Due to the decreased supply of petroleum and the large quantity of import oil, there exists sufficient economic justification to develop a biomass-liquid fuel industry. Geothermal energy uniquely fits the biomass production and conversion requirements. To accelerate industrial development of biomass-to-liquid fuel conversion using geothermal energy, a national program is required. Because of the INEL's unique experience in moderate-temperature geothermal applications, they should take the lead in this program. Based on an extensive survey of the biomass conversion field, areas of needed work were identified and a program plan was developed. This plan separates the INEL role into two parts. (1) Commercial Support--Existing technology can be commercially applied to provide a portion of the liquid fuel needs. To accelerate development, INEL needs to provide technical and management support to existing programs such as direct assistance, loan guarantees, PONs, and PRDAs. (2) Technical Development--Application of new geothermal technology in the production and conversion of biomass can increase the quantity of domestically produced liquid fuel. The program plan identifies needed work down to the task level. Three cost account levels are identified: (1) Biomass-to-Liquid Fuel Technology, (2) Biomass-to-Liquid Fuel Advanced Technology Demonstration, and (3) Biomass-to-Liquid Fuel Commercial Support. The end item is …

This report discusses the ramifications of President Jimmy Carter's production and deployment decisions of enhanced radiation weapons.

Inorganic analysis of solid, liquid and gaseous samples from the Paraho Semiworks Retort was completed using a multitechnique approach. The data were statistically analyzed to determine both the precision of each method and to see how closely the various techniques compared. The data were also used to determine the redistribution of 31 trace and major elements in the various effluents, including the offgas for the Paraho Retort operating in the direct mode. The computed mass balances show that approximately 1% or greater fractions of the As, Co, Hg, N, Ni, S and Se are released during retorting and redistributed to the product shale oil, retort water or product offgas. The fraction for these seven elements ranged from almost 1% for Co and Ni to 50 to 60% for Hg and N. Approximately 20% of the S and 5% of the As and Se are released. The mass balance redistribution during retorting for Al, Fe, Mg, V and Zn was observed to be no greater than .05%. These redistribution figures are generally in agreement with previous mass balance studies made for a limited number of elements on laboratory or smaller scale pilot retorts. 7 tables.

Heat engine/electric hybrid vehicles offer the potential of greatly reduced petroleum consumption, compared to conventional vehicles, without the disadvantages of limited performance and operating range associated with pure electric vehicles. This report documents a hybrid vehicle design approach which is aimed at the development of the technology required to achieve this potential, in such a way that it is transferable to the auto industry in the near term. The development of this design approach constituted Phase I of the Near-Term Hybrid Vehicle Program. The major tasks in this program were: mission analysis and performance specification studies; design tradeoff studies; and preliminary design. Detailed reports covering each of these tasks are included as appendices to this report. A fourth task, sensitivity studies, is also included in the report on the design tradeoff studies. Because of the detail with which these appendices cover methodology and results, the body of this report has been prepared as a brief executive summary of the program activities and results, with appropriate references to the detailed material in the appendices.

The YMCA Geothermal Heating project proposes to obtain approximately 57% of the total facility energy usage through direct application of the Klamath Falls KGRA. This will be accomplished through the design and construction of a retrofit and injection system for the utilization of an existing 110/sup 0/F geothermal energy source at the project site. The existing 2016 foot well will be outfitted with a turbine pump with variable speed drive. The well head will be enclosed by a 10' x 10' building. The geothermal fluid, pumped at a peak rate of 350 gpm will be transported to the YMCA Facility through 5'' diameter schedule 40 black iron pipe fitted with victaulic couplings for expansion. All underground supply pipes will be equipped with magnesium anodes for galvaic protection and will be insulted with 1'' thick calcium silicate insulation, with two layers of 45 number roofing felt applied with asphaltic compound. All supply lines within the building will be insulated with 1'' fiberglass insulation material with a cloth jacket. The fluids will pass through a heating coil and heat exchanger system to provide heat for the 30,000 square foot YMCA facility as well as for the 90,000 gallon swimming pool. The spent …

A thorough account is given of a solar pond study underway at the University of New Mexico since 1975. This report consists of the Ph.D. dissertation of Federica Zangrando entitled Observation and Analysis of a Full-Scale Experimental Salt Gradient Solar Pond. The stability condition for a non-constant gradient, doubly-diffusive system is derived and a prescription for the routine detection of potential instabilities is presented. Techniques for handling unstable regions are described. Conclusions so far strongly support the viability of the solar pond concept. Salt gradient ponds appear to have a very definite niche in the ecology of energy production.

The tests were performed on a module used on the early demonstration projects. A current production module is undergoing tests with results to be in a subsequent report.

