  • Groundwater flow and radionuclide transport in fault zones in granitic rock

    Creator:
    Geier, Joel E.
    Abstract:
    Fault zones are potential paths for release of radioactive nuclides from radioactive-waste repositories in granitic rock. This research considers detailed maps of en echelon fault zones at two sites in southern Sweden, as a basis for analyses of how their internal geometry can influence groundwater flow and transport of radioactive...

  • Diffusion of selected radionuclides through Hanford Trench 8 soil material

    Creator:
    Schwab, Kristen E.
    Abstract:
    Shallow land burial in vadose zone sediment at the Hanford Site in Washington is being considered for the disposal of Category 3 low-level waste. A series of column experiments were conducted to evaluate and model the performance of the soil surrounding the trench encasement material for iodine-129 and technetium-99 by...

  • Indirect parameter identification algorithm in radial coordinates for a porous medium

    Creator:
    Roley, Kenneth L.
    Abstract:
    The decision to bury high level nuclear wastes in deep geological formations led to the study of the Hanford Nuclear Reservation as one of three possible sites for the first nuclear waste repository in the United States. To adequately evaluate the environmental impact of siting nuclear waste repositories in basalt...

  • Analysis of Carbon-14 Transport from a Contaminated Groundwater Source

    Creator:
    Napier, Jonathan Bamberger
    Abstract:
    Radioecology observes the movement of radioactive isotopes throughout the environment. For radioecology, locations of study are limited to areas accidentally contaminated from a number of sources. The Chalk River Laboratories of Atomic Energy of Canada Limited have stored low level waste since the mid 1940s. In certain instances, the wastes...
