Construction of Hualong One unit began in October 2020
Hot functional testing has been completed at China’s Taipingling-2 nuclear power unit under construction in the southern province of Guangdong, the China Nuclear Energy Association (CNEA) said.
Hot testing typically spans several weeks and involves a series of tests on key systems to verify their performance under standard operating conditions, conducted without loading any nuclear fuel into the reactor core.
Taipingling-2 is a 1,116-MW Hualong One pressurised water reactor unit being developed by China General Nuclear (CGN). Construction began in October 2020.
CGN previously said there will be six domestic Hualong One pressurised water reactor units at the Taipingling site. Units 1 and 3 have been under construction since December 2019 and June 2025.
Hot functional testing for Taipingling-1 was completed in September 2024, while the steel base of the containment building for Taipingling-3 was laid down earlier this week.
The Hualong One, also known as the HPR1000, is a domestically developed pressurised water reactor that combines features from China National Nuclear Corporation’s ACP1000 and China General Nuclear’s ACPR1000+ designs.
Hualong One is now China’s flagship reactor technology comprising about half of all reactor new-build projects in the country.
