Activities this quarter included completion of a major portion of the Standardized Nuclear Unit Power Plant System (SNUPPS) facility characterization. Vital area analysis of a boiling water reactor (BWR) and a benchmark calculation for a pressurized water reactor (PWR) were also completed. Work was initiated this quarter on a computer-based fault tree development program which will hopefully reduce the time and manpower required to translate facility and operational information into fault tree logic. A new computer code, ADPATH, which finds both theft and sabotage paths in a facility digraph and takes into account adversary direction of travel has been developed. Tests designed to fully exercise the theft path capabilities of ADPATH are currently being devised. Preliminary work on an update processor for the BARRIER module of the Safeguards Engineering and Analysis Data-Base (SEAD) was undertaken. Work was also initiated on the development of a library of primitives, including schemas and program modules, that will be used in programs that access SEAD. This library will prevent duplication in software writing for the various SEAD modules. Considerable time was spent this quarter in preparing for a demonstration of the Safeguards Automated Facility Evaluation (SAFE) methodology to Nuclear Regulatory Commission (NRC) staff members and management and the documentation of the SAFE process and related computer codes. Efforts to develop a capability which provides for the automatic identification of regions within SAFE continued. In addition, work was initiated on the development of a SAFE/SEAD interface.
