TEPCO to decommission Kashiwazaki-Kariwa reactor

It presented a basic approach related to decommissioning Units 1-5.

Tokyo Electric Power Co. (TEPCO) expects to decommission one or more of Kashiwazaki Kariwa Nuclear Power Plants Units 1 to 5 in five years after restarting Units 6 and 7, according to Japan Atomic Industrial Forum.

TEPCO presented to Kashiwazaki City mayor Masahiro Sakurai a document laying down its basic approach to the recommencement of operation as well as the decommissioning of the power plants.

On June 2017, Sakurai requested the power company to present a decommissioning plan for Units 1 to 5 by 2019, as condition for approving the restarts of Units 6 and 7.

The document also outlined its aim for "future desired power-source composition," in fulfillment of the fifth national Strategic Energy Plan's target of having 40% of total generated electricity come from non-fossil fuel sources by 2030.

TEPCO is aiming to develop 2-3 MW of renewable energy power generations in the coming decade whilst making maximum use of its NPPs.

Meanwhile, safety measures at Unit 7 are expected to be completed by December 2020.
