A cold-flow model is being built to gather information for appropriately designing the venturi and the bottom section of the gasifier to attain the required ash discharge rate in the demonstration plant. Ancillary tasks will investigate the effect of different feed locations and different means of injecting fines. A model is necessary because the operating conditions of the pilot plant gasifier do not permit the type of testing required to meet the above objectives. The pilot plant gasifier has been operated with 2 and 3 in.-diameter venturis. Discharge rates through the venturi appropriate to the feed rates used have been on the order of 100 lb/hr. The demonstration plant design calls for a total ash agglomerate discharge from each gasifier of approximately 10,000 lb/hr. Scaling up venturi sizes and discharge rates from the pilot plant to the demonstration plant level is a primary motivation for building a cold-flow model. Larger sized venturis will be necessary to handle the larger discharge rates, and the model will be capable of incorporating up to an 8-in.-diameter venturi or other multiple-discharge nozzles. All equipment in the cold model will be capable of operation at 200 psig, which will enable testing to be conducted at …

A program for the development of liquid-metal plasma valves (LMPVs) is discussed in detail. The program consisted of two tasks. The first was the development and testing of valves in the laboratory and the fabrication, instrumentation, testing and in-service operation of two valves at the Bonneville Power Administration (BPA) facilities of the Pacific Intertie HVDC Power Tansmission System at Celilo, Oregon. The second task was the design, development, fabrication, installation, and operation of a voltage and current monitoring station and the transient event recording system to go with it. Information is present on the design and development of converter valves; LMPV principles; and the testing of prototype valves. (LCL)

Initial efforts to develop, test, and evaluate counterflow recuperator designs are reported for the High Temperature Range Recuperator project. Potential materials to withstand glass furnace exhaust environments at temperatures up to 2800/sup 0/F were evaluated on the bases of material properties, fabrication capability, and relative performance in the flue environment of a day tank glass furnace. Polycrystalline alumina (Vistal), reaction sintered silicon carbide (KT and NC 430), chemically vapor deposited silicon carbide (CVD) and sintered alpha silicon carbide proved most satisfactory in the material temperature range of 2300/sup 0/F to 2800/sup 0/F. Relatively pure alumina (AD 998 and AD 94), mullite and cordierite were most satisfactory in the material temperature range of 1700/sup 0/F to 2300/sup 0/F. Recuperator designs were evaluated on the bases of cold air flow tests on laboratory models, fabricability, and calculated thermomechanical stress under expected operating conditions. Material strengths are shown to be greater than expected stresses by factors ranging from 2.6 for KT silicon carbide to 16 for cordierite. Recuperator test sections were fabricated from KT silicon carbide and subjected to thermal stress conditions in excess of twice the expected operating conditions with no deterioration or failure evident. A test section was subjected to the …

Experimental and analytical techniques are described which permitted recalibration of the P-2 chamber's monoenergetic sensitivity based upon combined responses from a set of bremsstrahlung measurements, monoenergetic isotopic source measurements, and a monoenergetic gamma radiation produced by inelastic proton scattering. A novel technique is described for combining simultaneous knowledge of bremsstrahlung and monoenergetic response measurements with a statistically determined least structures constraint. The experimental details, analytical procedures, and resulting calibration of the standard P-2 ionization chamber from 100 keV to 20 MeV are presented and compared with previous determinations of the P-2 chamber sensitivity. Differences of approximately 15% between the derived sensitivity and the previously accepted values were observed in the region between 1.5 and 6 MeV.

The full potential for electric load management was determined with respect to the industrial sector by adopting direct load management techniques. Certain options available to regulatory authorities and individual utilities to conserve energy are highlighted. By conducting a demonstration project on a representative sample of primary industrial customers, information could be obtained on the potential impact of direct load management methods and other end-use conservation programs on a system-wide basis or multi-system-wide basis. The study was conducted by the Michigan Public Service Commission in cooperation with the Detroit Edison Company.

Plans are presented for insolation testing of a full-scale test receiver panel and supporting hardware which essentially duplicate both physically and functionally the design planned for the 10 MWe pilot plant. Testing includes operation during normal start and shutdown, intermittent cloud conditions, and emergencies to determine the transient and steady state operating characteristics and performance under conditions equal to or exceeding those expected in the pilot plant. The effects of variations of input and output conditions on receiver operation are also to be investigated. A brief description of the pilot plant receiver subsystem is presented, followed by a detailed description of the receiver assembly to be tested at the Solar Thermal Test Facility.

Historical data from the EEI, FPC, NRC, FEA, and participating utilities were evaluated for each of the four reliability and efficiency indices recommended to the California Energy Commission. Data were not available for all unit sizes for the full period 1971 to 1975. However, the available data were analyzed to arrive at historical averages and ranges of averages for each of the recommended indices. Feasible ranges and averages of each index for units of different sizes and fuel types are presented and trends for each index are discussed with respect to characteristics such as unit age, maturity, equipment problems, etc. The recommended application of these data to the power plant Reliability and Efficiency Guidelines are discussed in the main body of this report (Section B).

The Boeing heliostat design can be produced and installed for a Capital Cost of $42 per square meter at high commercial plant quantities and rates. This is 14% less than the DOE cost target. Even at a low commercial plant production rate of 25,000 heliostats per year the Capital Cost of $48 per square meter is 2% less than the cost goal established by the DOE. Projected capital costs and 30 year maintenance costs for three scenarios of production and installation are presented: (1) commercial rate production of 25,000, 250,000, and 1,000,000 heliostats per year; (2) a one-time only production quantity of 2500 heliostats; and (3) commercial rate production of 25,000 heliostats per year with each plant (25,000 heliostats) installed at widely dispersed sites throughout the Southwestern United States. These three scenarios for solar plant locations and the manufacturing/installation processes are fully described, and detailed cost breakdowns for the three scenarios are provided.

