The World Factbook

The World Factbook now includes a new field in the Energy category that describes “Nuclear energy” used for the production of electricity. The information covers all countries with operational nuclear reactors used to produce electricity; the information does not include research reactors. Subfields include the current number of operational nuclear reactors, the number of nuclear reactors under construction, the net capacity of operational nuclear reactors expressed in gigawatts (GW), the percent of total electricity production from nuclear energy, the percent of total energy produced from nuclear energy, and the number of nuclear reactors permanently shut down.
