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
Prompt neutron — In nuclear engineering, a prompt neutron is a neutron immediately emitted by a nuclear fission event, as opposed to a delayed neutron decay which can occur within the same context, emitted by one of the fission products anytime from a few… … 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
