Grain Refinement of Uranium by Alloying
Binary alloys of uranium with 38 elements in the range 0.01 to 1.0 at.% were made. Three alloys having nominal compositions of 0.01, 0.1, and 1.0 at.% were made with most of the elements, and in addition, 12 ternary and quaternary alloys were made. The alloys were cast, rolled to 7/8-inch-diameter bars, heat treated, and examined for grain size.

Jacketing of Uranium for High-Temperture Service
From introduction: "The work covered in this report is a portion of the experimental research undertaken for the design of a uranium-containing metallic fuel rod for operation in air at 1090 C...This report deals with that phase which involved the testing and evaluation of various metals as barrier costs between uranium alloys, and low-carbon steel. The work is of a preliminary nature and is concerned more with a comparison of the various barrier metals than with the acquisition of numerical data, e.g., diffusion coefficients."

Mineralogical Examination of Pitchblende Concentrates and Nitric Acid Digest Residues
This report has two parts to it discussing mineralogical examination of pitchblende concentrates and nitric acid digest residues. Part I gives the results of a cursory examination with the petrographic microscope of samples of pitchblende concentrates and residues to see if there is a relationship between the mineral composition of the samples and the filterability of the residue. Part II gives a revaluation of the data in Report BMI-241 on the mineral composition of two residues from the nitric acid digestion of pitchblende concentrates at the Rallinckrodt Chemical Works.

The Decontamination of Uranium from Fission Products by the Use of the Uranyl Oxalate Precipitation Reaction
Abstract: "Decontamination factors of the order of 10-4 were obtained for Beta and Gamma emitters present as fission products when uranium was precipitated from 50 mC activity level solutions as uranyl oxalate under normal uranium yield conditions for three cycles (~60%). Factors of the order of 10-3 were obtained by the use of this reaction with similar solutions under relatively high uranium yield conditions for three cycles (~90%). The uranium peroxide precipitation reaction proved to be of no value on such solutions, yielding decontamination factors of only 17.1 Beta emitters and 1.2 for Gamma emitters for three cycles."

Preliminary Summary of Reconnaissance for Uranium in Arizona
From introduction: A reconnaissance of Arizona uranium deposits was started in October 1950 and continued through April 1951. A total of six man--months was spent by H. C. Granger, E. P. Kaiser, and J. W. Adams. About 40 properties were examined and, of these, six were mapped by plane-table method and six were sketch-mapped. This reconnaissance was not intended as a complete evaluation of all Arizona deposits; other areas and occurrences were not examined during the investigations and are not discussed in this report.

Preliminary Report on the Carnotite Deposits of the Old Leyden Coal Mine, Jefferson County, Colorado
From introduction: Mapping, sampling, and radiometric reconnaissance of the uranium-bearing deposits in the Laramie formation in the vicinity of the Old Leyden coal mine, sec. 28, T. 2 S., R. 71 W., Jefferson County, Colorado (fig. 1), was completed August 10, 1951. Topographic and geologic maps were made of areas approximately 6,000 feet by 3,000 feet (scale 1:2h00), and 1,200 feet by 800 feet (scale 1:600). Underground workings at three clay mines and at the Old Leyden mine were also mapped. With the exception of the 1:600 map, which accompanies this report, these maps will be transmitted later with a more comprehensive report.

Preliminary Summary of a Reconnaissance for Uranium in the Alaska Railroad-Iliamna Region During 1951
From abstract: Radiometric reconnaissance in several districts of the Alaska Railroad-Iliamna region during 1951 found no radioactive material in excess of 0.002 percent equivalent uranium associated with certain lode deposits that previously were deemed favorable for the occurrence of uranium because they contain mineral assemblages similar to uranium-producing lodes elsewhere.

Airborne Radioactivity Survey of the Red Desert Region, Sweetwater County, Wyoming
From abstract: An airborne radioactivity survey of a selected area in the Red Desert, Sweetwater County, Wyoming, containing outcrops of radioactive lignites and shales of known surface extent and uranium content, was flown on flight lines at three levels, respectively 250, 500, and 1,000 feet above the ground and spaced at one-quarter mile intervals. Measurements from three identical dual-channel radiation detectors were simultaneously recorded to obtain data at various distances from natural radioactive sources of known configuration. The radiation intensity measurements were fully corrected for all extraneous effects and were compiled as profiles of radiation intensity, as an isoradioactivity contour map, and as curves showing the relationship between radiation intensity and distance from the source.