The gathering of demographic, community development, and economic data for the region impacted by the Pikeville (Ohio) Nuclear Enrichment Facility is described. These data are to be used for establishing possible community uses, e.g., space heating, domestic water heating, and industrial uses, of waste heat from the facility. It was concluded that although the economic feasibility of such waste heat utilization remains to be proven, the community would cooperate in a feasibility demonstration program. (LCL)

Core hole DC-6 was completed in May 1978 by Boyles Brothers Drilling Company, Spokane, Washington, under subcontract to Fenix and Scisson, Inc. The hole was cored for the US Department of Energy and the Rockwell Hanford Operations' Basalt Waste Isolation Program. Fenix and Scisson, Inc. furnished the engineering, daily supervision of the core drilling activities, and geologic core logging for hole DC-6. Core hole DC-6 is located within the boundary of the Hanford Site at the old Hanford town site. The Hanford Site coordinates for DC-6 are North 54,127.17 feet and West 17,721.00 feet. The surface elevation is approximately 402 feet above sea level. The purpose of core hole DC-6 was to core drill vertically through the basalt and interbed units for stratigraphic depth determination and core collection and to provide a borehole for hydrologic testing. The total depth of core hole DC-6 was 4336 feet. Core recovery was 98.4% of the total footage cored.

The MHD and high-temperature fuel cell literature was surveyed for data pertaining to materials properties in order to identify materials used in MHD power generation which also might be suitable for component use in high-temperature fuel cells. Classes of MHD-electrode materials evaluated include carbides, nitrides, silicides, borides, composites, and oxides. Y/sub 2/O/sub 3/-stabilized ZrO/sub 2/ used as a reference point to evaluate materials for use in the solid-oxide fuel cell. Physical and chemical properties such as electrical resistivity, coefficient of thermal expansion, and thermodynamic stability toward oxidation were used to screen candidate materials. A number of the non-oxide ceramic MHD-electrode materials appear promising for use in the solid-electrolyte and molten-carbonate fuel cell as anodes or anode constituents. The MHD-insulator materials appear suitable candidates for electrolyte-support tiles in the molten-carbonate fuel cells. The merits and possible problem areas for these applications are discussed and additional needed areas of research are delineated.

A nodal method for multidimensional light water reactor (LWR) static and transient analysis is presented in this report. This method efficiently solves one- or two-group diffusion equations using an analytic solution procedure. This report details significant improvements made to those aspects of the method previously reported in the literature. Eigenvalues and power distributions are presented for several static benchmark problems. Time-dependent results for a difficult two-dimensional BWR kinetics benchmark problem are presented. A reference solution for this benchmark problem is also presented. The results presented in this report are summarized, and suggestions are made as to appropriate ways to extend this work to multi-group fast breeder reactor analysis.

Techniques for probabilistic response-surface analysis have been developed to obtain the probability distributions of the consequences of postulated nuclear-reactor accidents. The uncertainties of the consequences are caused by the variability of the system and model input parameters used in the accident analysis. Probability distributions are assigned to the input parameters, and parameter values are systematically chosen from these distributions. These input parameters are then used in deterministic consequence analyses performed by mechanistic accident-analysis codes. The results of these deterministic consequence analyses are used to generate the coefficients for analytical functions that approximate the consequences in terms of the selected input parameters. These approximating functions are used to generate the probability distributions of the consequences with random sampling being used to obtain values for the accident parameters from their distributions. A computer code PROSA has been developed for implementing the probabilistic response-surface technique. Special features of the code generate or treat sensitivities, statistical moments of the input and output variables, region-wise response surfaces, correlated input parameters, and conditional distributions. The code can also be used for calculating important distributions of the input parameters. The use of the code is illustrated in conjunction with the fast-running accident-analysis code SACO to provide probability …

The Liu and Jordan method of calculating long term average energy collection of flat plate collectors is simplified (by about a factor of 4), and generalized to all collectors, concentration and non-concentrating. The only meteorological input needed are the long term average daily total hemispherical insolation H/sub h/ on a horizontal surface and, for thermal collectors the average ambient temperature. The collector is characterized by optical efficiency, heat loss (or U-value), heat extraction efficiency, concentration ratio and tracking mode. An average operating temperature is assumed. Interaction with storage can be included by combining the present model with the f-chart method of Beckman, Klein and Duffie. Formulas and examples are presented for five collector types: flat plate, compound parabolic concentrator, concentrator with E.-W. tracking axis, concentrator with polar tracking axis, and concentrator with two axis tracking. The examples show that even for relatively low temperature applications and cloudy climates (50 degrees C in New York in February), concentrating collectors can outperform the flat plate. The method has been validated against hourly weather data (with measurements of hemispherical and beam insolation), and has been found to have an average accuracy better than 3% for the long term average radiation available to solar …

A stack of nuclear emulsions was irradiated by 400 Gev/c protons at FNAL. In this work a search for the short-lived particles has been carried out by a new method that allowed to detect secondary events (including the narrow ones) on short distances from the parent star. By measuring angles, momenta and ionizations of the secondary particles they could identify electrons and distinguish them from hadrons. In search for the decays of charged of particles on n{sub s} {ge} 3 charged relativistic particles or of neutral ones on two or four charged particles the environments of the 1120 stars has been looked through up to 1 mm from the center of parent star inside of cone 0{sub L} {le} 4{sup o}. By this method 21 secondary events of the type O + O + n{sub s} have been selected. After excluding background due to the nuclear and electro-magnetic interactions 9 events remained (from which 4 of the type O + O + 2n, 2 of the type O + O + 3p and 4 of the type O + O + 4n). They consider them as decays of the new short-lived particles. All these 9 events are characterized by jet …
