The Circular Polarization of Gamma Radiation Following Allowed Beta Transitions

Description: The degree of circular polarization of gamma rays following allowed beta transitions was investigated as a function of the angle THETA /sub beta gamma / between beta-particle momentum and gamma direction and as a function of the energy of the beta particle. The anisotropy of the beta-gamma circular polarization correlation observed for pure Gamow-Teller transitions ( DELTA 1 = 1) is used to determine the validity of C/sub A/' = C/sub A/. The experimental results for Co/sup 60/ and Na/sup 22/ ar… more

Quantitative Determination of Adsorbed Sulfates on Thoria by Means of Infrared Spectroscopy

Description: By utilizing the KBr-disk technique it is possible to apply infrared analysis quantitatively to the determination of species adsorbed from aqueous solutions on solids of large specific area. In this study, adsorption of sulfates on thoria from aqueous sulfate solutions have a characteristic infrared spectrum with absorbance bands occurring at 8.4, 8.9, and 9.6 microns. Absorbance measurements at these wave lengths were precise to 1-2% and were directly proportional to the amount of adsorbed sul… more

Observations on the Method of Hess for Determining Precision Lattice Measurements

Description: The method of Hess for determining lattice parameters and their standard errors from x-ray powder diffraction films was investigated. The equations are applicable to various cameras and crystal systems. The results of a series or computations in which the initial approximations were deliberately varied over wide that for the computation of precise lattice parameters, the initial estimates need not be good. A parameter input value of zero should be avoided, but otherwise almost any value will do… more

Determination of the Zr Corner of the Zr-Fe-Sn System at 0.1 and 0.2% Oxygen Levels. Final Report for December 5, 1957 - December 5, 1958

Description: This program was undertaken to supply fundamental information on the effect of adding 0.1 or 0.2% oxygen on the phase relationships in the Zr-Fe-Sn system in a limited range of dilute alloys. It is of both theoretical and practical interest to learn that oxygen stabilizes not only the g-phase in zirconium but also two intermetallic compounds ZrFe2 and the G-phase, which, chemically, appears to be Zr4Sn with about 8% Fe replacing zirconium, is shown to be stable at 1010 C, and probably also at 1… more

Radiation Chemistry of Organic Substances. Final Report for 1 January 1957 to 31 January 1959

Description: The chemical processing of reactor fuels involves the use of organic substances as extracting agents and as diluents. When most organic substances ae exposed to reactor fuel, radiation damage occurs. The objectives of this project were to provide more information regarding damage to hydrocarbon solvents which are similar to those used as solvents in the Thorex program and to determine if the radiation-damaged diluent has a pronounced deleterious effect upon the extraction process.

The Dielectric Tube Resonator : a Slow-Wave, Open Boundary, Dielectric Resonator for the Generation and Measurement of Millimeter and Sub-Millimeter Wavelength Electromagnetic Radiation. Technical Report No. 2

Description: The yet unsolved submillimeter wavelength problem, namely, providing a source of high-power, coherent, monochromatic signal frequencies in the region 300 to 3000 kmc/s, together with suitable measuring techniques and devices, is considered. The dielectric tube resonator is proposed to deal with this problem. It consists of a hollow, circularly cylindrical tube of dielectric material suitably terminated at its ends by sufficiently large metal end walls and constitutes a slow-wave, open-boundary,… more

Dispersion in Tidal Estuaries

Description: A number of experiments were conducted at Northwestern University with methylene blue tracer to study the influence on the diffusion process of the periodic variations of flow which are characteristic of tidal estuaries. The oscillatory movement of pollutant was also closely studied with an instantaneous injection of radioactive tritium water in the model of the Savannah Harbor. (W.D.M.)

Dispersion of Fluid Flow in Porous Media

Description: This technical report presents the results of an investigation concerned with the phenomenon of dispersion in porous media flow. In the work, major emphasis has been placed on the problem of one-dimensional, longitudinal flow in porous media, from both theoretical and experimental viewpoints. To date, only limited work has been done on the corresponding radial flow problem. The governing differential equation for the dispersion of a fluid transporting a solute as it flows through porous media c… more

Kinetics of the Platinum-Catalyzed Hydrogen Reduction of Aqueous Cobalt Sulfate Ammonium Acetate Solutions

Description: Cobalt sulfate solutions containing ammonium acetate and chloroplatinic acid were reduced by hydrogen in a Pyrex-glass lined autoclave in the temperature range of 170 to 232 C and hydrogen partial pressure range of 115 to 830 psia. The reduction rate was directly proportional to the hydrogen partial pressure and surface area of the Pyrex glass and was independent of the quantity of chloroplatinic acid added initially. Experiments involving the variation of the relative concentration of ammonium… more

Determination of Coefficients of Reactivity. Test Results DL-S-151 (T-550132). Section I. Fourth Performance

Description: The purpose of the test was to determine the temperature and pressure coefficients of reactivity at sere power. The value for the temperature coefficient at the operating temperature of 523 F with 556.6 EFPH plant operation was 2.5 (delta E/F) x 16(-4). The magnitude of the temperature coefficient at the plant operating temperature (523 F) indicated the reactor is very stable during normal operations. The pressure coefficient varied from values of 1.41(deltaE/psig) x 10(-6) at 1437 psig to a.57… more

Description: The purpose of the test was to determine the station operating characteristics during a start-up with all reactor coolant loops initially cold, requiring chemical addition and the turbine cold. The plant was successfully taken from a cold condition to generator synchronizing in accordance with Volume I, Chapter 43, Station Start-up no. 1. Twice during the test malfunctioning equipment delayed the completion of the test. The 1B boiler drum level indication required repair work and the 1D loop wa… more

Technical Report No. 6

Description: The original melting apparatus has been converted from a one-zone to a six zone operation. Another one-zone refiner has been constructed. The experiments that have been performed to date with these two refiners are discussed in the firs two sections of this report. It is pointed out that it appears that zone melting has a limited application for the refinement of KCl and KBr. We are exploring two other means of purification: 1) ion exchange, and 2) distillation. Work on the analysis of the salt… more

Flow Distribution Across the Core. Test Results DL-S-182 (T-550097). Section II

Description: The purpose of the test was to determine the flow mixing characteristics of the lower plenum. Conclusion: Mixing appears to be quite small. The temperature indicated by the thermocouple nearest the cold loop decreased approximately 15 F. The cold loop temperature was 15 below the initial reactor coolant average temperature when the cold loop was places in services. The thermocouple furthest from the cold loop showed little or no change in temperature. The rate of change of reactor coolant tempe… more

Initial Start-Up and Low Power Operation. Test Results DL-S-161 (T-550127). Special Procedure Section 1

Description: The purpose of the test was to determine the Reactor Plant Systems operating characteristics during start-up and in the low power range. The Decay Heat Removal Valve, instead of operating for one hour as called for in the Test Procedure, operated for only six minutes. This was due to the fact that the turbine room basement became filled with steam when the Decay Heat Removal Valve opened. Due to the fact that the valve operated only once, the data therefore includes information for only one loa… more
