Abstract

pulsed neutron interrogation measurements have been performed on highly enriched uranium (heu) oxide fuel pins and depleted uranium (du) metal using a d-d neutron generator (2xl0 ⁶ neutrons-s ^-1) and moderated ³he tubes at the idaho national laboratory power burst facility. These measurements demonstrate the ability to distinguish heu from du by coincidence counting using a pulsed source. The amount of heu measured was 8 kg in a sealed 55-gallon drum compared to 31 kg of du. Neutron events were counted during and after the pulse with the nuclear materials identification system (nmis) and used to calculate the neutron coincidence time distributions. Passive measurements were also performed for comparison with the pulsed measurements. This paper presents the neutron coincidence time distribution and feynman variance results from the measurements.
