co. said Tuesday it had restarted the No. 1 reactor at its Sendai nuclear plant as planned. The restart marks Japan's return to nuclear energy four-and-half-years after the 2011 meltdowns at the Fukushima Dai-ichi nuclear power plant in northeastern Japan following an earthquake and tsunami.

The national broadcaster NHK showed plant workers in the control room as they turned the reactor back on. Tomomitsu Sakata, a spokesman for Kyushu Electric Power, said the reactor was put back online without any problems."
