Buckling Measurements-Heavy Natural Uranium Tubular Fuel Assemblies

Description: One-region buckling measurements that were made on a series of D/sub 2/O- moderated lattices of heavy uranium metal tubes in the Process Development Pile at Savannah River Laboratory are presented. The purposes of these measurements are to provide normalization points for lattice bucklings and to extend the study of natural uranium- D/sub 2/O systems. The dependence of buckiing on the moderatorto-fuel ratio is studied for two types of lattices. (R.E.U.)

Compounds in the Binary Phase Diagrams of the Monovalent Chlorides With the Multivalent Chlorides

Description: The phase-diagram literature was surveyed to the end of 1960. Information about the binary systems of monovalent with multivalent chlorides was observed. Compounds of double chlorides occurring in these systems are listed in tabular form together with the available structural information. (auth)

Corrosion Experience with Aluminum Powder Products

Description: Extrusions of aluminum alloy powder products were obtained from several sources and evaluated for corrosion resistance to high-temperature (260-- 350 deg C) water. Several types of tubing impact-extruded by ALCOA were tested. The stronger tabing (M655) failed very rapidly. The weaker tubing suffered extensive localized surface attack and penetration of the corrosion attack along the extrusion direction after prolonged ( approximates 3 months) exposure to 290 deg C water. A precorrosion heat tre… more

CRITICAL EXPERIMENT WITH BORAX-V. Internal Superheater

Description: A critical experiment was performed with 12 BORAX-V superheater subassemblies in a central voidable region plus 1228 to 1525 UO/sub 2/ fuel pins (3 wt% enriched) in a peripheral region. Removing water (28% of superheater volume) at room temperature decreased reactivity by 2.2%. The midplane (two- dimensional) peak-to-average power distribution in the voided superheater was approximately 1.24, mostly attributable to flux depressions within insulated fuel boxes. Cadmium ratios are also reported. … more

The Crosscorrelation Method of Measuring System Dynamic Response

Description: The basic relations of the crosscorrelation method are presented; and variations of the method for dealing with practical cases for which the idealized relations are inaccurate due to finite experiment length, finite bandwidth of the input signal, and uncorrelated noise in the system response signal are discussed and demonstrated.

An Evaluation of the Substitution of Zircaloy for Stainless Steel in n.s. Savannah Fuel-Element Containers. Summary Report

Description: The possibility of reducing fuel-cycle costs for the N.S. SAVANNAH by replacing the stainless steel fuelelement containers in the permanent reactor core structure by similar containers of a zirconium alloy was investigated. These containers, although not integral parts of the fuel-bearing components, are located within the active core and divide the core into 32 separate channels into which the fuel elements are placed. Areas of investigation included reactor physics, fuel-cycle economics, mate… more

Intensity of Upward Muon Flux Due to Cosmic-Ray Neutrinos Produced in the Atmosphere

Description: Calculations were performed to determine the upward going muon flux leaving the earth's surface after production by cosmic-ray neutrinos in the crust. Only neutrinos produced in the earth's atmosphere are considered. Rates of the order of one per 100 sq m/day might be expected if an intermediate boson exists and has a mass less than 2 Bev. (auth)

INTERNATIONAL CONFERENCE ON NUCLEAR PHYSICS WITH REACTOR NEUTRONS. OCTOBER 15-17, 1963. A Topical Conference of the American Physical Society

Description: The subject matter is divided into five sections: fundamental properties of neutrons, precision measurements of and experiments with capture gamma rays, neutron cross sections, and fission processes. Of the 52 papers presented, separate abstracts were prepared for 43; 9 were previously abstracted in NSA. (R.E.U.)

MEAN SQUARE VOLTAGE FLUCTUATION MEASUREMENTS WITH NEUTRON-SENSITIVE ION CHAMBERS

Description: The mean square fluctuation voltage in neutron sensitiv ion chambers was measured rather than the d-c current to improve gamma discrimination and eliminate d-c cable leakage interference currents. The circuitry and chambe are described, and performance in the mean square volta mode is compared with that in the d-c current mode. (D.C.W.)

MEASUREMENTS OF BUCKLINGS AND DIFFUSION COEFFICIENT CHANGES IN D$sub 2$O- MODERATED LATTICES OF TUBULAR UO$sub 2$ ASSEMBLIES

Description: Diffusion coefficients and bucklings are measured for UO/sub 2/ fuel tube assemblies in D/sub 2/O moderated lattices. The effects of H/sub 2/O fogs and air in the coolant channels in place of D/sub 2/O are studied. (T.F.H.)

Mechanical Properties of Thin Films. Technical Report No. 29

Description: vention of the Society for Nondestructive Testing. The elastic and plastic properties are reviewed with special emphasis on metal films prepared by vacuum evaporation, although work with both non-metals and other preparation techniques is discussed when it is the only existing data or has particular importance. A definite lack of agreement exists among the various workers and as a result detailed explanations are not possible although general suggestions do exist. The structure of thick polycry… more

Physical Limitations on the Measurement of Transient Fields in Air and in Dissipative Media Using Electric and Magnetic Probes

Description: The properties of electric and magnetic probes for the measurement of transient electromagnetic fields in air and in dissipative media are discussed briefly, It is shown that the effective height of an electrically small loop is independent of the ambient medium. This is also virtually true for a thin electrically short dipole (or monopole). If the open-circuit voltage of a magnetic probe can be measured accurately, it is possible (in principle) to reconstruct the time history of the incident m… more

A PROPOSAL FOR THE Mc$sup 2$ ISOCHRONOUS CYCLOTRON. A GENERAL PURPOSE HIGH- INTENSITY 810-Mev PROTON ACCELERATOR

Description: An isochronous eight-sector proton cyclotron to provide an extracted beam in excess of 100 mu amp at 810 Mev is proposed. The primary proton beam and the secondary meson and neutron beams will be used to investigate nuclear structure and the interactions between elementary particles. Biomedical and space-oriented research programs are also planned. Shielded research areas and an extensive beam transport and analysis system are provided. Theoretical and experimental studies have shown that the M… more
