Critical Experiments For Reactor Physics Studies

Description: The thermal value of Eta for U233 and U235 has been determined in a series of experiments involving direct comparison of the critical parameters of unreflected homogeneous aqueous solutions of the two isotopes Auxiliary experiments establishing limits of error, testing certain aspects of the theoretical model employed, and experimentally determining the parameters in the critical equation, have been performed.

Attempts to Delineate Inborn Anemias in Mice. Progress Report and Fifth Renewal Proposal, Report Period: January 10, 1959-January 31, 1960. Renewal Period: May 1, 1960-April 30, 1961

Description: During the past year, three papers covering results of a major series of experiments on intergenotype of blood-forming tissue have appeared, demonstrating successful implantation of isologues normal cells in anemic hosts, permanently correcting their genetic defect in hematopoiesis, both with and without irradiation of the host. Heavy host irradiation was shown ineffective as preparations for implantation of homologous cells of widely different antigenic types.

Analog Computer Analysis of the Thermal Behavior of the EDCR Due to Reactivity Accidents

Description: The ORNL analog computer was used to examine one aspect of a safety system for the EGCR. The thermal behavior of the fuel as a result of increases in reactivity at various power levels and gas flows was examined. Safety actions initiated by wither a flux-minus-flow signal or a reactor outlet gas temperature signal were included in simulation.

Atmospheric Tritium Analysis Technical Progress Report No. 2

Description: Following a discussion of various technical improvements in the tritium analysis facility, a summary is given of the tritium content of Chicago precipitation from 18 December 1957 to 15 June 1959. A smooth decay curve was obtained during an undisturbed period of two months following the "Hardtack" weapons tests in the spring and summer of 1958; a residence time for water in the troposphere of 21.0 + 1.4 days is reduced therefrom. Examination of the data following cessation of weapons tests reve… more

Retrodirectors [for] 80" Chamber

Description: Handwritten manuscript. Light from a pt. source enters the chamber, reaches the first surface of the coat hanger, is refracted by the the first surface to an image at the back of the coat hanger, is reflected at the back of the coat hanger, and in returning, is focused back at the original source. Returning light can be sintered by a bubble into a camera lens; however, the camera lens can not see light scattered by a bubble if the light is going toward the coat hanger instead of returning.

Use of Isolated Junction Sheathed Thermocouples for Moderator Temperature Measurements

Description: Two types of enclosed hot junction arrangements are possible with sheathed mineral insulated thermocouples. They are the integral junction and he isolated junction. The integral junction is formed by welding, soldering, brazing or forging the two wires into the end of the sheath. The process forms a good thermal and electrical contact between the three materials.

Preliminary Design Criteria for the Interim Storage of High-Level Radioactive Liquid Wastes

Description: Approximately five years of process improvements, and production line waste handling experience have been accumulated since the newest tank farm, 241-A, was placed into operation. Process improvements and modifications have resulted in waste volume reductions by decreasing the quantity of solids remaining in the liquid wastes from a unit of production. The resulting concentration of fission products has produced mildly boiling solutions in the storage containers permitting further waste volume … more

Flux distribution problems at C Reactor

Description: This report discusses an outbreak of ruptures in January and February, 1960, which motivated serious consideration of ail phases of reactor operation so that a combined efforts to reduce rupture potential might be made. Items investigated include mixer location, gas composition control, rod movement, rod configuration, tube power, and the axial flux profile of the reactor.

Laboratory determination of normal operating flow rates with a flexible outlet connector -- BDF reactors

Description: This report is essentially an addendum, to an earlier report which presented energy loss data for various enlarged outlet fitting assemblies for possible use on the old reactors. The current report presents data for another candidate outlet fitting assembly which would tend to reduce the energy losses in the process tube outlet fittings. This outlet assembly was developed by the Materials Development Operation, IPD. The data show that the flexible connector assembly would result in a 6.9 per ce… 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

π<sup>+</sup>-p ELASTIC SCATTERING AT 310 Mev: PHASE-SHIFT ANALYSIS

Description: A comprehensive phase-shift analysis of {pi}{sup +}-p elastic-scattering data at 310-Mev incident-pion laboratory kinetic energy has been performed. The experimental data utilized include measurements of the differential and total cross sections and of the recoil-proton polarization. The D-wave phase shifts were found to be definitely needed in order to attain an adequate fit to the data. A general search for phase-shift solutions was carried out, using S-, P-, and D-wave phase shifts. One solu… more

π+-P Elastic Scattering at 310 Mev: Recoil-Nucleonpolarization

Description: The recoil-proton polarization in {pi}{sup +}-p elastic scattering at 310-Mev incident-pion laboratory kinetic energy has been experimentally measured at four scattering angles with scintillation counters. Polarization values obtained, related rms experimental errors, and mean center-of-mass recoil angles are: +0.044 {+-} 0.062 at 114.2 deg. =0.164 {+-} 0.057 at 124.5 deg, -0.155 {+-} 0.044 at 133.8 deg, and -0.162 {+-} 0.037 at 145.2 deg. The sign of the polarization is defined to be positive … more

Examination of Components for Crud and Corrosion 1-B Heat Exchanger Handhole Area. Core I, Seed 1. Test Results T-612080

Description: The extent and location of corrosion, crud deposits, and defects in the ends of the 1-B heat exchanger after removing the handhole covers were determined. There was no visual evidence of pitting or corrosion inside the ends of the heat exchanger. A radiochemical analysis of a smear sample taken from the inside of number one handhole showed the presence of the following isotopes- Fe/sup 59/, Co/ sup 58/, s1>s, and Zr/sup 95/. A radiation survey performed in four handholes indicated a maximum lev… more

A Proposal for Criticality Control Measurements Using Pulsed Neutron Methods

Description: Consideration is given to the possibility that in certain types of processing or storage facilities handling enriched fissionable isotopes the pulsed neutron method can give a useful measure of the subcriticality of the system. The proposed method describes how the concentration and multiplication constant are determined for an assembly of unknown concentrations. Such measurements might be undertaken if high levels indicate the possibility of excessive concentrations of fissionable materials. E… more
