1-GWh diurnal load-leveling Superconducting Magnetic Energy Storage system reference design (open access)

1-GWh diurnal load-leveling Superconducting Magnetic Energy Storage system reference design

A point reference design has been completed for a 1-GWh Superconducting Magnetic Energy Storage system. The system is for electric utility diurnal load-leveling but can also function to meet much faster power demands including dynamic stabilization. This study explores several concepts of design not previously considered in the same detail as treated here. Because the study is for a point design, optimization in all respects is not complete. This report examines aspects of the coil, the superconductor supported off of the dewar shell, the dewar shell, and its configuration and stresses, the underground excavation and construction for holding the superconducting coil and its dewar, the helium refrigeration system, the electrical converter system, the vacuum system, the guard coil, and the costs. This report is divided into two major portions. The first is a general treatment of the work and the second is seven detailed technical appendices issued as separate reports. The information presented on the aluminum stabilizer for the conductor, on the excavation, and on the converter is based upon industrial studies contracted for this work.

1-GWh diurnal load-leveling superconducting magnetic energy storage system reference design. Appendix B: cost study, high-purity aluminum production (open access)

1-GWh diurnal load-leveling superconducting magnetic energy storage system reference design. Appendix B: cost study, high-purity aluminum production

Cost information is supplied for aluminum with purities of 200, 2000, and 5000 residual resistivity ratio. Two production situations were used for each purity: (1) 1 x 10/sup 6/ kg/yr production rate with a 30-yr sustaining market and (2) 1 x 10/sup 6/ kg/yr production rate for 2 yrs only. These productions and purities are of interest for manufacturing devices for Superconducting Magnetic Energy Storage. The cost study results are presented as a range and include (1) the selling price of the aluminum for each case, (2) the cost of facilities including construction, engineering, and related costs, (3) the cost of money and depreciation (interest/amortization), and (4) the energy costs - the total of power and fuel. The range is affected by possible production variations and other uncertainties. Information is also given on plant location options and the preferred feed to the purification facility (with ore source effects).

1-GWh diurnal load-leveling superconducting magnetic energy storage system reference design. Appendix D: superconductive magnetic energy storage cavern construction methods and costs

The excavation and preparation of an underground cavern to contain a 1-GWh diurnal load-leveling Superconducting Magnetic Energy Storage (SMES) unit is examined. The cavern's principal function is to provide a rock structure for supporting the magnetic forces from the charged storage coil. Certain economic considerations indicate the refrigerator cold box for the helium system should also be underground. The study includes such a provision and considers, among other things, rock bolting, water seepage, concrete lining of the walls, steel bearing pads, a system to prevent freezing of the walls, a mining schedule, and costs.

S-1 project. Volume I. Architecture. 1979 annual report

The US Navy is one of the world's largest users of digital computing equipment having a procurement cost of at least $50,000, and is the single largest such computer customer in the Department of Defense. Its projected acquisition plan for embedded computer systems during the first half of the 80s contemplates the installation of over 10,000 such systems at an estimated cost of several billions of dollars. This expenditure, though large, is dwarfed by the 85 billion dollars which DOD is projected to spend during the next half-decade on computer software, the near-majority of which will be spent by the Navy; the life-cycle costs of the 700,000+ lines of software for a single large Navy weapons systems application (e.g., AEGIS) have been conservatively estimated at most of a billion dollars. The S-1 Project is dedicated to realizing potentially large improvements in the efficiency with which such very large sums may be spent, so that greater military effectiveness may be secured earlier, and with smaller expenditures. The fundamental objectives of the S-1 Project's work are first to enable the Navy to be able to quickly, reliably and inexpensively evaluate at any time what is available from the state-of-the-art in digital processing …

50 kWp Photovoltaic Concentrator Application Experiment, Phase I. Final report, 1 June 1978-28 February 1979 (open access)

50 kWp Photovoltaic Concentrator Application Experiment, Phase I. Final report, 1 June 1978-28 February 1979

