Olkiluoto power plant

There are three operational nuclear power plant units at the Olkiluoto nuclear power plant area. The boiling-water type power plants Olkiluoto 1 and 2 both have an electrical output of 890 MW. Their operating licences are valid until the end of 2038.

The third unit is a pressurised-water type. Olkiluoto 3 power plant unit has a gross output of approximately 1,600 MW.  The licence is also valid until the end of 2038. The planned life of the plant unit is 60 years, but the future manner and experience of use as well as the maintenance work on the plant will affect its future technical and safe life span.

The area also includes temporary storage for spent fuel as well as a final disposal facility for low and intermediate level waste, which has been operational for over 20 years. Posiva Oy is constructing a final disposal facility for spent fuel, which will be close to the power plant area as a separate facility area.

Olkiluoto nuclear power plant is owned by Teollisuuden Voima Oyj.
