Mass Transfer Coefficients and Interfacial Area in a One Stage Pulse Column

Description: Over-all mass transfer coefficients were determined independently of the interfacial area by considering the operation of the pulse column to be a stage- wise process. The calculated coefficients describe only the operation of the pulse column for the free rise of organic droplets through a stage, since in the downstroke the aqueous phase passes through the organic phase in the form of rivulets preferentially wetting the plates. The driving force for transfer was based on the aqueous phase conc… more

Flow Properties of Superfluid Systems of Fermions

Description: The nonspherically symmetric solutions to the Bardeen-Cooper-Schrieffer theory are given a physical interpretation in terms of an anisotropic fluid model. These solutions have been used previously to predict a phase transition in liquid by He{sup 3} by Emery and Sessler and Anderson, Morel, Brueckner, and Soda. An investigation of the flow properties of such systems is made that involves the calculation of the effective mass for flow in a straight channel and the moment of inertia of a cylindri… more

The Energy Gap in Nuclear Matter

Description: The magnitude of the energy gap in nuclear matter associated with a highly correlated ground state of the type believed to be important in the theory of superconductivity has been evaluated theoretically. The integral equation of Cooper, Mills, and Sessler is linearized and transformed into a form suitable for numerical solution. The energy gap, calculated by using an appropriate single-particle potential and the Gammel-Thaler two-body potential, is found to be a very strong function of the den… more

Summary statement of findings related to the distribution, characteristics, and biological availability of fallout debris originating from testing programs at the Nevada Test Site

Description: Summary statements are given of significant findings related to the distribution, characteristics, and biological availability of fall-out debris originating from testing programs at the Nevada Test Site during the past decade. The delineation of fall-out patterns has been accomplished by the use of aerial and ground monitoring surveys. Only about 25% of the total amount of fission products produced by tower-supported detonations were deposited within distances corresponding to fall-out time of… more

Some Physics Calculations on the Performance of Large Fast Breeder Power Reactors

Description: Critical mass, spectrum, breeding ratio, and coolant removal coefficients were calculated for a series of large Pu- U/sup 238/-fueled sodium- cooled fast-breeder power reactors, using a new 16-group cross-section set based in pant on recent miscroscopic cross-section measurements. The parameters studied include reactor size, plutonium isotopic content, and type of structural material. Reactors cooled with Pb - Bi eutectic and those contaiing U/sup 233/- Th fuel were examined.

Chemical Problems in Advanced Gas-Cooled Reactors

Description: The chemical problems largely involve gas- and solidphase chemistry where chemical reactions and physicochemical processes occur at elevated temperatures ( approximately 4000 deg F). The high temperatures require that the fuel bodies and moderator be made of refractory materials and may preclude the use of metal cladding. Areas of concern include reactor materials and primary coolant systems, where most of the problems involve mass transfer. Reactions are discussed which can lead to carbon tran… more

Study of Factors Influencing Ductility of Iron-Aluminum Alloys. Monthly Letter Report

Description: The objective of the program is to determine the effect of variations of aluminum content, heat treatment, surface preparation, and other metallurgical factors upon the room-temperature ductility of Fe-- Al alloys. As a continuation of the metallographic deformation studies, two coarse-grained tensile specimens of 13.9-Alfenol were heat treated, electropolished, and pulled to fracture. (W.L.H.)

A Mass-Spectrometric Investigation of Sulfur Vapor as a Function of Temperature

Description: A mass-spectrometric investigation was performed on sulfur vapor in equilibrium with the condensed phase at 120 to 210 gas-cooled C. It was found that, in this temperature range, equilibrium sulfur vapor contains appreciable quantities of S/sub 8/, S/sub 7/, S/sub 6/, and S/sub 5/ only. The sulfur vapor emanated as a small well-collimated molecular beam from a specially constructed source into an ionization chamber which was designed to exclude from analysis any sulfur vapor that had impinged o… more

An Electron Multiplier as a Detector for a Surface Ionization Mass Spectrometer--Design

Description: A description of a 14-stage electron multiplier for use amplifying the detector signals in a surface ionization mass spectrometer is given. The system can either measure the multiplier anode current or count the anode pulses. Pulse counting may be used for- signal currents in the range from lO/sup -13/ to 10/sup -18/ amp. The range of the normal electrometer circuit is extended by the electron multiplier so that it measures currents from l0/sup -10/ to 10/sup -15/ amp with a fast response. (aut… more

FISSION-GAS-RELEASE FROM UO$sub 2$, INTERIM REPORT NO. 1

Description: The evolution of fission products from UO/sub 2/ during irradiation at high temperatures is of primary interest to the Gas-cooled Reactor Project. Fuel tests consisting of UO/sub 2/ pellets encapsulated in Inconel or stainless steel were irradiated in the LITR, ORR, and ETR. The capsules were pierced in hot cells, and the gases collected in evacuated systems. Fractions of this gas, of suitable activity for counting, were taken and then analyzed by gamma spectrometry. Larger fractions of gas wer… more

Study of Real Gas and Heat Transfer Effects on the Design of Hotshot Wind Tunnels

Description: A study of heat transfer in the art chamber and converging section of the nozzle of a "hotshot" wind tunnel was conducted to determine the effects of heat transfer on the performance of this type of wind tunnel at initial are- chamber pressures from 100 to 6800 atm and temperatures from 4000 to 14,000 deg K. Radiation from the hot gas was found to be governed by black-body emission laws for pressures above 100 atm at the temperatures considered. Convection to the throat was evaluated, and it wa… more

FEASIBILITY STUDY OF A NEW MASS FLOW SYSTEM. Quarterly Report No. 1 Covering the Period from June 1 to September 1, 1960. With this is bound: QUARTERLY REPORT NO. 1 FOR PERIOD FROM JULY 15TO SEPTEMBER 1, 1960

Description: A mass flow measurement technique is described which has the capability of measuring homogeneous flow, slurries, highly corrosive fluids, and multiphase fluids. The device features ruggedness and reliability and has the ability to measure external to the flow. In the proposed system, the fluid is made to pass through a U-shaped tube wherein measurements of the augular momentum and density yield mass flow directly. As the fluid traverses the 180 deg bend, a radial force is generated, which can b… more

Fission of Gold With 112-Mev C{sup 12} Ions: A Yield-Mass and Charge- Distribution Study

Description: Fission prcduct cross sections were measured radiochemically and mass- spectrometrically for gold bombsrded with 112-Mev C/sup 12/ ions. Cross sections for 43 nuclides were measured for elements from nickel to barium. Thirty-six yields are either primary fission product yields (independent yields) or were corrected (with less than 25% correction) so as to represent independent yields. The independent yields were empirically systematized and a yield-mass curve was constructed. The yield-mass cur… more
