By the end of 2025, there were 59 nuclear power units connected to the grid in Main China, with a total installed capacity of 62.25894 million kilowatts, ranking second in the world after the United States with 94 units China's total installed capacity of grid-connected units was second only to the United States (96.952 million kilowatts) and France (63 millionowatts), ranking third in the world. According to the construction progress of nuclear power units under construction, it is expected that China's total installed capacity of nuclear power units operation will exceed France in 2026, reaching the second place in the world. In 2025, one unit was connected to the grid for the first, which is unit 2 of Zhangzhou nuclear power plant with an installed capacity of 1.212 million kilowatts. In 2025, the of nuclear power units connected to the grid in China increased by 1.7% year-on-year, and the total installed capacity increased by 1.8% yearon-year.
By the end of 2025, there were 35 nuclear power units under construction in China, with a total installed capacity of 4.216 million kilowatts, exceeding that of India (ranking second in the world in terms of the number of nuclear power units under construction) and Russia (ranking third the world in terms of the number of nuclear power units under construction), and ranking first in the world for the 19th consecutive year (India has 6 nuclear power under construction with a total installed capacity of 47.68 million kilowatts, and Russia has 5 nuclear power units under construction with a total installed capacity of 0 million kilowatts). In 2025, a total of 9 nuclear power units achieved the first concrete pouring of the nuclear island (FCD), a total installed capacity of 11.033 million kilowatts, in order of the start time, which are units 1 of Luhfeng, 2 Shidong Bay Phase I Expansion, 3 of Huizhou, 1 of Jingqimen, 1 of Zhaoyuan, 3 of Sanao, 6 of Ningde, 2 of Luhfeng and 1 of Bailong, etc.
In 2025, China a total of 10 nuclear power units, marking the fourth consecutive year with an approval of more than 10 units. By the end of 2025, there 112 nuclear power units in operation, under construction and approved for construction in China, with a total installed capacity of 126 million kilowatts, ranking in the world for the third consecutive year. China's nuclear power units are distributed in 25 nuclear power plants or nuclear power bases in 8 eastern coastal provinces. The8 coastal provinces are Liaoning, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong, Guangxi and Hainan from north to. Among them, nine nuclear power plants, including Xudabu, Zhaoyuan, Xuyi, Jingqimen, San'ao, Luhf, Huizhou, Lianjiang and Bailong, are newly built nuclear power plants, and there are currently no nuclear power units that have been built and put into operation The situation of nuclear power units in operation, under construction and approved for construction in each province of China is shown in the following figure
