Mitsubishi Heavy Industries Ltd. (MHI) on March 26 said it received an order for an engineering study in Finland from Teollisuuden Voima Oyj (TVO) for Olkiluoto 4 (OL4), the utility's planned fourth nuclear power plant.
MHI said it will conduct a feasibility study aiming to secure and to fulfill engineering, procurement and construction requirements in the bid of the EU-APWR based on the TVO's inquiry of the OL4 plant. The EU-APWR is a 1,700 MWe class reactor. MHI developed the EU-APWR based on the previously developed 1,538 MWe APWR in Japan, with features modified to reflect European regulations and the requirements of EU customers. To ensure high level of safety and reliability, the reactor incorporates various advanced features such as four-train safety systems with advanced accumulators, and fully digitalized instrumentation and control equipment.
TVO has already reached the decision in principle from the Finnish government and parliament to construct OL4. TVO has been advancing the construction project towards submitting a formal application for a construction license in the middle of 2015 at the latest.
