Diffusion of soluble materials in a fluid filling a porous medium
- 1. Aktiebolaget Atomenergi, Studsvik (Sweden)
Description
The physical and mathematical foundations of diffusion in porous media are explained. Equations for diffusion of a radioactive nuclide chain are derived. The program DIWA for computing one-dimensional diffusion of one nuclide is described and results from such calculations are given. An underground deposition of wastes was assumed at a deep of 500 m. For a pessimistic assumption about the diffusion coefficient, no decay and no adsorption, the discharge at the ground level was negligible for at least 70000 years. (author)
