Mapping of Condition Monitoring Systems in Olkiluoto Nuclear Powerplants

When building a new nuclear power plant condition monitoring systems is a natural and integrated part of the design to facilitate monitoring of both large singular key components and small basic components used by the dozen. Installing condition monitoring systems in existing nuclear power plants is also possible, it just takes more effort to adapt the installation to the preconditions in the plant.

In this project, the condition monitoring systems of the Olkiluoto nuclear plant have been mapped. The plant has two older units commissioned in 1979/1982 and one new plant that is scheduled for regular operation starting 2022. The condition monitoring in Olkiluoto is at advanced level and the overall understanding of the plant units’ condition is high quality due to high level of expertise and wide range of condition monitoring systems and methods used.
