In 1971 the Harry Diamond Laboratories developed for the US Arms Control and Disarmament Agency a prototype model of a portable safing system that uses fiber optic seals and assembles, photographs, and identifies them in the field. The safing system provides a tamper-resistanttamper-indicating seal that can be nondestructively identified in the field. Such seals are needed for the effective use of containment as a safeguards technique and for the protection of unattended instruments used for surveillance at peaceful nuclear facilities. This report describes an improved fiber optic seal assembly and associated equipment designed to meet these needs. The improved seal assembly uses both a lead filler and a mechanical support to hold the fibers in place. A 30X handheld viewer was designed for convenient direct viewing of the seal fingerprints.
