Experimental diffusion data in the literature were evaluated in order to assess the atomic mobility for the body-centered cubic phase in the U–Pu–Zr system by means of the diffusion-controlled transformation phenomenological treatment. The developed mobility database was validated by comprehensive comparisons made between the experimental and calculated diffusion coefficients, as well as other interesting details resulting from interdiffusion, e.g. the concentration profile and the diffusion path of diffusion couples.
