Electroplates on Thorium
Description:
Abstract: "The protection of thorium in hot water was studied. Copper electrocladding on thorium offers promising protection against hot water. The corrosion of thorium in 95 C water was reduced appreciably by a thorium phosphate film. The results of this abbreviated investigation offer a basis for the development of a method of protecting thorium at elevated temperatures in corrosive media."

The Fabrication of Thorium Tubes
Description:
Abstract: "Thorium tubes were cold drawn from extruded tube stock and also from drilled hot-rolled rod. Total reductions up to approximately 85 per cent were accomplished by conventional tube-drawing methods, without an intermediate anneal. The hard-drawn tubes had high tensile strength, but the ductility, as indicated by flaring and flattening tests, was low."

Creep Strength of Uranium Alloys at 1500 and 1800 F
Description:
Abstract:"The creep resistance of various uranium binary alloys was investigated at 1500 and 1800 F in vacuum. Tests were made on alloys of uranium with beryllium, columbium, molybdenum, tantalum, titanium, and zirconium and on molybdenum-UO2 composites. Of the alloys examined, those of the uranium-molybdenum system exhibited the best creep resistance. At 1500 F, creep rates of about 0.005%/hr were produced in uranium-molybdenum alloys by a stress of 2500 psi and, at 1800 F, similar creep rates…

The Ductility of Brazed Stainless Steel Joints
Description:
Abstract: "The ductility of Type 310 stainless steel T-joints brazed with GE-62 brazing alloy was measured at room temperatures 1200, 1650, and 1800 F. The measure of ductility was taken as the plastic axial strain required to crack braze fillets in T-section tensile specimens. At elevated temperatures, the ductility of as-brazed joints approximated that of the stainless steel, but at room temperature the brazed joints had only one-tenth the ductility of the base metal. Annealing for 16 hr at 1…

Progress Report on Nonaqueous Extractive Methods for Western Uranium Ores
Description:
Abstract: "Dissolution of carnotite in several readily liquefiable gases, including ammonia, sulfur dioxide, chlorine, and nitrogen dioxide, was found to be negligible, even in the presence of uranium complexing agents. No low-boiling liquids have been found which will dissolve carnotite directly. Treatment with various sulfur chloride will convert carnotite to a form soluble in water or in certain organic solvents. Also, carnotite can be readily dissolved in HCl-acidified ethanol, methanol, or…

Determination of Rare Earths in Refined Uranium : Topical Report
Description:
Abstract: "Rare-earth analyses were performed on several samples of refined uranium oxide and nitrate, using a modified cellulose column procedure. Rare earths were not detectable in samples of 0.03 shotgun of less. Detection limits were from 0.0005 to 0.015 ppm. Negligible quantities of low-cross-section rare earths were found in less pure uranium samples, obtained during start-up operations of the pilot plant at the Feed Materials Production Center, primarily those rare earths of greater than…

Identification of Reaction Products Formed During Magnesium Reduction of Uranium Tetrafluoride: Report
Description:
Abstract: "This report describes the results of X-ray diffraction examination of reaction products from a series of experiments performed by Mallinckrodt Chemical Works as an acid in understanding the process of bomb reduction of UF4. UF4 is initially reduced to UF3 by magnesium at 560 C., and subsequently to metal at 600 C. MgF2 from the initial reaction forms a coating on the magnesium which retards the final spontaneous reaction."

Notes on Evaporation of Target Materials
Description:
Abstract: "The general utility of vacuum evaporated films is discussed. The characteristics that makes this technique most useful are the uniformity of the films, the easy control of their thickness over a large range, and the adaptability of the system to different metals and compounds. The design of a vacuum evaporator should provide adequate pumping speed, cooling of components, filament heater supply, and general flexibility and adaptability of the components to different materials. The des…

Preliminary Report of the Results of Reconnaissance for Uraniferous Materials in the Powder River Basin, Wyoming
Description:
From introduction: During three months of the summer of 1952, a geologic and radiometric reconnaissance examination for uraniferous materials in the peripheral parts of the Powder River structural basin in northeastern Wyoming (fig. 1) was made by the Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. The purpose was to find, describe, locate, and sample deposits of uraniferous or radioactive materials other than those in the central part of the Powder Rive…

Reconnaissance Geology of Placer Deposits Containing Radioactive Minerals in the Bear Valley District, Valley County, Idaho
Description:
From introduction: The Bear Valley district is situated in southwestern Idaho, in the drainage of the Middle Fork of the Salmon River (see fig. 1). The placer deposits were drilled by the U. S. Bureau of Mines in 1951 and 1952 to determine their content of monazite and "radioactive black minerals" (here referred to loosely as "radioactive blacks"). The purpose of the study outlined here was to provide a geologic background for an understanding of the origin and distribution of the placer minera…

The Comet and Gray Eagle Mines and Adjacent Area, Jefferson County, Montana
Description:
Abstract: Anomalous radioactivity and uranium minerals have been found on the dumps of the Comet, Gray Eagle, and Silver Hill mines situated along the Comet-Gray Eagle shear zone. The shear zone is from 50 to 200 feet in width and has been traced 5 1/2 miles. The Gray Eagle mine is currently being reopened but no underground work, with the exception of a few shallow shafts and adits, has been done between the Gray Eagle and Comet mines. Because of the high U3 08 content of the samples from the …

A Radiometric Traverse Along the Alaska Railroad
Description:
Abstract: A sample of carnotite, thought to have been found in the Alaska Railroad belt, was assayed at the Fairbanks Assay Office in 1918, but the exact location from which the material had come was never determined. A "uranium" prospect, apparently unrelated to the carnotite occurrence, was recently staked 4 miles south of Healy. A radiometric traverse along the railroad was undertaken in 1950 in an effort to locate any possible deposits of radioactive material in the vicinity of the right-of…
