Preliminary evaluation of 30 potential granitic rock sites for a radioactive waste storage facility in southern Nevada

Description: Results of preliminary study are presented which was performed under subtask 2.7 of the NTS Terminal Waste Storage Program Plan for 1978. Subtask 2.7 examines the feasibility of locating a nuclear waste repository in a granitic stock or pluton in southern Nevada near the Nevada Test Site (NTS). It is assumed for the purposes of this study that such a repository cannot be located at NTS. This assumption may or may not be correct. This preliminary report does not identify a particular site as being a suitable location for a repository. Nor does it absolutely eliminate a particular site from further consideration. It does, however, answer the basic question of probable suitability of some of the sites and present a systematic method for site evaluation. Since the findings of this initial study have been favorable, it will be followed by more exhaustive and detailed studies of the original 30 sites and perhaps others. In future studies some of the evaluation criteria used in the preliminary study may be modified or eliminated, and new criteria may be introduced.

Medium-temperature air-heater development program. Final report, October 1, 1977-December 31, 1978

Description: A program to design, fabricate, and verify by test a low-cost (in volume production), modularized, practical solar air heater adaptable for new or retrofit space-heating and hot-water applications is described. The unique hardware elements of the SOLAIR II medium-temperature air heater described are the TCA solar collectors, energy transfer module, interconnecting ductwork, and mounting hardware. SOLAIR II is a two-tank domestic hot-water-augmented system. The system is described in detail; market and design analyses are described; fabrication procedures are noted; and design verification tests and results are discussed. The design used for the pre-production lot was essentially the SOLAIR II design and will serve as the basis for future design evaluations as the product is introduced into the commercial market.

Advanced subsystems development. Second semi-annual progress report, April 1--October 1, 1978

Description: The concept design for a small (less than 10 MWe) solar thermal electric generating plant was completed using projected 1985 technology. The systems requirements were defined and specified. The components, including an engineering prototype for one 15 kWe module of the generating plant, were conceptually designed. Significant features of the small solar thermal power plant were identified as the following: (1) 15-kWe Stirling-cycle engine/alternator with constant power output; (2) 10-meter point-focusing paraboloidal concentrator with cantilevered cellular glass reflecting panels; (3) primary heat pipe with 800/sup 0/C output solar cavity receiver; (4) secondary heat pipe with molten salt thermal energy storage unit; (5) electric energy transport system; and (6) advanced battery energy storage capability. The present emphasis for achieving cost reduction goals centers on improving conversion efficiency and reducing the cost of key components.

Energy and protein production from pulp mill wastes. Annual report, June 15, 1977--June 15, 1978

Description: Studies on desugared spent sulfite liquor, DSSL, subjected to ozonation indicate that this complex organic substrate in water solution reacts readily with ozone to produce lower molecular weight organic fragments which can be metabolized by a variety of microorganisms. Ozone uptake is complete up to approximately 15 g/l and results in an increase of 35% BOD and a reduction of 16% COD. The production of BOD is pH dependent with a maximum occurring at aroung pH 3. The production of methane via fermentation of DSSL is greatly enhanced by the ozonation reaction. Methane production on raw DSSL is only 45.3 standard cc/1 of DSSL. After ozonation of the DSSL during which 15 g/l of ozone are reacted, the resulting product yields 1239 standard cc/1. The hypothesis that methane is produced from acetic acid, held by several prior workers, could not be corroborated in this study. Liquor remaining in the fermenter after gas production has essentially ceased in much richer in acetic acid than ozonated DSSL. Continuous fermentation studies operated to optimize gas production produced a fermentate containing 3.96 g/l of acetic acid. The production of protein accomplished through the growth of Torula yeast on DSSL is also enhanced by the ozonation reaction. Two variants show minimal growth on unozonated DSSL but cell densities of 5 g/l were obtained with the rough variant when this substrate has been ozonated. In contrast to the methane fermentation which showed high ozone consumption to be beneficial, the yeast prefer very minimal ozone reaction. Yeast growth was not vigorous on methane fermentate shown to be rich in acetic acid.

Energy and protein production from pulp mill wastes. Annual report, September 15, 1978--December 15, 1978

Description: Effort was concentrated during the past quarter to define the extent of biological control necessary to achieve high production rates of methane. Although sustained production rates in excess of 100 cc/hr were consistently obtained in the previous quarter, the fermentation activity decreased with respect to productivity. All efforts during the past quarter proved ineffective in arresting the decline in productivity. Methane production now averaging 20 cc/hr is no better than productivity previously obtained on ozonated SSL with no supplemental methyl alcohol addition being added. Although it is still evident that supplemental methyl alcohol enhances methane production, the rate is now below the satisfactory or expected level. The fundamental conclusion one must draw from this quarter's results is that methane fermentation of simple oxygenated molecules is more efficient and produces a richer off-gas in terms of energy content than the same fermentation conducted on low molecular weight fragments obtained by the ozonation of SSL.

