Zhangzhou 1 Pressure Vessel Passes Factory Acceptance Tests

27 Jul 2021  by World Nuclear News   

The reactor pressure vessel for the first of two Hualong One reactors under construction at the Zhangzhou nuclear power plant in China's Fujian province has passed the factory acceptance inspection. Zhangzhou unit 1, construction of which began in September 2020, is scheduled to enter commercial operation in 2024.

The reactor pressure vessel (RPV) was designed by China National Nuclear Corporation's (CNNC's) Nuclear Power Research & Design Institute. A contract was signed with China First Heavy Machinery Company Limited (CFHI) in 2016 for the manufacture of the RPV for Zhangzhou unit 1.

A meeting was held yesterday during which the component was officially accepted. Nuclear Guodian Zhangzhou Energy Company Chairman Chen Guocai, Vice President Tang Chuanbao of the Nuclear Power Research & Design Institute, and China Nuclear Power Engineering Corporation Project Manager Yu Long attended the meeting and jointly witnessed the acceptance.

China's Ministry of Ecology and Environment issued construction licences for Zhangzhou units 1 and 2 on 9 October, 2019 to CNNC-Guodian Zhangzhou Energy Company, the owner of the Zhangzhou nuclear power project which was created by CNNC (51%) and China Guodian Corporation (49%) in 2011. The licences are valid for 10 years. Construction of unit 1 began one week after the issuance of a construction licence, with that of unit 2 starting in September 2020.

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 Hualong One design instead. Two more units are planned for Phase II of the plant and a further two proposed for Phase III.

CNNC began construction of two demonstration Hualong One units at its Fuqing plant in Fujian province in May and December 2015, respectively. The first of these, Fuqing 5, was connected to the grid on 27 November last year, having achieved first criticality on 21 October, and entered commercial operation on 30 January this year. Fuqing 6 is expected to begin operating by the end of 2021.

Construction of two demonstration Hualong One (HPR1000) units is also under way at China General Nuclear's Fangchenggang plant in the Guangxi Autonomous Region. Those units are expected to start up in 2022. CNNC has also started construction of the first of two Hualong One units at Taipingling in Guangdong.

Two HPR1000 units are under construction at Pakistan's Karachi nuclear power plant. Construction began on Karachi unit 2 in 2015 and unit 3 in 2016; the units are planned to enter commercial operation in 2021 and 2022.
