This field describes nuclear energy used for 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. Watts are a measure of power, describing the rate at which electricity is being used at a specific moment. A gigawatt is 1 billion watts.
