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 firm also took into account that it is unable to secure land to build a counterterrorism facility, which is required under Japan's new nuclear safety rules.
