The University of Utah, in collaboration with Pacific Northwest National Laboratory (PNNL), proposes to develop novel membrane materials for capture of volatile iodine-129 in advanced tritium pretreatment off-gas (ATPTOG) streams generated during the aqueous-based reprocessing of used nuclear fuel. The sorbent developed through this task will be able to retain functionality in the highly corrosive off-gas and have a form suitable for implementation in a facility. The tasks associated with this project are (1) Quantification of iodine sorption capacity of metal-functionalized membranes; (2) Characterization of membrane performance under flow conditions; and (3) Synthesis and characterization of consolidated waste forms. Existing laboratory facilities will be used.
