This is a list of all the commercial nuclear reactors in the world, sorted by country, with operational status. The list only includes civilian nuclear power reactors used to generate electricity for a power grid. All commercial nuclear reactors use nuclear fission. As of December 2024, there are 419 operable power reactors in the world, with a ...
This table lists all currently operational power stations. Some of these may have reactors under construction, but only current net capacity is listed. Capacity of permanently shut-down reactors is not included, but capacity of long-term shut-down reactors (today mainly in Japan) is included.

This is an annotated list of all the nuclear fission-based nuclear research reactors in the world, sorted by country, with operational status. Some "research" reactors were built for the purpose of producing material for nuclear weapons.
As of September 2023, the International Atomic Energy Agency reported that there were 410 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. [2] [3] [4] Most nuclear power plants use thermal reactors with enriched uranium in a once-through fuel cycle.
A fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing so, it bypasses the Carnot cycle and can achieve efficiencies of up to 90% instead of 40–45% attainable by efficient turbine-driven thermal reactors.
Nuclear power plants operate in 32 countries and generate about a tenth of the world's electricity. [2] Most are in Europe, North America and East 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]
This category is for power reactor types of which more than one example has been built, or for which that was or still is the intention. These types are not exclusive, for example a VVER is a PWR. It may not even always be clear what is included in a type: In some contexts an ABWR is a type of BWR, but in most contexts it is not.
