Experiments were carried out to provide information concerning the feasibility of the SCWO (supercritical water oxidation) process for treatments of LLRA (low-level radioactive) spent resins, and determined if further development of this process would be warranted. Process development in the present work was directed to minimal nuclide emission in the flue gas and a maximal possible inclusion of radioactive species in ashes which would be solidified for final disposal. Experimentally, the spent resin was completely degraded in supercritical water in a five-minute residence time. The activation energy of this SCWO reaction was 5-10 Kcal/mol. Yield of PAHs formed in the SCWO process was very low.
