Overview of the integrated vulnerability assessment tool
Safeguards professionals need a single, comprehensive tool for evaluating safeguards effectiveness against theft of special nuclear material by many different adversaries: insiders, outsiders, and colluding insiders and outsiders. This paper describes a new integrated vulnerability assessment tool which is currently being tested and will be ready for release later this year. The tool consist of five modules: Integration System Manager, Facility Description, Insider Evaluation, Outsider Evaluation, and Collusion Evaluation. The Integration System Manager is designed to keep track of analyses completed and in progress, while the Facility Description Module allows the use to describe the facility targets and safeguards components. Information gathered by the Facility Description Module can then be used by the three evaluation modules. The Outsider Evaluation Module is an enhanced version of SAVI (Systematic Analysis of Vulnerability to Intrusion) that includes an expanded outsider threat spectrum, a faster path algorithm, and a neutralization model based on BATLE (Brief Adversary Threat Loss Estimator). The Insider Evaluation Module is based on a new model, and it includes extensive databases for adversary attributes and strategies; it also contains a reference detection database. Insider/Outsider Collusion will be limited to ''hand-off'' scenarios. This tool will provide a standard approach for evaluating safeguards effectiveness and for preparing Master Safeguards and Security Agreements at various DOE facilities. 5 refs., 4 figs.
