Abstract
A system for determining whether a self-sustaining neutron chain reaction (i.e., criticality) may occur as each successive nuclear fuel element is added to a liquid-filled tank. This is accomplished by determining whether a multiplication factor, k, approaches unity after each element is added to the tank in accordance with the equation: CR=(.alpha.S)/(1-k) where: S is the emission rate of the neutron source; .alpha. is a term that reflects the detector sensitivity as well as the attenuation of the neutron between source and detector and various geometric considerations in the tank; CR is the counting rate from a neutron detector; and k is a multiplication factor of the assembly at any given time for any given element configuration.
