Steam Generator
TOKYO, October 16, 2026- (JCN Newswire )- Mitsubishi Heavy Industries, Ltd.(MHI )has actually finished the shipment of 3 replacement steam generators(SGs) to Électricité de France S.A.(EDF, headquartered in Paris )for its nuclear reactor in France. Production of these replacement SGs was finished at MHI’s Kobe center (Hyogo-ku, Kobe) in January 2024. At the end of February this year, they acquired a certificate adhering to stringent requirements needed by the French nuclear regulative authority, and were consequently transferred to France. MHI has actually gotten orders for an overall of 9 replacement SGs from EDF, and the staying 6 systems are presently being produced at MHI’s Kobe centers, with shipment set up from 2028 onwards.
EDF purchased the recently provided replacement SGs in 2019 from both MHI and Onet Technologies( 1) for a 900 MWe pressurized water reactor (PWR) nuclear reactor. They are arranged to be set up in Unit 2 of the Cruas Nuclear Power Plant, situated in the Ardèche department of southeastern France.
SGs are amongst the most essential parts of PWR plants, moving the thermal energy created in the reactor vessel from the main cooling system (reactor system) to the secondary cooling system (turbine system) to create steam to drive the turbine. Each SG procedures around 21 meters in height and has an overall weight of around 330 lots. Roughly 4,500 heat transfer tubes made from TT690 alloy( 2 ), which include high deterioration resistance, are placed into a pressure-resistant vessel made from low-alloy steel( 3 ).
MHI has actually provided a cumulative overall of 15 replacement SGs to EDF given that 2005, omitting those provided this time. EDF is among the world’s biggest power energies, running 57 PWR plants in France. In accordance with French federal government policy to extend the operating life of nuclear reactor beyond 40 years, EDF had actually been gradually changing SGs at its PWR plants that began operation in the 1980s. As France continues to enhance its nuclear regulative requirements, the effective shipment of replacement SGs that completely abide by the policies shows that MHI’s technological competence, producing quality, dependability, and ability to adjust to French requirements and guidelines are extremely concerned.
MHI has a tested performance history of providing more than 30 replacement SGs to abroad nations consisting of France, Belgium, and the United States. MHI has actually gotten orders for more than 130 SGs in overall, consisting of both brand-new setups and replacements jobs in Japan. MHI continues to add to extending the running life, in addition to improving the security and financial performance, of PWR plants both in Japan and worldwide.
From the perspective of carbon neutrality and energy security, there has actually been an increase in need for usage of nuclear power worldwide. MHI will continue to add to the safe and steady operation of nuclear reactor by providing items needing high dependability to both the domestic and abroad nuclear markets, consisting of France. In addition, through the production of replacement SGs, MHI will hand down the extensive technological abilities it has actually cultivated over several years as a nuclear reactor producer to the next generation, while continuing to provide premium devices from Kobe to the world.
(1) Headquartered in Marseille, France, Onet Technologies focuses on offering expert upkeep and assistance services for nuclear centers and has actually remained in collaboration with MHI because 2002.
(2) TT690 is a nickel, chromium, and iron alloy that has actually been specifically heat-treated to boost rust resistance. It is utilized as the product for SG heat transfer tubes, providing remarkable rust resistance under high-temperature and high-pressure conditions.
(3) Low-alloy steel describes steel consisting of 5% or less of alloying aspects. SGs are produced as pressure-resistant vessels utilizing strong low-alloy steel (manganese-molybdenum-nickel steel).
