10-MWe solar-thermal central-receiver pilot plant, solar facilities design integration: collector-field optimization report (RADL item 2-25)
Appropriate cost and performance models and computer codes have been developed to carry out the collector field optimization, as well as additional computer codes to define the actual heliostat locations in the optimized field and to compute in detail the performance to be expected of the defined field. The range of capabilities of the available optimization and performance codes is described. The role of the optimization code in the definition of the pilot plant is specified, and a complete description of the optimization process itself is given. The detailed cost model used by the optimizer for the commercial system optimization is presented in the form of equations relating the cost element to each of the factors that determine it. The design basis for the commercial system is presented together with the rationale for its selection. The development of the individual heliostat performance code is presented. Use of the individual heliostat code in a completed study of receiver panel power under sunrise startup conditions is described. The procedure whereby performance and heliostat spacing data from the representative commercial-scale system are converted into coefficients of use in the layout processor is described, and the actual procedure used in the layout processor is …

Accelerator drift-tube braze-joint failures in the PIGMI APF cavity
During the assembly of the Alternating Phase Focusing cavity for the PIGMI Prototype proton accelerator, recurring failures of drift-tube braze joints occurred. In the fabrication technique, a torch braze was used to attach the stems to both the drift-tube body and the stem termination; all materials used were stainless steel. The assemblies were copper plated, using bright-acid-leveling copper plating. Some braze joints, although satisfactorily tension-tested before plating, later failed at a relatively low loading. A detailed investigation of one drift tube indicated that residual copper-plating solution in the cooling passages acted to dissolve the braze solution over a period of weeks, leading to an eventual joint failure.

Accomplishments of the Small-Hydro Outreach Program. Final report
In September 1980, the Small-Hydro Outreach Program was established by the US Department of Energy and the California Department of Water Resources to promote and encourage the development of small hydroelectric power projects as a renewable energy resource in California. Projects at existing hydraulic structures were particularly emphasized since they have less potential for adverse effect on the environment. Before the outreach program was established, the task force had compiled a list of potential hydro facilities at existing hydraulic structures. The efforts of the outreach program were first aimed at informing the owners of the potential and development procedures for their sites. When the small hydro rush snowballed in the Spring of 1981, numerous requests for information on small hydro development on free flowing streams where no diversions or hydraulic structures existed were received. The outreach program was modified at that time to consider small hydro projects at both undeveloped and developed sites. The main accomplishments of the outreach program have been the publication of Small-Scale Hydro News, conducting a Small-Scale Hydro Workshop and the distribution of bulletins, reports, and pamphlets to reach over 3000 persons interested in small hydro development.

Active solar heating and cooling information user study
The results of a series of telephone interviews with groups of users of information on active solar heating and cooling (SHAC). An earlier study identified the information user groups in the solar community and the priority (to accelerate solar energy commercialization) of getting information to each group. In the current study only high-priority groups were examined. Results from 19 SHAC groups respondents are analyzed in this report: DOE-Funded Researchers, Non-DOE-Funded Researchers, Representatives of Manufacturers (4 groups), Distributors, Installers, Architects, Builders, Planners, Engineers (2 groups), Representatives of Utilities, Educators, Cooperative Extension Service County Agents, Building Owners/Managers, and Homeowners (2 groups). The data will be used as input to the determination of information products and services the Solar Energy Research Institute, the Solar Energy Information Data Bank Network, and the entire information outreach community should be preparing and disseminating.

Adsorptive behavior of polycyclic aromatic hydrocarbons in coal-conversion wastewaters. Six months progress report
A coupled column system was designed and assembled for use in solubility and adsorption testing. This system consists of a saturated solution generation column and an adsorption column. The generation column has been employed successfully to determine the solubility behavior of naphthalene; for nine determinations at 25 /sup 0/C the aqueous solubility is 32.9 +- 1.2 milligrams per liter. However, adsorption isotherm data obtained from the coupled column system involved techniques which are limited by time constraints and accuracy. Batch adsorption shake testing using the generation column to prepare solutions offers an acceptable alternative to this sytem. This procedure has been employed to obtain adsorption isotherm data for naphthalene. Thirty-one data points were obtained for equilibrium concentrations from 0.00689 to 18.8 milligrams per liter. These data can be fitted to the Freundlich equation with constant values of 263 for the coefficient and 0.39 for the exponent. Adsorption and adsorption isotherm models which are more appropriate than the Freundlich equation for purposes of detailed modelling are reviewed.

Advanced pulverized-coal combustor for control of NO/sub x/ emissions. Second quarterly report, December 25, 1980-April 3, 1981
Second quarter results under the Advanced Pulverized Coal Combustor for Control of NO/sub x/ Emissions Program are reported. The program uses an idealized one-dimensional combustor, incorporating fuel staging. A comprehensive computer model is being developed under the program to allow NO mechanisms and rates to be extracted from the experimental data. During the quarter, modification of the existing PROF code to include particle effects was begun. Various aspects of the solution procedure are described in this report. Refinements in the kinetic thermochemical data are completed, providing satisfactory agreement between calculated NO predictions and selected experimental data. Combustor mechanical design was described last quarter. The heat transfer analysis used in the design of the combustor is reported herein. Initial combustion tests will be run next quarter.

Advanced thermionic technology program. Progress report No. 47, April, May, June 1981
The primary long-term goal is to improve thermionic performance to the level that thermionic topping of fossil-fuel powerplants becomes technically possible and economically attractive. An intermediate goal is to operate a thermionic module in a power plant during the mid-1980's. A short-term goal is to demonstrate reliable thermionic operation in a combustion environment. Progress made during the three-month period from April through June 1981 is reported. During this period, significant accomplishments include: (1) continuing stable output from the combustion test of the one-inch diameter hemispherical silicon carbide diode (Converter No. 239) at an emitter temperature of 1730 K for a period of over 8500 hours; (2) determination of the elemental composition (i.e., molybdenum, nickel and cesium) through the sublimed molybdenum collector of Converter No. 262; and (3) demonstration of tungsten CVD onto molybdenum flange using a reuseable graphite mandrel.
