fission material
11Gun-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… …
12Nuclear fusion-fission hybrid — Hybrid nuclear fusion fission (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s …
13Boosted fission weapon — A boosted fission weapon usually refers to a type of nuclear bomb that uses a small amount of fusion fuel to increase the rate, and thus yield, of a fission reaction. The neutrons released by the fusion reactions add to the neutrons released in… …
14Nuclear fission product — Nuclear fission products are the atomic fragments left after a large atomic nucleus fissions. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons and a large release of energy… …
15Fertile material — is a term used to describe nuclides which generally themselves do not undergo induced fission (fissionable by thermal neutrons) but from which fissile material is generated by neutron absorption and subsequent nuclei conversions. Fertile… …
16Long-lived fission product — Long lived fission products are radioactive materials with a long half life (more than 200,000 years) produced by nuclear fission. Contents 1 Evolution of radioactivity in nuclear waste 1.1 Short term 1.2 Medium lived fission products …
17Nuclear material — This article is about the materials. For parts of the nucleus, see atomic nucleus. Nuclear material refers to the metals uranium, plutonium, and thorium, in any form, according to the IAEA. This is differentiated further into source material ,… …
18Geometric and material buckling — In a nuclear reactor, criticality is achieved when the rate of neutron production is equal to the rate of neutron losses, including both neutron absorption and neutron leakage. Geometric buckling is a measure of neutron leakage, while material… …
19Binary fission — is the form of asexual reproduction and cell division used by prokaryotic organisms (such as bacteria or archea). This process results in the reproduction of a living prokaryotic cell by division into two parts which each have the potential to… …
20binary fission — Biol. fission into two organisms approximately equal in size. Cf. multiple fission. [1895 1900] * * * ▪ cell division asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism… …
