en.Wedoany.com Reported - The Swiss Federal Nuclear Safety Inspectorate (ENSI) has approved the restart of the Gösgen Nuclear Power Plant after the completion of its 2026 annual maintenance, with the restart scheduled for June 26, 2026.

The Gösgen Nuclear Power Plant was shut down as planned on May 30, 2026, entering an approximately four-week annual maintenance period. During the maintenance, ENSI monitored and supervised the relevant work and conducted inspections and checks. The Swiss Association for Technical Inspections (SVTI) continued to support ENSI experts this year.

This major overhaul primarily involved routine inspections and maintenance of multiple systems and components, including a pressure test of the reactor circuit and testing of one of the three low-pressure turbines in the non-nuclear island section. No modifications were made to the reactor core during this outage. Due to the short operating period since March 2026, no fuel assemblies were replaced during this maintenance cycle.

ENSI confirmed that the Gösgen Nuclear Power Plant has completed its 2026 annual maintenance in accordance with relevant regulations and complied with radiation protection requirements. The authority considers that the plant has met the statutory conditions for resuming power generation and has therefore approved its restart.
