Self-organized criticality — In physics, self organized criticality (SOC) is a property of (classes of) dynamical systems which have a critical point as an attractor. Their macroscopic behaviour thus displays the spatial and/or temporal scale invariance characteristic of the … Wikipedia
Nuclear criticality safety — is a field of nuclear engineering dedicated to the prevention of nuclear and radiation accidents resulting from an inadvertent, self sustaining nuclear chain reaction.[1] Additionally, nuclear criticality safety is concerned with mitigating the… … Wikipedia
Structured criticality — is a property of complex systems whereby small events may trigger larger events due to subtle interdependencies between elements. This often gives rise to a kind of stratified chaos where the general behavior of the system can be modeled on one… … Wikipedia
Failure Mode, Effects, and Criticality Analysis — (FMECA) is an extension of Failure Mode and Effects Analysis (FMEA). In addition to the basic FMEA, it includes a criticality analysis, which is used to chart the probability of failure modes against the severity of their consequences. The result … Wikipedia
Critical mass — This article is about nuclear fission reactions. For other uses, see Critical mass (disambiguation). As part of a re creation of a 1945 criticality accident, a plutonium pit is surrounded by blocks of neutron reflective tungsten carbide. The… … Wikipedia
Nuclear 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 … Wikipedia
nuclear reactor — Physics. reactor (def. 4). Also called nuclear pile. [1940 45] * * * Device that can initiate and control a self sustaining series of nuclear fission reactions. Neutrons released in one fission reaction may strike other heavy nuclei, causing them … Universalium
Nuclear and radiation accidents — This article is about nuclear and radiation accidents in general. For a list of military nuclear accidents, see List of military nuclear accidents. For a list of civilian nuclear accidents, see List of civilian nuclear accidents. For a discussion … Wikipedia
Prompt critical — In nuclear engineering, an assembly is prompt critical if for each nuclear fission event, one or more of the immediate or prompt neutrons released causes an additional fission event. This causes a rapidly exponential increase in the number of… … Wikipedia
Nuclear chain reaction — A possible nuclear fission chain reaction. 1. A uranium 235 atom absorbs a neutron, and fissions into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. 2. One of those neutrons is absorbed by an … Wikipedia
CANDU reactor — The CANDU reactor is a Canadian invented, pressurized heavy water reactor developed initially in the late 1950s and 1960s by a partnership between Atomic Energy of Canada Limited (AECL), the Hydro Electric Power Commission of Ontario (now known… … Wikipedia
