Total System Model Version 6.0 Cost Estimating Routines Design and Bases

This manual discusses the cost estimating routines used in Version (V) 6.0 of the Total System
Model (TSM) as described in the TSM User Manual (BSC 2007a). The TSM estimates costs
during the simulation of the Civilian Radioactive Waste Management System (CRWMS)
mission. The TSM is not intended to provide a full Total System Life Cycle Cost (TSLCC)
evaluation tool but focuses on the CRWMS Waste Acceptance, Storage, and Transportation
(WAST) elements reported for the TSLCC in Reference BSC 2003a. This manual also
summarizes the comparison of the results of the TSM to the results in the 2003 TSLCC, which
are contained in the TSM Cost Basis and Check, (BSC 2006a). Reference BSC 2006a compares
the TSM results to the cost results for the 2003 TSLCC because the 2003 TSLCC was
contemporary at the onset of the TSM development and had a comprehensively documented and
checked system analysis.
The TSM Cost Basis and Check, (BSC 2006a) was developed for TSM V4.0 but applies equally
to TSM V5.0 and TSM V6.0 because there have been no major changes to the cost estimating
parts of the TSM. Other changes that could impact cost results are discussed in the TSM User
Manual (BSC 2007a) Section 1.5 and Section 1.5 of this report. There were no unanticipated
impacts on the cost results as addressed in the TSM V6.0 validation report (BSC 2007b).
This manual assumes the reader has a basic knowledge of the TSM functionality and conventions
in the TSM User Manual (BSC 2007a) and this manual must be read in conjunction with the
User Manual.
TSM uses the SimCAD™ process simulation software developed by Create-a-Soft (CaS); more
information on SimCAD™ conventions is in Reference CaS 2006.
