Tokyo Electric Power Company Holdings Inc. said Monday it may decommission one or more reactors at its Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture within five years, after reactivating two idled reactors at the same plant.
Tepco President Tomoaki Kobayakawa mentioned for the first time the possibility of decommissioning some or all of the Nos. 1 to 5 reactors at the Kashiwazaki-Kariwa plant, the world's biggest nuclear plant by capacity.
The host city's Mayor Masahiro Sakurai has made such decommissioning a condition for approving the restarts of its Nos. 6 and 7 reactors.
