Discrepancies in accounting for Special Nuclear Material (SNM) require quick and accurate resolution. The ability to make a definitive resolution often depends on the types of measurement data available and on the way records are maintained in the Material control and Accounting (MC and A) system. An approach is presented for systematically evaluating the overall anomaly detection and resolution capability of an MC and A system. The approach begins with a detailed specification of the material process cycle including all authorized material locations, possible unauthorized locations, and the procedures for measuring and recording movement between locations. The analysis proceeds by identifying the types of errors that could logically occur in the measurement and recording system and estimating their frequency. In this paper a method is described for quantifying the detection capability and resolution effectiveness for each possible error. A new metric is also proposed for quantifying the overall effectiveness of the MC and A system.
