Fissioning Meaning: Definition, Examples, and Translations
⚛️
fissioning
[ˈfɪʃənɪŋ ]
Definition
nuclear physics
Fissioning refers to the process of splitting the nucleus of an atom into two or more smaller nuclei, along with the release of energy and neutrons. This process occurs in nuclear reactors and atomic bombs. When a heavy nucleus, such as Uranium-235 or Plutonium-239, absorbs a neutron, it becomes unstable and splits apart. The fissioning process not only produces significant energy but also creates additional neutrons, which can induce further fission in nearby nuclei, leading to a chain reaction.
Synonyms
division, fragmentation, splitting.
Examples of usage
- The fissioning of uranium fuels the reactor.
- Scientists studied the effects of fissioning in controlled environments.
- Fissioning can lead to an exponential increase in energy production.

Interesting Facts
Science
- Fissioning is a key process in nuclear power generation, where splitting atoms releases a tremendous amount of energy.
- This process can lead to chain reactions, which are used in both reactors and nuclear weapons.
- Uranium-235 and Plutonium-239 are commonly used isotopes in the fissioning process.
Pop Culture
- Fissioning has been featured in various movies, often highlighting its dangerous and powerful nature, such as in 'Godzilla' films.
- In video games like 'Fallout', nuclear fission is a theme reflected in the post-apocalyptic landscape and lore.
- Documentaries and educational programs often explore the concept of fissioning to explain the science behind energy.
History
- The discovery of nuclear fission by scientists Lise Meitner and Otto Hahn in 1938 changed the course of science and warfare.
- Fissioning was utilized in the Manhattan Project during World War II, leading to the development of the atomic bomb.
- The peaceful application of fissioning for energy began in the 1950s, with the first commercial reactor built in the UK.
Environmental Impact
- While nuclear fissioning produces large amounts of energy, it also generates radioactive waste that must be carefully managed.
- Nuclear power plants, which rely on fissioning, have lower carbon emissions compared to fossil fuel-based power generation.
- Public opinion on fissioning is mixed, as it presents both potential benefits in energy sustainability and concerns over safety.
Origin of 'fissioning'
Main points about word origin
- The term comes from the Latin word 'fissionem,' meaning 'a cleaving or splitting.'
- It entered scientific language in the early 20th century, often associated with nuclear physics.
- The word shares roots with 'fissure,' which indicates a crack or split.
The term 'fission' originates from the Latin word 'fissio', meaning 'a cleaving or splitting'. It was first introduced in the early 20th century in the field of nuclear physics to describe the process discovered by scientists Otto Hahn and Fritz Strassmann in 1938, who observed the fission of uranium isotopes. The term became widely known after the development of nuclear weapons and reactors in the following decades. In scientific literature, fissioning is closely associated with the release of massive energy, leading to innovations in both energy generation and weaponry. The understanding and manipulation of fissioning have profoundly impacted modern science and technology, particularly in energy policy and military strategy.
