Doosan Enerbility Signs Contract to Supply Key Materials for Laixiang Nuclear Power Plant Units 5 and 6 in China
Supplying Ultra-Large Forged Components
for Steam Generators: 5m Diameter, 130 Tons Each,
to Be Delivered by 2029
Securing Consecutive Orders After Laixiang Units 3 and 4
Doosan Enerbility announced on July 27 that it has signed a contract with Dongfang Electric International (DEI) and Dongfang Heavy Machinery (DFHM), affiliates of China’s Dongfang Electric Group, to supply ultra-large forged components for steam generators to be installed in units 5 and 6 of the Laixiang Nuclear Power Plant in Shandong Province, China.
The steam generator is a core piece of nuclear power plant equipment that uses heat from the reactor to produce steam, which in turn drives the turbine to generate electricity.
According to this contract, Doosan Enerbility will sequentially supply a total of eight ultra-large forged products for the steam generators of Laixiang units 5 and 6 by 2029. The order comprises four channel heads and four tube sheets.
The channel head serves as a lower forged component providing the inlet and outlet passages for reactor coolant into the steam generator, while the tube sheet is a crucial forged part supporting thousands of heat transfer tubes and separating the reactor coolant from the secondary circuit water.
The forged products to be supplied this time are ultra-large components, measuring 5 meters in diameter and weighing up to 130 tons each. Leveraging one of the world’s largest 17,000-ton presses and its ultra-large forging technology, Doosan Enerbility manufactures and supplies critical nuclear power plant equipment to the global nuclear market.
The Laixiang units 5 and 6 will use China’s next-generation CAP1400 model, which has a capacity of 1,400 MW. Doosan Enerbility had previously secured the order for forged components for the steam generators of Laixiang units 3 and 4 last year, and with this additional order for units 5 and 6, the company has once again demonstrated its technological strength and quality competitiveness in the Chinese nuclear market. In particular, Doosan’s strong evaluation in terms of quality and delivery performance is attributed to its prior experience in supplying steam generator forgings for the Haiyang AP1000 nuclear plant.
Kim Jong Doo, President of Doosan Enerbility, said, “Securing this follow-up contract to supply critical materials for units 5 and 6, following our previous contract for units 3 and 4, is a meaningful recognition of our technological and quality competitiveness in the Chinese nuclear market. Based on our accumulated manufacturing experience and ultra-large forging technology, we will continue to enhance our competitiveness in the global nuclear power supply chain.”
China is pursuing continued construction of new nuclear facilities under its expansion policies, aiming to become the world’s largest nuclear power producer by 2035. Leveraging this contract, Doosan Enerbility plans to expand cooperation with the Chinese nuclear market and increase its supply of key equipment in the global nuclear power supply chain.
