Cesium Ion Exchange Using Spherical Resorcinol-Formaldehyde Resin in Support of Waste Qualification Testing for LAWPS
The Low-Activity Waste Pretreatment System (LAWPS) facility is planned to pretreat Hanford tank waste supernate by filtering solids and processing through ion exchange columns to remove cesium. The ion exchange media is currently targeted to be spherical resorcinol-formaldehyde resin (SRF). This media has been tested in a wide array of simulants and process scales, but testing to date on actual tank waste has been limited to two tank wastes. Washington River Protection Solutions (WRPS) requested a study to determine if a simple batch contact test with SRF can be used to qualify tank waste supernate prior to processing it in the LAWPS. The goal of the batch contact testing would be to determine if there are any issues with the tank waste that would preclude Cs removal by the ion exchanger.
