Abstract: 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.
