Abstract
The Department of Energy (DOE) has begun several efforts to assess the performance of its safeguards and security systems at its various facilities, including the Master Safeguards and Security Agreements. (MSSA's) and the Material Control and Accountability (MC&A) performance requirements. In order for these new programs to be valid, it is necessary to have meaningful and realistic values associated with the detection capabilities of the various components of the safeguards and security systems. It is important to identify the various methodologies that might be applicable to the assortment of detection elements and for the facility to allocate its resources available for quantification of detection elements in a manner that would yield the highest quality assessment for their overall systems. There are four primary ways to quantify the individual detection elements: 1) the development of complex-wide standards such that the probability values can be adjusted for each Site based on differences from the standard, 2) performance testing of .individual elements, 3) the use of statistical calculations or by performing simulations, or 4) the use of expert judgment to assign a categorical value (e.g,, high, medium, or low) supported by a limited number of performance tests to support a statistical test of hypothesis.
