Japanese utility Chugoku Electric Power plans to shut its 820MW Shimane No.2 nuclear reactor from February-August to carry out maintenance works.
Chugoku will close the No.2 reactor at Shimane in western Japan on 9 February, the company said on 8 January. Test generation is expected to resume on 6 August in the final phase of the turnaround, according to a power plant operational status notice by the Japan Electric Power Exchange. Full maintenance completion is targeted for 4 September.
This will be the first maintenance check for the Shimane reactor since it returned to service in December 2024 after nearly 13 years off line for enhanced nuclear safety inspections following the 2011 Fukushima disaster.
The Shimane No.2 reactor is Chugoku's sole nuclear unit in operation. The shutdown would require the utility to boost replacement thermal generation units to meet peak demand in the remainder of winter and in early summer.
Chugoku consumed 2.72mn t of coal in April-September 2025, up by 16pc from the same period a year earlier, while its oil use rose by 25pc to 1,719 b/d. But LNG consumption fell by 11pc to 500,000t during the period.
