Title: Multi-Cycle Cesium Ion Exchange Testing Using Spherical Resorcinol-Formaldehyde Resin with Diluted Hanford Tank Waste 241-AP-105

Abstract

Washington River Protection Solutions requested that at least 4 L of Hanford tank waste collected from tank 241-AP-105 and diluted to approximately 5.6 M Na (AP-105DF) be prepared for use in vitrification studies. Cesium removal was required to meet this objective and the waste pretreatment platform, established at Pacific Northwest National Laboratory, was used to create the vitrification feed. The Test Platform mimicked the Low-Activity Waste Pretreatment System (LAWPS) facility planned to pretreat Hanford tank waste supernate by removing solids in a cross flow filter apparatus and processing the supernate through ion exchange columns to remove cesium. At the time of testing, the ion exchange media was targeted to be spherical resorcinol-formaldehyde (SRF) resin. The SRF resin has been tested with a wide array of simulants and process scales, but column performance testing with actual tank waste had been somewhat limited to two Hanford tank wastes (AP-101 and AN-102) in up to two process cycles. This report describes testing conducted in a total of six load elute cycles with the AP-105DF tank waste. The column system was first tested with simulant and was previously described , ; this report describes the six process cycle results with the AP-105DF tank waste.
