Development of an advanced safeguards system as a proliferation deterrent. [Computerized control; physical protection; safeguards coordination]
The Advanced Safeguards System consists of Computerized Nuclear Materials Control and Accounting System, Physical Protection System, and Safeguards Coordination Center (SCC). Should all the computer-based monitoring systems be overcome (i.e., the NMC computer programmed not to recognize a materials inventory change, the SCC computer programmed to accept a falsified area and personnel authorization, and the physical security system programmed not to alarm for area intrusion), the requirements of the physical security system remain formidable barriers to successful theft since all SNM is separated from the uncontrolled areas by at least one entry control portal. An egress from the protected area--by either a vehicle through the vehicle access portal, or on foot through the personnel access portal--requires that the individuals be subjected to a search for metal and SNM before egress is permitted. The material access areas are further controlled by an interior access portal imposing the same SNM and metal search criteria. The portal search criteria are not subject to computer interpretation, but direct positive--negative indications to the portal patrolman. The physical security system then provides an independent backup should the computerized systems be defeated. Thus, the computer systems themselves will not, if defeated, guarantee an adversary success. The corollary also holds true; a defeat of the physical search elements of the physical security system will not guarantee adversary success because of the monitoring/surveillance function of the computerized systems. The complementary and overlapping nature of the safeguards systems is intended to provide multiple layers of safeguards, each layer providing an effective element of protection. Tests to date indicate that it appears feasible to meet operational objectives and maintain a high safeguards performance level using these concepts which are being incorporated into the Advanced Safeguards System.None
