Book Description
A fluid-bed process for the preparation of dense, spheroidal uranium dioxide particles directly from uranium hexafluoride for dispersion and compacted fuel element applications has been developed. In the process, a uranium hexafluoride is reacted with mixtures of steam and hydrogen in a bed of uranium dioxide fluidized by the reactant gases and maintained at 650 to 700 degrees C. The solid reaction products deposit as a dense layer on the surface of the bed particles. The operating procedure involves alternating periods of uranium hexafluoride feed periods of fluoride cleanup when only steam and hydrogen are fed. Product is withdrawn at the end of each cleanup period.

Book Description
Fluid-bed, fluoride volatility processes are being developed for the recovery of uranium and plutonium from spent nuclear fuels for power reactors. In these processes, chemical separations are achieved by formation of the volatile hexafluoride compounds of uranium and plutonium.

Book Description
A fluid-bed fluoride volatility process for the recovery of uranium from highly enriched uranium-Zircaloy-2 and uranium-aluminum alloy fuels has been develop. The conceptual process involves two basic chemical reaction steps conducted in a fluid-bed reactor. In the first step, the alloying material is separated as a volatile chloride by reaction with hydrogen chloride. In the second step, the uranium is recovered as its volatile hexafluoride by reaction with fluorine.
