Summary

Climate change is expected to modify sea temperature, snow and ice accumulation and frazil ice formations, which might affect the air and water intakes of nuclear power plants (NPP) in colder regions. Direct impacts include loss of production due to partial or full outages, loss of efficiency due to higher cooling water temperature, and rising costs of repairs, refurbishment, and safety upgrades. Teollisuuden Voima Oyj (TVO), an energy company based in Finland, proposed several actions to reduce these impacts. For instance, at the Olkiluoto NPP, adaptation measures consist of preventing blockage by snow of air intakes and of heating of air intakes. At the Loviisa NPP, such measures include construction of an air-cooling system to supplement sea cooling in case of frazil ice formation, and heating water intake grids to prevent frazil ice formation.
