“…These parameters are related to the plasma state and signal quality, determined after several debugging, in order to detect the target elements. 12,28 For the accuracy of LIBS data, each sample was duplicated three times in different regions, and combined with the report of the previous study, 3,29 on the steel surface were observed by the field emission SEM performed on a JEOL 7800F coupled with an EDS. The AFM (Bruker INNOVA) was used to determine the evolution of surface roughness of steels during contamination.…”

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.

“…Note that the detection limit depends on the sample volume introduced on the surface of the sleeve. However, considering a contaminant ( 90 Sr) on the metallic material in a reactor, [25][26][27] a sensitivitiy enhancement to the ppb (μg L -1 ) order is needed by optimizing operating conditions of the plasma jet and an optical configuration (e.g., the geometric arrangement of the inlet, the lenses, and the detector).…”

Isotope analysis is challenging because spectral resolution is reduced in high-temperature plasma. In this study, a method involving Lamb-dip laser-induced fluorescence spectroscopy combined with a supersonic plasma jet was developed for the detection of strontium (Sr) isotopes. This newly developed system, with a counter-propagating laser configuration to provide an incident laser beam intensity of 61.8 mW mm −2 , selectively detected the Lamb-dip of 88 Sr using a spectral frequency width of 35 MHz.
