Trial application of a safeguards performance evaluation methodology for light water reactors

A methodology for evaluating the performance of safeguards implementations under INFCIRC/153 type agreements has been developed and tested using inspection data for nine light water reactor facilities. The methodology makes use of logic programming techniques to allow for both qualitative and quantitative components in the overall assessments. The trial application indicated that the methodology is especially useful as a diagnostic tool, i.e. for pinpointing causes of non-attainment of inspection goals. Routine use would require an efficient interface to IAEA safeguards databases. (author)
