Kyushu Electric Power Co. suspended the operation of a second reactor at its Sendai nuclear plant Wednesday as it will miss the regulators' deadline to implement anti-terrorism measures, following a halt of the other unit at the complex in March.
The No. 2 reactor at the Sendai plant in Kagoshima Prefecture went offline in the afternoon ahead of the Thursday deadline for the completion of anti-terrorism steps.
The utility aims to bring the reactor back online on Jan. 26 next year after making the required changes to facilities and undertaking regular safety inspections.
