Ultracentrifugal Measurements on Uranyl Fluoride Solutions

Description: Abstract: "Activity coefficient ratios for UO2F2 were measured at 30 C by ultracentrifugation to equilibrium. The method was checked with CdI2. The results for UO2F2 confirm the hypothesis of a monomer-diner equilibrium which was used previously to interpret the freezing point depressions of UO2F2 solutions. The dimerization constant at 30 C was found to be somewhat greater then at the freezing point. The proportionality constants for the dependence of the logarithm of the activity coefficients on molality were found to be essentially temperature independent. The heat and entropy of dimerization were estimated. Experiments in the presence of an indifferent electrolyte (NaClO4) support the assumption that dissociation into ions is slight. In potassium fluoride solutions, uranyl fluoride dimerizes more extensively than in water solutions."

Density and Refractive Index of Uranyl Fluoride Solutions

Description: "In the course of an ultracentrifugal investigation of uranyl fluoride solutions, their densities and refractive indices were measured as a function of concentration. The measurements were carried out near 25 and 30 C and if necessary extrapolated to 25.0 and 30.0 C from the observed temperature coefficients. Most density data were obtained pycnometrically (25 cc samples) and a few gradient tubes. The refractive index measurements were carried out with a Bausch and Lomb dipping refractometer (calibrated with "known" solutions) using sodium-D light. The materials used and the analytical procedures were described earlier. Although the accuracy of the density measurements was approximately one part in 10,000, the accuracy of the determinations at high UO2F2 concentration is considerably less, in view of the uncertainty in the uranium analyses."

The Determination of Adsorbed Moisture on Uranium and Uranium Oxide: A New Method for Moisture Determinations

Description: Abstract: "A method is described for determining moisture on uranium and uranium oxides. This method should also be applicable to solid samples which, when heated, do not decompose to form water or liberate a substance which will react with Fischer's reagent. The method should be especially applicable to samples which are insoluble in alcohol or Karl Fischer reagent under normal titration conditions, or which will themselves react with the reagent. The amount of moisture on uranium and uranium oxide was found to be 0.02% except when the oxide was found to be 0.02% except when the oxide source was uranyl sulfate. In this case, the moisture content was found to be 0.1%. Modifications of the procedure and apparatus are presented for improving the accuracy and shortening the time necessary for the determination."

Investigation of Uranium Polymorphs

Description: The UO3-water system is complex and has not been fully characterized, even though these species are common throughout the nuclear fuel cycle. As an example, most production schemes for UO3 result in a mixture of up to six or more different polymorphic phases, and small differences in these conditions will affect phase genesis that ultimately result in measureable changes to the end product. As a result, this feature of the UO3-water system may be useful as a means for determining process history. This research effort attempts to better characterize the UO3-water system with a variety of optical techniques for the purpose of developing some predictive capability for estimating process history in polymorphic phases of unknown origin. Three commercially relevant preparation methods for the production of UO3 were explored. Previously unreported low temperature routes to β- and γ-UO3 were discovered. Raman and fluorescence spectroscopic libraries were established for pure and mixed polymorphic forms of UO3 in addition to the common hydrolysis products of UO3. An advantage of the sensitivity of optical fluorescence microscopy over XRD has been demonstrated. Preliminary aging studies of the α and γ forms of UO3 have been conducted. In addition, development of a 3-D phase field model used to predict phase genesis of the system was initiated. Thermodynamic and structural constants that will feed the model have been gathered from the literature for most of the UO3 polymorphic phases.

Recovery of Uranium From Wet Process Phosphoric Acid: Final Report

Description: From abstract: "The state of reduction of wet process phosphoric acid determines largely the extractability of its uranium content. This report defines the economic relationships involved over a wide range of reduction of the acid. Reductant consumption, penalties and capital investment as well as solvent consumption are evaluated."

Density and Viscosity of Solutions in the Tributyl Phosphate Process for Uranium Recovery

Description: The following report discusses the presentation of preliminary density and viscosity data which may explain whether higher viscosities of the Deo Base-TBP systems, and a change in density differences between the two phases will lead to unsatisfactory column operation.

Identification of Slag Constituents from Uranium Metal Production Bombs

Description: Abstract: "X-ray and microscopic examination of slags from uranium metal production bombs which gave good and bad yields in the plant at St. Louis have indicated the significance of uranium oxide formation. Apparently the oxide (UO2) results from reaction of the UF4 with linear material, particularly with moisture in the liner."
