What is Nuclear Energy? The Science of Nuclear Power
WEBNov 15, 2022 · 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 …
Nuclear power - Wikipedia
WEBNuclear 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? | NRC.gov
WEBWhen the electricity is made from atoms splitting apart, it's called nuclear energy. All power plants convert heat into electricity using steam. At nuclear power plants, the heat to make the steam is created when atoms split apart — called fission. When atoms split apart, they release heat.
Nuclear explained - U.S. Energy Information Administration (EIA)
WEBNuclear energy is energy in the core of an atom. Atoms are tiny particles in the molecules that make up gases, liquids, and solids. Atoms are made up of three particles, called protons, neutrons, and electrons. An atom has a nucleus (or core) containing protons and neutrons, which is surrounded by electrons.
