Physics-based mathematical-computational models provide an invaluable tool for repository design, performance/safety assessments, site clean-up, and environmental remediation in nuclear spent fuel and high level waste disposal in shallow or deep geological media. The migration of nuclear wastes is controlled by coupled THMC (Thermal-Hydrology-Mechanics-Chemical) processes. This talk presents the development of a series of computational models that fully or partially couple these processes. Demonstrative applications are presented to illustrate the interplay of THMC processes and their implications for radionuclide waste managements.
