The recovery of iodine released during the processing of used nuclear fuel poses a significant challenge to the transmutation of radioactive iodine. During the first two years of this program the use of Fullerene Containing Carbon (FCC) compounds and Natural Organic Matter (NOM) as potential sorbents for iodine release from the reprocessing of nuclear fuel was examined. This work also included the development of bench-scale testing capabilities at UNLV to allow the testing of the FCC and NOM materials in a simulated process off-gas environment. In the final year of the project we will complete studies of FCC and NOM and develop a method for conversion of recovered iodine into NaI. In addition, this work will also examine the development of a process to convert the iodine-loaded carbon matrices into a ceramic material with the potential for use as either a transmutation target or as a waste form in a partitioning and sequestration strategy.
