Tridimensional analysis of migration of 226Ra through a saturated porous media

Abstract

Transport simulation of radioactive contaminants in fluids through saturated porous media provides a powerful tool to prevent the risk they could represent to the environment. This kind of waste is stored in containers. These containers are collocated in subterranean places for being confined. Proper election of those places requires the appropriate classification according to the properties of the site. This work is presenting the 3D numerical simulation of migration of226 Ra through a tridimensional saturated porous media. The numerical solution is obtained solving the transport equations using Darcy’s approximation for flux in saturated media by finite element method (FEM). The governing equations for this model are described as well as the numerical tool employed. The results are analyzed at different simulation time showing the behavior of the system.
