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
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radio ...
. As of November 2022, there are 438 operable power reactors in the world, with a combined electrical capacity of 394 GW. Additionally, there are 60 reactors under construction and 103 reactors planned, with a combined capacity of 66 GW and 105 GW, respectively, while 325 more reactors are proposed.

In the following tables, the ''net capacity'' or ''reference unit power'', expressed in
megawatt (MW), is the maximum electricity output under reference ambient conditions, after deducting the losses within the system including the energy transformers.
