Numerical Modeling of Rock Stresses within a Basaltic Nuclear Waste Repository. Annual Report for Fiscal Year 1979

摘要

The work entailed thermomechanical and fluid-flow modeling in both the development of such models and in their application to a preconceptual repository design and the Near-Surface Test Facility. The present numerical models available at University of Minnesota and Dames and Moore are summarized. Areas in which further code development are required have been identified as discontinuum models, the discrete element method, and fluid-flow models. The applicability of the various numerical models are also described and their areas of application delineated. Analyses of the preconceptual repository layout and the Near-Surface Test Facility test program are presented. (ERA citation 06:005820)
