prompt criticality
The point at which the prompt neutrons produced by a nuclear fission chain reaction…The point at which the prompt neutrons produced by a nuclear fission chain reaction are just sufficient to sustain the chain reaction on their own (the state of being prompt critical); past this point, changes in reaction power are controlled by changes in the prompt neutron flux, and occur on a timeframe of milliseconds, too rapidly to be controlled by mechanical means.
