Abstract
E. I. du Pont de Nemours and Company, prime contractor to the Department of Energy, currently operates three nuclear reactors for defense material production at the Savannah River Plant. A highly successful safeguards intrusion detection and access control system, in compliance with DOE Order 5632.4, has been in operation at the reactor sites since September 1984. This paper describes the three-sensor intrusion detection system and the three-parameter access control system, and it gives the maintenance experience for major system components based upon 6 system years of operation. Mean time between failure rates between 0.7 and 345.6 months have been experienced. Key points to the establishment of a successful maintenance program are discussed.
