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."

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

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

Zircex Uranium Sublimate Loss

Description: "One of the limitations of the Zircex Process is the large percentage loss of U which is carried off with the volatile ZrCl/sub 4/. Since the ratio of U to Zr in the fuel element is quite small (< 1%), a large percentage of U loss can be caused by small amounts of U in the ZrCl/sub 4/ sublimate. The U loss must be kept below 1% if the Zircex Process is to be adapted to industrial scale processing."

Theory Of The Constant Gradient Linear Electron Accelerator

Description: "The effect of beam loading upon the design and performance of the accelerator is examined. Results are given in dimensionless form so that the various equations and grams can be used at any operating frequency. The constant gradient accelerator is somewhat less subject to beam loading than the uniform accelerator structure. For an accelerator of given filling time and 20% more."
