Under the contract – signed with Dongfang Electric International and Dongfang Heavy Machinery, subsidiaries of Dongfang Electric Group – Doosan Enerbility will deliver eight forged components by 2029. The order includes four channel heads and four tube sheets, which are among the most critical materials used in nuclear steam generators. The forgings to be supplied measure 5 metres in diameter and weigh up to 130 tonnes.
Doosan Enerbility said it leverages its world-class 17,000-tonne press and ultra-large forging technologies at its Changwon headquarters forging plant to manufacture and supply major nuclear power components to the global market.

The construction of two Guohe One (CAP1400) reactors – an enlarged version of the CAP1000 PWR developed from the Westinghouse AP1000 – as the initial phase of State Power Investment Corporation’s Laiyang plant was among eight units approved during a State Council executive meeting chaired by Chinese Premier Li Qiang on 31 July this year. The Laiyang plant will eventually house six such units. SPIC is fully responsible for the investment, construction and operation of the Shandong Laiyang Nuclear Power Project.
Last year, Doosan Enerbility announced it had been contracted to supply the same forged components for Laiyang units 3 and 4. The company had previously supplied steam generator forgings for the Haiyang plant, also in Shandong province, which features AP1000 reactors.
“This consecutive order for Laiyang units 5 and 6 is particularly meaningful, as it reaffirms the recognition of our technological and quality competitiveness in China’s nuclear power market,” said Jongdoo Kim, CEO of Doosan Enerbility. “Building on our manufacturing expertise and ultra-large forging technologies, we will continue to strengthen our competitiveness in the global nuclear power supply chain.”
