VISA: A Method for Evaluating the Performance of Integrated Safeguards Systems at Nuclear Facilities. Volume II. Appendices.

摘要

This is the second volume of a two volume report on the VISA method for evaluating safeguards at fixed-site facilities. This volume contains appendices that support the description of the VISA concept and the initial working version of the method, VISA-1,presented in Volume I. The information is separated into four appendices,each describing details of one of the four analysis modules that comprise the analysis sections of the method. The first appendix discusses Path Analysis methodology,applies it to a Model Fuel Facility,and describes the computer codes that are being used. The second appendix deals with Detection Analysis,specifically the schemes used in VISA-1for classifying adversaries and the methods proposed for evaluating individual detection mechanisms in order to build the data base required for detection analysis. The third appendix describes the Containment Analysis overt-segment path ranking,the Monte Carlo engagement model,the network simulation code,the delay mechanism data base,and the results of a sensitivity analysis. The last appendix presents general equations used in Interruption Analysis for combining covert-overt segments and compares them with equations given in Volume I,Chapter 3.
