Characterizing the Evolution of the In-Drift Environment in a Proposed Yucca Mountain Repository

PDF Version Also Available for Download.

Description

This presentation provides a high-level summary of the approach taken to achieve a conceptual understanding of the chemical environments likely to exist in the proposed Yucca Mountain repository after the permanent closure of the facility. That conceptual understanding was then made quantitative through laboratory and modeling studies. This summary gives an overview of the in-drift chemical environment modeling that was needed to evaluate a Yucca Mountain repository: it describes the geological, hydrological, and geochemical aspects of the chemistry of water contacting engineered barriers and includes a summary of the technical basis that supports the integration of this information into the ... continued below

Description

This presentation provides a high-level summary of the approach taken to achieve a conceptual understanding of the chemical environments likely to exist in the proposed Yucca Mountain repository after the permanent closure of the facility. That conceptual understanding was then made quantitative through laboratory and modeling studies. This summary gives an overview of the in-drift chemical environment modeling that was needed to evaluate a Yucca Mountain repository: it describes the geological, hydrological, and geochemical aspects of the chemistry of water contacting engineered barriers and includes a summary of the technical basis that supports the integration of this information into the total system performance assessment. In addition, it presents a description of some of the most important data and processes influencing the in-drift environment, and describes how data and parameter uncertainty are propagated through the modeling. Sources of data include: (1) external studies regarding climate changes; (2) site-specific studies of the structure of the mountain and the properties of its rock layers; (3) properties of dust in the mountain and investigations of the potential for deliquescence on that dust to create solutions above the boiling point of water; (4) obtaining thermal data from a comprehensive thermal test addressing coupled processes; and (5) modeling the evolution of the in-drift environment at several scales. Model validation is also briefly addressed.
