Diffusion characteristics of U(IV) and Pu(III) ions in eutectic melts LiF-NaF and LiF-CaF2 according to molecular dynamics calculations

The diffusion characteristics of U(IV) and Pu(III) ions in model melts 66LiF-44NaF at 1000–1600 K and 80LiF-20CaF2 at 1050–1600 K have been calculated by the molecular dynamics method. The diffusion activation energies of U(IV) and Pu(III) ions in the these melts have been calculated.
