Nuclear power in China
overview of nuclear power in China
China operates the world's second-largest fleet of nuclear power plants, behind the United States. As of September 2026, 64 nuclear reactors with net capacity 63.409 gigawatts electrical (GWe) have been installed, compared to the US's 94 plants and 96.9 GWe. At the same time, there are over 37 reactors under construction with a total net capacity of 38 GWe, ranked first for the 18th consecutive year. 24 reactors (about 25 GWe) have been approved. In 2025, China's nuclear power generated 450 TWh of electricity, ranked second globally, accounting for 4.82% of the 2025 total energy production in China.
Nuclear power has been looked into as an alternative to coal due to increasing concerns about air quality, climate change and fossil fuel shortages.
China aims to generate 200 GWe by 2035, produced by 150 additional reactors, at a cost of US$440 billion. China has two major nuclear power companies, the China National Nuclear Corporation operating mainly in northeast China, and the China General Nuclear Power Group operating mainly in southeast China.
China aims to maximize self-reliance on nuclear reactor technology manufacturing and design, although international cooperation and technology transfer are also encouraged.
Advanced pressurized water reactors (PWR) such as the Hualong One, CAP-1000, Guohe One are the mainstream technology in the near future, and the Hualong One is also exported to Pakistan and will be exported to Kazakhstan.

Why this record matters
“Nuclear power in China” is worth following because a concise public description often conceals a longer documentary argument. Here, Nuclear, power and China provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q782552. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026, 2025, 2035 and 1000.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
