Soil-Structure Interaction Methods, SIM Code. Volume III
The Structure In Media (SIM) Code determines the response of a structure, embedded in soil/rock media, to a specified dynamic disturbance in the media. The structure is modeled as a series of lumped mass, elastic beams which may be interconnected with elastic springs. The disturbance in the free field is specified in terms of an accelerogram, the scale of which may vary with depth. Soil/structure interaction is treated in two parts. The first determines the interaction forces developed at the base of the structure while the second evaluates the interaction forces developed along the side walls of the structure. Details of the model are discussed.

Evaluation of physical characteristics and phenomena, sensitivity and interaction effects, performance criteria and output requirements for a station keeping subsystem engineering evaluation tool (SKEET)
The fundamental purpose for SKEET is to provide a means of simulating and evaluating OTEC platform SKSS performance. This evaluation capability may be employed in the process of a design review, comparison of alternative concepts, operational planning, establishing risk and reliability criteria and a host of other applications. However, the central requirement is that SKEET have the capability to predict the excursions on motions of the platform and loads on the SKSS as a result of environmental effects under a range of operational conditions. The principal elements which should be represented by the SKEET model include: environment (wind, current, waves); vessel/CWP configuration; mooring system (including anchor/soil and electrical riser cable interactions); and dynamic positioning system effects. Findings are summarized of the following two tasks that have been undertaken to formulate a definition of the requirements of SKEET: Task III - identify and classify the physical characteristics and phenomena and evaluate interaction effects; and Task IV - establish mooring performance criteria. The objective of Task III was to define the range of physical parameters that must be incorporated into SKEET and to make an assessment of the most appropriate manner in which to incorporate each of those parameters. The objective of …

Preliminary designs for ocean thermal energy conversion (OTEC) stationkeeping subsystems (SKSS). Task II. Conceptual design. Final report
The study is presented in five sections: design loads, conceptual designs, trade studies, cost analysis and concept evaluation and ranking. Extensive appendixes provide back up calculations and data to support the results. Environmental forces and yaw moments acting on the barge and spar in the various design sea states are presented including wave, wind and current effects. A parametric analysis illustrates the impact on holding power requirement of varying the return periods for operational and extreme sea state. The conceptual designs are presented for the barge followed by those for the spar, including configuration definition, performance characteristics, interfaces, areas for development, and deployment scenarios for selected concepts. The concept definition is followed by a set of trade studies that were performed to evaluate candidate anchor types and anchor leg materials. Parametric variations in anchor leg characteristics, wire-rope-to-chain length ratio for example, illustrate the influence of the significant design parameters on performance. An extensive cost analysis of the candidate SKSS concepts is presented, including cost estimates, life cycle cost scenarios leading to expected value of life cycle cost, and cost equivalence of operational failures. An evaluation of the eight SKSS concepts is presented, including assessment of performance and rankings based on …

Study of hydrogen-powered versus battery-powered automobiles
A study conducted to compare the technological status and the resultant potential vehicle characteristics for hydrogen- and battery-powered automobiles that could be produced from 1985 to 2000 is documented in 3 volumes. The primary objectives of the study were: the assessments of applicable energy storage and propulsion technology for the two basic vehicle types (applied to four-passenger cars); a rigorous comparison of vehicle weight, size, and usefulness versus design range; and an investigation of the relative efficiencies of expending energy from various primary sources to power the subject vehicle. Another important objective, unique to hydrogen powered vehicles, was the assessment of the technology, logistics, and cost implications of a hydrogen production and delivery capability. This volume, Volume III, contains three major sections: the assessment of battery electric vehicle technology for energy storage and the drivetrain system; the technical and economic comparison of hydrogen- and battery-powered vehicles derived primarily from data in the previous vehicle technology assessments, with consideration of alternative energy sources; and a series of appendices that support the vehicle definitions and comparisons.

Comparison of cesium iodide and gold photocathodes for x-ray streak cameras
X-ray streak cameras at Lawrence Livermore Laboratory use gold transmission photocathodes for x-ray detection. Other photocathode materials which might provide improved sensitivity without loss of temporal resolution are of interest. Of particular interest are dielectrics such as cesium iodide. Simultaneous measurements of the sensitivity to 500 eV x-rays of both gold and cesium iodide photocathodes in the LLL Soft X-ray Streak Camera were made. Enhanced sensitivity with the Csl photocathodes is reported and no degradation of temporal resolution for 100 ps x-ray pulses is seen. We have established the optimum thickness for maximum sensitivity of gold photocathodes to be 100 A. The maximum sensitivity of cesium iodide was observed for photocathode thickness of 1100 A.

