Data gathered at well water sites in the Edgemont detail area, including applicable water chemistry measurements (e.g., pH, conductivity, alkalinity), physical measurements (e.g., temperature, well description, scintillometer readings), and elemental analyses.

Results of the Edgemont detailed geochemical survey are reported. Field and laboratory data are presented for 109 groundwater and 419 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are given. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed. Groundwaters containing greater than or equal to 7.35 ppB uranium are present in scattered clusters throughout the area sampled. Most of these groundwaters are from wells drilled where the Inyan Kara Group is exposed at the surface. The exceptions are a group of samples in the northwestern part of the area sampled and south of the Dewey Terrace. These groundwaters are also produced from the Inyan Kara Group where it is overlain by the Graneros Group and alluvium. The high uranium groundwaters along and to the south of the terrace are characterized by high molybdenum, uranium/specific conductance, and uranium/sulfate values. Many of the groundwaters sampled along the outcrop of the Inyan Kara Group are near uranium mines. Groundwaters have high amounts of uranium and molybdenum. Samples taken downdip are sulfide waters with low values of uranium …

Results of a reconnaissance geochemical survey of the Corpus Christi Quadrangle, Texas, are reported. Field and laboratory data are presented for 119 groundwater samples and 57 stream sediment samples. Also included is a brief discussion on the geology and hydrology of the quadrangle. Groundwater data indicate that uranium concentrations above the 85th percentile occur primarily in a trend in western Nueces County. With one exception, waters in the trend are produced from the Evangeline aquifer and have high values for selenium and strontium. Owing to urbanization, low topographic relief, and the presence of Recent-to-Pleistocene surface material, stream sediment data were found to be less than optimum for the determination of the potential for uranium mineralization, and variation in uranium concentrations between units may simply reflect lithologic differences.

During FY 1980 work is being carried out on the following subtasks: evaluation of the thermal/hydraulic/mechanical consequences of enhanced fertile and fissile capture rates at interfaces; development of simpler ways to estimate interface capture rate enhancement; particularization of the breed/burn internal/external blanket management scheme; and participation in the Large Core Code Evaluation Working Group (LCCEWG) program.

The proposed continuation project is restricted to underground energy storage and includes: underground pumped hydro storage (UPH); second generation compressed air energy storage (CAES); and seasonal aquifer thermal energy storage (SATES). In the economic assessment component of the proposed study superconducting magnetic energy storage (SMES) will also be included for the purposes of economic comparison only. Within the scope of the proposed effort the following specific objectives have been identified: continuation of extensive analysis of technical and economic information in the form of published and unpublished papers, reports and personal communication, synthesis and critical evaluation of the above information; continuation of the comprehensive analysis of Underground Energy Storage Project activities (updating results obtained in the first year of the project); updating and development of information to provide timely input on the progress to TMS staff for planning purposes; identification of major technical, economic and institutional issues having adverse effect on commercialization and advancement of strategy for resolution; and updating of economic analyses of various storage technologies by the modified method developed during the first years. Progress in each of these efforts is discussed.

The use of carbonaceous adsorbents is limited by irreversible adsorption of some compounds so the use of supercritical pentane as an extracting solvent was examined. Carbon black appeared to be broken down slowly, but continuously, by the penane. To see if other types of carbon behaved similarly, high purity graphite, technical grade graphites, active carbons, and charcoals were examined. The extracts were characterized by uv spectroscopy, packed column chromatography using flame ionization and flame photometric detectors, and capillary GC/MS. The extracts were characteristic for each class of carbonaceous material. The high purity graphite yielded large, polycyclic aromatic compounds; the technical grade graphites yielded alkanes and alkyl-substituted benzenes and naphthalenes; the active carbons yielded alkanes, dienes, and small amounts of alkyl-substituted benzenes; and the charcoals yielded almost entirely alkanes in small amounts.

Disposal of high-level radioactive wastes is a major environmental problem influencing further development of nuclear energy in this country. Salt domes in the Gulf Coast Basin are being investigated as repository sites. A major concern is geologic and hydrologic stability of candidate domes and potential transport of radionuclides by groundwater to the biosphere prior to their degradation to harmless levels of activity. This report conceptualizes a regional geohydrologic model for transport of radionuclides from a salt dome repository. The model considers transport pathways and the physical and chemical changes that would occur through time prior to the radionuclides reaching the biosphere. Necessary, but unknown inputs to the regional model involve entry and movement of fluids through the repository dome and across the dome-country rock interface and the effect on the dome and surrounding strata of heat generated by the radioactive wastes.

A nationwide examination was made of grassroots energy conservation programs related to transportation. Information compiled from civic groups, trade associations, and corporations is included on driver awareness/mass transit; travel; and ride sharing. It is concluded that a willingness by the public to cooperate in transportation energy conservation exists and should be exploited. (LCL)

Task II, Direct Impact on Consumers, contains 3 subtasks: life-cycle cost to the consumer, usage patterns, and long-term demand forecast and analysis. The 2 subtasks in Task III, Energy Savings and Impact on Utilities, are residential energy savings and cost and impact on utility generating capacity.

