Abundances and Spectra for Cosmic-Ray Nuclei from Li to Fe For 2to 150 GeV/n

Description: We report measurements of the absolute and relative abundances, differential energy spectra, and spectral indices for cosmic-ray nuclei from Li to Fe for 2 to 150 GeV/nucleon. These measurements were made using a balloon-borne superconducting magnetic spectrometer with scintillators and optical spark chambers. The abundances of Li, Be, and B for rigidities below 10 GV/c are consistent with an energy-independent mean interstellar pathlength of 4 1/2 {+-} 1/2 g cm{sup -2} for all propagation mode… more

Adiabatic surface thermometer for improved production braze quality

Description: An adiabatic surface thermometer was developed to control automatically the critical temperature-time cycle of a production vacuum-brazing process. Investigations revealed that optimum braze-joint strength required precise control of the brazing temperature. Spot-welded thermocouples could not be used because the spot welds cause surface damage. This thermometer touches the surface and uses a differential thermocouple and heater to measure surface temperature without heat flow, thereby eliminat… more

Aerial Radiometric and Magnetic Survey, Tonopah National Topographic Map, Nevada: Volume 1

Description: Abstract: The results of analyses of the airborne gamma radiation and total magnetic field survey flown for the region identified as the Tonopah National Topographic Map NJll-5 is presented in Volume I and II of this report. The airborne data gathered is reduced by ground computer facilities to yield profile plots of the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth… more

Alternative oxide fuel pellet fabrication for irradiation testing. [LMFBR]

Description: Fabrication of experimental breeder reactor fuel pellets by the common cold-press-and-sinter technique for irradiation testing in EBR-II is discussed. Fuel types include mixed thoria-plutonia, UO/sub 2/ enriched with 22 weight percent /sup 233/U in U, UO/sub 2/ enriched with thirty-four weight percent /sup 235/U in U, and mixed urania-plutonia.

Analysis of advanced conceptual designs for single-family-sized absorption chillers. Annual report

Description: The objectives of the research reported is to develop and analyze new concepts for absorption cycles to improve the performance or reduce the cost of a 3-ton absorption chiller that can be used with solar collected heat. New refrigerant-absorbent pairs are investigated, as are additives to currently used refrigerant-absorbent pairs. Results are given of a literature search on those topics. An initial screening is reported to check the values of the heats of mixing of candidate refrigerants and … more

Atomic absorption instrument functional description

Description: This report describes a proposed system for automating atomic absorption analysis. The system consists of two atomic absorption instruments and an automatic sampler that can be attached to either instrument. A computer program controls the sampling and gathers data. The program then uses the data to perform bookkeeping, data processing, and report writing.

Atomic absorption spectrometer readout and data reduction using the LSI-11 microcomputer

Description: Some common instruments found in the chemistry laboratory have analog chart recorder output as their primary data readout media. Data reduction from this medium is slow and relatively inaccurate. This paper describes how to interface a single LSI-11 microcomputer to PERKIN-ELMER models 603 and 303 Atomic Absorption Spectrophotometers.

Availability and reliability improvement program

Description: The goal of TVA's Availability Improvement Program for its fossil-fueled power plants is to increase plant availability from 79 to 83%, to reduce the forced outage rate from 10 to 7%, and to reduce the equivalent outage rate related to forced deratings from 6 to 2%. As background for this program historical data on plant availabilities, trends toward improved availability, factors which contribute to current reliability, and ongoing programs to improve fossil-fueled plant reliability are discus… more

Battery technology - an assessment of the state of the art

Description: A state-of-the-art battery survey and data verification process were conducted with battery manufacturers and organizations involved in battery technology research and development. This report addresses those major battery technologies which were identified as either being developed or explored as potential candidates for major energy storage applications in electric utilities or transportation as well as for future operations with solar or wind energy systems. Near- and far-term battery system… more

Brayton Isotope Power System (BIPS). Phase I. First annual technical report

Description: The objective of the BIPS program is to develop a closed gas turbine dynamic conversion system for space application. The baseline system is a 7-year life, 450 lb, 1300 W(e) unit using Brayton cycle hardware developed for the NASA LeRC and two 2400 W(t) Multi-Hundred Watt isotope heat sources developed for the ERDA. Phase I of the three-phase BIPS program is the conceptual design of the flight system, the design, development, and testing of a prototype Ground Demonstration System (GDS). The Min… more

Brayton Isotope Power System (BIPS). Phase I: Integrated Program Plan (IPP). Report 75-311574A

Description: The government, AIRPHX, AIRLA, and contractor BIPS program coordination efforts are discussed. These coordination efforts are essential for defining program objectives, and achieving these objectives in an efficient manner. The IPP outlines a long range effort intended to: (a) develop end product confidence; (b) identify government and contractor activities pertinent and contributory to BIPS development; (c) recommend government and contractor activities required to ensure BIPS program success;… more

Brine-Steam Properties Computer Program for Geothermal Energy Calculations. [BPROP7 Code]

Description: A computer program called BPROP7 was written to enable the user to obtain conveniently the thermodynamic properties of brine and water vapor in combination, given at least three of nine parameters. The parameters included in this program are two types of salt content, temperature, pressure, enthalpy, entropy, density or specific volume, quality, and amount of superheat.

Chemical explosives fracturing field demonstrations. Final report

Description: Field demonstrations of chemical explosive fracturing stimulation were conducted on 3 noncommercial gas wells. The three gas wells had previously been treated by acid and hydraulic fracturing. They were then subjected to further hydraulic fracturing and following this, approximately 20,000 pounds of PTC-4 explosive was manufactured by pumping in 1370 gallons of oxidizer and 430.4 gallons of fuel. After the explosions, the wells were cleaned out and retested. Some improvement was obtained but th… more
