“…Austenitic 316L stainless steel is a common material for the facilities in spent fuel reprocessing plants, based on the plutonium uranium redox extraction (PUREX) process which recycles U and Pu from the fission product by extraction in the nitric acid solution. 1 Nitric acid whose concentration varies from 3 to 14 M is the main process medium for reprocessing plants based on the PUREX process. 2 The surface of 316L stainless steel is contaminated by fission products during the reprocessing process, which is regarded as radioactive waste.…”

Austenitic 316L stainless steel is usually used as the structural material in spent fuel reprocessing facilities. However, the contamination of fission products from spent fuel (especially Cs and Sr) on the surface of facilities will greatly affect its safe decommissioning. In this study, for the first time, with the combination of characterizations of electrochemistry and laserinduced breakdown spectroscopy with two channels, the corrosion and contamination of 316L stainless steel were analyzed in simulated reprocessing environments with HNO 3 concentrations of 3, 6, 8, and 12 M HNO 3 containing Cs and Sr for 7, 14, 21, 30, and 60 days, respectively. The stability order of the passive film of 316L stainless steel in various environments was 12 M HNO 3 > 8 M HNO 3 > 3 M HNO 3 > 6 M HNO 3 . Combined with other characterization methods, a mechanism was proposed. It was found that SrCO 3 , in the matrix, was the main contaminant in the initial 7 days in all environments due to a large number of holes. Then, the dissolution of contaminated steel surface led to the decrease of contaminant, and recontamination occurred after the repassivation of steel. These findings have significant implications for the development and selection of decontamination technology for the contaminated facilities made of 316L stainless steel.
