High-porosity ceramic nanofiber membranes are developed and studied for separation and sequestration of gasified fission and poison radioelements related to the Modified Open Fuel Cycle. Fabrication strategies and parameters for development of high surface area membranes are explored, with demonstration of surface functionalization for sensitizing and remediation of simulant streams for radionucleotides of interest. Stability testing of the loaded fiber membranes in encapsulation glass waste forms also will be presented. The one step gettering and sequestration of volatile fission and poison nuclear waste provides a simplified and universal waste form, while allowing for majority of the fuel to be recycled back into the fuel cycle. Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy's National Nuclear Security Administration under contract DE-AC04-94AL85000.
