spontaneous nuclear reaction
11Nuclear fuel cycle — The nuclear fuel cycle, also called nuclear fuel chain, is the progression of nuclear fuel through a series of differing stages. It consists of steps in the front end, which are the preparation of the fuel, steps in the service period in which… …
12Nuclear binding energy — is the energy required to split a nucleus of an atom into its component parts. The component parts are neutrons and protons, which are collectively called nucleons. If the binding energy for the products is higher when light nuclei fuse, or when… …
13Spontaneous fission — (SF) is a form of radioactive decay characteristic of very heavy isotopes, and is theoretically possible for any atomic nucleus whose mass is greater than or equal to 100 u (elements near ruthenium). In practice, however, spontaneous fission is… …
14Nuclear reactor physics — See also: Critical mass Nuclear reactor physics is the branch of science that deals with the study and application of chain reaction to induce controlled rate of fission for energy in reactors. Most nuclear reactors use a chain reaction to induce …
15nuclear weapon — an explosive device whose destructive potential derives from the release of energy that accompanies the splitting or combining of atomic nuclei. [1945 50] * * * or atomic weapon or thermonuclear weapon Bomb or other warhead that derives its force …
16Nuclear drip line — In nuclear physics, the boundaries for nuclear particle stability are conceptualized as drip lines. The nuclear landscape is understood by plotting boxes, each of which represents a unique nuclear species, on a graph with the number of neutrons… …
17Nuclear power phase-out — A nuclear power plant at Grafenrheinfeld, Germany. Chancellor Angela Merkel s coalition announced on May 30, 2011, that Germany’s 17 nuclear power stations will be shut down by 2022, in a policy reversal following Japan s Fukushima Daiichi… …
18Nuclear isomer — A nuclear isomer is a metastable state of an atomic nucleus caused by the excitation of one or more of its nucleons (protons or neutrons). Metastable refers to the fact that these excited states have half lives more than 100 to 1000 times the… …
19reaction — noun 1 response ADJECTIVE ▪ extreme, strong, violent ▪ favourable/favorable, positive ▪ adverse, hostile, negative …
20History of nuclear weapons — The history of nuclear weapons chronicles the development of nuclear weapons. Nuclear weapons are devices that possess enormous destructive potential derived from nuclear fission or nuclear fusion reactions. Starting with the scientific… …
