fission — [fish′ən, fizh′ən] n. [L fissio < fissus, pp. of findere, to cleave, split < IE base * bheid , to split > BITE] 1. a splitting apart; division into parts 2. NUCLEAR FISSION 3. Biol. a form of asexual reproduction, found in various simple … English World dictionary
Fission-fragment rocket — The fission fragment rocket is a rocket engine design that directly harnesses hot nuclear fission products for thrust, as opposed to using a separate fluid as working mass. The design can, in theory, produce very high specific impulses while… … Wikipedia
fission — 1. The act of splitting, e.g., amitotic division of a cell or its nucleus. 2. Splitting of the nucleus of an atom. [L. fissio, a cleaving, fr. findo, pp. fissus, to cleave] binary f. simple f. in which the two new cells are approximately equal in … Medical dictionary
Fission fragment reactor — Similar to how the fission fragment rocket produces thrust, a fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing … Wikipedia
Fission sail — The fission sail is a type of spacecraft propulsion proposed by Robert Forward that uses fission fragments to propel a large solar sail like craft. It is similar in concept to the fission fragment rocket in that the fission by products are… … Wikipedia
nuclear fission — fission (def. 2). [1885 90] * * * Division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles. The energy released in the… … Universalium

Gun-type fission weapon — Gun type fission weapons are fission based nuclear weapons whose design assembles their fissile material into a supercritical mass by the use of the gun method: shooting one piece of sub critical material into another. Although this is sometimes… … Wikipedia
Fast fission — is fission that occurs when a heavy atom absorbs a high energy neutron, called a fast neutron, and splits. Most fissionable materials need thermal neutrons, which move slower. Fast reactors vs. thermal reactorsFast neutron reactors use fast… … Wikipedia

Gaseous fission reactor — A gas nuclear reactor (or gas fueled reactor ) limits the only temperature limiting materials in a reactor to the reactor walls. A limitation for conventional nuclear fission reactors is that if the nuclear fuel temperature were to rise too high… … Wikipedia
