Geologic Waste Disposal and a Model for the Surface Movement of Radionuclides
In the following, a model for the surface movement of radionuclides is presented. This model, which is referred to as the Pathways Model, was constructed at Sandia Laboratories in a project funded by the Nuclear Regulatory Commission to develop a methodology to assess the risk associated with the geologic disposal of high level radioactive waste. The methodology development involves work in two major areas: a) models for physical processes and b) statistical techniques for the use and assessment of these models. The following presentation of the Pathways Model will involve topics from both areas. Additional information on the entire project can be obtained from its interim report (1). The work introduced in this paper is described in greater detail in various referenced technical reports; these reports should be consulted for more detailed information than can be provided here.