Thin film CdS/Cu/sub 2/S solar cells by chemical spraying

Description: This project involves further work on a process developed to make very thin film CdS/Cu/sub 2/S solar cells. The process is adapted to the float glass process and consists of spraying suitable chemicals on a moving ribbon of glass which floats on a bath of molten metal. The spraying produces the necessary thin films (with suitable optical and electrical properties) of SnO/sub 2/, CdS and Cu/sub 2/S. The CdS films produced are two to three microns thick, thus conserving the use of cadmium. The estimated cost per peak watt is approximately 7 cents (1975 costs) at 5 percent efficiency and an output of 37.6 x 10/sup 6/ square meters annually. The cells are blackwall cells. A float glass plant modified for the process is shown schematically. Research progress is described.

Slag waste heat recovery and utilization in the elemental phosphorus industry. Final report, October 28, 1977--April 30, 1978

Description: Approximately 80 x 10/sup 12/ Btu/y of thermal energy are contained in molten slags produced by the elemental phosphorus industry, the iron and steel industry, the copper industry, and wet-bottom coal-fired boilers. This study evaluates the technical, economic, and environmental feasibility of recovering this wasted energy; the impact of slag waste-heat recovery on the industries in question; and the steps necessary to commercialize applicable heat recovery technology. The study considered two approaches to recovering thermal energy from phosphorus slag: the float chamber and the contact tower. Based on these approaches, nine energy recovery options for converting the energy in slag into other usable forms of energy were conceptualized and economically evaluated. All nine options are considered tecnically feasible and environmentally sound. The economics of the nine options are based on 33.9 kg/s (269,000 lb/h) of slag throughput and vary with both the energy from produced and the realizable total credits for different energy forms. Slag by-product credit is generally needed to make heat recovery economically attractive. Slag waste-heat recovery offers considerable potential for energy savings in the elemental phosphorus, iron and steel, and copper industries. Additional studies are recommended to determine if sufficient by-product credits can be obtained to justify this technology economically.

Heat exchanger method - ingot casting fixed abrasive method - multi-wire slicing. Phase II. Silicon sheet growth development for the Large Area Sheet Task of the Low Cost Solar Array Project. Quarterly progress report No. 4 for July 1--September 30, 1978

Description: Solar cells fabricated from HEM cast silicon have yielded up to 15% conversion efficiencies. This has been achieved in spite of using unpurified graphite parts in the HEM furnace and without optimization of material or cell processing parameters. Molybdenum retainers have prevented SiC formation and reduced carbon content by 50%. The oxygen content of vacuum cast HEM silicon is lower than typical Czochralski grown silicon. Impregnation of 45 ..mu..m diamonds into 7.5 ..mu..m copper sheath has shown distortion of the copper layer. However, 12.5 ..mu..m and 15 ..mu..m copper sheath can be impregnated with 45 ..mu..m diamonds to a high concentration. Electroless nickel plating of wires impregnated only in the cutting edge has shown nickel concentration around the diamonds. This has the possibility of reducing kerf. The high speed slicer fabricated can achieve higher speed and longer stroke with vibration isolation. This machine will be used for slicing 3'' and 4'' diameter workpieces.

Coal feeder survey for Illinois coal gasification group. [Lockhopper, Fuller Kinyon screw, Foster Miller pocket feeder]

Description: An evaluation of three coal feeder concepts (lockhopper, Fuller Kinyon screw and Foster Miller pocket feeder) for use in the ICGG first stage gasifier was made. For the sake of consistency, all feed concepts were evaluated on the same basis, that is, feeding a nominal 100 Tons per hour (TPH) against a back pressure of 50 psig. Also, all feed systems were assumed to have similar atmospheric storage hoppers and final injection systems. Accordingly, no further consideration of these support systems was made. This survey was accomplished by reviewing the literature, interviewing vendors, contacting applicable facilities and performing necessary original analysis. The emphasis of the survey was on the test and industrial experience of each system. The results of this survey which are summarized on Table I show that the lockhopper system still should be considered as the baseline system because it is a proven system with extensive operating experience. On the other hand, if definitive tests can prove conclusively that the Fuller Kinyon screw pump will deliver coal against 50 psig back pressure with acceptable efficiencies and coal particle attrition characteristics, it would be the preferred system because it is the lowest cost and easiest to maintain. The Foster Miller linear pocket feeder is an excellent innovative solution to the coal feeder problem. This design, however, is more suited for use in feeding against much higher pressures than the 50 psig required in this application.
