Abstract

The Nuclear Materials Identification System (NMIS) with a deuterium-tritium neutron source has been used to image fissile material inside containers to determine geometry This paper investigates the possibility that the NMIS could be used to determine the mass of UO₃ powder of variable shape or density in a container of arbitrary but known shape. The MCNP-PoliMi computer code was used to model measurements of several fill scenarios of a trough-shaped container by the NMIS to estimate how accurately the mass of the UO₃ powder could be determined.
