The Fukui District Court's ruling this week that it will not allow the restart of two nuclear power reactors run by Kansai Electric Power Co. challenges the Abe administration's energy policy of keeping nuclear power as a key source of the nation's electricity supply despite the safety risks that materialized in the wake of the Fukushima nuclear power plant disaster in March 2011.

The court's Wednesday ruling was on a lawsuit filed by a group of 189 people from Tokyo, Fukui and other prefectures against the 2012 restart of two of the reactors at Kepco's Oi Nuclear Power Plant in Oi, Fukui Prefecture.

The two Oi reactors — the first to have been reactivated after all of the nation's nuclear reactors were shut down following the triple meltdowns at Tokyo Electric Power Co.'s Fukushima No. 1 plant — were taken offline last year for regular maintenance, leaving the nation again without nuclear power.
