Zero power critical is a condition of nuclear fission reactors that is useful for characterizing the reactor core .. nuclear fission. nuclear fission. reactor. nuclear reactor. A reactor is in the zero power critical state if it is sustaining a stable fission chain reaction with no significant growth or decay in the reaction rate , and at a low enough level that thermal considerations are not important to the reaction .. reactor. nuclear reactor. chain reaction. chain reaction. thermal. thermal. For example , a reactor that can produce gigawatts of heat might be considered zero-power critical when producing 100 watts of heat through a fission chain reaction .. reactor. nuclear reactor. chain reaction. chain reaction. Most nuclear reactors are held at a zero-power critical condition as part of the start-up sequence , to assess the condition of the reactor itself .. reactor. nuclear reactor.
