NUCLEAR 101: How Does a Nuclear Reactor Work?
Aug 2, 2023 · 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.
Nuclear reactor - Wikipedia
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction.Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion.When a fissile nucleus like uranium-235 or plutonium-239 absorbs a neutron, it splits into lighter nuclei, releasing energy, gamma radiation, and free neutrons, which can induce further fission ...
Nuclear fission - Wikipedia
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.
The Fission Process | MIT Nuclear Reactor Laboratory
When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below). Each time a U-235 nucleus splits, it releases two or three neutrons. Hence, the possibility exists for creating a chain reaction.
The next generation of nuclear reactors is getting more …
Jan 18, 2024 · Nuclear power plants generate electricity via fission reactions, where atoms split apart, releasing energy as heat and radiation. Neutrons released during these splits collide with other atoms...
Nuclear fission | Examples & Process | Britannica
Sep 28, 2024 · nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy.
Nuclear Fission | Definition, Reaction & Examples | nuclear …
Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in the form of gamma rays) and releases a large amount of energy.
Fission Uranium-235 is useful as a reactor fuel because: 1) It will readily absorb a neutron to become the highly unstable isotope U-236. 2) U-236 has a high probability of fission (about 80% of all U-236 atoms will fission). 3) The fission of U-236 releases energy (in the form of heat) which is used to produce high pressure steam
