Advanced Tools for ITER Tritium Plant System Modeling and Design

Abstract

Chemical plant system modeling experience based on the use of largely validated commercial modeling tools such as the Aspen HYSYS is adapted and exploited to develop numeric routines for unitary isotopic operations, including permeation, cold trapping, reversible absorption, and cryogenic distillation, for the ITER tritium plant systems. Model prediction capabilities and isotopic database inputs for first-principle models are discussed. Numeric implementation of the Aspen HYSYS routines are presented.

Notes

^a A unitary operation is the most fundamental step for a whole plant to yield the desired product. It involves a physical or chemical transformation such as, for example, filtration, evaporation, or permeation. Each unit operation follows the same physical laws and therefore may be used in all chemical industries.
