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

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.

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

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 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"

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."

Tests of Models of Nuclear Reactor Elements

Description: "Losses have been determined for flow through models of various proposed core sub-assemblies as part of a study of the elements of a nuclear reactor. Six core sections and two axial blanket sub-assemblies have been compared on the basis of drop in piezometric head or pressure drop. The core sub-assemblies are composed of an entrance nozzle, a lower axial blanket section, the core section, an upper axial blanket section, and a short section for the handling lug. The four parts of the sub-assembl… more

A Monte Carlo Study of Neutron Thermalization

Description: "The slowing down of neutrons from fission to absorption energies in a homogeneous medium has been treated by a Monte Carlo method. thermalization by elastic collisions in both light and heavy water was computed on an IBM 650. One-sixth the mean-square distance travelled by the neutrons was interpreted as the migration area. This quantity was analyzed to give the age, t, both above and below the indium resonance, and the thermal diffusion constant. D, as functions of the moderator temperature, … more

Tests of Models of Nuclear Reactor Elements

Description: "These two parts were issued separately, but are cataloged as a unit. For a model of a blanket sub-assembly of the proposed Atomic Power Development Associates reactor, laboratory measurements have been made of the head losses for the blanket element and for the various distributing orifices. Tests with water have been generalized so that the results provide design criteria for liquid sodium which is to be used in the reactor."

Differential Voltammetry Using The Hanging Mercury Drop Electrode

Description: "The general techniques of voltammetry with continuously varying potential have been applied to a differential method in which two electrolysis cells are used, each with a hanging mercury drop electrode. Using this method it is possible to determine lO/sup -6/ solutions with increased precision, and it is also possible to analyze solutions as dilute as 10/sup -6/ without removing oxygen from the electrolysis cells. Mixtures can be analyzed easily by adding individual components of the mixture t… more

Precise Vapor Pressure Measurement At High Temperature

Description: "An apparatus using a silica Bourdon gage is described for the measurement of vapor pressures or dissociation pressures with an accuracy of 0.1 mm and 0.1 deg C up to maximum pressures of atmospheric or beyond and maximum temperatures of 650 to 1250 deg C. The method is applicable to corrosive substances, to substances whose vapor pressure is sensitive to slight changes in composition, and to substances difficult to purify of volatile contaminants which affect the vapor pressure."

Transient Beam Loading In Linear Electron Accelerators

Description: "The subject of beam loading in linear electron accelerators has been discussed. With suitable design it is possible to place the equilibrium electron phase angle well ahead of the crest of the traveling wave in the accelerator. With beam loading the equilibrium position will move toward the crest, but the electron energy will remain constant or nearly so over a considerable range of loading. Some loss in energy will result from moving the equilibrium phase angle off the wave crest but the spre… more
