Nuclear fission - Wikipedia Nuclear fission produces energy for nuclear power and drives the explosion of nuclear weapons Both uses are possible because certain substances called nuclear fuels undergo fission when struck by fission neutrons, and in turn emit neutrons when they break apart
Fission and Fusion: What is the Difference? | Department of . . . Fission occurs when a neutron slams into a larger atom, forcing it to excite and split into two smaller atoms—also known as fission products Additional neutrons are also released that can initiate a chain reaction
Nuclear fission | Examples Process | Britannica 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 and Examples - Science Notes and . . . Nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei This process often produces gamma photons and releases a significant amount of energy
Understanding the Difference Between Nuclear Fission and . . . Nuclear fission is the process used in today's nuclear power plants It occurs when the nucleus—the central core of an atom—typically of a heavy element, such as uranium or plutonium, splits into two smaller nuclei
Fission - Understand Energy Learning Hub Nuclear fission is the process of splitting a large atom into two smaller atoms and releasing a LOT of heat, making it an extremely energy dense resource That heat is used to boil water, make steam, turn a turbine and generator, and produce electricity
