High-dose ion exchange resins (spent resins), used for water quality control in light water reactor cooling systems, require inorganic treatment and solidification for final disposal. In this study, a simulated residue produced via wet oxidation for inorganic processing was prepared, and the chemical durability of vitrified samples containing this simulated residue was evaluated based on standardized leaching rates.
