Determination of Hydrogen in Lithium Hydride
Abstract: "A method for determining hydrogen in lithium hydride by heating samples with lead at 600 C, was developed. The hydrogen evolved during thermal decomposition of the hydride is purified and oxidized to water with cupric oxide at 400 C. The analysis is completed by collecting and weighing this water. Success in development of the analytical procedure has depended upon a careful design and assembly of equipment for handling samples in a dry, inert atmosphere. For seven pure hydride samples analyzed by the recommended method the estimates of the standard deviation varied between 0.12 and 0.41 percent lithium hydride (or 1.3 and 4.2 parts per thousand) for 8 to 18 determinations on each sample. The procedure is relatively insensitive to variations in certain conditions. For single-piece samples weighing 0.2 to 0.5 gram it was found to be more satisfactory than a method which uses mercury in place of lead for sample decomposition. For powdered lithium hydride samples the lead and mercury methods are equally satisfactory."

Progress Report on Nonaqueous Extractive Methods for Western Uranium Ores
The following progress reports continues the investigation of the HCl-acetone process for extracting uranium, discovering that it is applicable to most Western ores, yielding high uranium recoveries. The economics of the process have been improved by substitution of sulfuric acid for part of the hydrochloric acid requirements.

Preliminary Report on the Geology and Uranium Deposits of South Elk Ridge, San Juan County, Utah
From abstract: Elk Ridge is in southeastern Utah in the central part of San Juan County. It forms a conspicuous ridge on the north end of the Monument upwarp. During the summer of 1953 field work was largely restricted to South Elk Ridge, that part of Elk Ridge which is south of The Notch. Permian and Triassic sedimentary rocks crop out in the area and Jurassic and Cretaceous rocks are exposed east of the area.

Preliminary Report on the Geology and Uranium Deposits at Temple Mountain and Green Vein Mesa, San Rafael Swell, Emery County, Utah
From abstract: In 1953 the U. S. Geological Survey started the present program of uranium investigations on behalf of the U. S. Atomic Energy Commission in the San Rafael Swell, Emery County, Utah. Two areas within the Swell were selected and studied; one in the vicinity of Temple Mountain and the other at Green Vein Mesa.

Electrical Resistivity Investigations on Holiday Mesa, San Juan County, Utah
From abstract: The purpose of this preliminary electrical resistivity investigation of Holiday Mesa, Monument Valley region, San Juan County, Utah, was to determine the feasibility of a detailed survey to delineate channels cut into the Moenkopi formation and filled with sediments of Shinarump conglomerate. These structures are in many places related to the localization of uranium ore.

The Garm-Lamoreaux Mine, Lemhi County, Idaho
From abstract: The Garm-Lamoreaux property, Lemhi County, Idaho is known to have uraninite and zippeite on two of its dumps. The property has been explored by five adits, two of which are now caved, and one of which is partly caved. The country rock is schistose micaceous quartzite and argillaceous quartzite of Belt age. An east-west fault cuts the quartzite, and the Lamoreaux vein, a gold-sulfide-quartz veins occurs in the fault. The uranium minerals are believed to have core from the vein, on the now inaccessible No. 3 level.

Progress on Geologic Studies in the Capitol Reef Area, Wayne and Garfield Counties, Utah
From introduction: Objectives of the geologic studies and mapping in this area are: 1) to study and map geologic formations in which uranium ore may be found with special attention given to the Triassic Shinarump conglomerate, 2) to evaluate uranium deposits and to study local controls and habits of ore, 3) to collect and study geologic data basic to an understanding of regional geologic trends or controls in the distribution of the ore deposits, and 4) to determine the favorableness of the area for concealed deposits of uranium. The present report does not attempt to provide answers to all these objectives. Rather, it is a brief explanatory report to accompany the geologic map (fig. 2) and make it available in advance of the final report.

The Fabrication of Subassemblies for the Supercritical-Water Reactor
In studies of the fabrication of fuel subassemblies for the supercritical-water reactor, the limited ductility of stainless steel-UOâ‚‚ fuel sheet made the fabrication of corrugated-flat-plate-type subassemblies impractical. A fabricable MTR-type assembly, 5/8 in. square and 30 in. long, was developed. Methods for edge cladding fuel sheet were developed and a brazing alloy, GE-75, was found to be corrosion resistant in supercritical water.

Corrosion of Type 347 Stainless Steel in the Uranium-Derby Pickle Bath
Abstract: In one of the final stages of the process at the Mallinckrodt Uranium Refining Center, a 45 per cent nitric acid solution at about 170 F is used to pickle the calcined magnesium fluoride scale off the uranium derbies. The increase in the fluoride-ion content of the bath tends to promote corrosion of the Type 347 stainless tanks. This attack becomes excessive if 0.3 g/liter of fluoride ion or more is present. It was found that if aluminum ion is added to the solution the corrosiveness of the bath can be controlled. Two or three times as much aluminum ion as fluoride ion present is found satisfactory at 170 F. Indications are that the tying up of the fluoride-ion by the complexion [AlF6]8 is responsible for the corrosion control.

Evaluation of Methods of Brazing Aluminum Spacing Fins to Flat-Plate Aluminum-Clad Fuel Elements
Abstract: "Four brazing methods and one other joining process were evaluated for the joining of aluminum spacer fins to flat-plate aluminum-clad fuel elements. None of these methods appear completely suitable for use in a mass-production operation. Furnace brazing and salt-bath brazing were most promising. However, the mechanical problems involved in the application of either process deter their recommendation. Resistance brazing and torch-brazing were proven impractical. The great difference in mass between the two pieces being joined prevents the use of either the resistance or torch method. Pressure bonding is not applicable because of the excessive deformation of parts being joined."

The Effects of Chemical Impurities on the Quality of Rolled Uranium Rod
Abstract: "Thirty-four uranium ingots containing controlled amounts of carbon, nitrogen, and Mgl2 slag were cast, rolled, and examined to investigate the relation between these impurities and the quality of the rolled rod. Carbon in concentrations up to 1400 ppm and nitrogen up to 170 ppm, either singly or in combination, had no significant effect on the number of defects observed in the rolled rod. The quality of the rods, however decreased with increasing amount of slag necessary to cause observable differences in the rod could not be detected on analysis, but was visible in the microstructure."
