Ocean energy systems. Quarterly report, October-December 1982

Research progress is reported on developing Ocean Thermal Energy Conversion (OTEC) systems that will provide synthetic fuels (e.g., methanol), energy-intensive products such as ammonia (for fertilizers and chemicals), and aluminum. The work also includes assessment and design concepts for hybrid plants, such as geothermal-OTEC (GEOTEC) plants. Another effort that began in the spring of 1982 is a technical advisory role to DOE with respect to their management of the conceptual design activity of the two industry teams that are designing offshore OTEC pilot plants that could deliver power to Oahu, Hawaii. In addition, a program is underway in which tests of a different kind of ocean-energy device, a turbine that is air-driven as a result of wave action in a chamber, are being planned. This Quarterly Report summarizes the work on the various tasks as of 31 December 1982.

Fact sheets relating to use of geothermal energy in the United States (open access)

Fact sheets relating to use of geothermal energy in the United States

A compilation of data relating to geothermal energy in each of the 50 states is presented. The data are summarized on one page for each state. All summary data sheets use a common format. Following the summary data sheet there are additional data on the geology of each state pertaining to possible hydrothermal/geothermal resources. Also there is a list of some of the reports available pertaining to the state and state energy contacts. The intent of these documents is to present in a concise form reference data for planning by the Department of Energy.

Energy Programs at the Johns Hopkins University Applied Physics Laboratory. Quarterly report, October-December 1979 (open access)

Energy Programs at the Johns Hopkins University Applied Physics Laboratory. Quarterly report, October-December 1979

The Johns Hopkins University Applied Physics Laboratory, under contracts with several agencies of the federal government and an agency of the State of Maryland, is engaged in developing energy resources, utilization concepts, and storage methods. This Quarterly Report summarizes the work on the various tasks as of 31 December 1979. The Energy Quarterly Report is divided into five sections. The first, Geothermal Energy Development Planning and Technical Assistance, supported by the Department of Energy/Resource Applications (DOE/RA), contains reports on the progress of those geothermal-related tasks where effort was concentrated during the quarter. The second section, Operational Research, Hydroelectric Power Development, also supported by DOE/RA, contains reports on small-scale hydroelectric investigations in the southeastern states. The third section, Seismotectonic Studies, supported by the Reactor Safety Research Division of the Nuclear Regulatory Commission, reports on neotectonic investigations in Connecticut. The fourth section, Energy Conversion and Storage Techniques, contains two articles, the first on OTEC core unit testing supported by the Department of Energy, Division of Central Solar Technology (DOE/CST), and the second on recovery of landfill methane, supported by the Argonne National Laboratory. The fifth section, New Energy Technologies, reports on Laboratory studies of an unconventional gas source--Eastern Devonian shales.

Numerical and Physical Modelling of Bubbly Flow Phenomena - Final Report to the Department of Energy (open access)

Numerical and Physical Modelling of Bubbly Flow Phenomena - Final Report to the Department of Energy

This report describes the main features of the results obtained in the course of this project. A new approach to the systematic development of closure relations for the averaged equations of disperse multiphase flow is outlined. The focus of the project is on spatially non-uniform systems and several aspects in which such systems differ from uniform ones are described. Then, the procedure used in deriving the closure relations is given and some explicit results shown. The report also contains a list of publications supported by this grant and a list of the persons involved in the work.

Spectroscopic diagnostics of high temperature plasmas, January 1, 1991--December 31, 1991 (open access)

Spectroscopic diagnostics of high temperature plasmas, January 1, 1991--December 31, 1991

During 1991, the activities of the John Hopkins University Plasma Spectroscopy Group have covered several areas of research, in the domain of XUV spectroscopy of magnetically confined fusion plasmas. While the main effort concentrated on the development of novel diagnostics which utilize Layered Synthetic Microstructures (LSMs) as the dispersive/filtering elements, work has been done in the area of detector development and the physics of the tokamak edge plasma. An XUV monochromator for the 20--200{Angstrom} range, which uses flat LSMs, has been built and is currently operated on the D3-D tokamak at General Atomics in San Diego. A design for a follow-up experiment at D3-D is now in progress. As a preliminary step toward tokamak plasma imaging in the XUV wavelength range using curved LSM coated substrates, a prototype XUV camera was built and operated in our laboratory in image the A1 3 emission at {lambda}-175{Angstrom} from a Penning Ionization Discharge plasma. Based on these laboratory results, the design of the XUV camera, which will image plasma in the Phaedrus T tokamak O VI emission (150{Angstrom}), has been completed. This instrument is presently under construction. Also a detailed design of a system composed of four LSM based imaging devices for N{sub …

Radioactive Waste Disposal Practices in the Atomic Energy Industry. A Survey of the Costs (open access)

Radioactive Waste Disposal Practices in the Atomic Energy Industry. A Survey of the Costs

A survey was made on methcds and related costs of disposing of radioactive wastes as practiced in 1955 by twelve atomic industry installations. Wherever possible, estimated unit costs of differentiated stages of waste handling are shown- these are integrated to show the over-all scope of waste dispesal practices at each site. Tabular data summarize costs and operation magnitades at the installations. A pattern is established for standardizing the reporting of fixed costs and equipment unsage costs. The economy of solid waste volume reduction is analyzed. Material costs are listed. An outline for recording monthly waste disposal costs is presented. Obvious conclusions drawn from the factual data are: that it is more expensive per cubic foot to handle high-level wastes than low-level wastes. and that land disposal is less expenaive than sea disposal. A reexamination of baling economics shows that high compression of solid wastes is more expensive than simpler forms of compaction. (auth)

Geothermal Energy Development in the Eastern United States, Sensitivity analysis-cost of geothermal energy (open access)

Geothermal Energy Development in the Eastern United States, Sensitivity analysis-cost of geothermal energy

The Geothermal Resources Interactive Temporal Simulation (GRITS) model is a computer code designed to estimate the costs of geothermal energy systems. The interactive program allows the user to vary resource, demand, and financial parameters to observe their effects on delivered costs of direct-use geothermal energy. Due to the large number and interdependent nature of the variables that influence these costs, the variables can be handled practically only through computer modeling. This report documents a sensitivity analysis of the cost of direct-use geothermal energy where each major element is varied to measure the responsiveness of cost to changes in that element. It is hoped that this analysis will assist those persons interested in geothermal energy to understand the most significant cost element as well as those individuals interested in using the GRITS program in the future.
