Designing IAEA safeguards approaches

In the definition of IAEA safeguards objectives, terms such as significant quantities, timely detection and risk of detection are used; these have to be ''translated'' into detection goals so that safeguards can be applied in a systematic and effective manner. These detection goals are not requirements but serve as guidelines for the development of safeguards approaches applicable to generic types of nuclear facilities; they take into account the design and operating practices of such facilities, as well as the technical capabilities of safeguards measures. Approaches have been developed for, and are implemented at, item facilities and small bulk handling facilities. Studies of methods to safeguard the large bulk handling facilities of the future are underway and may lead to different design principles and approaches. 2 refs