Abbreviated RD and D program portfolio selection workbook
A workbook for implementing an abbreviated version of the RD and D portfolio selection methodology described in A Resource Allocation Methodology for Establishing RD and D Budgetary Priorities is presented. The purpose of the abbreviated methodology is to allow a fast, first-cut analysis of a set of programs and to provide a means of discovering important issues that deserve more detailed analysis. The use of the abbreviated methodology in the overall process of evaluating RD and D programs is outlined. The effect of the program on a process is represented by the process model. Those process cost and performance characteristics that are important to the market for an energy product are described. The product cost model takes the cost and performance characteristics and the feedstock price and calculates the cost of producing a unit of energy using the technology in question. The market model takes this cost, the demand for the energy product, and the characteristics of alternative sources of the same product, and specifies the market share captured by the new technology. From this point it is relatively straightforward to infer the impacts of the new technology on the energy system. The benefit model evaluates the impacts in a …

Powerplant Productivity Improvement Study: project summary report
Key findings from the Illinois Powerplant Productivity Improvement Study are: (1) the historic performance (equivalent availability) of large generating units in Illinois is below national average performance; (2) cost-effective opportunities to improve performance exist, and utilities pursue many of these; (3) there are no strong regulatory disincentives to the undertaking of productivity improvement projects, but no strong incentives either; (4) current utility practices, procedures, and management philosophy toward improved productivity are being strengthened; (5) areas in which immediate attention is warranted include application of reliability engineering tools to the analysis of powerplant availability and more vigorous pursuit of opportunities for performance improvements; (6) DOE systematic methodology for analysis of productivity improvement projects was demonstrated at three units and found to be useful; (7) the potential for improved productivity was estimated to be of the order of 2% in planned and forced outage rates; (8) if a 5% improvement were to be attained, cumulative (through 1990) constant-dollar benefits would be approximately $500 million; (9) formula regulatory incentive mechanisms are presently in a developmental or experimental phase, but adoption by the State of Illinois does not appear warranted at this time; and (10) the Illinois Commerce Commission can encourage improved productivity by …

Radiosensitivity in plants
The report presents a compilation of available data on the sensitivity of plants to ionizing radiation, and provides basic information on methods of determining such sensitivities, or of estimating radiosensitivities by calcuation of the nuclear factors upon which they depend. The scope of the data presented here is necessarily limited to the most generally useful radiobiological end points and to the most commonly-used types of radiation. Many of the factors which influence radiosensitivity, particularly nuclear factors, will be discussed. Emphasis will be upon whole-plant studies done at Brookhaven National Laboratory by A.H. Sparrow and his associates, since these studies are the source of most of the available radiosensitivity data and of all the sensitivity predictions listed here. Data presented here include summaries of experimentally-determined radiosensitivities at various end points for both herbaceous and woody higher plants, and for a few species of ferns and lower plants. The algae and fungi have not been considered here due to space limitations.

Analysis of costs and benefits for eight powerplant productivity improvement projects. Project 1, Task 3. Final report
In 1976, DOE (FEA) sponsored the development of a systematic methodology for the identification and analysis of candidate projects which a utility might undertake to improve baseload unit reliability. This methodology also enabled the user to estimate a project's effect on the future performance of the unit. A project was sponsored in Illinois to demonstrate the methodology and to encourage increased power plant productivity in the state. A total of 8 improvement projects were conducted and analyzed at Illinois Power Company Wood River 5 and Commonwealth Edison Company Quad Cities 1 and 2 units. A general description of the approach followed in estimating costs and benefits and in presenting the results for the 8 projects is provided. A brief technical description of the projects and their total cost, total benefits, net present value, and benefit-to-cost ratio is given. Detailed cost and benefit summaries for each project are presented followed by a discussion of the results.

Development of resin-bead isotope-dilution mass spectrometric techniques for Tc-99 analysis
An isotope dilution mass spectrometric method was developed for the analysis of Tc-99 after isolating it onto anion exchange resin beads. A single resin bead containing Tc-99 and Tc-97 spike is loaded onto a rhenium V-shaped filament for thermal emission mass spectrometry. The application of this technique requires the use of a mass spectrometer of high abundance sensitivity and pulse counting capability for the necessary ion detection sensitivity. This paper discusses the development of the technique, including the mass spectrometer, choice of filament material, scanning modes, interferences, and present achievable sample sensitivities.

Stop bandwidths of nonlinear beam-beam resonances
A general expression is given for the stop bandwidths, ..delta nu../sub N/, of nonlinear beam-beam resonances, which is expanded in powers of Y(s), the vertical beam orbit, and which is valid under certain assumptions regarding the orbits and charge distributions near the interaction regions. This result is applied to obtain results for the rms ..delta nu../sub N/ due to random vertical orbit errors, and due to random errors in ..beta../sub y/ at the crossing points. Numerical results are given for the ISABELLE storage accelerator.

Short residence time hydropyrolysis of coal. Technical progress report, 1 October 1979-31 December 1979
A fundamental study of the hydropyrolysis of small coal particles at high pressures and short residence times of both solid and gas is underway to elucidate the chemical and physical rate processes governing the yield and product distributions. Our experimental system has been designed to rapidly heat and quench small samples of coal in batch. Heating rates to 10/sup 4/ degree C/s and temperatures to 1000/sup 0/C are feasible, and quench times of the order of 50 ms have been achieved. Throughout the temperature program all volatile products are swept continuously from the coal particles by a stream of flowing gases and coled abruptly at a fixed point downstream of the reactor. The flowing stream will range from pure helium to pure hydrogen at pressures up to 100 atm and temperatures to 1000/sup 0/C. After cooling, products are swept through a set of traps which will fractionate them for subsequent elemental and chromatographic analyses. In addition the small particles can be observed during reaction through a viewing port equipped with a microscope and high-speed movie camera or video recorder. Our objectives are (1) to control the environmental conditions as closely as possible to isolate competing rate processes and (2) to …
