Contaminant transport results are summarized for significant radionuclides that are hypothetically released to the accessible environment and to the biosphere. After the radionuclide concentrations are mathematically introduced into the ground-water movement patterns, waste movement patterns are outlined over elapsed time. (The Geologic Simulation Model can also be used to forecast future boundary conditions for the hydrologic simulation.) Chemical reactivity of the basalt with ground water will influence the leaching and transport of radionuclides solubility more » equilibria based on available data are estimated with geochemical models. Hypothetical release scenarios have been developed and evaluated by a process involving expert opinion and a Geologic Simulation Model for basalt. Regional and local ground-water movement patterns have been defined with the aid of hydrologic computer models. Because an understanding of the dynamics of ground-water flow is essential to the development of release scenarios and consequence analyses, a key step in the demonstration is the systems characterization contained in the conceptual model. A simplified diagram of the AEGIS analyses is shown. Available information has been used to establish the data base and initial hydrologic and geologic interpretations for this site-specific application. The following report documents the technology demonstration in basalt.
Published hydrologic and geologic data used in the analyses were gathered in 1979 or earlier. Hypothetical repository coordinates were selected for an actual geographical setting on the Hanford Reservation in the state of Washington. A technology demonstration of current performance assessment techniques as applied to a nuclear waste repository in the Columbia Plateau Basalts was conducted.
