Abstract
A study was performed for the United States Nuclear Regulatory Commission to determine whether existing process monitoring data recorded by licensees can be used in conjunction with present material accounting systems to increase the effectiveness of safeguarding special nuclear materials. Two licensed fuel fabrication facilities were examined. The results show that significant improvements are obtainable in timeliness of loss detection, mass sensitivity for loss detection, and localization of detected loss to specific materials by the utilization of process monitoring data. The cost for implementation to obtain these improvements is nominal because the measurements already exist.
