- Abstract
The safeguardability of an advanced nuclear energy system can be achieved by implementing International Atomic Energy Agency safeguards at the initial facility design stages. In a companion paper (see page 4), a high-reliability safeguards (HRS) approach was introduced, where an envelope of functional components was proposed as part of a design strategy for a remotely handled fuel fabrication facility. Discussion was then based on a commercial pyroprocessing facility as an ex-ample system. The functional components are intended to be flexible and adaptable for various conceptual designs. Here, the HRS methodology is further developed by considering how safeguardability can be integrated into a licensing approach. Primarily, within this context, then, a risk-informed, performance based-framework is qualitatively discussed. Potential initiators of diversion strategies that could arise from similar classes of events as that of safety and physical security are identified and their frequency of occurrence are formulated. This can then be utilized to assess system components by quantifying a licensing envelope that will encompass a spectrum of initiating events ranging from low-frequency normal operational occurrences to higher-frequency off-normal and security-related events that also challenge physical protection of the facility. The consequence of which, for safeguards, would be the probability of a false alarm or false positive anomaly. This framework is adaptable for incorporating additional engineering experience as it becomes available, and should also be applicable to similar remotely-handled facilities.
