Determination of the plutonium content in a spent fuel assembly by passive and active interrogation using a differential die-away instrument

In this paper, we present a novel approach to estimating the total plutonium content in a spent fuel assembly (SFA) that is based on combining information from a passive measurement of the total neutron count rate (PN) of the assayed SFA and a measure of its multiplication. While PN can be measured...
