Both units at Fortum’s Loviisa nuclear power plant are back in production after completion of their annual outages. This year, both units underwent the short refuelling outage. The annual outage of Unit 2 was completed on 7.9.2023 and Unit 1 on 1.10.2023.
“In conjunction with the annual outage of Unit 1, a faulty seawater pump motor was replaced, and the servicing work on Unit 2’s second turbine line continued still after the annual outage,” says Sasu Valkamo, Senior Vice President of Loviisa nuclear power plant.
During the annual outages, about a quarter of the fuel in both plant units was replaced. In addition to the normal periodic maintenance work and refuelling, tasks related to maintenance and continuous improvement were carried out on both units during the annual outages.?
“This year, a test assembly manufactured by Westinghouse was loaded into the reactor; the test assembly doesn’t contain the actual nuclear uranium pellets. We are pursuing mechanical operating experiences with the new fuel type,” says Valkamo.
Fortum and Westinghouse Electric Company signed an agreement in November 2022 for the design and supply of a new fuel type for the Loviisa power plant.
