Nuclear power by country

Nuclear power plants operate in 32 countries.^[1] Most are in Europe, North America, East Asia and South Asia. The United States is the largest producer of nuclear power, while France has the largest share of electricity generated by nuclear power, at about 70%.^[2] China has the fastest growing nuclear power program with 13 new reactors under construction.^[3]

Some countries operated nuclear reactors in the past but have no operating nuclear plants. Among them, Italy closed all of its nuclear stations by 1990 and nuclear power has since been discontinued because of the 1987 referendums. Kazakhstan and Armenia are planning to reintroduce nuclear power in the future. Belarus has its first nuclear power plant under construction and plans to have it operating by the end of 2020.^{[4][needs update]}

Several countries are operating nuclear power plants but are planning a nuclear power phase-out. These are Belgium, Germany, Spain, and Switzerland. Other countries, like Sweden, and Taiwan are also considering a phase-out. In Sweden, a broad coalition goal was set in 2016 to reach 100% renewable energy by 2040. [1] [2] Any new nuclear reactors would legally have to be built on one of the three existing Nuclear plant sites, and none of the three owners there, neither Vattenfall, Uniper nor Fortum currently plan to build any new nuclear plants [3], due to the high costs associated, although they have indicated that they may change their mind if it turns out in the future that any Small modular reactor were to become commercially competitive. Austria (Zwentendorf Nuclear Power Plant) and the Philippines (Bataan Nuclear Power Plant) never started to use their first nuclear plants that were completely built.

Due to financial, political and technical reasons, Cuba, Libya and Poland never completed the construction of their first nuclear plants, and Australia, Azerbaijan, Georgia, Ghana, Ireland, Kuwait, Oman, Peru and Singapore never built their planned first nuclear plants.^[5][6] Some of these countries are still planning to introduce nuclear power. As of 2020, Poland is in advanced planning phase for 1.5 GW and plans to have up to 9 GW by 2040.^[7] In 2021, Iraq declared it plans to build 8 nuclear reactors by 2030 to supply up to 25% electric power in the grid that suffers from shortages.^[8]

Of the 32 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 2020. Other countries have significant amounts of nuclear power generation capacity. By far the largest nuclear electricity producers are the United States with 789,919 GWh of nuclear electricity in 2020, followed by China with 344,748 GWh.^[1] As of January 2022, 437 reactors with a net capacity of 389,609 MWe are operational, and 52 reactors with net capacity of 53,905 MWe are under construction. Of the reactors under construction, 14 reactors with 14,792 MWe are in China and 6 reactors with a capacity of 4,194 MWe are in India.^[10]
