Book Description

A study was conducted for the United States Nuclear Regulatory Commission as part of a continuing program to estimate the effectiveness of using process monitoring data to enhance special nuclear material accounting in nuclear facilities. Two licensed fuel fabrication facilities with internal scrap recovery processes were examined. The loss detection sensitivity, timeliness and localization capabilities of the process monitoring technique were evaluated for single and multiple (trickle) losses. The impact of records manipulation, mass and isotopic substitution, and collusion between two insiders as methods for concealing diversion were also studied.
