User Manual for the Total System Model Version 6.0 Preprocessor

The Total System Model Preprocessor (TSMPP) is a part of the Total System Model (TSM),
which is a PC-based simulator that is a decision aid to achieve overall Office of Civilian
Radioactive Waste Management (OCRWM) disposal objectives. The TSMPP combines
information about existing conditions, such as waste inventory estimates and site capabilities,
with projections of future conditions, such as projected waste discharges and expected cask
capabilities, to provide a waste shipment schedule that is input to the TSM. The TSM then uses
this shipment schedule to simulate national transportation and operations at the repository.
The TSMPP databases and logic are largely based on the previous systems analysis methods
implemented in the CRWMS Analysis and Logistics Visually Interactive (CALVIN) model
(BSC 2003a, BSC 2003b). The CALVIN software and databases were reviewed and were
deemed an adequate basis on which to build the TSMPP. The TSMPP was developed primarily
by removing unneeded portions of CALVIN and adding code (programming) to generate cask
load information and shipping dates. Examples of portions that have been removed from
CALVIN are those related to repository operations, cost analyses, Interim Storage Facility (ISF)
usage, and areas the TSM now simulates (like transportation logistics). However, some of the
structures in CALVIN that were used for these functions have been retained to ensure the
TSMPP functions properly and for possible future use.
