MHI Delivers 3 of 15 Steam Generators for EDF’s Cruas Nuclear Power Plant

Mitsubishi Heavy Industries (MHI) announced that it has delivered 3 replacement steam generators to Électricité de France S.A. (EDF) for the Cruas Nuclear Power Plant Unit 1 Reactor. The replacement has been certified by France’s nuclear authority  strict regulatory requirements on April 28, 2017.

MHI has received orders from EDF for a total of 15 replacement steam generators since 2005, and is delivering the components.

The replacement steam generators for the 900 MWe pressurized water reactor (PWR) nuclear power plant were ordered in 2010. They are 21 meters in height and 300 tons in weight, and were manufactured at MHI’s Kobe facilities. The steam generators are made of low-alloy steel. Each steam generator contains more than 4,000 heat transfer tubes made from state-of-the-art TT690 alloy material. Steam generators are one of the most important components of a PWR, playing a central role in transferring the thermal energy generated in the reactor vessel from the primary (reactor) cooling system to the secondary (turbine) cooling system, using steam to drive the turbine.

EDF selected the supplier for the steam generators through an international bidding process, with MHI receiving the order jointly with COMEX NUCLÉAIRE (CxN), its alliance partner in the French nuclear power market.
