(621f) Design and Implementation of the Ustc-Solvex Application for Uranium Solvent Extraction

This presentation will cover the design and implementation of a parallel network-based simulation approach for solvent extraction of interest to non-irradiated uranium processing. This development supports the modeling and simulation efforts of the ORNL Uranium Science & Technology Center. Usecases aimed at progressively developing a general capability for transient, non-equilibrium solvent extraction simulation will be covered. Including tri-butyl phosphate extraction of water, nitric acid, and uranyl nitrate from the aqueous phase. Flexibility for incorporating various reaction mechanisms involving multiple phases will be demonstrated. Automated features such as stage efficiency, vapor phase humidity, and AI LLM reporting and analysis will be discussed. Finally implementation of parameter variation will be described with some examples.
