The choice of material for radioactive waste immobilization depends upon the chemistry of the waste type and the physical environment in which the waste form is to be stored. Apatites are potential candidates for radioactive waste streams containing both Actinides and Halides since this combination of species cannot be adequately stored by typical or commercial methods. The current project uses atomic scale modelling techniques to examine the apatite structure and the solid state transport mechanisms associated with both halide and actinide loss. Once these have been established the modelling will be extended to consider the effect of radiation damage and the influence of an aqueous environment.
