Title: Numerical Techniques for Radioactive Waste Repository Safety Assessment Based on Transport in Geological Media Models - 12083

Abstract

Radionuclide migration in geological media is considered within the framework of safety assessment of radioactive waste disposal facility. In this context groundwater flow and transport models are necessary. Computational technologies allowing for semiautomatic generation of unstructured meshes with different cell types, i.e. tetrahedra, hexahedra and pyramids and the subsequent solution of groundwater flow problems on these meshes are introduced. The application of methods is demonstrated in the groundwater flow model for a decommissioned subsurface reactor vessel, buried on its current location. (authors)
