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 power plant has achieved initial criticality, becoming the very first Hualong One reactor to reach that milestone, the company announced on October 22. If all goes according to schedule, the unit will enter commercial operation later this year.

Fuel loading for Unit 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.

Also known as the HPR1000, the Hualong One is a Chinese-designed, 1,000-MWe Generation III pressurized water reactor. Fuqing-5’s twin HPR1000, Fuqing-6, is scheduled to start contributing power to the grid next year.

Located in China’s Fujian Province, Fuqing also houses four 1,000-MWe CPR-1000 PWRs, with commercial start dates of November 2014, October 2015, October 2016, and September 2017.

Unit 5 at the Tianwan nuclear power plant completed its full-power continuous operation assessment on September 8, meeting the conditions for commercial operation, China National Nuclear Corporation reported. The domestically designed ACPR-1000 pressurized water reactor will become CNNC’s 22nd reactor to provide power to China’s electric grid, raising the CNNC fleet’s installed capacity from 19.112 million kilowatts to 20.230 million, according to the company.

Tianwan-5 construction officially commenced on December 27, 2015, with the pouring of safety-related concrete. China’s National Nuclear Safety Administration issued a 40-year operating license for the unit on July 7 of this year, and two days later CNNC announced that first fuel loading had been completed. The reactor achieved initial criticality on July 27 and connected to the grid on August 8. Once commercial operation of the unit has begun, Tianwan will boast five operating reactors.
