REDUNDANT AND INDEPENDENT CONTAINMENT AND SURVEILLANCE SYSTEMS

Facilities which contain large amounts of nuclear material and facilities where the nuclear material is difficult to access are now coming under safeguards. In these facilities, material reverification is very difficult, intrusive and costly. It should be possible, in many of these cases, to use redundant and independent containment and surveillance (C/S) systems to lower the need for remeasurement of such inventories. This paper examines the concept of redundant and independent C/S systems, and discusses how these systems could potentially be applied. Improvement in the a s s u r a n c e of continuity of safeguards information through the use of redundant and independent C/S systems is discussed. Equipment which could be used in such systems and an example of a potential system are presented.
