Shawnee test program: TVA Shawnee Test Facility. Technical progress report, April 6-May 6, 1981

Description: The test obtective for April was to evaluate sodium thiosulfate in limestone scrubber slurry as inhibitor of sulfite oxidation. The resulting effect on saturation levels of calcium sulfate (CaSO/sub 4/.2 H/sub 2/O; gypsum) and scaling in the system was of prime importance. As an antioxidant, S/sub 2/O/sub 3//sup =/ functions as a scale inhibitor by reducing SO/sub 4//sup =/, a known scale former. To meet the test objective, the scrubber was operated in a scaling mode as a base case; finally, th… more

Cultural noise in EM prospecting for geothermal resources. Final report

Description: Numerical analysis tools are used to characterize the fields reradiated by cultural scatterers like powerlines, pipelines and fences. These fields are then compared to the returns expected from deeply buried targets and suggestions are made for methods to identify and remove cultural noise from survey data.

Strategies for steam handling and H/sub 2/S abatement at geothermal power plants in The Geysers area of northern California

Description: Strict limitations on the emission of H/sub 2/S from new geothermal power plants in The Geysers area of northern California have been imposed by Lake and Northern Sonoma County Air Pollution Control Districts. Lake County, under new source review rules, has stipulated that specific technologies shall be utilized to limit H/sub 2/S emissions to 5 lb/h as a condition for determination of compliance. The status of these technologies as well as other ongoing technology development efforts to conser… more

Silicon-on-ceramic process: silicon sheet growth and device development for the large-area silicon sheet task of the Low-Cost Solar Array Project. Annual report No. 5, September 29, 1979-September 30, 1980

Description: The objective of this research is to investigate the technical feasibility of producing solar-cell-quality sheet silicon to meet the DOE 1986 cost goal of 70 cents/watt. The silicon-on-ceramic approach is to coat a low-cost ceramic substrate with large-grain polycrystalline silicon by unidirectional solidification of molten silicon. Results are reported. A new silicon-coating system, SCIM-II, was designed and constructed. A design strategy to avoid buckling and breaking of substrates has been f… more

Studies of autoionizing states relevant to dielectronic recombination. Progress report for the third year

Description: An important loss process in CTR plasmas is the process of dielectronic recombination, which proceeds via autoionizing states. At this date, however, this problem is not fully understood, largely because of the nearly complete lack of fundamental atomic data on high excited autoionizing states. In this document, we outline the continuation of a program to investigate the properties of autoionizing states of alkaline earth metals by means of a novel laser excitation technique developed at SRI.

Ambipolar potential formation in TMX

Description: TMX experimental data on ambipolar potential control and on the accompanying electrostatic confinement are reported. New results on the radial dependence of the central-cell confining potential are given. Radial and axial particle losses as well as scaling of the central-cell axial confinement are discussed.

Technical evaluation of the adequacy of station electric distribution system voltages for the R. E. Ginna Nuclear Power Station, Unit 1: selected issues program (Docket No. 50-244)

Description: This report documents the technical evaluation of the adequacy of the station electric distribution system voltages for the R.E. Ginna Nuclear Power Station, Unit 1. The evaluation is to determine if the onsite distribution system, in conjunction with the offsite power sources, has sufficient capacity to automatically start and operate all Class 1E loads within the equipment voltage ratings under certain conditions established by the Nuclear Regulatory Commission. The analysis submitted demonst… more

Parcperdue Geopressure--Geothermal Project: Appendix B

Description: The reservoir models used to perform the drawdown and buildup pressure analyses consist of analytic forms in lieu of the finite difference or numeric simulator types. Analytic models are derived from solutions of the diffusion equation which relate a pressure response with time and distance in the reservoir for a specified flow system. Solutions of the diffusion equation are obtained through mathematical methods such as Laplace transforms, Fourier transforms, Neuman's product techniques and Gre… more

Parcperdue Geopressure -- Geothermal Project: Appendix E

Description: The mechanical and transport properties and characteristics of rock samples obtained from DOW-DOE L.R. SWEEZY NO. 1 TEST WELL at the Parcperdue Geopressure/Geothermal Site have been investigated in the laboratory. Elastic moduli, compressibility, uniaxial compaction coefficient, strength, creep parameters, permeability, acoustic velocities (all at reservoir conditions) and changes in these quantities induced by simulated reservoir production have been obtained from tests on several sandstone an… more

Parcperdue Geopressure -- Geothermal Project: Appendices (C--M)

Description: Twelve flow tests were made on the L. R. Sweezy No. 1 well. Short-term tests, Flow Test No.1 through Flow Test No.4 were designed to estimate formation properties and were conducted for drawdown periods measured in hours. Intermediate-term tests, Flow Test No.5 through Flow Test No.8, were for a few days and were designed to test for reservoir boundaries. Long-term tests, Flow Test No.9 through Flow Test No.12, were designed for drawdown periods of about 60 days in order to examine the depletio… more

Identification of geopressured occurrences outside of the Gulf Coast

Description: The work focused on the occurrences of geopressures in Appalachia and selected California basins. In the former region, where geopressures have been observed, the pressure gradients for the most part were only slightly above normal as in the case of the Oriskany formation of Devonian age; this unit was also characterized by extremely high salinity. The one notable exception was in the Rome trough of West Virginia where Cambrian beds at depths below 10,000 feet display very high geopressures, ap… more
