Book excerpt: Operation of a pilot-scale system for continuous metallothermic reduction of uranium tetrafluoride (UF4 or green salt) has been initiated. This activity is in support of the development of a cost- effective process to produce uranium-iron (U-Fe) alloy feed for the Uranium-Atomic Vapor Laser Isotope Separation (U-AVLIS) program. To date, five runs have been made to reduce green salt (UF4) with magnesium. During this quarter, three runs were made to perfect the feeding system, examine feed rates, and determine the need for a crust breaker/stirrer. No material was drawn off in any of the runs; both product metal and by-product salt were allowed to accumulate in the reactor.

This book was released on 1956 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A continuous process for the reduction of uranium hexafluoride to uranium tetrafluoride was developed and proven on a pilot plant scale. Complete conversion to uranium tetrafluoride was realized by contacting a mixture of gaseous uranium hexafluoride and fluorine with hydrogen in a vibrated, vertical, open-tube reactor. The finely divided solid product contained few metallic impurities and the packed density of the material could be varied between 2.2 and 3.7 grams per cd. by regulating the amount of fluorine added.

This book was released on 1958 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A continuous process for the reduction of uranium hexafluoride to uranium tetrafluoride was developed and proved on a pilot-plant scale. Complete conversion to uranium tetrafluoride was realized by contacting gaseous uranium hexafluoride with hydrogen in a heated, vertical, open-tube reactor. The purity and density of the solid product met metal grade uranium tetrafluoride specifications. Some difficulty with the accumulation of fused uranium fluorides in the tower was encountered, however, and it was necessary to stop and desing the unit about every 8 to 24 hours. The reaction of uranium hexafluoride with gaseous trichloroethylene was stadied before the tests with hydrogen were made. Although the reduction to uranium tetrafluoride was complete, the solid product was highly contaminated with the organic by-products of the reaction and was quite low in density. Tests of this method were discontinued when promising results were obtained with hydrogen as the reductant. (auth).

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.
