The Catalytic Extraction Process (CEP) is a flexible and innovative technology which can process hazardous waste streams in a wide range of chemical and physical forms. The capabilities of CEP technology have been demonstrated on a commercial-scale prototype on RCRA listed hazardous waste streams. The results indicate that CEP can achieve almost 100% recycling of feed to commercially valuable products while maintaining high environmental performance. Specifically, CEP achieves Destruction Removal Efficiencies (DREs) {ge} 99.9999% with no detectable amounts of trace components. Furthermore, any solid products are non-leachable. Quantum-CEP{sup TM}, a technology that has evolved from CEP, allows processing of mixed waste streams and preparation for final form disposal. This paper discusses the theoretically achievable and experimentally demonstrated radionuclide partitioning achieved by Quantum-CEP. It also discusses the theoretical foundations and experimental evidence of Quantum-CEP`s flexibility to drive partitioning to the desired phase by manipulating operating conditions, hence significantly improving volume reduction. Specifically, this paper focuses on (i) processing contaminated scrap metal and (ii) processing contaminated ion exchange resins using Quantum-CEP. Radionuclide surrogate demonstrations using CEP outlined in this paper indicate decontamination of metal to greater that 99% (limited by the lower detection limit (LDL)) while achieving stabilization of the vitreous phase. Processing of ion exchange resins contaminated with radioactive cobalt and cesium using CEP indicate complete recovery and concentration of the cobalt in the metal phase and condensation and capture of the cesium from the gaseous phase.
