Alternative economic evaluation measures for solar industrial process heat

Description: The measures most commonly used to assist decision-makers in evaluating the economic merits of solar energy projects are described and compared. An example is given to illustrate the economic evaluation measures and the results are applied to a solar industrial process heat project.

Biological and clinical dosimetry. Progress report, October 1, 1979-September 30, 1980

Description: Several major dosimetric intercomparisons were carried out during the last year. At the National Institute of Radiological Sciences, Chiba-shi and the University of Tokyo, Tokyo, Japan, calorimetric and ionimetric intercomparisons of dose were performed. Similar measurements were also carried out at the Lawrence Berkeley Laboratory, Los Alamos, and Harvard. The measurements of the thermal defect for A-150 plastic were completed and an average value of (4.1 +- 0.3)% was found. Preliminary measur… more

Cadmium sulfide/copper sulfide heterojunction cell research. Final report, February 26, 1979-July 15, 1980

Description: Extensive modifications were made to the multi-source deposition apparatus. These include the installation of a larger vacuum chamber on the existing system. The new chamber provides improved inter-source shielding, an improved substrate mounting and heating system, and a vacuum interlock for introducing substrates. CdS resistivity control by both In doping and off-stoichiometric deposition has been investigated. Indium doping has been achieved both by diffusion from a pre-deposited In layer an… more

Catalytic conversion of oxygenated compounds to low molecular weight olefins. Progress report, March 1, 1980-August 31, 1980

Description: A possible route for producing low molecular weight olefins is to convert synthesis gas to methanol followed by conversion of methanol to olefins in a one-step process. During this report period the reaction apparatus suitable for reaction pressure of 500 to 1000 psig was constructed. A preliminary trial run was performed for the reaction of synthesis gas over an intimate mixture of methanol synthesis catalyst and Zeolon-500 (mixture of chabasite and erionite). The reaction temperature, pressur… more

Characterization of carbonaceous materials using extraction with supercritical pentane

Description: The use of carbonaceous adsorbents is limited by irreversible adsorption of some compounds so the use of supercritical pentane as an extracting solvent was examined. Carbon black appeared to be broken down slowly, but continuously, by the penane. To see if other types of carbon behaved similarly, high purity graphite, technical grade graphites, active carbons, and charcoals were examined. The extracts were characterized by uv spectroscopy, packed column chromatography using flame ionization and… more

Conceptual model for regional radionuclide transport from a salt dome repository: a technical memorandum

Description: Disposal of high-level radioactive wastes is a major environmental problem influencing further development of nuclear energy in this country. Salt domes in the Gulf Coast Basin are being investigated as repository sites. A major concern is geologic and hydrologic stability of candidate domes and potential transport of radionuclides by groundwater to the biosphere prior to their degradation to harmless levels of activity. This report conceptualizes a regional geohydrologic model for transport of… more

Conservation in transportation

Description: A nationwide examination was made of grassroots energy conservation programs related to transportation. Information compiled from civic groups, trade associations, and corporations is included on driver awareness/mass transit; travel; and ride sharing. It is concluded that a willingness by the public to cooperate in transportation energy conservation exists and should be exploited. (LCL)

Development and production cost analysis for subatmospheric Brayton system for Brayton-cycle heat-recovery system, characterization program, Subtask A. 4. 2. 4 of Phase I program plan

Description: This document reports on the cost analysis previously performed for a subatmospheric Brayton cycle system sized to operate off the waste heat of a nominal 200-ton per day glass container furnace. Along with product value and operating costs, the cost data for system components is one of the essential elements required for analyses and prediction of the return-on-investment for a Brayton system. The expected ROI or payback will in turn impact the marketability of the system. This report describe… more

Electric arc radius and characteristics

Description: The heat transfer equation of an arc discharge has been solved. The arc is assumed to be a cylinder with negligible axial variation and the dominant heat transfer process is conduction radially inside the column and radiation/convection at the outside edge. The symmetric consideration allows a simple one-dimensional formulation. By taking into account proper variation of the electrical conductivity as function of temperature, the heat balance equation has been solved analytically. The radius of… more
