Abstract
Radionuclide retardation by geochemical processes is a potentially favorable natural condition of the Yucca Mountain site, the candidate site for the nations`s first Mined Geologic Disposal System for high-level, radioactive waste. The extent to which geochemical processes can be used in the evaluation of alternative conceptual models for the Yucca Mountain site and relied upon as barriers in a multibarrier concept for the isolation of waste is evaluated. A comprehensive geochemical investigation of the Yucca Mountain site is planned. The investigation comprises mineralogic characterization, rock/water interaction, radionuclide solubility, sorption, dynamic transport (diffusion, dispersion, sorption kinetics, diffusive/advective coupling), and integrated transport modeling studies.
