Comparisons of Crystalline Silicotitanate and Resorcinol Formaldehyde Media for Cesium Removal by In-tank Column Processing
Chemical and thermal performance of crystalline silicotitanate (CST) and resorcinolformaldehyde (RF) ion exchange media were predicted for column configurations designed for installation in high level waste tanks and intended for cesium removal from radioactive waste supernates. Modeling predictions for the processing of a known Savannah River Site tank waste composition were generated. In a tw...
متن کاملWsrc-ms-2002-00149 an Optimal Ion Exchange Design for Removal of Cesium from Hanford
Non-elutable crystalline silicotitanate (CST) ionexchanger materials have been studied for removing cesium from a variety of radioactive wastes at several U.S. DOE sites over the last decade. For the current pretreatment facility design of the River Protection Project (RPP) Waste Treatment Plant (WTP) in Hanford, the removal of cesium from low activity waste (LAW) is achieved by ion-exchange te...
متن کاملDynamic Simulation of Hanford Tank Waste Remediation System
Cleaning up and disposing of approximately 50 years of nuclear waste is the main mission at the U.S. Department of Energy’s Hanford Nuclear Reservation, located in the southeastern part of the state of Washington. A major element of the total cleanup effort involves retrieving, processing, and disposing of radioactive and hazardous waste stored in 177 underground storage tanks. referred to as t...
متن کاملRegulatory off-gas analysis from the evaporation of Hanford simulated waste spiked with organic compounds.
After strontium/transuranics removal by precipitation followed by cesium/technetium removal by ion exchange, the remaining low-activity waste in the Hanford River Protection Project Waste Treatment Plant is to be concentrated by evaporation before being mixed with glass formers and vitrified. To provide a technical basis to permit the waste treatment facility, a relatively organic-rich Hanford ...

mineral dissolution and precipitation may occur. The effect of alkaline solutions on the transformation of Buried waste storage tanks at the USDOE Hanford Reservation clay minerals has been the subject of intensive research in Washington State have released solutions containing high concentrations of Na, OH, NO3, and Al into the vadose zone. When such (Cuadros and Linares, 1996; Bauer and Berge...
