Abrasive blasting techniques are being developed for canister decontamination. Abrasive blasting with a slurry of frit followed by rinsing with high pressure water is the present reference process. The present reference process was reevaluated, because of equipment design concerns due to the abrasiveness of the slurry, and potential corrosion problems due to possible water intrusion into the canister. The ability of candidate processes to remove radioactive contamination from Type 304L stainless steel specimens has now been quantitatively determined under DWPF conditions. The type of contamination, the amount of contamination, and the heating conditions used spanned the range of conditions expected in the DWPF.
