I visited the Olkiluoto Nuclear Power Plant twice last year, on February and again on August. On August I also had the chance to visit Onkalo – the future site for the final disposal of radioactive waste.

The Olkiluoto plant currently consists of two Boiling Water Reactors, but a third reactor has been under construction since 2005. Olkiluoto 3 is an AREVA-developed European Pressurised Reactor (EPR). The start of commercial operation was originally planned for 2010, but the project is delayed and as of April 2018, the estimate for start of regular production is May 2019. Olkiluoto 3 is set to become Finland’s largest nuclear unit and provide about 10 percent of the country’s power needs.

The Olkiluoto plant is located on Olkiluoto Island on the shore of the Gulf of Bothnia in western Finland. It is owned and operated by Teollisuuden Voima (TVO), a subsidiary of Pohjolan Voima.
