In six experiments using fluidized-bed fluoride volatility techniques to process irradiated uranium-Zircaloy and uranium-aluminum alloy fuels, less than 1% of the uranium was retained in the reactor and filter beds. Decontamination factors for Ce, Sr, Cs, Ru, Sb, Zr, and Nb ranged from 3.5 × 105 to 1 × 108 but were 5.9 × 104, 44.6, 3.5, and 2.9 for Te, Mo, Np, and Tc, respectively. Principal volatile fission-product chlorides are Zr, Nb, Kr, and I; partially (<10%) volatile chlorides are Sb, Te, Mo, and Tc; nonvolatile chlorides are Ce, Cs, Sr, and Ru, The fluorides of Sb, Mo, Tc, Np, Nb, and Te are highly volatile but those of Ce, Cs, Sr, Zr, and Ru are nonvolatile. Iodine and krypton volatilized completely during the hydrochlorination step, and the iodine was removed completely from the process off-gas by a caustic scrubber. Tellurium was removed completely from the process off-gas with activated alumina.