This program consists of a design study and component development for an experimental 50-kWp photovoltaic concentrator system to supply power to the San Ramon substation of the Pacific Gas and Electric Company. The photovoltaic system is optimized to produce peaking power to relieve the air conditioning load on the PG and E system during summer afternoons; and would therefore displace oil-fired power generation capacity. No electrical storage is required. The experiment would use GaAs concentrator cells with point-focus fresnel lenses operating at 400X, in independent tracking arrays of 440 cells each, generating 3.8 kWp. Fourteen arrays, each 9 feet by 33 feet, are connected electrically in series to generate the 50 kWp. The high conversion efficiency possible with GaAs concentrator cells results in a projected annual average system efficiency (AC electric power output to sunlight input) of better than 15%. The capability of GaAs cells for high temperature operation made possible the design of a total energy option, whereby thermal power from selected arrays could be used to heat and cool the control center for the installation. System design and analysis, fabrication and installation, environmental assessment, and cost projections are described in detail. (WHK)

400 MWe commercial OTEC plants: review of reports by Gibbs and Cox, Inc. , Lockheed Missile and Space Corporation, M. Rosenblatt and Sons

The Department of Energy contracted with Gibbs and Cox, M. Rosenblatt and Son and Lockheed Missile and Space Corporation to prepare conceptual designs, cost estimates and analyses for a 400 MWe OTEC Commercial Size platform. Each contractor was directed to investigate two predetermined hull configurations and to relate them to one operating site, selected by DOE. A total of 6 designs, covering sphere, spar, ship and semisubmersibles were studied by the three contractors. The results of their investigations were presented by DOE in Washington on May 8, 1978. The presentations showed that whereas a considerable data base has been built, no clear conclusions had emerged with respect to the direction that future design of the commercial platform should take. JJMA has been directed by Value Engineering on behalf of DOE to review the conceptual designs and the accompanying data base prepared by the three contractors. The intent of this review is to propose to DOE the answers to the following questions, based on the results of studies by the three contractors: (1) If DOE were to build a 400 MW OTEC plant, starting now, what should they build. (2) What are the reasons for the decisions. (3) What would it …

500-MeV electron beam bench-mark experiments and calculations (open access)

500-MeV electron beam bench-mark experiments and calculations

Experiments measuring the energy deposited by electron beams were performed to provide bench marks against which to evaluate our HANDYL76 electron beam computer code. The experiments, done at Stanford's Mk III accelerator, measured dose vs depth and dose vs radius profiles induced in layered aluminum targets by 500-MeV electrons. The dose was measured by passive thermoluminescence and photographic film placed between aluminum plates. The calculations predict a dose vs radius profile that forward-peaks on axis after the beam passes through a 200-cm air gap; the experimental measurements do not show this peak. This discrepancy indicates there may be a problem in using HANDYL76 to calculate deep penetration of a target with a large gap.

1978 herbaceous production study (open access)

1978 herbaceous production study

Herbaceous productivity studies on the Geokinetics Oil Shale Project Research site in Uintah County, Utah were begun during the summer of 1978. These studies were designed to assess the amount of biomass produced by herbaceous vegetation in each of the vegetation types occurring on the site. Measurements were made in each of the control and treatment plots established for these types. The results given in this report are those obtained from the analysis of data collected during 1978. The chief objective of the herbaceous productivity study is to determine the amount of herbaceous biomass that is potentially available for use by herbivores on the LOFRECO site. As such, these studies are an intergral part of determining the carrying capacity of the site. The data collected from the 1978 study will be used together with other ecological information to provide a functional description of the site. Of particular importance in this synthesis are the data obtained from shrub utilization studies, phytosociological data, and the quantitative descriptions of the physical environment derived from ecoclimatic measurements. Herbaceous productivity will be monitored during the pre and post disturbance phases of the research site development.

1979 breeding bird censuses and summary of 1977-1979 results

As part of a program to characterize the plant and animal life of the Laboratory site and the surrounding region, the two breeding bird censuses originated in 1977 were continued in 1979. Twelve census trips were made to the BNL plot and 10 to the Westhampton plot by seven volunteer observers. Comparisons of data from the three years showed that the number of territorial males on the BNL plot did not change significantly, but the number of breeding species showed a continuous decline, from 18 to 10. Little change in the number of territorial males or in species composition occurred in the Westhampton plot.
