This is the eighth quarterly technical progress report for a program in which the objective is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. The current Phase IV carries the program through prototype fabrication and bench, engine, and vehicle tests. The final program objective is a detail drive system design and a demonstrated overall vehicle fuel savings potential. The major technical accomplishments during this reporting period were: the test vehicle was successfully driven to and from Ann Arbor, Michigan from Phoenix with the drive system installed; accessory drive hardware was calibrated, disassembled and reviewed for wear after round trip from Phoenix to Ann Arbor, Michigan; MADS governor performance was analyzed and parameters were varied to demonstrate flexibility available in modifying accessory drive input/output characteristics; and a task list that matched smaller, lower cost accessory components, with the accessory drive equipped vehicle, was prepared. Major emphasis during the remainder of the program will be in this area. (LCL)

The objective of this research program is to investigate the technical and economic feasibility of producing solar-cell-quality sheet silicon. We plan to do this by coating one surface of carbonized ceramic substrates with a thin layer of large-grain polycrystalline silicon from the melt. During the quarter, significant progress was demonstrated in several areas: (1) a 10-cm/sup 2/ cell having 9.9 percent conversion efficiency (AM1, AR) was fabricated; (2) the Honeywall-sponsored SCIM coating development succeeded in producing a 225-cm/sup 2/ layer of sheet silicon (18 inches x 2 inches); and (3) 100 ..mu..m-thick coatings at pull speed of 0.15 cm/sec wer$obta9ned, although apoproximately 50 percent of the layer exhibited dendritic growth. Other results and accomplishments during the quarter are reported in detail. (WHK)

The Gulf Management Sciences Group (GMSG) in Pittsburgh was asked to provide assistance in performing a confidence analysis for the SRC-II demonstration plant as required by the Department of Energy. Specifically, the contract says to discuss confidence levels for plant operating and capital costs; plant operability and technical risk. It was decided that the best way to obtain estimates for these variables would be through interviews of people with substantial experience in the field. Each subject was first asked what modifications he envisioned being made to the current plant design. Discussion was limited to major systems that might require partial redesign and comments concerning the plant in general. The interviewees were next asked to estimate the probability of success for the project, given that the modifications they envisioned were in fact made. The modes of the combined distributions of the interview results indicate that the respondents in general felt that the base case estimates represented the most probable outcomes with the possible exception of the capital cost estimate. On the other hand, the respondents consistently judged that there is a chance that the demonstration plant will perform significantly worse than the base case for each of the variables that were …

Results are presented of an investigation of biomass-derived fuels from grasses and grains. A region-by-region analysis of biomass production, with both the present (near-term) and the future (mid-term) being considered is presented. The overall approach for analysis of the near-term involved least cost analysis of production, transportation, and energy conversion. The mid-term analyses were structured around the assumed implementation of modified crop production systems in which land was more extensively used in a given region, improved crop management practices were used, and the crop mixes were significantly altered from the present. The production systems in the several regions were combined with conversion plants ranging in size from 500 oven-dry (OD) tons/day to 3000 OD tons/day, or an energy imput of 75 x 10/sup 8/ Btus to 45 x 10/sup 9/ Btus using 7500 Btus/lb. The conversion processes consisted of anaerobic digestion, fermentation, direct combustion, and thermochemical conversion. The latter process was also considered in the context of production of ammonia and methanol.

The thermal-hydraulic analyses presented in this report are based on application of the subchannel concept in association with the use of bulk parameters for coolant velocity and coolant temperature within a subchannel. The interactions between subchannels are due to turbulent interchange, pressure-induced diversion crossflow, directed sweeping crossflow induced by the helical wire wrap, and transverse thermal conduction. The FULMIX-II computer program was successfully developed to perform the steady-state temperature predictions for LMFBR fuel assemblies with the reference straight-start design and the advanced wire-wrap designs. Predicted steady-state temperature profiles are presented for a typical CRBRP 217-rod wire-wrapped assembly with the selected wire-wrap designs.

An attractive route for producing ethylene and propylene from coal is to gasify the coal to produce synthesis gas, convert the synthesis gas to methanol, and then convert methanol to the olefins. During this report period the reactions of methanol over chabazite ion exchanged with rare earth chlorides have been studied at reciprocal liquid hourly space velocities of 1.5 to 15, at temperatures of 259, 271, 304, 352, and 427/sup 0/C, and at pressure 2.7 atm. At 259 and 271/sup 0/C the principle product was dimethyl ether. As the temperature was increased the conversion of methanol to olefins and alkanes increased to 54% and 32%, respectively. A mixture of dimethyl ether, water, and methanol was fed to the Berty reactor. This mixture was near the equilibrium concentrations for converting pure methanol to dimethyl ether and water at 275/sup 0/C. The Berty reactor temperature was 427/sup 0/C. Initially the yields were similar to those obtained when feeding pure methanol. However, the catalyst activity decreased at a faster rate. Rate models are being developed to correlate the catalyst activity and rate as a function of time on stream and partial pressures. A promising model is presented.

