Separation of Xenon from Krypton in UNF Reprocessing Off Gas

摘要

Reprocessing of used nuclear fuel (UNF) results in the emission of several volatile radionuclides that must be removed from the bulk off gas prior to release in order to meet U.S. regulatory emission requirements. After other volatile radionuclides have been removed, krypton (Kr) remains, along with associated stable xenon (Xe) in the gas stream.
