I have put a link to the Wikipedia page, "List of nuclear reactors," below. It seems to be pretty good, and includes some reactors that are not in nuclear plants, such as research reactors.

Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.

French, Belgium, Spain, Italy, Germans, British and Dutch are just a few using this type of energy. Search the internet for the List of nuclear reactors this is a comprehensive annotated list of all the nuclear reactors of the world.

See www.nrc.gov, there is a list of all states with nuclear power reactors.

Nuclear reactors use nuclear fission.
