The Olkiluoto 3 (OL3) nuclear power plant is one of the largest industrial projects in Northern Europe.
The construction of OL3 is a turnkey delivery by the French and German consortium formed by AREVA NP and Siemens. OL3 is a European pressurized water reactor plant, which is a new-generation pressurized water plant, built as first of a kind.
This cutting edge technology is the result of years of knowledge and experience gained from the operation of the latest reactors in Europe. The development of OL3 is based on plants commissioned in France (N4) and Germany (Konvoi). The main emphasis of basic design work has been placed on further development of safety, particularly the prevention and management of severe accidents
