Corrosion Behaviour Of Dwpf Glasses

In this paper the authors analyzed the corroded surfaces of reference glasses developed for the Defense Waste Processing Facility (DWPF) to characterize their corrosion behaviour. The corrosion mechanism of nuclear waste glasses must be known to provide source terms describing radionuclide release for performance assessment calculations. Different DWPF reference glasses were corroded under conditions that highlighted various aspects of the corrosion process and led to different extents of corrosion. The glasses corroded by similar mechanisms and a phenomenological description of their corrosion behaviour are presented.
