Dry Fluoride Process Status Report (open access)

Dry Fluoride Process Status Report

Technical report outlining how uranium hexaflouride was prepared be the direct combination of irradiated uranium metal with elemental fluorine and subsequently decontaminated by adsorption, filtration, and sublimation on a laboratory scale. Report proposes a survey of other methods of preparing UF6 from uranium metal, a study of adsorption techniques for removing plutonium from UF6, and an investigation of fractional distillation for removing the volatile fission product fluorides from UF6.

Linear Accelerator for Heavy Ions (open access)

Linear Accelerator for Heavy Ions

The following report discusses the construction of two heavy-ion linear accelerators, one at the the University of California Radiation Laboratory and the other at Yale University. The goal for these accelerators is to produce ions of masses up to that of neon with energies of 10 Mev per nucleon.

The Ratio of Alpha to Beta Activity of Natural Atmospheric Radioactivity (open access)

The Ratio of Alpha to Beta Activity of Natural Atmospheric Radioactivity

Abstract: The alpha to beta ratio of naturally occurring radioactivity in the air has been investigated. The study has concerned itself primarily with radon daughter products collected on filter-paper samples from the time equilibrium has been established on the paper through elapsed times during which radioactive counting is normally accomplished. Calculations showing the change in this ratio of activities during the above period are presented. From this work it appears that the observed constancy of ratio does have theoretical justification and that departures in alpha-to-beta ratio would be a usable approach to the detection of long-lived alpha or beta radioisotopes in the atmosphere.

Canning depleted uranium : production test 313-110-M, final report (open access)

Canning depleted uranium : production test 313-110-M, final report

From summary: "Uranium billets deficient in U235 were subjected to the normal successive steps in the slug fabrication process; viz., rolling, machining, and canning. No unusual behavior was observed at any point in the process, thus indicating that the depleted metal from the standpoint of mechanical properties can be considered equivalent to normal uranium."

Studies on the Electrolytic Reduction of Nitric Acid (open access)

Studies on the Electrolytic Reduction of Nitric Acid

Report discussing the reduction of nitric acid that results from its use at the cathode for the electrolysis of uranyl nitrate. From introduction: "It is the purpose of this report to give the results of studies on the reduction of nitric acid of different concentrations, at different types of electrodes, and for various current densities in order to ascertain the effects of such changes."

The Effect of Fluoride on the Corrosion of Stainless Steel in the Presence of Excess Al+3 Ion (open access)

The Effect of Fluoride on the Corrosion of Stainless Steel in the Presence of Excess Al+3 Ion

Technical report detailing corrosion tests of Type 347 stainless steel for two weeks in boiling uranyl nitrate, sulfuric acid media, with and without additions of Al+3 and F-1 in a 2:1 mole ratio. The results of these tests show that although the presence of aluminum greatly reduces the deleterious effect of fluoride, the corrosion rates are still three to four times greater than when no fluoride is present.

Thorium-Molybdenum Phase Diagram (open access)

Thorium-Molybdenum Phase Diagram

From abstract: "The phase diagram of the thorium-molybdenum alloy system has been determined to be the eutectic type with a eutectoid reaction associated with the thorium alpha-beta transformation. X-ray, thermal, electrical resistance and metallographic methods have established the eutectic point at 1380 ± 10°C and 7.0 ± 0.5 wt % molybdenum. A eutectoid reaction is proposed at 1358 ± 5°C and less than 0.1 wt % molybdenum. No solubility of thorium in molybdenum was detected at 1325°C."
