Abstract

Removal characteristics of H14CO3- ion from IRN-150 mixed resin contaminated with 14C radionuclide and a gasification behavior of 14C radionuclide to 14CO2 were investigated. The stripping solutions used for the removal of 14C from spent resin were NaNO3, Na3PO4, NH4H2PO4, H3PO4. The influence of stripping solution concentration on the desorption characteristics of inactive HCO3 ion into stripping solution from IRN-150 mixed resin and the gasification of this ion to CO2 was analyzed. The gasification behavior to CO2 by using NaOH, HNO3, HCl was also compared to that of phosphate solution. Real spent resin stored in Wolsung nuclear power plant was used to evaluate the gasification characteristics of 14C radionuclide to 14CO2. Gamma radionuclides such as 137Cs, 60Co in residual striping solutions after desorption experiment were analyzed.
