Physical protection of nuclear facilities. Quarterly progress report, October-December 1979
- ed.
All of the activities during the past quarter were related to the facility characterization and evaluation methodology development efforts. The principal facility characterization activities included (1) the vital area analyses of operating reactor facilities, (2) support for studies of the Three Mile Island incident, and (3) the development of importance measures for rank ordering vital areas. Evaluation methodology work concentrated on continued development the Safeguards Automated Facility Evaluation (SAFE) methodology and contractor support related to the Safeguards Network Analysis Procedure (SNAP) application. Vital area analyses were performed on a total of nine boiling water reactors and six pressurized water reactors during the past quarter. Computer codes for the calculation of importance measures for rank ordering vital areas were developed. A user's manual for the SANDIA-ORIGEN computer code, which calculates detailed isotopic composition as a function of time in nuclear reactor fuel irradiation and radioctive decay problems, was published. The SANDIA-ORIGEN computer code has been used to provide calculations of core inventory for Three Mile Island. Work on the SAFE methodology centered on the preparation of documentation for the methodology and the modification to many of the computer codes currently used in or planned for SAFE. Volumes II and III of the SAFE Users Manual are presently being written. Modifications have been made to the Brief Adversary Threat Loss Estimator (BATLE) model, the Adversary Path (ADPATH) routine, the Minimum Detection Probability and Time (MINDPT) code, and the Pathfinding Simulation (PATHS) code.
