A regenerative process involving the use of a dilute solution of nitric (0.5 to 1.0 wt%) and hydrofluoric (0.05 wt%) acids was developed for decontaminating stainless steels (Type 304) to release limits. The solution is regenerated using a strong acid cation exchanger and may eventually be disposed of after processing through a strong base anion exchanger. The waste management aspect of the decontamination is thus limited to the disposal of relatively small volumes of spent cation and anion exchange resins. Application of the acidic reagent for 1 hat 95°C to the tray surfaces of an obsolete irradiated fuel storage basket from Pickering Nuclear Generating Station resulted in the removal of metal exceeding 1 µm and a residual (β,γ) contamination below a target limit of 0.1 µCi/m2. A soak tank system with associated purification, vapor handling, and auxiliary systems is proposed for performing full-scale decontaminations of the baskets.
