【 摘 要 】

The Defense Waste Processing Facilities (DWPF) at the Savannah River Site (SRS) is used to process high-level radioactive waste from the Tank Farm into borosilicate glass to reduce the mobility of the radionuclides and has processed and vitrified nuclear wastes into canisters for long-term disposal since FY96. All wastes vitrified to date in DWPF are 'sludge only' wastes. The old salt waste processing technology, ITP, was suspended in FY98 due to benzene build-up inside the tank. The new selected technologies for treating the salt waste are Actinide Removal Process (ARP) and Caustic Side Solvent Extraction process (CSSX). The Modular CSSX Unit (MCU) is a cesium removal process that will be operated downstream of the ARP. The MCU is a short-term method for cesium removal, which uses the same technology as the Salt Waste Processing Facility (SWPF). Once the SWPF becomes operational, the MCU will be shut down. The modeling request is from the MCU project to verify the validity of its Concept Design Package.
