The No. 7 reactor at the Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture will be suspended early Tuesday for an 83-day scheduled checkup, its operator Tokyo Electric Power Co. said Monday.
Suspension of the reactor will bring to 14 the total number in operation among the nation’s 54 commercial reactors. It will leave only the No. 5 and No. 6 reactors operating at the plant, the biggest nuclear power complex in the world in terms of output power.
Tokyo Electric Power is required to undertake a newly introduced safety assessment procedure before restarting the reactor.