The Tokamak Fusion Test Reactor (TFTR) vacuum chamber cover is sealed by 0-rings without the aid of mechanical fasteners. Under vacuum loading and component weights, the edges lifted no more than 0.005 in. (by a SAP4 computer code analysis). This report explains the model used for this investigation and, in addition, shows the maximum deflection expected at the center of the cover is less than 0.047 in. Also, no stresses are expected to exceed 13,700 psi.

An existing time-dependent numerical model (OGRE) has been modified to examine the time frames associated with repressuring the formation rocks surrounding a generic nuclear waste repository following the operational period when wastes are being stored. The model is two-dimensional in the vertical plane, and assumes that the entire regime is saturated, but the repository is at one atmosphere during the operational period. For the physical and geometric parameters assumed, the results of a simulation of the time necessary to repressurize the formation after the operational period was 421.5 years. These results were in close agreement with a steady-state calculation performed by Golder Associates, Inc., in 1977. The fact that the time-dependent model results were close to the steady-state calculation resulted from the use (in the model) of a very small compressibility value, which caused the simulation to reach a steady-state condition in a relatively short time. Based on these studies, the magnitude of the system (water plus matrix) compressibility is of great importance in determining whether the time for repressurization can be determined from analytical methods or requires the use of a time-dependent numerical model.

Motorola's low cost poly silicon program is described. In the process, SiF/sub 4/, a low cost by-product is reacted with mg silicon to form SiF/sub 2/ gas which is polymerized. The (SiF/sub 2/)/sub x/ polymer is heated forming volatile Si/sub x/F/sub y/ homologues which disproportionate (C.V.D.) on a silicon particle bed forming silicon and SiF/sub 4/. During the initial phases of the investigation the silicon analysis procedure relied heavily on S.S.M.S. and E.S. analysis. This analysis demonstrated that major purification had occurred and some samples were indistinguishable from semiconductor grade silicon (except possibly for phosphorus). However, more recent electrical analysis via crystal growth reveals that the product contains compensated phosphorus and boron. Work on the control or removal of the electrically active donors and acceptors could yield a product suitable for solar application. The low projected product cost and short energy payback time suggest that the economics of this process will result in a cost less than the J.P.L./D.O.E. goal of $10/Kg (1975 dollars). Finally, assuming a successful demonstration of a pilot facility, the process appears to be readily scalable to a major silicon purification facility as was proposed by Motorola and R. Katzen.

The flash-steam conversion cycle is most suitable for electric power production at the SSGF. However, large-scale development of the SSGF may require use of makeup water supplements to injected brine for a viable reservoir pressure maintenance program. Since steam condensate will probably be required to satisfy power plant cooling needs, local surface waters have been evaluated for their potential use as sources of injection makeup. It was found that direct injection of untreated makeup water is not feasible because of high suspended solids loading and potential incompatability problems. However, mixtures of ambient temperature makeup water and higher temperature (80 to 90/sup 0/C) brine effluent, in a 1:4 mass ratio, are potentially injectable following processing by reaction clarification and granular media filtration.

This report reviews results from early electron-beam heating experiments and more recent basic beam-plasma physics experiments as well as present theoretical understanding. We find tha rather simple electron-beams could be employed on the Tandem Mirror Experiment (TMX) at Lawrence Livermore Laboratory to carry out electron heating experiments.

The EQ3/EQ6 software package contains two computer codes (EQ3 and EQ6) and data files which form a useful tool in modeling precipitation from geothermal fluids caused by heating or cooling. The data files contain information on 140 aqueous species and nearly 150 minerals, and permit calculations over the temperature interval 0 to 350/sup 0/C. Assumption of homogeneous thermodynamic equilibrium in aqueous solution permits calculation of the driving forces for precipitation as measured by the affinity (log Q/K) for each such reaction. Further assumption of precipitation and heterogeneous equilibrium for any mineral whose affinity would otherwise exceed a value of zero permits determination of the identity of the precipitates, their masses and volumes, and the temperature ranges in which they form. The EQ3/EQ6 capability was used to determine the effects of temperature increase on formation of precipitates form Salton Sea water.

A laboratory stainless steel reactor has been constructed and installed to study the hydrogenation of SiCl/sub 4/, 3 SiCl/sub 4/ + 2 H/sub 2/ + Si in equilibrium 4 SiHCl/sub 3/. The pressure reactor is designed to operate at pressures up to 500 psig and at temperatures up to 600/sup 0/C. After pressure and leak tests, the apparatus was started-up for the hydrogenation experiments. Temperature and flowrate measurements were calibrated. A safety review showed that the apparatus functioned smoothly and satisfactorily as designed. Experiments on the hydrogenation of SiCl/sub 4/ were carrried out during the last two weeks of September. A series of experiments on the hydrogenation of SiCl/sub 4/ was carried out at reactor pressure of 300 psig and 500 psig. Reaction temperature varies from 450/sup 0/C to 550/sup 0/C. Some preliminary reaction kinetic data and equilibrium data were collected. More hydrogenation experiments are in progress.
