The Olkiluoto Nuclear Power Plant is one of Finland’s two nuclear power plants, the other being the two-unit VVER Loviisa Nuclear Power Plant. The plant is owned and operated by Teollisuuden Voima (TVO), a subsidiary o Pohjolan Voima, and is located on Olkiuoto Island, on the shore of the Gulf of Bothnia, in the municipality of Eurajoki in western Finland.

The Olkiluoto plant consists of two boiling water reactors (BWRs), each producing 890 MW of electricity. A third reactor, Unit 3, is expected to be online in March 2021.

Unit 3 is an EPR reactor and has been under construction since 2005. The start of commercial operation was originally planned for May 2009 but the project has been delayed and, as of December 2019, the latest estimate for start of regular production is March 2021. In December 2012, the French multi-national building contractor, Areva, estimated that the full cost of building the reactor will be about €8.5 billion, or almost three times the delivery price of €3 billion.
Naurex has been invited to provide Technical Assistance support until the end of the project and in parallel works with Framatome Germany/Finland in order to evaluate the expected manpower requirements for when the Maintenance Contract starts. Besides the OL3 Project, Naurex is currently positioning itself for proposing Technical Assistance Services for  the Hanhikivi Project, equally in Finland.
