An off-gas treatment system is being developed for the collection of volatile fission products during a head-end processing step. The head-end processing step employs high temperatures to oxidize UO2 to U3O8 resulting in the separation of fuel from cladding and the removal of volatile fission products. Three volatile fission products have been targeted for trapping on distinct zones of the off-gas system and within those zones, on individual filters. A description of the filter media and a basis for its selection will be given along with the collection mechanisms and design considerations. Results from testing with the off-gas treatment system will also be presented.
