This book was released on 1959 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-step, continuous, fluid-bed process for the conversion of uranium hexafluoride to uranium dioxide was successfully carried out in preliminary experiments in a 1 1/2-inch-diameter Monel reactor. Hydrogen and steam were used for simultaneous reduction and pyrohydrolysis reactions carried out at 600 deg C, resulting in the formation of a dense coating of dioxide on the starting bed of uranium dioxide. The effects of uranium hexafluoride feed rate and reactant excesses on conversion were investigated. Results of fluid-bed steam pyrohydrolysis runs on uranium tetrafluoride are also presented.

Download or read book Engineering Development of Fluid-bed Fluoride Volatility Processes written by Irving E. Knudsen and published by . This book was released on 1964 with total page 34 pages. 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 Product is withdrawn at the end of each cleanup period.

Book Synopsis Fluid-Bed Conversion of Uranium Tetrafluoride to Uranium Hexafluoride by : G. J. Vogel
Download or read book Fluid-Bed Conversion of Uranium Tetrafluoride to Uranium Hexafluoride written by G. J. Vogel and published by . This book was released on 1959 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments conducted in a 2 1/2-inch diameter reactor have demonstrated that the continuous fluorination of uranium tetrafluoride to hexafluoride with elemental fluorine in a fluidized bed is possible. Practicable fluorine efficiencies and conversion rates were attained with good temperature control in experiments with refined uranium tetrafluoride. Runs made with crude uranium tetrafluoride, derived from the reduction and hydro-fluorination of ore concentrates produced by the acid-leach process, indicated that these also can be processed at satisfactory rates and efficiencies. Uranium tetrafluoride derived from carbonate-leached ore concentrate gave a lower production rate and was more difficult to process because of sintering tendencies.

Available in PDF, EPUB and Kindle. Book excerpt: A new, dry process for the production of UO2 powder from UF6 by fluidization and particle-coating techniques was developed. The process involves direct conversion of UF6 to a solid, UO2F2, by hydrolysis with steam and the reduction of the UO2F2 to the dioxide by reaction with was carried out in 3-in.-dia. Monel reactors. In continuing studies, dense, spheroidal UO2 particles in the range --20 +200 mesh are being prepared. A simultaneous (steam and H2) reaction procedure at temperatures up to 7OO deg C is being used. Particle densities ranged to 9.75g/ cc or about 89% of theoretical. Sintering in H2 at about 1700 deg C for 2.5 hr gave final densities of 10.4 to 16.6 g/cc or up to about 96.5% of theoretical density. (auth).
