Resin Longevity Studies
Radioactive resin waste has been generated at the Savannah River Site as a result of water treatment at F- and H-Areas. Key factors in the risk assessment of disposing of these materials in trenches include resin retention of 129I, a long-lived isotope, and the degradation rate of the organic resin itself. In order to estimate the degradation of resin wastes during underground burial, simulated aging studies were carried out with Dowex 21K, CG-8, and GT-73 ion exchange resins. These resins have a polystyrene-base but bear different functional groups. The specific resins considered in this study include anion (Dowex 21K), cation (CG8), and neutral (GT73) resins with, respectively, quaternary ammonium, sulfonate, and thiol functionalities. The objective of this study is to carry out laboratory experiments to simulate aging of organic resin wastes in order to (1) determine the functional life span of CG8, GT73 and Dowex 21K resins under field (trench) conditions, and (2) determine the expected performance of these resins as they degrade.
