Validation Report for Total System Model Preprocessor Version 6

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 TSM is identified as Level
3, i.e., not Important To Safety (ITS) and not Important To Waste Isolation (ITWI), software in
the Bechtel SAIC Company, LLC (BSC) Controlled Software Report.
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.
