In this work we calculate the Uranium diffusion coefficient in Aluminium fcc lattice. For this purpose we use both, the non-equilibrium thermodynamic and the kinetic theory of isothermal process. Assuming an attractive solute-vacancy interaction, the kinetic equations, the full set of phenomenological Onsager coefficients and the diffusion coefficients are expressed in terms of five-frequencies, which are numerically calculated using the Monomer method.
