The first safety-related concrete has been poured for the nuclear island of unit 3 at the Zhangzhou nuclear power plant in Fujian province, China National Nuclear Corporation (CNNC) announced. It is the first of two Hualong One units planned as the second phase of the plant, which will eventually house six such 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. The units are scheduled to enter commercial operation in 2024 and 2025, respectively.
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.
CNNC has now announced that work on Phase II has commenced, with the pouring of first concrete for the nuclear island of unit 3 on 22 February.
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.
"At present, the first four units of Hualong One have been completed and put into operation, and the batch construction is progressing smoothly," CNNC said. "Among them, the Zhangzhou Nuclear Power Project is the starting point for the batch construction of Hualong One: unit 1 is expected to be put into operation in 2024; unit 2 is undergoing cold test-related preparations such as the installation of internal components of the reactor."
In addition to Zhangzhou units 1-3, 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.
Earlier this week, it also held a ground-breaking ceremony for Phase I of the Jinqimen plant in Zhejiang province, which will also feature two Hualong One reactors.
