Nuclear power plants operate in 32 countries, generating about 10% of the world's electricity, mainly in Europe, North America, and East Asia. The United States leads in production, while France gets about 70% of its electricity from nuclear power. Some countries like Italy and Lithuania have closed their nuclear plants, while others like the Philippines plan to restart theirs. Poland is planning up to 9 GW by 2040, and Iraq aims to build eight reactors by 2030. Hong Kong imports much of its nuclear energy from the Daya Bay Nuclear Power Station across the border.

Of the 31 countries in which nuclear power plants operate, only France, Slovakia, and Ukraine use them as the source for a majority of the country's electricity supply as of 2024. Other countries have significant amounts of nuclear power generation capacity. By far the largest nuclear electricity producers are the United States with 781,945 GWh of nuclear electricity in 2024, followed by China with 417,518 GWh.10 As of June 2025, 416 reactors with a net capacity of 376,261 MWe were operational, and 62 reactors with net capacity of 65,040 MWe were under construction.11 Of the reactors under construction, 29 reactors with 30,847 MWe were in China and 6 reactors with a capacity of 4,768 MWe were in India.12
