Abstract
Nuclear fuel reprocessing plants contain a wealth of plant monitoring data including material
measurements, process monitoring, administrative procedures, and physical protection elements.
Future facilities are moving in the direction of highly-integrated plant monitoring systems that
make efficient use of the plant data to improve monitoring and reduce costs. The Separations
and Safeguards Performance Model (SSPM) is an analysis tool that is used for modeling
advanced monitoring systems and to determine system response under diversion scenarios. This
report both describes the architecture for such a future monitoring system and present results
under various diversion scenarios. Improvements made in the past year include the development
of statistical tests for detecting material loss, the integration of material balance alarms to
improve physical protection, and the integration of administrative procedures. The SSPM has
been used to demonstrate how advanced instrumentation (as developed in the Material
Protection, Accounting, and Control Technologies campaign) can benefit the overall safeguards
system as well as how all instrumentation is tied into the physical protection system. This
concept has the potential to greatly improve the probability of detection for both abrupt and
protracted diversion of nuclear material.
