Abstract: "The deuterium plasma which is ejected by a 6000-ampere pulsed current through a rail-type spark source has a yield in the forward direction which is a factor of 5 to 10 greater than that in the perpendicular direction. This effect is believed to be due to the magnetic propulsion of the plasma."

Abstract: "Since the first report on the use of amines as uranium extractants (ORNL-1734) over eighty additional organo-nitrogen compounds have been examined for their ability to extract uranium from aqueous solutions, particularly sulfate solutions, of the types usually encountered in uranium ore processing. As before, the more promising of these (as well as other compounds previously reported) have been examined further with respect to other characteristics essential to practical application, i.e., reagent loss to the aqueous phase, compatibility with practicable diluents, influence of commonly present anions, reagent stability, sufficient selectivity for uranium, adequate phase separation properties, compatibility with practicable stripping methods, etc. The potential cost and availability of the reagents tested, i.e., certain secondary and tertiary amines, have shown even greater promise as practicable extraction agents than many of the promising compounds previously tested. In addition to the work with sulfate liquors, cursory studies have been made of uranium extraction from fluoride and sulfate-fluoride solutions. Extractions of other metals from sulfate liquors, i.e., titanium and thorium, have been briefly examined."

Two methods are described for extending the Thomas-Fermi model of a compressed atom to molecules or mixtures of the type Z Zn. The methods are applied to H2O at zero temperature to determine pressure and internal energy as functions of the density, the position of the protons relative to the oxygen nucleus, and the electrostatic potential distribution within the molecule.

An ion-exchange -- polarographic method was developed for the determination of iron(III) in Homogeneous Reactor Fuels. Copper, which interferes, is removed from the fuel by plating it onto a cadmium coil. Iron is oxidized to iron(III) by potassium permanganate, and the iron(III) is separated from interfering metal ions by ion exchange on a Dowex 1 resin column that is in the sulfate form. The iron(III) in the effluent is determined polarographically in 0.5 M sodium citrate solution as supporting electrolyte. A fairly well defined polarographic wave is obtained for the iron(III) → iron(II) reduction at a half-wave potential of approximately -0.15 v. vs. the S.C.E. The relative standard deviation of the data for 2 µg of iron(III) per ml of solution in the polarographic cell was 6.5%; for 10 µg of iron(III) per ml it was 0.6%.

The ORNL 86-in. cyclotron is being modified to provide for deflection of the proton beam. It is expected that operation will be resumed late in the spring. Nuclear physics work was limited, for the most part, to interpretation of previously collected data and to making preparations for utilizing the deflected beam. It was found that for certain isotopes the production rates could be almost doubled by operating at a slightly reduced energy and a much larger current. With the use of the ORNL 63-in. cyclotron, the absolute values of the electron capture and loss cross sections for 26-Mev nitrogen ions were obtained. The angular distribution of the cross sections for elastic scattering of nitrogen by nitrogen was measured at energies from 13 to 22 Mev. A double-focusing 90-deg magnet is being planned for use in identifying stable reaction products from nitrogen-induced reactions. The major components of the revised 44-in. test cyclotron were assembled and are being tested. Consideration is being given to the use of these components, along with a new 20,000-oersted magnet and a shielded cyclotron room, and if the tests are satisfactory the Laboratory will have available a machine which will accelerate N5+ ions to 81 Mev.

A process for hot-press canning of unplated thorium cores in aluminum jackets was developed using wafers of thorium and aluminum for diffusion and bonding studies.

In this document, simple modes are used to demonstrate the importance of different material effects on predicted material behavior. This document should help one understand the basic assumptions made in stress analysis.

The effects of variables on the rate of Purex solvent deterioration were investigated with the emphasis on those deterioration products which cannot be removed by carbonate washing. The deterioration rate was found to be directly proportional to the acid and nitrate ion concentrations, and proportional to the square root of the concentration of nitrite ion. Other observations on the effects of temperature, relative merits of brand name solvents, and the effects of radiation are included. A method of calculating the equilibrium level of the solvent deterioration products based on study conclusions and various estimates is outlined.

Part A. The major effort during the past year has been the construction of a suitable vacuum furnace for studying the effects of temperature and pressure on the wettability of metals by glass. A systems was completed that was capable of subjecting test combinations up to temperatures of 1400 degree C at a working pressure of 1 x 10(-5) mm. of Hg. Part B. A compound, identified by X-ray analysis as sodium meta tantalate (na2Ta2O6), was found at the interface between a sodium silicate glass and tantalum metal which had been heated in vacuum to 1000 degree C. thermodynamic calculations, followed by further experimental evidence, were used to determine the chemical reaction between tantalum and sodium silicate which resulted in the formation of Na2Ta3O6. the compound was synthesized by other methods, and its structure investigated.

A generalization of the Lindemann law is used in connection with the Murnaghan equation of state for a solid to derive theoretically the empirical Simon equation for the fusion curve. For the alkali metals it is shown that experimental values of the temperature exponent in the Simon equation are quantitatively compatible with the theoretical evaluation given, and, furthermore, that the theory can predict approximate values of the experiment, in practice.

As an aid in forecasting possible blast damage in areas distant from a bomb burst point, a special-purpose electronic analog computer has been developed. Sound ray paths (orthogonal trajectories to sound wave front) are computed as a function of meteorological conditions.
