A nuclear reactor in Kagoshima Prefecture resumed operation Thursday, becoming the second unit to restart after the government tightened safety regulations following the 2011 triple reactor meltdowns at the Fukushima No. 1 complex.
Kyushu Electric Power Co. said it reactivated the No. 2 reactor at its Sendai complex, about two months after the No. 1 reactor at the two-reactor plant began operating under what Prime Minister Shinzo Abe's government calls "the world's toughest" safety rules.
The first restart in August ended a nearly two-year hiatus in the country's nuclear power generation.
