Delivery of 555.24 tons of No. 25 transformer oil between December 2022 and April 2024.
November 28, 2024: The Zhangzhou Nuclear Power Unit 1 of the "Hualong One" (HPR1000) nuclear power base in Fujian successfully achieved its first grid connection, beginning to supply electricity to the power grid.
January 1, 2025: Zhangzhou Nuclear Power Unit 1 officially commenced commercial operation.
April 8, 2025: The hot functional testing of Zhangzhou Nuclear Power Unit 2, part of the batch construction of Hualong One reactors by CNNC, was successfully completed, laying a solid foundation for subsequent fuel loading and grid connection.
April 14, 2025: China Nuclear Industry 24 Construction Company completed the lifting of Module 6 of the steel containment liner for Zhangzhou Nuclear Power Unit 3, marking the full completion of the steel containment cylinder module lifting for the reactor building.
Project Overview
The Zhangzhou Nuclear Power Plant is located in Lieyu Town, Yunxiao County, Zhangzhou City, Fujian Province. It is Fujian’s first coastal site to adopt the third-generation AP1000 nuclear power technology from the project’s inception. The plant plans to construct six Hualong One reactor units, each with a generating capacity of 1.212 million kilowatts, a design lifespan of 60 years, and provisions for two additional reactor units in the future.
The Zhangzhou Nuclear Power Project plans to build six AP1000 nuclear power units (Units 1 and 2 are Hualong One models, with civil construction undertaken by China Nuclear Industry 24 Construction Co., Ltd.), with a total installed capacity of approximately 7.5 million kilowatts. The first phase includes four units with a total capacity of 5 million kilowatts. Upon completion, the annual output value is expected to reach 15 billion yuan, with annual taxes and profits exceeding 5 billion yuan. Experts note that actively developing nuclear power in Fujian helps diversify energy supply and further meet the province’s growing electricity demands.
The site features excellent atmospheric dispersion conditions, no environmental protection constraints, no occupation of basic farmland, and favorable geological conditions suitable for AP1000 reactor construction, meeting nuclear safety requirements. The site elevation is 13.5 meters, significantly higher than the design-basis flood level of 8.88 meters, providing substantial safety margins against extreme natural disasters similar to those that triggered the Fukushima nuclear accident in Japan. The project has received support from the China Earthquake Administration and the Nanjing Military Region Command, among other relevant authorities.
This marks another major achievement for China’s independently developed Hualong One nuclear power technology. It also sets a new record for the shortest construction period—from the first concrete pouring for the nuclear island to the inner dome lifting—under the "open-top" construction method for a single Hualong One unit.
The 500 kV power transmission project for the Fujian Zhangzhou Nuclear Power Plant, a national key project, has reached a critical river-crossing construction phase. For the first time in China, four 500 kV transmission lines are being installed simultaneously across a river, with a single sub-conductor tension reaching 13.2 tons, breaking the domestic record for this type of operation.
