First Zhangzhou unit begins supplying power
Unit 1 of the Zhangzhou nuclear power plant in China's Fujian province has been connected to the grid, China National Nuclear Corporation has announced. The unit is the first of four Hualong One (HPR1000) reactors under construction at the site.

The reactor began supplying electricity to grid at 7.46am on Thursday, CNNC said, marking "major progress in the mass production of Hualong One by China National Nuclear Corporation, and makes new contributions to the optimisation of the national energy structure and the realisation of the 'dual carbon' goals".
It added: "A series of tests will be carried out as planned to further verify the performance of the unit to meet commercial operation conditions."
In May 2014, the local government gave approval for Phase I of the Zhangzhou plant, comprising two AP1000 units. The National Nuclear Safety Administration gave approval in December 2015 for the AP1000 units and confirmed site selection in October 2016. Construction of Phase I had originally been expected to start in May 2017. However, CNNC subsequently decided to use the HPR1000 (Hualong One) design instead. Two more Hualong One units are planned for Phase II of the plant and a further two proposed for Phase III.

Construction of Zhangzhou 1 began in October 2019, with that of unit 2 starting in September 2020.
In September 2022, China's State Council approved the construction of two further Hualong One units as Phase II of the Zhangzhou plant. First concrete for the nuclear island of unit 3 was poured on 22 February this year. First concrete for unit 4 was poured last month.
The Zhangzhou project - with a total investment of over CNY100 billion (USD14 billion) - is owned by CNNC-Guodian Zhangzhou Energy Company, a joint venture between CNNC (51%) and China Guodian Corporation (49%).
CNNC said the Zhangzhou plant is the starting point for the mass construction of Hualong One reactors and "is currently the world's largest Hualong One nuclear power base". It plans to construct a total of six Hualong One nuclear units at the site. Currently, four Hualong One units are under construction there.
"At present, the total number of Hualong One units in operation and under construction at home and abroad has reached 33, making it the third-generation nuclear power technology with the largest number of units in operation and under construction in the world," CNNC noted.
