On April 14, 2026, Shanghai - China's first nuclear power plant emergency diesel generator set with independent intellectual property rights, "Nuclear Diesel No.1," has recently completed the delivery of its first set, marking China's achievement of full chain independent controllability in the field of key nuclear power equipment. The unit was led by China General Nuclear Power Engineering Co., Ltd. for research and development, and took five years to overcome 18 major technological improvements, resulting in 26 patents and passing a 1000 hour reliability test.
The "Nuclear Diesel One" has the characteristics of fast and reliable start-up, an average time between failures of over 2000 hours, and high intelligence. Its noise control indicators have reached the international advanced level, which can meet the strict requirements of nuclear power plant safety systems for power supply. Zhou Jianping, Vice President of CGN, said, "In the past, nuclear power emergency diesel units relied on imports or foreign patent authorizations. The birth of 'Nuclear Diesel One' has completely changed this situation and provided solid guarantees for the safety of the nuclear power industry chain
It is reported that the unit has been applied in Fujian Ningde Nuclear Power Phase II, Guangdong Taipingling Nuclear Power Phase II and other projects, and is planned to cover 18 under construction units in the mass construction of "Hualong One". Industry experts point out that the autonomy of nuclear emergency diesel generator sets not only reduces equipment costs, but also improves operation and maintenance efficiency through localized supply chains, providing a "Chinese solution" for the global nuclear power market.
In addition, the research and development of "Nuclear Diesel One" has driven collaborative innovation in the upstream and downstream industrial chains. Weichai Power, Yuchai International and other enterprises participate in the supply of core components to promote the technological upgrading of domestically produced high-power diesel engines. Fabrizio Moz, Vice General Manager of Weichai Group, said, "The deep integration of the Chinese and French technical teams has made Weichai Boduan the fifth manufacturer in the world to have the ability to produce high-power data center products
