User Manual for the Total System Model Version 6.0

The Civilian Radioactive Waste Management System (CRWMS) Total System Model (TSM), a
Level 3 software, is a planning tool that estimates the logistic and cost impacts of various
operational assumptions in accepting radioactive wastes. Waste forms currently tracked are
commercial spent nuclear fuel (CSNF), Department of Energy (DOE) spent nuclear fuel (DOE
SNF), Naval SNF, and high-level (radioactive) waste (HLW). The TSM simulates the actions for
Waste Acceptance (WA) from discharge to emplacement.
The TSM is a Personal Computer (PC)-based, user-friendly, systems model that provides easy to
understand Graphical User Interface (GUI) with dynamic simulation screens to serve as a
decision aid for overall Office of Civilian Radioactive Waste Management (OCRWM) disposal
objectives. The TSM is:
• a real-time process simulation model that achieves the established requirements and provides
a rapid means to evaluate alternative approaches to achieve program and project goals,
• based on established process optimization tools and methods, usability and accepted system
analysis techniques; and
• an end-to-end model with interaction of WA, transportation, and repository parameters and
constraints.
As shown in Figure 1, the functional design of the TSM is to integrate the elements of the
CRWMS mission. Figure 1 shows the functions after complete development. Currently most,
but not all, of the systems analysis results are implemented.
The TSM described in this version of this manual is TSM Version 6.0. Version 6.0 is based on
enhancements and revisions made to the previous TSM Version 5.0 and implements the so-called
Critical Decision (CD) -1 design for the Geologic Repository Operations Area (GROA). Section
1.5 describes the major changes for TSM Version 6.0. See Section 1.5 for a description of the
changes.
