Title: A posteriori verification and validation of a tritium dispersion and consequence model

Abstract

An American National Standards Institute (ANSI) posteriori (backfit) process, available to provide software quality assurance (SQA) for software developed outside of required qualification protocol, has been applied to the special-purpose, versatile tritium dispersion and consequence model, UFOTRI, a computer model developed at the German Karlsruhe laboratory. UFOTRI was chosen because of its strengths in initial tritium-related consequence analyses and its potential for application in a Department of Energy accident analysis context. The six-task process met key ANSI requirements and was performed during a several-month level of effort. Included project deliverables were Assessment, Test Plan, Configuration Procedure, Error Notification Procedure, Comprehensive Technical Report, and SQA Qualification Report documentation. Comparison to acute release conditions is still in progress, but results to date indicate satisfactory, bounding predictions can be achieved with UFOTRI relative to measurements. Results of this compact effort appear to identify UFOTRI as a suitable candidate for a software toolkit, i.e., minimum verification and validation (V and V) requirements are satisfied, and a configuration controlled version is deemed appropriate for use in a DOE accident analysis context.
