In-house activities this quarter were principally related to facility characterization or evaluation methodology tasks. Facility characterization activities concentrated on the vital area analyses of operating reactor facilities. Existing computer codes for rank ordering of vital areas were extended by the addition of subroutines to allow calculations of approximations to the importance measures. Several new approximation methods applicable to the vital area ranking techniques were also examined. Evaluation methodology efforts this quarter concerned primarily the Safeguards Automated facility Evaluation (SAFE) methodology and the Brief Adversary Threat Loss Estimator (BATLE) model. In support of a study on design concepts for sabotage protection, the SAFE methodology was applied to the Standardized Nuclear Unit Power Plant System (SNUPPS) facility. Alternative SNUPPS facility designs were also analyzed using SAFE. Documentation of the SAFE methodology is approaching completion. The initial draft of Volume III of the SAFE Users Manual is still being prepared, and new sections are being added. At the request of the NRC, modifications have been made to the new BATLE model, and the model is being refined. A version of BATLE which allows a user to vary combinations of input parameters and study the corresponding simulation results was also completed this quarter. This new BATLE version was used to perform sensitivity studies; the data generated by these sensitivity studies will be included in a forthcoming BATLE user's guide. Work also continued on SEADIF, an interface program which will be used to combine SAFE and the Safeguards Engineering and Analysis Data Base (SEAD).
