Definition of nuclear fission

definition of nuclear fission Nuclear fission in american the splitting of the nuclei of atoms into two fragments of approximately equal mass, accompanied by conversion of part of the mass into energy: the principle of the atomic bomb.

In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into. Nuclear fission noun the splitting of an atomic nucleus into approximately equal parts, either spontaneously or as a result of the impact of a particle usually with an associated release of energy sometimes shortened to: fission compare nuclear fusion. Definition of nuclear fission in us english - a nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of.

1 a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy 2 reproduction of some unicellular organisms by division of the cell into two more or less equal parts. Nuclear fission is a man-made deliberately-produced nuclear reaction, achieved with the help of neutrons and hence unit also follows the same methodology for inducing fission reaction in the fuel atoms filled in a portion of the sub-chamber. Fission definition: fission is defined as the action of dividing into two or more parts (noun) when everyone in your club disagrees on a fundamental issue and you all split up and three separate new clubs are formed, this is an example of fission.

Nuclear fission is a form of alternative energy, that can be utilized in place of fossil fuels that are most commonly used nuclear power plants are the way. Nuclear fission is a reaction in which an atom's nucleus is broken apart, releasing a tremendous amount of energy nuclear fission is used in many power plants on earth (and is used in atomic weapons. Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy. Nuclear fission: 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 n the splitting of an atomic nucleus into approximately equal parts, either spontaneously or as a result of the impact of a particle usually with an associated release of energy , (sometimes shortened to) fission compare → nuclear fusion. Nuclear fission is a method of obtaining energy through nuclear reaction that is based on the partition of the nucleus of atoms usually uranium. Fusion differs from fission, which splits atoms and results in substantial radioactive waste, which is hazardous nuclear fusion is a real possibility, new models suggest. A nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy ionising radiation radiation that ionises substances it passes through.

Other articles where nuclear chain reaction is discussed: chain reaction: nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission. Nuclear fission is the reverse process, where the splitting of atoms occurs by collision atoms are split into smaller nuclei, and essentially become seperate particles such as protons, neutrons and others. 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.

Frisch named the new nuclear process fission after learning that the term binary fission was used by biologists to describe cell division hahn and strassmann published their finding separately, and did not acknowledge meitner's role in the discovery. Nuclear fission the splitting of the nuclei of atoms into two fragments of approximately equal mass, accompanied by conversion of part of the mass into energy: the principle of the atomic bomb nuclear-fission. Nuclear fission definition, meaning, what is nuclear fission: → fission learn more. 1 (also nuclear fission) (physics) the act or process of splitting the nucleus (= central part) of an atom, when a large amount of energy is released compare fusion wordfinder physics amplitude, atom, energy, fission, force, frequency, gravity, molecule, nuclear, physics see related entries: energy and physical forces, the universe.

  • The highspeed neutrons generated by fusion could split apart the u-238 atoms to generate fission, and the fission could generate lots of energy to help maintain the fusion, thus significantly reducing the amount of external energy input, and achieve the complete burning of nuclear fuel to avoid radioactive waste.

A good example of fission is the splitting of a uranium nucleus encyclopaedia britannica/uig / getty images fission is the splitting of an atomic nucleus into two or more lighter nuclei accompanied by energy release the original heavy atom is termed the parent nucleus and the lighter nuclei are. Nuclear fission diagram shows a neutron being absorbed by a uranium nucleus which then becomes unstable and splits into two new atoms with release of energy and some more neutrons nuclear fission is a process used to create energy. Fission occurs spontaneously, generally when a nucleus has an excess of neutrons, resulting in the inability of the strong force to bind the protons and neutrons together the fission reaction used in many nuclear reactors and bombs involves the absorption of neutrons by uranium-235 nuclei, which immediately undergo fission, releasing energy.
