The commencement of commercial operations for Unit 1 of the Zhangzhou nuclear power project marks a significant milestone for China National Nuclear Corporation (CNNC) and the broader energy landscape in China. Located in Fujian Province, this project is not just another notch on the belt for CNNC; it’s a strategic move that aligns with the nation’s ambitious goals to diversify its energy sources and achieve carbon neutrality.
Unit 1 boasts a net design capacity of 1.12 gigawatts (GW), a powerhouse that was connected to the national grid in November 2024. This facility adheres to the latest technical standards and global safety requirements, showcasing China’s commitment to not only maintaining safety but also pushing the envelope in nuclear technology. The Hualong One design, a domestically developed third-generation pressurized water reactor technology, is at the heart of this project. Each unit has the potential to generate over ten billion kilowatt-hours of electricity annually, enough to power a million people’s homes in moderately developed countries.
What does this mean for the environment? The figures speak volumes: the operation of Unit 1 is expected to cut down coal consumption by 3.12 million tonnes and reduce carbon dioxide emissions by 8.16 million tonnes each year. These aren’t just numbers; they represent tangible progress towards cleaner air and a more sustainable future.
The journey to this operational milestone wasn’t without its hurdles. The initial approval for Zhangzhou’s Phase I, which includes two AP1000 units, came in May 2014. However, CNNC made a strategic pivot to the Hualong One design, which delayed construction until May 2017. The actual construction of Unit 1 kicked off in October 2019, reflecting the complexities and challenges often associated with large-scale nuclear projects.
Currently, Unit 2 is under construction, with the inner dome installed in August 2022. Utilizing open-top construction technology, this unit has set records for speed, showcasing a level of efficiency that could redefine timelines for future projects. Looking ahead, Phase II and III of the Zhangzhou nuclear power plant are poised to add four more Hualong One units, culminating in a total of six units.
Globally, the Hualong One design is gaining traction, with 33 units either under construction or operational. This trend underscores a growing acceptance of Chinese nuclear technology on the world stage, potentially reshaping the dynamics of global energy supply.
As the world grapples with climate change and energy security, the implications of projects like Zhangzhou extend far beyond China’s borders. They could serve as a blueprint for other nations looking to bolster their energy independence while simultaneously addressing environmental concerns. The success of Unit 1 not only heralds a new era for China’s energy strategy but also sparks a broader conversation about the future of nuclear energy worldwide.
