Nuclear power by country

Nuclear power plants currently operate in 32 countries.[2] 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%.[3]

The Cattenom Nuclear Power Plant in France. France produces around three quarters of its electricity by nuclear power.[1]

China has the fastest growing nuclear power program with 13 new reactors under construction,[4] and a considerable number of new reactors are also being built in India, Russia and South Korea.

Some countries operated nuclear reactors in the past but have currently 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.[5]

Several countries are currently 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. 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.[6][7] 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.[8] In 2021, Iraq declared it plans to build 8 nuclear reactors by 2030 to supply up to 25% electric power in the grid that currently suffers from shortages.[9]

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.[2] 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.[2] As of December 2020, 448 reactors with a net capacity of 397,777 MWe are operational, and 51 reactors with net capacity of 53,905 MWe are under construction. Of the reactors under construction, 13 reactors with 12,565 MWe are in China and 6 reactors with a capacity of 4,194 MWe are in India.[11]
