Nuclear fission - Wikipedia
WebNuclear 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. Nuclear fission was discovered on 19 December 1938 in Berlin by German chemists Otto Hahn …
Fission and Fusion: What is the Difference? - Department of Energy
WebApr 1, 2021 · Fission and fusion are two physical processes that produce massive amounts of energy from atoms. They yield millions of times more energy than other sources through nuclear reactions. You can check out the difference between the two in this video below.
Nuclear fission | Examples & Process | Britannica
WebApr 9, 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 may take place spontaneously or may be induced by the excitation of the nucleus.
DOE Explains...Nuclear Fission | Department of Energy
WebNuclear fission is the process where the nucleus of an atom splits into two or more smaller nuclei and other particles. These particles can include neutrons, alpha particles (helium nuclei), beta particles ( electrons ), and gamma rays (which consist of particles of light, or photons ).
What is nuclear fission? | Space
WebSep 21, 2022 · Fission is a form of nuclear transmutation, meaning that the starting atoms are not the same elements as the resultant — or daughter — product atoms. The fission process can occur ...
What is fission? | Live Science
WebJul 19, 2023 · Fission is the process by which an atom splits into two, generating two smaller atoms and a tremendous amount of energy. Fission powers nuclear bombs and power plants.
Fundamentals of the fission process - Encyclopedia Britannica
WebFission can be induced by exciting the nucleus to an energy equal to or greater than that of the barrier. This can be done by gamma-ray excitation ( photofission ) or through excitation of the nucleus by the capture of a neutron , proton , …
Nuclear Fission | Understand Energy Learning Hub
WebForm of Energy: Nuclear. Nuclear fission is the process of splitting a large atom into two smaller atoms and releasing a LOT of heat. That heat is used to boil water, make steam, turn a turbine and generator, and produce electricity. Most nuclear power plants today are fueled by enriched uranium 235 to produce non-renewable, carbon-free, 24/7 ...
22.4 Nuclear Fission and Fusion - Physics | OpenStax
WebHundreds of nuclear fission power plants around the world attest to the fact that controlled fission is both practical and economical. Given growing concerns over global warming, nuclear power is often seen as a viable alternative to energy derived from fossil fuels.
Nuclear fission - Fission theory | Britannica
WebNuclear fission is a complex process that involves the rearrangement of hundreds of nucleons in a single nucleus to produce two separate nuclei. A complete theoretical understanding of this reaction would require a detailed knowledge of the forces involved in the motion of each of the nucleons through the process.
