N2 - We present the results of a combination of static and dynamic simulations employing empirical potentials, investigating the structures of dislocations in UO2 and show how the dislocation core structureinfluences the rate of O2- and U4+ diffusion along the dislocation (i.e. pipe diffusion). In the region imme-diately surrounding the dislocations there is a significant reduction in the activation energies and diffu-sion coefficients for O2- and U4+ diffusion, however only out to a cylindrical radius of 20 Å from thedislocation centre. The contribution of pipe diffusion to the overall O2- and U4+ diffusion is also discussed.
