Shimane Nuclear Power Station Unit 2 completes containment vessel-related repairs, scheduled to resume commercial operation on the 16th of next month

The Shimane Nuclear Power Station Unit 2, located in Matsue City, Japan, is scheduled to resume commercial operation next month. Recently, part of the reactor containment vessel repair work at the unit was opened to the public, showcasing key construction steps before the resumption of operation.

Unit 2 of the Shimane Nuclear Power Station resumed operation in December two years ago. Since February this year, the unit has been shut down for routine operational inspections. In accordance with relevant legal requirements, nuclear power units must undergo equipment disassembly inspections and replacement of related components within 13 months after the previous inspection is completed.

On August 3, a dedicated crane was used on site to lift a cover weighing approximately 60 tons to the top of the reactor containment vessel. Workers completed the tightening of 120 bolts that day, and the related repair work was finished the following day.

The unit was originally scheduled to resume commercial operation on the 4th of next month. Due to corrosion issues discovered in some equipment during inspections and subsequent maintenance work, the resumption of commercial operation has been adjusted to the 16th of next month.

The headquarters of the Shimane Nuclear Power Station of Chugoku Electric Power in Japan stated that it will continue to prioritize safety and diligently advance all work.
