Non–destructive radiotracer technique in characterisation of nuclear grade anion exchange resins Tulsion A–30 and Dowex 550A LC
The present study deals with the application of non–destructive radio isotopic tracer technique to evaluate the performance of nuclear grade resins Tulsion A–30 and Dowex 550A LC. The evaluation was made by testing the performance of the two resins during iodide and bromide ion–isotopic exchange reactions. It was observed that at a constant temperature of 30°C, as the concentration of labelled iodide ion solution increases from 0.001 mol/L to 0.004 mol/L, the percentage of iodide ions exchanged increases from 66.90% to 74.10% for Dowex 550A LC resins and from 60.70% to 67.80% for Tulsion A–30 resins. Similar trend was observed for the two resins during bromide ion–isotopic exchange reaction. The overall results indicate superior performance of Dowex 550A LC resins over Tulsion A–30 resins under identical operational conditions of temperature and ionic concentration of external solution.