The pilot plant was configured to accomplish two objectives - first to evaluate the overall performance potential of direct contact powerplants and second to develop design criteria and parameters for full-scale direct contact plants. The pilot plant includes all of the process functions that would be incorporated in a full-scale plant. Incoming brine is treated to remove undissolved gases, pumped through the direct contact heat exchanger (DCHX), and then sent to a recovery system for removal of the dissolved working fluid. The chosen working fluid is isobutane (IC/sub 4/). The working fluid loop includes a radial inflow turbine with generator, condensers, hot-well reservoir, and a feed pump. A downwell pump was installed in the geothermal well to supply the plant with unflashed brine. (MHR)

In analyzing the behavior of a vacuum arc during interruption , a mathematical model has been set up to describe the events occurring in the interelectrode gap during interruption. The reliability of the results obtained using such a model depends on the accuracy of the initial assumptions made in setting up the model equations. Previous results obtained from the model analysis were compared to experimental data and it was found that there was a discrepancy close to current zero. To improve our model results some of the original model assumptions have been reconsidered in order to make the model more closely represent the physical reality of a vacuum arc.

The Raft River Geothermal Site is located in Southern Idaho's Raft River Valley, southwest of Malta, Idaho, in Cassia County. EG and G idaho, Inc., is the DOE's prime contractor for development of the Raft River geothermal field. Contract work has been progressing for several years towards creating a fully integrated utilization of geothermal water. Developmental progress has resulted in the drilling of seven major DOE wells. Four are producing geothermal water from reservoir temperatures measured to approximately 149 C (approximately 300 F). Closed-in well head pressures range from 69 to 102 kPa (100 to 175 psi). Two wells are scheduled for geothermal cold 60 C (140 F) water reinjection. The prime development effort is for a power plant designed to generate electricity using the heat from the geothermal hot water. The plant is designated as the ''5 MW(e) Raft River Research and Development Plant'' project. General site management assigned to EG and G has resulted in planning and development of many parts of the 5 MW program.

The University of Tennessee Space Institute (UTSI) reports on significant activity, task status, planned research, testing, development, and conclusions for the Magnetohydrodynamics (MHD) Coal-Fired Flow Facility (CFFF) and the Research and Development Laboratory. Although slowed by incessant rain during several days, work on the CFFF Bid Packages progressed to nearly 100 percent completion, excluding later punchlist items. On the quench system, the cyclone separator was delivered to UTSI, and under Downstream Components, the secondary combustor was received and the radiant slagging furnace was emplaced at the CFFF. Water quality analysis of Woods Reservoir provided the expected favorable results, quite similar to last year's. Generator experiments describing local current distribution are reported along with behavior under conditions of imposed leakage. Also, during the Quarter, the shelter for the cold flow modeling facility was constructed and circuits installation begun. A jet turbine combustor was tested for use as a vitiation burner. Samples taken from the exhaust duct, besides other applications, show that the refractories used are performing well in alleviating heat loss while exhibiting acceptable degredation. A new resistive power take-off network was designed and implemented.

A pulsed electron accelerator has been constructed and is now in operation at the Lawrence Livermore Laboratory. This Experimental Test Accelerator (ETA) a 5 MeV, 10 kA, 50 ns FWHM, five pulse burst at 1 kHz, was designed to be the front end or injector for the Advanced Test Accelerator (ATA). The ATA is presently under construction and will have the following parameters: beam energy - 50 MeV, beam current - 10 kA, pulse length - 70 ns, repetition rate in a ten pulse burst - 1 kHz. The parameters which make the pulse power components unique for these machines are the high repetition rate in a burst and a high degree of regulation in the system to insure pulse to pulse repeatability. Because of the larger number of components requird for ATA, a much higher degree of reliability will be required. Improvements and modifications continue to be made on the ETA, which is serving as a base of development for all ATA pulse power components. Furthermore, all ATA pulse power components will be tested at length in a test stand before beginning mass production to insure proper design to meet voltage, current, rep-rate and life requirements.

Program TOMSCAT is an interactive code that calculates the scattering spectrum and background for a Thomson-scattering diagnostic in typical magnetic fusion plasmas. Thomson scattering yields values of the plasma electron temperature T/sub e/ and electron density N/sub e/. This program is intended as an aid for designing Thomson-scattering systems, so all experimental parameters are input by the user. The code is operational on OCTOPUS.

The I-SAVE (Iowa Saves America's Vital Energy) conservation plan provides comprehensive energy-conservation information and services to residential consumers served by large investor-owned electric and gas utilities and participating home-heating suppliers. The overall objective of the I-SAVE plan is to conserve energy by facilitating cost-effective retrofit of existing housing and promoting more-efficient energy use. The ultimate benefit available to the customer under the I-SAVE plan - reduction in energy use - is dependent upon the action he or she takes as a result of the program audit. Benefits to the utility and the ratepayers as a whole, however, will accrue only upon widespread customer acceptance and utilization of program services. This degree of program acceptance and the resulting benefits to ratepayers can be attained only through an aggressive educational and promotional effort by the covered utilities. All electric and gas utilities which have sales, other than resale, exceeding 750 million kWh of electricity or 10 billion cubic feet of gas and participating home-heating suppliers, shall provide a program announcement and shall offer conservation services to their customers who occupy a residential building containing at least one, but not more than four units, in a manner as provided by the rules.