All-vacuum sputter deposited heterojunction solar cells of the CdS/Cu/sub 2/S and Cd/sub 1-x/Zn/sub x/S/Cu/sub 2/S types have been fabricated on glass substrates by dc reactive sputtering using cylindrical-post magnetron sputtering sources and Ar-H/sub 2/S working gases. The rear electrode is Nb. The top grid electrode is Au sputter deposited through a mechanical mask. Preliminary measurements on nonoptimized cells have yielded efficiencies of about 0.4% with short circuit currents of about 3 mA/cm/sup 2/, open circuit voltages of about 0.35V and fill factors of about 0.37. Extensive modifications are being made to the deposition apparatus which will permit greater control over the process variables and optimization of the cells. A series of experiments are reported which indicated that at the high deposition temperatures used for the Cd(Zn)S deposition (approx. 300/sup 0/C), an electrically active impurity, capable of influencing both the series resistance and the junction behavior of the cells, may pass from the Nb into the Cd(Zn)S.

This report is the second of a two-volume documentation of sensitivity analysis of project appraisal variables. The variables analyzed consist of various direct and indirect inputs to the project appraisal methodology (PAM) used by the Division of Fossil Fuel Utilization within the US Department of Energy (DOE) for annual assessment of its research and development projects. In 1979, sixteen division projects were assessed using PAM. Nine input variables were selected for analysis following the 1979 application of the methodology. Six of these inputs were considered to be key variables and are analyzed in Volume I of this report. The remaining inputs were termed additional variables and are reported on in this second volume. The additional variables are: market potential/rate of growth; market score rates; and energy benefits weights and types. The sensitivity analysis results indicate that changes in additional variables do not effect major changes with the exception of the no growth market potential scenario. The results of this study indicate that the PAM is relatively insensitive to small changes in input values. This confirms the validity fo PAMs structure.

An approach for the research effort required to meet the program objective is described, leading to an outline of nine tasks comprising the planned program. Results of effort applied to tasks during the first quarter effort are described. Highlights include fabrication and evaluation of cells in Mo foil substrates, a new chemical etch method which may allow easy, rapid determination of CdS grain diameters in films, and preparation and preliminary evaluation of cell structures on single crystal CdS substrates. Several problems will require special effort in the future: poor adhesion of CdS film to Zn-plated Cu foil substrates and a high incidence of film defects attributed to particle spatter from the CdS evaporation source.

Approximately 2,000 acres of land in the center of the Hanford Reservation is contaminated with an estimated 14 Ci of /sup 137/Cs and 81 Ci of /sup 90/Sr associated with animal wastes. Approximately half of this activity is located on (or within) 2.5 centimeters of the ground surface. The source of the contamination was the B-C Cribs and trenches which were used as liquid radioactive waste disposal sites during the 1950's. The mechanism for movement of radionuclides from the disposal site to the ground surface is believed to have been burrowing by an animal (probably a badger) followed by use of the exposed material as a salt lick by rabbits and other animals. When the radioactivity was discovered, the burrow was sealed, the contaminated site was classed as a radiation zone, and surveillance initiated. The contamination site has not been a significant hazard to employees at the plant or to the public. The Atlantic Richfield Hanford Company maintained control over the surface contamination by isolation, zoning, and by continued surveillance. Methods of handling the contaminated area have been considered. Discussions of these alternatives and applicable safety analysis information are included in this document.

Southern Union Refining Company's Famariss Energy Refinery has worked diligently with Monument Solar Corporation in the conceptual and detail design for this unique application of solar generated steam. An area closely adjacent to the refinery and fronting New Mexico State Highway No. 18 has been designated for the solar collector array. Space planned for the demonstration parabolic trough array is sufficiently large to handle an array of 25,200 square feet in size - an array more than twice the size of the 10,080 square feet proposed originally. The conceptual design, performance, safety, environmental impact, and economic analysis are described. Engineering drawings are included. (WHK)

Development effort has been applied to front junction and back surface field region formation and to high speed application of AR coatings to ribbon material. Effects on cell performance of various surface preparation procedures for web silicon material have also been studied. Ultrasonic seam bonding of foil interconnects to cell metallization has been identified as a potentially higher throughput, lower cost method of interconnection than producing discrete bonds. Collecting junctions have been made in wafer cells using reagent grade POCl/sub 3/, containing titanium at the 20 ppMa level, and in such material doped with Ti to the 100 and 500 ppMa levels using TiCl/sub 4/. No electrical effect of Ti doping was detected. Cells with boron diffusions made from boron-doped glasses deposited in a Silox reactor have shown back surface field action to that in cells using glasses formed in a cold wall horizontal reactor. Antireflection coatings of TiO/sub 2/ in the 600 A range of thickness have been prepared by pulling from liquid precursor solutions at speeds ranging to 40 ft/min. Speeds above 10 ft/min are considered necessary for high throughput processing of continuous ribbon silicon. At 25 ft/min, the contribution to selling price of this process is estimated …

Progress in setting up a remote data entry system for monitoring and recording electric power usage in selected commercial buildings in California is reported. This monitoring presents the 5 and 15-min KWH demand totals for each building or of the entire system. The data will be used to analyze the energy conservation potential and socio-economic impacts of electric power load-leveling strategies. (LCL)
