The {sup 252}Cf-source-driven noise analysis method has been suggested as a method of measuring the subcriticality of spent light water reactor (LWR) fuel. A measurement of the subcritical neutron multiplication factor provides the parameter most directly related to criticality safety and can be used to verify the criticality safety margins of spent LWR fuel configurations. Previous measurements by this method have shown large changes in measured coherences for small changes in fissile mass. To explore this systematically, this paper evaluates the sensitivity of these noise analysis measurements to the amount of fission products in spent LWR fuel. This is of interest for validating calculations for burnup credit.
