FUKUOKA – Kyushu Electric Power Co. said Wednesday it has decided to scrap its aging No. 2 reactor at its Genkai nuclear plant in Saga Prefecture.
The utility abandoned a plan to restart the unit, which has an output of 559 megawatts, in the face of the huge costs involved in enhancing the safety of the reactor that is already near the end of its 40-year operating life.
The reactor, which started operating in March 1981, has been idled since a routine checkup shortly before the March 2011 earthquake and tsunami disaster that triggered the Fukushima nuclear crisis.
The Genkai plant consists of four units. The utility already decided in 2015 to scrap its aging No. 1 unit, which had the same output capacity as the No. 2 reactor. Decommissioning work at the No. 1 reactor started in July 2017 and is expected to continue through fiscal 2043.
There have been a number of operational problems at the Genkai power plant. In May last year, pumps installed to control the circulation of cooling water at the No. 4 unit suffered malfunctions, following a steam leak from a pipe at the No. 3 reactor just a week after it was reactivated in March.
Some local residents have sought to stop operation of the Nos. 3 and 4 units with a temporary injunction, with doubts about the safety measures taken and citing the risk of volcanic eruptions in the region. Their case is pending at the Fukuoka High Court.
