China”s nuclear power industry has entered a “fast track” of high-quality development, with its total scale of units in operation, under construction, and approved for development continuing to rank first in the world, the Chinese Nuclear Society announced on Wednesday.
By the end of 2025, China reached a total of 112 nuclear power units — including those in operation, under construction, and newly approved — with a combined installed capacity of 126 gigawatts (GW). Since 2022, the country has maintained a steady momentum, approving 10 or more nuclear units annually for four consecutive years.
Wang Shoujun, president of the Chinese Nuclear Society, said that the nation’s nuclear science and technology innovation capabilities have seen a comprehensive upgrade.
Significant leaps have been achieved across multiple frontiers, including third- and fourth-generation reactors, small modular reactors (SMRs), controlled nuclear fusion, and advanced nuclear fuel cycles, he said.
“China remains committed to the ‘three-step’ strategy of thermal reactors, fast reactors, and fusion reactors,” Wang said.
He noted that the country is steadily increasing the proportion of nuclear energy in its total energy consumption while ensuring a safe and stable nuclear fuel supply through a closed-loop fuel cycle technical route.
Key projects are progressing rapidly across the country. The Hualong One, China’s self-developed third-generation technology, is undergoing mass construction, while the Linglong One — the world’s first commercial land-based SMR — is advancing steadily. Furthermore, the high-temperature gas-cooled reactor demonstration project continues to operate with high efficiency.
According to Wang, the industry’s high-quality growth is also characterized by a surge in localization and digitalization, while the self-reliance level of the nuclear technology industrial chain has also increased significantly, alongside accelerated digital transformations.
“China’s nuclear industry has become a major engine driving the sustainable development of the global nuclear sector,” Wang added, highlighting the nation’s pivotal role in the world’s transition to green energy.
