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

Diffusion in a Temperature Gradient

Description: To summarize one finds that for diffusion in a temperature gradient by a vacancy mechanism one must have E(M) < E(F). No such restrictions occur for interstitial diffusion. The spatial vacancy distribution is very nearly the equilibrium distribution if dislocations are present. If no dislocations are present then one could obtain E(M) by measurement of the spatial distribution.

Drying of Charcoal Used for Adsorption of Gaseous Fission Products from Homogeneous Reactors

Description: In homogeneous nuclear reactors significant quantities of radioactive inert gaseous fission products must be separated from the fuel solution for disposal. The present disposal scheme, which is employed on the HRT, is to pass the mixture of fission product gases and oxygen through a charcoal adsorption bed. the oxygen passes through the bed relatively un-adsorbed, but the radioactive inert gases are adsorbed and are displaced from the bed bed very slowly giving the gases a much greater residenc… more

Dynamic B and n-Behavior Up to 7600 Gauss in Magnet Model Mark Ii Comparison of Results With Long and Small Grad Coils

Description: "Magnetic measurements were performance at excitation levels ranging from 4000 to 7600 gauss, to study the dynamic behavior of the magnetic and gradient lengths of the CEA magnet sectors. The influence of the proposed metal vacuum chamber on field and gradient was experimentally determined. Results of measurements made with a 26 in. long grad coil and with small circular grad coils are compared. The reliability of the 26 in. long grad coil is demonstrated."

Dynamic Response of Reactor Plant to Load Changes. Section I. First Performance. Core I, Seed 1. Test Results DL-S-251 (T-612390)

Description: The purpose of the test was to determine the responses of the plant when subjected to load transients exceeding the design magnitudes, and to determine the maximum load changes, positive or negative, that the plant can sustain. The reactor plant responded satisfactorily to all load transients. The only limits exceed were the pressurizer high and low level alarm points. The magnitude of the transients and the time required for the plant to return to equilibrium was dependent upon the size of the… more

Effect of Atomic Interaction Potential on Defect Production in Metals

Description: The cascade of displaced atoms in metals, induced by high energy radiation, has been investigated, with the assumption of a screened coulomb interaction between atoms. The problem was treated stochastically on an IBM 650 electronic computer for several different models. The comparison of our results with those for which a hard sphere interaction has been used shows only a slight decrease in the expected number of atomic displacements.

The Effect of Crystallite Size on the Bulk Density and Strength Properties of Uranium Dioxide Specimens

Description: Fused uranium dioxide was separated into fractions of varying particle size by air separation. Specimens of the nominal size of 1/8 by 1/4 by 1½ in. were formed by hydrostatic pressing, firing, and lapping. Specimens prepared from the 0 to 5 μ fraction were the strongest and most dense. The room-temperature density was about 92% of theoretical and the room-temperature flexural strength was about 12,000 1b. per sq. in. When tested at 1000°C., the strength was about 18,000 1b. per sq. in. The fle… more

Effect of Quadrupole Lenses

Description: "The effect of correcting quadrupole lenses on the betatron oscillation characteristics of an AG synchrotron was studied, and general formulas are given for the fractional changes of the amplitude and phase functions. Calculations performed for different setups of different numbers of lenses for the CEA synchrotron structure point out that one may correct for sizable errors in the n- value by means of 8 pairs of quadrupole lenses in two consecutive straight sections with the focusing lens betwe… more

Effects of Ultraviolet Radiation on Chloroplast Reactions and Plant Metabolism

Description: This technical report represents a brief survey of work by this project on the effects of ultraviolet radiation (UV) on certain of the photochemical and metabolic properties of rhubarb chard and sugar beet (Beta vulgaris). These plants were selected for this work because for some years they have been used as sources of chloroplasts for Hill reaction studies in this laboratory. Some of this work has appeared as a brief paper.

Effects of X-Irradiation on the Plasmas of Chickens as Revealed by Serological Analysis. Part I, Whole Plasma Comparisons. Part II, Alteration of Proteins of the Liver (a Preliminary Report). Part III, Autoantibody Formation (a Preliminary Report)

Description: Irradiation of a living animal with X-rays induces alternation in the proteins of cells in which ionization events occur. Systematic end-products such as the proteins of plasma would, by changes in quality and quantity divulge modification of their synthetic pathways, or compensatory responses of the hematopoietic systems to stresses caused by irradiation in other organs. Serological identification of proteins, a sensitive means of biochemical characterizations was chosen to reveal variations i… more

Elastic Scattering of Protons and Neutrons by Deuterons

Description: "It is shown how a momentum space formulation of the p-d and n-d scattering problem makes possible a good calculation of the no polarization approximation. Calculations are carried out for a central Yukawn shaped Serber potential for values of the angular momentum L-o-6 in the energy range 0-95 Mev. These show that Born's approximation is not a good approximation at any energy, even for L-3. It is shown that a Fredholn approximation reproduces the results of the no polarization approximation fo… more

Electrical and Optical Investigation of Charge-Carrier Trapping in Rutile Single Crystals

Description: "Low-frequency absorption centers, observed by electrical measurements in single crystals of rutile, can be produced by thermal quenching or optical irradiation in the edge of the eigen absorption region (600 A). They are observed when electric fields are applied parallel to the optic axis (crystallographic c axis) and are not visible with the field perpendicular to this axis. The temperature dependence of the principal dispersion indicates an activation energy of 0.18 ev. The centers can be ex… more

The Electrochemical Theory of Smelting and Related Reactions

Description: In this paper we are concerned with the potentials and electrical currents flowing at an interface between two phases as a result of chemical reactions which promote selective ion migration. Although our immediate concern is an explanation of the available results on smelting, a sufficiently broad understand requires that we go far beyond this limited results and bring together the findings from many related fields. We first must consider the diffusion of particles across an interface, which fo… more

The Electronic Energy Levels and the Mass Spectrum of Methane

Description: Recent instrumental developments and theoretical speculation have indicated a need for more information concerning the excited electronic states of polyatomic molecules and ions in the elucidation of mass spectra. A theoretical description of these states is necessary for the proper interpretation of existing data and in laying a firm basis for the planning of future experiments. For the above reasons the energies of a number of the excited electronic states of methane have been calculated in a… more

Emission Rate of Fission Products from a Hole in the Cladding of a Reactor Fuel Element

Description: It is assumed that when a hole appears in the cladding of a reactor fuel tube the fission products in the space between the fuel and the cladding will diffuse towards the hole. There they are swept away by the flow of steam past the hole. The process of diffusion is assumed to be governed by the ordinary diffusion equation with the boundary condition that the density of the fission products is zero at the surface of the hole. The diffusion equation is solved for the case of steady-state emissio… more
