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
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
每日一词：核裂变与核聚变（Nuclear fission and fusion） - 知乎 Nuclear fission occurs when a heavy atomic nucleus splits into two, with the release of energy Nuclei are made up of protons and neutrons, but the mass of a nucleus is always less than the sum of the individual masses of the protons and neutrons inside
Fission and Fusion: What is the Difference? - Department of Energy 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
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
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 MIT Research Reactor is used primarily for the production of neutrons
