The 252Cf-source-driven neutron noise analysis method for obtaining the subcritical neutron multiplication factor keff of a configuration of fissile material from cross-power spectral densities (CPSDs) was developed to avoid difficulties inherent in other subcriticality measurement methods. These difficulties include a need for a calibration at a known reactivity condition near delayed critical and a dependence on detection efficiency that may be more dependent on the configuration of fissile material than keff. This method has promise for in-plant applications as has been demonstrated in /approximately/20 experiments with a wide variety of fissile material configurations.
