Scheduled Maintenance Launched for Units 3 and 4 of Kursk Nuclear Power Plant

Starting August 11, 2026, Russia's Kursk Nuclear Power Plant launched scheduled routine maintenance on Units 3 and 4. On the same day, the plant also commenced annual maintenance and preventive upkeep of the heat network at the standby boiler house. The operations are scheduled to continue until August 22. Due to the maintenance schedule, hot water supply in the city of Kurchatov has been temporarily interrupted. The Kursk Nuclear Power Plant stated that this is the first time in nearly 50 years of plant operation that local hot water supply has been temporarily suspended due to related maintenance. Hot water supply to Kurchatov will be restored after the maintenance is completed. Alexey Leonov, Deputy Chief Engineer for Operations of the main building at Kursk NPP, said that the plant is currently undergoing significant changes, including the decommissioning of units that have reached their design service life and the commissioning of new units. These changes are transforming the ways thermal energy is produced and delivered to consumers, and also require modernization of the plant and related city infrastructure. He noted that this maintenance cycle is relatively short, and the schedule has been arranged to minimize impact on residents' daily lives. In recent years, the plant has taken measures to avoid scheduling maintenance on Units 3 and 4 during the winter season.
