The first safety-related concrete has been poured for the nuclear island of unit 4 at the Zhangzhou nuclear power plant in Fujian province, China National Nuclear Corporation announced. The plant will eventually house six Hualong One reactors.

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.

CNNC issued the environmental impact assessment for Zhangzhou units 3 and 4 in October 2020. In September 2022, China’s State Council approved the construction of two Hualong One units as Phase II of the Zhangzhou plant.

“The Zhangzhou nuclear power plant is the starting point for the mass production of Hualong One,” CNNC said. "So far, four units have started construction, and safety and quality are all under good control.

“Unit 1 is expected to be put into operation and generate electricity in 2024; unit 2 is fully advancing the relevant work before cold testing; unit 3 started construction on 22 February this year; and the preliminary work of units 5 and 6 is progressing in an orderly manner.”

The Zhangzhou project is owned by CNNC-Guodian Zhangzhou Energy Company, a joint venture between CNNC (51%) and China Guodian Corporation (49%).

The first two demonstration units of CNNC’s version of the Hualong One design at the Fuqing plant in Fujian province have both already started up. Unit 5 entered commercial operation on 30 January 2021, with unit 6 following on 25 March 2022. Two Hualong One reactors have also been constructed as units 2 and 3 of the Karachi plant in Pakistan’s Sindh province. These entered commercial operation in May 2021 and April 2022, respectively.

In addition to Zhangzhou units 1-4, CNNC is also building two Hualong One reactors as units 3 and 4 of the Changjiang plant, in Hainan province, construction of which began in March 2021 and December 2021, respectively.

It is also preparing to start construction of Phase I of the Jinqimen plant in Zhejiang province, which will feature two Hualong One reactors.
