Next generation Purex modeling by way of parallel processing with high performance computers
The Plutonium and Uranium Extraction (Purex) process is the predominant method used worldwide for solvent extraction in reprocessing spent nuclear fuels. Proper flowsheet design has a significant impact on the character of the process waste. Past Purex flowsheet modeling has been based on equilibrium conditions. It can be shown for the Purex process that optimum separation does not necessarily occur at equilibrium conditions. The next generation Purex flowsheet models should incorporate the fundamental diffusion and chemical kinetic processes required to study time-dependent behavior. Use of parallel processing with high-performance computers will permit transient multistage and multispecies design calculations based on mass transfer with simultaneous chemical reaction models. This paper presents an applicable mass transfer with chemical reaction model for the Purex system and presents a parallel processing solution methodology.
