nuclear energy, energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms. It is distinct from the energy of other atomic phenomena such as ordinary chemical reactions, which involve only the orbital electrons of atoms.

Nov 15, 2022 · 15 Nov 2022. Andrea Galindo, IAEA Office of Public Information and Communication. 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.
- Space Exploration. A great deal of what we know about deep space has been made possible by radioisotope power systems (RPSs). These small nuclear power sources are used to power spaceships in the extreme environments of deep space.
- Nuclear Energy. Nuclear provides nearly 20% of our electricity in the United States. It’s also the nation’s largest source of clean energy—making up nearly 60% of our emissions-free electricity.
- Medical Diagnosis and Treatment. Approximately one-third of all patients admitted to U.S. hospitals are diagnosed or treated using radiation or radioactive materials.
- Criminal Investigation. Criminal investigators frequently rely on radioisotopes to obtain physical evidence linking a suspect to a specific crime. They can be used to identify trace chemicals in materials such as paint, glass, tape, gunpowder, lead, and poisons.
Oct 19, 2023 · Nuclear energy can be used to create electricity, but it must first be released from the atom. In the process of nuclear fission , atoms are split to release that energy. A nuclear reactor , or power plant , is a series of machines that can control nuclear fission to produce electricity .
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.

Beyond electricity generation, there are many applications that can use nuclear power. (Image: A. Vargas/IAEA)
The role that nuclear energy plays in the energy system is therefore very specific to the given country. How much of our energy comes from nuclear power? How is its role changing over time? In this article we look at levels and changes in nuclear energy generation across the world, and its safety record in comparison to other sources of energy.
