Two projects at the Pacific Northwest Laboratory (PNL) have been devoted to development of the capability to provide descriptive details of the Federal Waste Management System (FWMS) and its operating rules for comprehensive system studies. This capability is designed to provide consistency in the selection of the bases and assumptions for System Integration Program studies and related computer modeling activities. The System Description Project has developed a modular system description approach that can be used to quickly prepare specific detailed system descriptions once a study-specific system configuration has been defined. The Operational Scenarios and Assumptions (OSA) Project has developed a menu-driven database system that provides a comprehensive and systematic method for specifying the necessary assumptions and system operating rules for specific system studies. The viability of these capabilities has been demonstrated in a system modeling exercise.
