This paper presents a numerical modeling for diffusion of nuclide in porous media. This modeling takes Darcy’s Law (hydro field) into account, and the porous media is treated as being isotropic. To simplify the complex coupled issue, we assume the temperature field is isotropic and stable and mechanical field is stable, and then we can get the governing equations of diffusion process. With FEM method, we get the result from our modeling. To validate the modeling, we use COMSOL
®
to repeat the whole process, the results from our modeling and COMSOL
®
are compared in figure. We can see that our modeling is satisfying.
