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

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

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

A Compilation of Room Temperature and 1200 F Properties of Metallic Materials With Specific Reference to Their Use as Fuel Cladding in Sodium Cooled Thermal Reactors

Description: A compilation is presented of room temperature and 1200/sup o/F properties of a large number of alloys which might be considered for use in a sodium-cooled reactor. Specific consideration is given to the use of such materials as fuel cladding. The arbitrary basis for property comparison is type 304 stainless steel. The study was made of 10 classes of alloys. These alloys are alloy steels, ferritic stainless steels, austenitic stainless steels, iron and iron-aluminum alloys, precipitation-harden… 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.

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

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.

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

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
