An Investigation of Scaling of Zirconium at Elevated Temperatures

Description: "Single crystals of iodide zirconium were oxidized to determine any lattice relationship existing between zirconium and the oxide overlay, and a review of experimental data and proposed theories to explain the oxidation behavior of zirconium was made. A method of measuring the rate and depth of gas diffusion in alpha zirconium was devised, and calculations were made for the temperature range 900 to 1200 deg C using samples scaled in air, oxygen, and nitrogen. The consumption rates at lower temp… more

Rapid Reading of Large Binary Scales

Description: "A chart is presented for use in the rapid conversion of octal to decimal numbers. Tabulated data compare the decimal and octal systems, and decimal and binary numbers up to 19/sub 10/ = 10,011/sub 2/. Application of the data in reading scaling circuits is discussed."

Alternating Current Polarography: Evaluation of the Accuracy of the Data and Calculation Procedures

Description: "The data obtained by a-c polarography, when used to determine electrode parameters such as heterogeneous rate constant and when used as an analytical tool, are evaluated. Certain aspects of the experimental approach both in measurement and calculation are reviewed. The importance and means of correcting for the series resistance of the cell system itself and of using equations which take into account the phase differences between the faradaic and capacitive currents are developed. Other topics… more

Feasibility Study of Superflux Reactor

Description: "The feasibility of a three-region aqueous homogeneous reactor designed to produce a maximum thermal flux at the center of 10/sup 16/ n/cm/sup 2/ -sec is investigated. Inner and outer regions of pure D/sub 2/O and an intermediate region of uranyl sulfate in D/sub 2/O are considered. Characteristics were calculated for the case R/sub 1/ = 40 cm, R/sub 2/ = 60 cm, and R/sub 3/ = 150 cm."

Engineering Report

Description: "An evaporator system was developed and tested which will concentrate two types of non-radioactive wastes. The wastes were of the slurry type within initial concentration of 32% solids and a final concentration of 7O% solids by weight. Information concerning design practices for this type of evaporator, startup and operating procedures, methods of recovery from unexpected shutdown, and procedures for descaling was gained. The test waste was synthetic and not radioactive; however, the procedures… more

Correlation of Polarographic Walf-Wave Potentials With Nuclear Magnetic Resonance "Chemical Shifts"

Description: "Since nuclear magnetic resonance ''chemical shifts'' are considered to be good measures of electron densities in molecules, the extent to which they can be correlated with the polarographic half-wave potentials of organic compounds has been surveyed. To extend the applicability and interpretation of the proposed correlation, parallel correlation of E, with Hammett's sigma and Taft's sigma parameters were made, since both of the latter are also regarded as indication of electronic distribution … more

Polarographic Reduction of Uranium (VI)

Description: "Previous studies of the effect of uranium species on the polarographic behavior of certain organic compounds indicated the advisability of further study of uranium itself. The polarographic reduction of U(VI) to U(V) in acid solution is very sensitive to both type and concentration of anion present. Consequently, the reduction was studied using perchlorate as a non-complexing anion and sulfate as a complexing anion. In HCLO4 solution, increasing the perchlorate concentration shifted E(1/2) to … more

On the Calculation of Properties of Gases at High Temperatures

Description: "The role of the potential of intermolecular force in determining properties of gases at elevated temperatures is discussed. Coefficients of viscosity and self diffusion, isotopic reduced thermal diffusion ratios, and second virial coefficients for helium, argon, and nitrogen at 1,000, 5,000, and 15,000 d K were calculated from extrapolated potentials and from beam potentials."

The Sodium-Cooled, D2O-Moderated Rector (SDR)

Description: "For presentation at the 1958 Nuclear Congress, Nuclear Science and Engineering Conference, March 17The experimental program was focused on the problems of containing the Na, of providing a barrier material with low neutron absorption cross section and an ability to withstand the action of hot Na, of developing an arrangement of this material which is mechanically adequate, and of demonstrating that an integrated barrier system can be safety operated under reactor temperature and pressure condi… more

The Influence of the Molecular Mean Free Path on the Performance of Hydrodynamic Gas Lubricated Bearings

Description: "A modified Reynolds equation is derived for gaslubricated hydrodynamic bearings operating under ''slip flow'' conditions. Closed analytical solutions are given for a Rayleigh-type step-bearing and an inclined plane slider bearing for the case of two-dimensional flow. The influence of the molecular mean free path on the performance of bearings of arbitrary form is obtained by means of a small parameter, perturbation technique"

Summary of All-Union Conference on the Application of Radioactive and Stable Radioisotopes in the National Economy and Science of the Ussr--1957 (Aec-Tr-2925 and Aec-Tr-3093)

Description: "A total of 418 abstracts from this conference and the complete text of five plenary session papers, as well as 55 abstracts from as All-Union Conference on Radiation Chemistry, have been made available in translation in AEC-tr-2925. Almost all of these papers deal with the actual applications of tracers or radiation in the national economy. The papers presented were divided into three major sections: isotope production and high-intensity gamma systems, technical sciences and industrial uses of… more

A Kinetic Study of CO2 Desorption From Thoria

Description: "Desorption rate curves were obtained for carbon dioxide absorbed on thoria at temperatures of 550C, 450C, 350C, 250C, 150C, and 50C. The gas were found to desorb according to a logarithmic law following initial rapid desorption. The logarithmic law may be shown to be operative if the activation energy for desorption varies linearly with surface converge. A large apparent negative entropy of activation for desorption supports the fact that the adsorbed CO2 is in a mobile state."
