NUCLEAR 101: How Does a Nuclear Reactor Work?
WebAugust 2, 2023. Office of Nuclear Energy. NUCLEAR 101: How Does a Nuclear Reactor Work? Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.
What is Nuclear Energy? The Science of Nuclear Power | IAEA
Web15 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.
