Neutron resonance densitometry (NRD) has been proposed to quantify nuclear materials in particle-like debris of melted spent nuclear fuel formed in severe nuclear reactor accidents. NRD proposed here is a hybrid of neutron resonance transmission analysis and neutron resonance capture analysis using a pulsed neutron generator and the neutron time-of-flight technique. In this study, the effects of impurities and sample thickness on the measurement statistical uncertainty were examined using a linear absorption model.
