Caesium and strontium contamination on NAG 18/10L stainless steel following corrosion in simulated nitric acid reprocessing liquor
Source abstract
Abstract
This study investigates the uptake of Cs and Sr contamination into the oxide on NAG 18/10 L stainless steel following corrosion in nitric acid reprocessing simulant. Atom probe tomography results found the uptake of Cs contamination to be localized to the oxide and sub-oxide layers, with no contamination within the metal matrix. A mechanism of Cs uptake via nano-porosity at the metal-oxide interface is proposed. Modelling techniques found that contamination at very low concentration has a significant effect on overall radioactivity.
