“…The Coincidence Collar has been modified for FBR and LWR MOX fuel assembly assay by replacing the americium/Iithium neutron source with a fourth detector bank to give symmetry to the detection efficiency. Figure 45 This general approach has been investigated previously by Close and Krick 74 for FBR subassemblies and Lee and Lindquist 75 for spent PWR fuel assemblies underwater. The present work has an important dif¬ ference in that neutron coincidence counting is used rather than singles counting.…”

From August 1981 through January 1982, the Los Alamos Safeguards and Security Program was involved in many activities that are described in the four parts of this report: Nuclear Facility Safeguards Support, Security Development and Support, Safeguards Technology Development, and International Support. Part 1 covers those efforts of direct assistance to the Department of Energy (DOE) and the Nuclear Regulatory Commission licensee facilities. This assistance varies from consultation on materials accounting problems, through development of specialized techniques and devices, to comprehensive participation in the design and implementation of advanced safeguards systems. In addition, a series of training courses in various aspects of safeguards helps make the technology more accessible to those who must apply it. Part 2 concerns a relatively new set of activities at Los Alamos aimed at the security of information and computer systems. The focus this period has been on furthering the development of the Computer Security Center, which provides the basis for encourag¬ ing and disseminating the emerging technology. Part 3 describes the development efforts that are essential to continued improvements in the practice of safeguards. Although these projects are properly classified as developmental, in every case they are directed ultimately at recognized problems that commonly occur in operating facilities. Finally, Part 4 covers international safeguards activities, including both support to the International Atomic Energy Agency and bilateral exchanges. In addition, enrichment plant safeguards, especially those concerning the Gaseous Centrifuge Enrichment Plant, required a significant portion of our resources. These efforts are beginning to provide substantial returns on our investment in technology transfer. Not only has the level of safeguards effectiveness been increased, but we also are receiving the benefits of field experience in operating environments. Most projects described here were sponsored by the DOE Office of Safeguards and Security. However, safeguards activities that have other sponsors also are reported.
