Abstract: "The effect of heat treatment of 2000 to 4650 F on the structure of carbons from several sources have been investigated, using X-ray diffraction. Of particular interest was the effect of temperature on the degree of graphitization. The process of graphitization results in a larger graphite crystallite size in the ao direction, the plane of the layers, than in the co direction. No correlation was found between the structure of the coke heated at 2000 F and the degree of graphitization attained at 4650 F. Materials coked in a closed retort yielded a more perfect graphite structure than the same material coked with access to air. Carbon blacks yield graphite with a greater co lattice constant than cokes with comparable crystallite sizes."

The following memorandum discusses experiments and methods to recover uranium from Colorado-Utah sandstone and leaving the vanadium in the tails, improving filterability.

"This note presents the results of a parametric study of heat-generating graphite plates with hydrogen coolant flowing through constant area passages. The heat generation within the graphite was assumed to have a distribution that allowed the centerline temperature of the plates to remain constant at 5000 F. The parametric variables were the mass flow rate per unit area, plate thickness, plate length, and passage hydraulic diameter. The machine calculations were coded by Ivan Cherry, T-1."

Abstract: The results of both dry and wet attritioning of Temple Mountain ore are presented. In order to obtain effective attritioning on this ore, the amphaltite must be removed before attritioning. With the asphaltite present, dry attritioning causes a build-up of asphaltite on the surface of sand grains, with consequent loss of uranium values. In wet attritioning, the asphaltite is not broken down or attritioned, because of its low specific gravity and resilience.

Abstract: Yazzie Mesa was examined in May 1951, by the writer, assisted by R. C. Cutter. The mesa shows one main channel deposit and three minor channels. The main channel appears to be a northern extension of a channel deposit being worked by the Vanadium Corporation of America at their Monument No. 2 mine. Two samples taken on the south outcrop of the main channel assayed 0.16% U308 over 4.5 feet and 0.80% U308 over 1 foot. The area is recommended for 10,000 feet of exploration drilling. It is not intended to recommend this footage as a separate contract unit as this report covers only a small part of an area in which drilling will be recommended in forthcoming reports.

"This memo shall be an attempt to write down in a consistent manner some expressions for conversion ratio so that a comparison can be made with regard to a uniformly loaded core versus a flattered zone surrounded by an unloaded region. The discussion will be limited to the type of loading that is at present being considered for the reactor - a checkerboard array of MTR fuel elements and feed elements; the unloaded reactor will consist of fuel elements only."

Abstract: "The data reported herein furnish a qualitative comparison of the rapidity of vaporization of TCl4 at various "hot zone" temperatures as well as a measure of the chlorine evolution attributed to its thermal decomposition. The presence of impurities in the TCl4 detracts from the significance of the reported chlorine evolution. The temperature recommended for rapid volatilization is 750 C at which TCl4 underwent thermal decomposition amounting to no more than 0.2% by weight."

Technical report: Measurements have been made on the equilibrium between Cu, Cu2+, U4+, and UO22+ in H2SO4 in an attempt to establish the value of the U4+ - UO22+ couple potential. The value of the formal potential for the U3+ - U4+ couple in 1N HCl at 0 degrees C was determined to be + 0.65 v.

An investigational drilling project carried out for geological information to determine if several claims near Hite, Utah, warranted an extensive drilling project.

From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey which covered a region of North Texas, New Mexico and Oklahoma. The specific area of this report as outlined on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles and each tie line was flown in a north-south direction with an average length of 69 miles. Map lines and tie lines were surveyed spaced at intervals indicated on Figure 2. The data for the total area of Figure 1 were gathered between March-July, 1976.

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.

Abstract: "The transformation of metastable beta uranium crystals was found to proceed by a martensitic reaction at room temperature. The features of the transformation of particular interest were that individual uranium martensite plates formed isothermally and grew at a slow rate isothermally."
