On the morning of the 24th, China Eastern Electric Group's Dongfang Motor Co., Ltd. successfully manufactured and shipped the world’s largest single-capacity nuclear power generator — the 1,750 MW unit for Taishan Nuclear Power Station No. 1 — from Deyang City, Sichuan Province. This milestone marks a significant achievement in the field of large-scale nuclear energy technology.
According to Dongfang Motor, the generator underwent rigorous type tests before delivery, including critical assessments of temperature rise, efficiency, and vibration under rated conditions. All tests were completed successfully, confirming that the generator meets and exceeds all contractual specifications. This accomplishment highlights Dongfang Electric's growing expertise in high-performance, large-capacity generator manufacturing and reinforces its position as a leader in the industry.
The Taishan Nuclear Power Plant is China’s first and the third globally to adopt EPR (European Pressurized Reactor) third-generation nuclear technology. It represents the largest collaborative project between China and France in the nuclear energy sector. Dongfang Motor supplied all the nuclear generators for the first phase of the project, with each unit boasting an impressive capacity of 1,750 megawatts. This generator is considered the most complex, challenging, and heavy unit ever built by the company.
To meet the demanding requirements, Dongfang Electric developed innovative processes, including a new rotor coil assembly method, a novel stator bar manufacturing technique, an improved retaining ring assembly process, and an advanced oil seal system assembly. These innovations showcase the company's strong R&D and production capabilities, along with its strict adherence to the "Four Everythings" nuclear safety culture.
As of now, Dongfang Electric has produced 14 nuclear power generators, totaling approximately 15,790 megawatts. This makes it the largest domestic manufacturer of nuclear power generators in China. With continued advancements and a commitment to excellence, the company is well-positioned to lead the future of nuclear energy development. (Reporter: Hemingway)
