China's Hualong One Nuclear Reactor Goes Online

China's Hualong One Nuclear Reactor Goes Online

On January 30, 2021, China National Nuclear Corporation (CNNC) announced that Unit 5 of China's Fuqing Nuclear Power Plant, the world's first demonstration project to adopt China's indigenous Generation III nuclear power technology Hualong One, also known as HPR1000, was put into commercial operation.

The deployment marks a milestone for the development of China's nuclear power, making China the fourth country to master its indigenous Generation III nuclear power technology following the US, France, and Russia.

Hualong One is CNNC's Generation III nuclear power technology with completely independent intellectual property rights, developed and designed by the corporation on the basis of more than 30 years of nuclear power research, design, manufacturing, construction, and operation experiences.

Yu Jianfeng, chairman of CNNC, said that the corporation will accelerate the progress of mass constructing Hualong One reactors and developing new series technologies in a bid to promote the Hualong One to export and achieve the target of carbon neutrality.

In November 2014, CNNC announced that the fifth and sixth units at Fuqing will use the domestically-developed Hualong One pressurized water reactor design, marking its first deployment. The company had previously expected to use the ACP1000 design for those units, but plans were revised in line with a re-organization of the Chinese nuclear industry. China's State Council gave final approval for the construction of Fuqing units 5 and 6 in April 2015.


With a design life of 60 years, Hualong One reactor adopts a 177-reactor core design that refueling the fuel every 18 months. It innovatively uses a combination of "active and passive" safety systems and a double-shell containment, which meets the latest international nuclear safety requirements.

The installed capacity of each Hualong One unit reaches nearly 1200 MWe, and each unit is able to generate nearly 10 billion kWh of electricity annually, meeting the demand of 1 million population within a moderately developed country.

The electricity generated by a Hualong One unit is equivalent to reducing the consumption of 3.12 million tons of standard coal and emission of 8.16 million tons of carbon dioxide annually, as well as an equivalent to the plantation of over 70 million trees annually.

NOTE: Two Hualong One (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.
