The Fuqing nuclear plant’s Unit 6, one of two Chinese-designed and -developed Hualong One reactors at the site, has entered commercial operation, China National Nuclear Corporation (CNNC) announced on March 25. The milestone was reached some 14 months after the reactor’s twin, Fuqing-5, became the first Hualong One in the world to enter commercial operation.

Also known as the HPR1000, the Hualong One is a 1,000-MWe Generation III pressurized water reactor that incorporates design elements of CNNC’s ACP1000 and China General Nuclear Power Group’s ACPR1000+.

Unit 3 at Pakistan’s Karachi nuclear power plant has been connected to the national grid, China National Nuclear Corporation (CNNC) announced on March 4, making it the second Hualong One reactor outside of China to have reached the last major step prior to commercial operation. (The distinction of being the first belongs to Unit 3’s twin, Karachi-2, which was connected to the grid in March 2021 and entered commercial operation in May.)

Karachi-3 had achieved criticality on February 21 after completing hot functional testing and entering the fuel loading stage last November.

Unit 2 at Pakistan’s Karachi nuclear power plant officially began commercial operation in late May, gaining the distinction of being the first Hualong One reactor outside of China to do so, China National Nuclear Corporation announced last week. Construction of Karachi-2 began in August 2015, and connection to the grid was accomplished in March of this year.

Unit 5 at the Fuqing nuclear plant in China’s Fujian Province has entered commercial operation, becoming the world’s first Hualong One reactor to do so, China National Nuclear Corporation (CNNC) announced on January 30.

The unit was connected to the power grid in late November of last year, after having achieved initial criticality the previous month.

Also known as the HPR1000, the Hualong One is a Chinese-designed and -developed 1,000-MWe Generation III pressurized water reactor, incorporating design elements of CNNC’s ACP1000 and China General Nuclear’s ACPR1000+ reactors.

There’s more: Fuqing-5’s twin HPR1000, Fuqing-6, is scheduled for commercial startup later this year. In addition, CNNC is building two Hualong One reactors at the Zhangzhou site in Fujian Province (construction of Unit 1 began in October 2019, while Unit 2’s construction commenced last September) and one at Taipingling in Guangdong Province, with another planned for the site.

Also, China General Nuclear is building two Hualong One reactors (Units 3 and 4) at its Fangchenggang plant in Guangxi Province (2022 planned startup), while two CNNC units are under construction at Pakistan’s Karachi plant (commercial start dates of 2021 and 2022).

Unit 5 at China National Nuclear Corporation’s (CNNC) Fuqing nuclear plant in southeastern China’s Fujian Province has become the world’s first Hualong One reactor to be connected to the power grid, the company announced on November 27. “It was confirmed on-site that all technical indicators of the unit met the design requirements and that the unit was in good condition,” CNNC said.

Fuel loading at Fuqing-5 began on September 4, following the issuance of the reactor’s operating license by China’s Ministry of Ecology and Environment. The loading of 177 sets of fuel assemblies was completed on September 10, and initial criticality was achieved on October 21. The unit is scheduled to enter commercial operation before the end of the year.

Also known as the HPR1000, the Hualong One is a Chinese-designed and -developed 1,000-MWe Generation III pressurized water reactor, incorporating design elements of CNNC’s ACP1000 and China General Nuclear’s ACPR1000+ reactors. Fuqing-5’s twin HPR1000, Fuqing-6, is scheduled to start contributing power to the grid next year.
