Abstract

A comparison of the characteristics of the Nuclear Materials Identification System (NMIS) and its more fieldable version that was developed for future treaty applications, the Fieldable Nuclear Materials Identification System (FNMIS), is presented. Both systems were developed for the US Department of Energy (DOE) Office of Nuclear Verification (ONV). Under the Warhead Safety and Security Exchange Agreement, NMIS was also jointly developed with the Russian Federation. The configuration of the systems and their characteristics are described. In addition, the capabilities, advantages and disadvantages, and a comparison fast-neutron transmission imaging measurement is presented. The comparison measurements gave essentially the same results because the software and imaging apparatus have the same capabilities, with the FNMIS completing the measurements slightly faster. NMIS is an open system that is more easily modified for research applications and is not suitable for the ONV mission, and FNMIS is compatible with an information barrier, which is more useful for ONV applications.
