Changjiang Nuclear Power Plant is a nuclear power plant in Tangxing Village of Haiwei Township, Changjiang Li Autonomous County in the province of Hainan.[1] It is the first power plant of its kind in the province.


Construction of the first phase of the plant which consists of two reactors was approved by the National Development and Reform Commission in July 2008. Site works began in December 2008 and the first concrete was poured at the first unit on 25 April 2010. The plant was built by China National Nuclear Corporation and China Huaneng Group.[2][3] Unit 1 was connected to the electricity grid on 7 November 2015 and is commercially operating starting on 25 December 2015.[4]

In July 2019 China National Nuclear Corporation announced it would start building a demonstration ACP100 small modular reactor on the north-west side of the site by the end of the year.[5]

Technical features[edit]

The plant will be built in two phases, both consisting of two CNP-600 pressurized water reactors, with a capacity of 650 MW each. The first unit was connected to the grid November 7, 2015 and second unit is scheduled for operations start by 2016. More than 70% of the equipment was planned to be indigenously made.[2]

Unit Type Construction start Operation start Notes
Phase I
Changjiang 1 CNP-600 25 April 2010 25 December 2015 [2][6]
Changjiang 2 CNP-600 21 November 2010 12 August 2016 [7][8]
Phase II
Changjiang 3 CNP-600 [9]
Changjiang 4 CNP-600 [9]

Pumped storage hydroelectricity[edit]

The 600 MW Hainan Qiongzhong pumped-storage hydroelectric plant helps to balance the nuclear plant by absorbing nighttime production and generating electricity during the day.[10]
