Harish Gadey, Caitlin Condon, Steven Maheras, Kacey McGee

TL;DR
This paper reports on the verification and validation of the START tool, a geospatial decision-support system for radioactive material transportation, ensuring its accuracy in route length calculations and output reliability.
Contribution
It develops V&V methodologies for START, compares different versions, and assesses the accuracy of route length outputs for radioactive transportation planning.
Findings
START's total length outputs are consistent with geodesic calculations.
Over 150 route pairs tested to validate tool functionality.
Comparison shows improvements from previous START version.
Abstract
The United States Department of Energy (U.S. DOE) is planning for the transportation, storage, and disposal of spent nuclear fuel (SNF) and high-level radioactive waste (HLW) from commercial nuclear power plants and other U.S. DOE sites. The Stakeholder Tool for Assessing Radioactive Transportation (START) is a web-based, geospatial decision-support tool developed for evaluating routing options and other aspects of transporting SNF and HLW via barge, train, truck, and intermodal surface transport in the continental United States. The verification and validation (V&V) effort is intended to independently assess START to provide confidence in the ability of the tool to accurately provide intended outputs. The results selected for the V&V effort of the START code include those identified as crucial outputs by subject matter experts. Outputs from START such as shape files and keyhole…
