Annual outage maintenance of Loviisa Nuclear Power Plant begins on August 2

Fortum, the Finnish state-owned energy company, announced that the annual outage maintenance of the Loviisa Nuclear Power Plant will commence on August 2, starting with Unit 2 and then transitioning to Unit 1. The maintenance is scheduled to continue until October 18. During this period, the two units will be taken offline for maintenance in rotation, with the other unit remaining in operation. As planned, Unit 2 will undergo a major annual overhaul conducted every eight years. During the maintenance, staff will unload the reactor fuel, inspect and pressure test the reactor pressure vessel, replace approximately one-quarter of the fuel, and complete a series of equipment maintenance and servicing tasks. Unit 1 will undergo a shorter routine annual maintenance, primarily involving fuel replacement and related maintenance work.
