Japan is preparing to restart the world’s largest nuclear power plant after a long hiatus. Authorities announced that one reactor at the Kashiwazaki-Kariwa Nuclear Power Plant will be reactivated next week. At a press conference on Friday, Take-yuki Inagaki, head of the plant operated by Tokyo Electric Power Company (TEPCO), said the reactor is scheduled to start on February 9.

The restart process had been temporarily halted earlier due to an alarm-related fault. Inagaki explained that the issue was linked to alarm settings and did not affect the plant’s operational safety. Last month, an attempt to restart a reactor at the Niigata Prefecture facility was also stopped within hours of initiation.

The Kashiwazaki-Kariwa plant has remained closed since Japan suspended nuclear power generation nationwide following the 2011 earthquake and tsunami, which caused reactor meltdowns at the Fukushima nuclear plant.
