Chugoku Electric Power said Tuesday that the planned restart of the No. 2 reactor at its Shimane Nuclear Power Plant in western Japan will be delayed from August by about four months.

The delay stems from work to reinforce safety measures and a facility inspection at the plant in Matsue, the capital of Shimane Prefecture.

The company now aims to reactivate the 820,000-kilowatt reactor in December, aiming for a restart of commercial operations the following month.
