TVO (Teollisuuden Voima Oyj) has today decided to commence the bidding and engineering phase of the company's fourth nuclear unit at Olkiluoto, Finland.
TVO said it expected the cost of the phase to be up to 300 million euros.
The target of the bidding and engineering phase is to select a plant unit that meets all the latest safety requirements.
Last month, GE Hitachi Nuclear Energy (GEH) announced it has signed a project development memorandum of understanding (MOU) with Fluor Corporation to pursue this project.
According to the decision-in-principle, ratified by the Finnish Parliament in July 2010, the application for a building permit for the Olkiluoto's fourth unit must be filed latest in June 2015.
