Nuclear power-producing countries

While nuclear energy is not used in all countries, it is used in plenty. Many use it for research, a ton for medical uses. In this post, all countries currently using nuclear energy for electricity will be mentioned, as well as all their NPPs by name, excluding any decommissioned and cancelled ones. There will be no story provided about the NPPs, this is simply a list. Any country with no current operating NPPs, even if they are under construction, will not be mentioned. The countries are in alphabetical order. For anyone wishing to see a map of all NPPs, there is an interactive worldwide map of them, where you can find much information about specific NPPs.
