Kansai Electric Power Co. on Wednesday restarted a reactor at its Oi plant on the Sea of Japan coast, located close to two other units already online, amid lingering safety concerns following the 2011 Fukushima disaster.
It is the first time that multiple nuclear reactors in the same area have been in operation since the crisis at the Fukushima No. 1 plant, triggered by the March 2011 earthquake and tsunami.
