The reduced frequency unannounced verification model

The quantification of inspection randomization models within the context of international safeguards is extended to include the possibility of false alarms associated with measurement errors. Results are used to refine a fuel cycle approach based on randomization of verification across nuclear facilities (the reduced frequency unannounced verification model). Earlier conclusions regarding the usefulness of the model as a means to conserve inspection resources and to reduce safeguards intrusiveness are confirmed.
