Zhangzhou Nuclear Power Plant Fully Operational with First Two Hualong One Reactors
China has officially brought the first two Hualong One reactors at the Zhangzhou nuclear power plant in Fujian province into commercial operation, marking the establishment of what is now the world's largest nuclear power base built around this advanced domestic technology. This development represents a significant step in China's nuclear energy program and its efforts to enhance clean energy generation.
The Zhangzhou nuclear power plant, located in East China's Fujian Province, is designed to eventually house a total of six Hualong One units. The project is a joint venture, with China National Nuclear Corporation (CNNC) holding 51% and China Guodian Corporation holding 49% through the CNNC-Guodian Zhangzhou Energy Company.
Commercial Operation Milestones
The first unit, Zhangzhou-1, formally commenced commercial operation on January 1, 2025. Following this, Unit 2 entered commercial operation on January 1, 2026, after successfully completing a 168-hour full-power continuous operation test just after midnight on that day. With both Phase I reactors now in service, the site has transitioned from construction to full operation.
Hualong One Technology and Capacity
The Hualong One (HPR1000) is a third-generation pressurized water reactor (PWR), a fully Chinese design with complete intellectual property rights. Each Hualong One unit boasts an installed capacity of nearly 1,200 MWe and is capable of generating approximately 10 billion kilowatt-hours (kWh) of electricity annually.
With the first two units now operational, the Zhangzhou base is expected to generate around 20 billion kWh of electricity each year. This significant output is projected to cut carbon dioxide emissions by approximately 16 million tonnes annually, an environmental benefit comparable to replacing more than 6 million tonnes of standard coal. Once all six planned reactors are completed, the facility is anticipated to supply about 60 billion kWh annually, playing a crucial role in improving Fujian's energy mix and reducing reliance on fossil fuels.
Global Recognition and Future Expansion
The Hualong One technology has garnered international recognition, having received European Utility Requirements certification and passed the UK's Generic Design Assessment. Experts highlight its role in reducing emissions, improving energy security, and strengthening China's position in the global nuclear sector. The successful commissioning of these reactors is seen as a key milestone in China's ambition to transition from a major nuclear power producer to a global leader in nuclear power technology.
Construction is currently underway for Units 3 and 4, with preparatory work also progressing for Units 5 and 6, underscoring China's commitment to expanding its nuclear energy footprint.

It's impressive to see China developing its own advanced nuclear technology and achieving energy independence. However, the sheer scale of this project means any potential incident could have catastrophic regional and global consequences.

What about the waste? No one ever talks about the toxic legacy of these plants.

While the carbon emission reduction is a clear benefit, the long-term safety protocols for operating such a massive nuclear complex must be absolutely flawless, which is a huge challenge.

Cutting millions of tons of CO2? That's a massive win for the environment!
Manolo Noriega
Generating 20 billion kWh annually is a huge achievement for clean energy production. However, the unresolved problem of permanent nuclear waste storage remains a significant moral and environmental burden for future generations.

Another giant centralized power source. Too much control, too many vulnerabilities.
Donatello
China's 'dominance' in nuclear tech is a global security concern, not a benefit.
