On 27 April, CCTV News reported that the China Nuclear Energy Association (CNEA) had published a Blue Book entitled China Nuclear Energy Development Report 2025. According to the report, as of 26 April, China had 102 nuclear power units in operation, under construction, or approved for construction, with an installed capacity of 113 gigawatts (GWe). This marks the first time that China’s total nuclear power capacity has topped the world rankings.

The country currently has 28 nuclear power units under construction, with a total installed capacity of 33.65 GWe. This capacity has been the largest in the world for 18 consecutive years. Additionally, China has 58 nuclear power units in commercial operation, with a total installed capacity of 60.96 GWe. China is also expanding the range of applications for nuclear power, with breakthroughs in urban and industrial heating, among other fields. Nuclear technology is also advancing rapidly in the fields of medical applications and international cooperation.

According to the Blue Book, during the 2024–2025 heating season, nuclear power plants such as those at Haiyang, Qinshan, and Hongyanhe provided heating to an area of over 14 million square metres, generating significant economic and social benefits. China has made remarkable breakthroughs in its independent isotope supply capabilities. In 2024, China used commercial nuclear power reactors for the first time to mass-produce carbon-14 isotopes, achieving full localization of this isotope’s supply. Furthermore, the localization of nuclear medical equipment has accelerated, with new progress being made in international cooperation.
