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

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.

A Sensitive Radiation Monitor for a Large Laboratory Area

Description: An instrument has been built to survey releases of radioactivity within the 22-acre enclosure of the Savannah River Laboratory. The device consists of a 2-in.diameter x 2-in. sodium iodide scintillation crystal with associated detector counting and recording circuits which provide a permanent record of radioactivity movements within the Laboratory area. The monitor detects signals of 6.9 mu r/hr from a 0.48-curie cobalt-60 source located 265 ft away. (auth)

ROUTINE TESTING AND CALIBRATION PROCEDURES FOR MULTICHANNEL PULSE ANALYZERS AND GAMMA-RAY SPECTROMETERS

Description: Procedures for the routine calibration of gamma-ray scintillation spectrometers and multichannel pulse-height analyzers are presented. A scintillation spectrometer, designed for use of recently developed computer data processing techniques, is described. The performance specifications required of all electronic components in this application, particularly the performance specifications for multi-channel pulse-height analyzers, are treated; and simple tests are described for determining the perf… more

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

THE SLUG-ANNULAR FLOW REGIME TRANSITION AT ELEVATED PRESSURE

Description: The annular slug flow regime has been investigated in vertical upflow without heating through the use of an electrical conductivity probe. The Teflon cladding and seals of the probe were found to work to at least 488 deg F. When the inlet velocity was sufficientiy high, the quality at transition was found to be a constant for each pressure going from 8.6% at215 psia to 17.6% at 615 psia. No fully developed bubbly flow was observed. (auth)

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)

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

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)

Swelling of Aluminum-Clad Aluminum-Plutonium Alloys on Postirradiation Annealing. Final Report

Description: The changes in density and hardness as a result of annealing at temperatures up to 600 deg C are reported for and aluminum-clad Al-5 wt% Ra andd Al-10 wt% Pu alloy in which 89.3% andd 75.6%, respectively, of the plutonium atoms were fissioned. The density of the irradiated specimens at room temperature decreased after pulse anneals of 15-min duration at temperatures above 525 deg C, whereas for lower andnealing temperatures the density of the specimens increased. The hardness of the specimens a… more

A Proposal for the Mc2 Isochronous Cyclotron: A General Purpose High-Intensity 810-MeV Proton Accelerator

Description: Abstract: "The Oak Ridge National Laboratory proposes to build an isochronous eight-sector proton cyclotron to provide an extracted beam in excess of 100 A at 810 MeV. 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… more
