Available in PDF, EPUB and Kindle. Book excerpt: As part of a continuing program on the development of fluid-bed fluoride volatility processes, methods were developed for reprocessing highly-enriched uranium-aluminum alloy and uranium dioxide-stainless steel cermet fuels. These methods involve two basic gas-solid reaction steps: a separation step, in which the cladding, the bulk constituent of the fuel, is separated from the uranium, a minor constituent of the fuel; and a fluorination step, in which the uranium is recovered through the production of the volatile hexafluoride. The reactions are conducted in a fluid bed of high-fired alumina, which serves as a heat-transfer medium. Processing of these two types of fuels differs mainly in the initial separation step: Hydrogen chloride is used to remove the aluminum as the volatile chloride; the hydrogen fluoride-oxygen mixture is employed to destroy the stainless-steel matrix by producing an oxide mixture which remains with the alumina.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 Product is withdrawn at the end of each cleanup period.

Available in PDF, EPUB and Kindle. Book excerpt: A generalized computer program, PACER-65, has been developed and utilized for flowsheet calculations and process-data reduction. PACER-65 is an executive program in which material- and energy-balance equations, conversion factors, etc., for each processing step are described by separate subroutines. The program plans the sequence of the calculations and calls the subroutines in the order required to determine all desired properties of the process streams. The effects of changes in the process flowsheet or variation of processing conditions are readily evaluated. The PACER-65 method has also been adapted for process-data reduction. In this case, the subroutine incorporate calibration data for flow-metering instruments etc., as well as equations required to perform the various calculations.
