Nuclear power - Wikipedia
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants.
What is Nuclear Energy? The Science of Nuclear Power
Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together. The nuclear energy harnessed around the world today to produce electricity is through nuclear fission, while technology to ...
Nuclear energy | Definition, Sources, Uses, & Facts | Britannica
Nuclear energy, energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms. One method of releasing nuclear energy is by controlled nuclear fission, used in nuclear power plants around the world. Another method, controlled nuclear fusion, has not yet been perfected.
Nuclear Power in the World Today
Nuclear provides over 20% of the world’s low-carbon electricity. Nuclear is the world's second largest source of low-carbon power. Over 50 countries utilize nuclear energy in about 220 research reactors. In addition to research, these reactors are used for the production of medical and industrial isotopes, as well as for training.

Nuclear power plant - Wikipedia
A nuclear power plant (NPP), [1] also known as a nuclear power station (NPS), nuclear generating station (NGS) or atomic power station (APS) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. As of October 2025, the ...
Nuclear power | Definition, Issues, & Facts | Britannica
Nuclear power, electricity generated by power plants that derive their heat from fission in a nuclear reactor. Except for the reactor, a nuclear power plant is similar to a large coal-fired power plant, with pumps, valves, steam generators, turbines, electric generators, condensers, and associated equipment.
Nuclear - Department of Energy
Nuclear power, the use of sustained nuclear fission to generate heat and electricity, provides around 6 percent of the world's energy.
Five Reasons the Clean Energy Transition Needs Nuclear Power
Nuclear energy ranks among the cleanest power sources when assessed across its entire lifecycle. Lifecycle analyses consider every stage — from uranium mining and fuel fabrication to plant construction, operation and decommissioning. Even with all these phases included, nuclear power’s total greenhouse gas emissions remain extremely low, comparable to wind and lower than solar. This is ...
