The governor of Niigata Prefecture, which is home to the world’s largest nuclear power plant, is set to give the approval this week for the plant’s restart, according to informed sources.

The approval will clear the final hurdle in Tokyo Electric Power Company’s (Tepco) quest to bring the Kashiwazaki-Kariwa plant back online, more than a decade after the Fukushima nuclear disaster led to its shutdown.

Niigata Gov. Hideyo Hanazumi is set to announce his approval as early as Friday to partially resume Kashiwazaki-Kariwa, the sources said.
