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.

The First Crystallographic Data for Curium Compounds
Abstract: "X-ray powder patterns of two curium compounds, the trifluoride and the oxide, have been obtained, using sub-microgram specimens. The fluoride prepared by precipitation from aqueous solution with HF is isomorphous with NdF3. Treatment of CmF3 with F2 (g, 1 atm.) did not convert it to CnF4 or higher fluoride. Air ignition of curium oxalate gave a compound having a cubic lattice with a constant expected for Cm2O3 rather than for Cmo2. Due to the extremely high level of gamma and x-radiation accompanying Ca-242 alpha emission (162 days half-life)-(2,3), it has heretofore been impossible to obtain x-ray powder patterns of any curium compounds. Another difficulty has been the danger of contamination, as the specific activity of curium is 7 x 10-9 d/m/[mu]g. We have found that patterns, even though of poor quality, sufficient to identify the structure can be obtained by using very small samples in thin, tapered capillaries with short exposure times."

Specific Surface and Bulk Density of U3O8 and UO2 as Factors in UF4 Production on the 250 Gram Uranium Scale
Specific surface and bulk density measurements were made on samples of 22 U308 materials which had been prepared by calcination at 900°C of widely differing uranium peroxide precipitates and had been evaluated as to "reactivity" by successive treatment with hydrogen and a mixture of anhydrous hydrogen fluoride and hydrogen in a production-type batch process for the preparation of UF4. Specific surface and bulk density measurements were also made on samples of the 22 corresponding U02 intermediates. The ranges of values encountered in the U308 samples and in the U02 samples were 0.05 m /g to 0.37 m /g and 0.03 m /g to 0.33 m /g, respectively, for specific surface and 3.7 g/cm to 1.8 g/cm and 4.9 g/cm to 2.7 g/cm3, respectively, for packed bulk density. Specific surface varied inversely with packed bulk density for U308, the data showing a good correlation. A very poor correlation between specific surface and packed bulk density of U02 was obtained. The conversion of U308 to UF4 n the standard process varied from 22% for the lowest specific surface, highest bulk density oxide to 98 to 99% for the high specific surface, low bulk density oxides. The observed values for properties of the …

Interpretation and Evaluation of the Uranium Occurences Near Goodsprings, Nevada: Final Report
Abstract: The uranium occurrences near Goodsprings, Clark Co., Nevada, are divided into two distinct types which differ from each other in geographic distribution, localization of mineralization, mineralogy and origin. None of the known deposits is of present commercial significance and therefore this study emphasizes the genetic rather than the economic aspects.

Use of Controlled Photosynthesis for Maintenance of Gaseous Environment
Abstract: "The problem of maintaining livable oxygen and carbon dioxide pressures in a closed space in which men must live leads to consideration of the possible use of the photosynthesis of green algae. A calculation based on the known respiratory rate of man and the photosynthetic rates of Chlorella indicates that it would be feasible to use algae for this purpose."

High Energy Fission and Spallation of Uranium
From introduction: "This report is an attempt to examine, semiquantitavely, the way the competition between neutron emission and fission varies for heavy nuclei as a function of nuclear type and excitation energy. Many of the ideas herein are the results of discussions with R. H. Goeckermann and W. Heckrotte of the University of California Radiation Laboratory."

Preliminary Report on the Rimini Area, Jefferson City Quadrangle, Jefferson County and Lewis and Clark County, Montana
Abstract: A number of radioactivity anomalies and secondary uranium minerals have been found in the Rimini area near the northwestern margin of the Boulder batholith. Most of the anomalies are associated with chalcedonic vein zones that consist of one or more veins of cryptocrystalline and fine-grained quartz in silicified quartz monzonite and alaskite. Seventeen of the anomalies were found along veins that contain base and precious metals; nine were along veins in the vicinity of the village of Rimini from which there has been production of lead, silver, zinc, and gold.

A Pebble-Bed Reactor for Stationary Power Plants
A preliminary study has been made of a solid homogeneous reactor for stationary power plant application. The core consists of graphite spheres impregnated with uranium and thorium, and the coolant is bismuth. This concept possible offers advantages over other solid fuel reactor systems with respect to simplification of core structure, fuel fabrication and fuel handling, and reduction of fuel inventory external to the reactor. From the results of this preliminary study, it appears that the potential cost of electric power from this reactor is competitive with that from other reactor systems which have been proposed for the same application. The Po210 produced in the coolant presents a decontamination problem, but is also possibly a valuable by-producgt.

The Determination of Product Variability
One of the distinguishing features of many chemical production processes is that the process variation is obscured by measurement errors which are of the same order of magnitude or greater. This paper will discuss some elementary means of estimating true product variability under these conditions.

Electrodecontamination of Stainless Steel
Abstract: "In experimental studies, decontamination factors of 1000 to 3000 were obtained by electrostripping deposited radioactivity from stainless steel surfaces, used as the anode, in 2% sulfuric acid at current densities as low as 0.01 amp/in.-2. Stainless steel cathodes were used. The method was successfully applied to contaminated equipment."

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."

Effect of Plutonium on the Fluorometric Determination of Uranium
The fluorometric method for determining microgram quantities of uranium dissolved in concentrated sulfuric acid was reinvestigated for the purpose of measuring any interference caused by plutonium in uranium samples. No plutonium fluorescence, and therefore no positive errors due to plutonium, were observed. Limited transmittance of hexavalent plutonium in sulfuric acid at 513, and especially at 360 millimicrons, produces variable negative errors in uranium determinations.
