Development and testing of shingle-type solar cell modules. Quarterly report No. 2

Description: The details of a shingle module design which produces in excess of 97 watts/m/sup 2/ of module area at 1 kW/m/sup 2/ insolation and at 60/sup 0/C are reported. This selected design employs a tempered glass coverplate to provide the primary solar cell structural support. The use of the B.F. Goodrich FLEXSEAL roofing system as the outer skin of the shingle substrate provides a high confidence of achieving the 15 year service life goal.

Literature review of the saturation state of seawater with respect to calcium carbonate and its possible significance for scale formation on OTEC heat exchangers

Description: An investigation of available data on the saturation state of seawater with respect to calcium carbonate and its possible significance for scale formation on Ocean Thermal Energy Conversion (OTEC) heat exchangers has been carried out. Pertinent oceanographic data is lacking at or near potential OTEC sites for the calculation of the degree of saturation of seawater with respect to calcium carbonate. Consequently, only ''extrapolated'' saturation values can be used. These indicate that near surfa… more

Detection and measurement of Post-Rosenbluth convective instability in MFTF with a hybrid CO/sub 2/ laser--heterodyne diagnostic system

Description: To measure and classify the Post-Rosenbluth convective loss-cone instability in MFTF, we propose to use a CO/sub 2/ laser consisting of a TEA-pulsed section and a low pressure CW section, together with a light mixing receiver. Calculations show that this system offers sufficient power and sensitivity to detect instability throughout the range from strong coherent light scattering to weak incoherent scattering when the instability is eliminated.

Improving the performance of brine wells at Gulf Coast strategic petroleum reserve sites

Description: At the request of the Department of Energy, field techniques were developed to evaluate and improve the injection of brine into wells at Strategic Petroleum Reserve (SPR) sites. These wells are necessary for the disposal of saturated brine removed from salt domes where oil is being stored. The wells, which were accepting brine at 50 percent or less of their initial design rates, were impaired by saturated brine containing particulates that deposited on the sand face and in the geologic formatio… more

Powerplant Productivity. Improvement Study: current practices in Illinois utilities towards powerplant productivity. Final report, Project 1, Task 1

Description: Efforts of this task indicate that powerplant productivity is a complex issue that has to take into account economic factors, equipment limitations, and system-loading characteristics as well as external constraints such as regulatory requirements. Among the specific findings are: (1) utilities in Illinois use the industry-wide measures of performance such as capacity factor, availability factor, forced outage rates etc.; equivalent availability as a measure is not in common practice; (2) sever… more

EDOT: a code to calculate charge particle slowing down in a plasma

Description: EDOT is a code that calculates the slowing down of a test particle in a Maxwellian plasma utilizing continuous slowing down theory. Both nuclear scattering and reactions are included. The output includes slowing down parameters as well as spectra of knock-on ions and in-flight reaction probabilities. The theory, input, and output for the code are described.

Powerplant Productivity Improvement Study: benefits of improved powerplant reliability. Final report, Project 2, Task 2

Description: A summary of total cumulative fuel consumption differences by fuel type through 1990 for four improvement scenarios is presented for Commonwealth Edison Company (CE) and for Illinois Power Company (IP). In all scenarios, liquid-fuel consumption is reduced. Generation is shifted to the coal and/or nuclear units for which improved availability has been assumed. For a 2% improvement in both planned (POR) and forced outage rates (FOR), a total of more than 16 million barrels of No. 6 oil will have … more

Conceptual design report for solar production of industrial process steam ranging in temperature from 300 to 550/sup 0/F. Phase 1, September 30, 1978-June 30, 1979

Description: The conceptual design of a solar process steam system began with studies and evaluations of various alternative design configurations. From these evaluations a final candidate design configuration was selected which is to be used for further detailed analysis and engineering. An evaluation of various types of distributed collector systems is presented. Cost-effectiveness of various distributed collectors was determined on the basis of total relative cost (including foundation and installation) … more

Utilization of shale oil as a feedstock for steam pyrolysis and petrochemical intermediate production. Quarterly technical progress report, June-August 1978

Description: During the past quarter, 5 runs were made on a number of hydrotreated samples including a mildly hydrotreated simulated in-situ (1.35% N) and two moderately hydrotreated Tosco II (0.82% N and 1.55% N) distillates. The results are, in general, consistent with previous results which indicated an increase in olefins yield as the severity of hydrogenation increased. The olefins yields for the simulated in-situ oil were greater than those for the Tosco II oil for oil hydrogenated to comparable sever… more
