Gulf Coast Programmatic Environmental Assessment Geothermal Well Testing: The Frio Formation of Texas and Louisiana

Description: In accordance with the requirements of 10 CFR Part 711, environmental assessments are being prepared for significant activities and individual projects of the Division of Geothermal Energy (DGE) of the Energy Research and Development Administration (ERDA). This environmental assessment of geopressure well testing addresses, on a regional basis, the expected activities, affected environments, and possible impacts in a broad sense. The specific part of the program addressed by this environmental assessment is geothermal well testing by the take-over of one or more unsuccessful oil wells before the drilling rig is removed and completion of drilling into the geopressured zone. Along the Texas and Louisiana Gulf Coast (Plate 1 and Overlay) water at high temperatures and high pressures is trapped within Gulf basin sediments. The water is confined within or below essentially impermeable shale sequences and carries most or all of the overburden pressure. Such zones are referred to as geopressured strata. These fluids and sediments are heated to abnormally high temperatures (up to 260 C) and may provide potential reservoirs for economical production of geothermal energy. The obvious need in resource development is to assess the resource. Ongoing studies to define large-sand-volume reservoirs will ultimately define optimum sites for drilling special large diameter wells to perform large volume flow production tests. In the interim, existing well tests need to be made to help define and assess the resource. The project addressed by this environmental assessment is the performance of a geothermal well test in high potential geothermal areas. Well tests involve four major actions each of which may or may not be required for each of the well tests. The four major actions are: site preparation, drilling a salt-water disposal well, actual flow testing, and abandonment of the well.

Geothermal logging instrumentation development progress report

Description: Evaluation of the first 275 C voltage regulators delivered by Teledyne Philbrick has begun. Teledyne delivered 50 units to Sandia; testing is being performed with the aid of microprocessor based testers and laboratory ovens. Thus far, the units short-term stability and output voltage temperature coefficient are within specification. The 4000 pF capactiros have been successfully fabricated for the Teledyne Philbrick voltage-to-frequency converter hybrid circuit. The capacitors are stable in that they changed less than {+-} 1.5% between room temperature and 300 C. The Sandia exhibit of high temperature components and hybrid circuits was well received at the annual Geothermal Resources Council Meeting in Reno, Nevada, during September 24-26, 1979. A high percentage of attendees requested purchase information for the display items. Such interest indicates a ready market for commercialization. Development of a 300 C integrated circuit, operational amplifier (op amp) is underway at Harris Semiconductor under a Sandia contract. This 300 C op amp will be pin-for-pin replacement for the popular Harris HA4602 quad op amp (rated to 125 C) that is commonly used in many commercial logging tools.

Solid state physics program. Final report

Description: During the 17 year period of this research, experimental and theoretical investigations were completed in many aspects of cohesive properties of metals and alloys and dielectric properties of various crystals and glasses together with the temperature and pressure derivatives of both properties. Studies of the magnetization and magnetic anisotropy indicate superparamagnetism is common in oligatomic condensed films and any decreased magnetic moment must be associated with surface atoms. Large intrinsic stresses are associated with growth morphology and impurities at grain boundaries. Transport properties in normal metals have been investigated theoretically. A number of basic theorems for disordered systems were derived. (204 references) (auth)

PuO/sub 2/ dissolution problem for LWR plutonium recycle and LMFBR fuels: fabrication and reprocessing problems and their resolution

Description: A survey was made of the information reported to date for laboratory-scale dissolution experiments on PuO/sub 2/-UO/sub 2/ fuels, of reprocessing plant problems that might be encountered with these fuels, and of the fabrication methods for producing these fuels. The possibility of producing fuels that will be highly soluble in pure nitric acid without resorting to the use of corrosive fluorides for complete dissolution is examined. The report concludes that production of highly soluble fuel is possible, that it is probably economically justifiable, and that fluorides are not necessary for dissolution. Highly soluble fuel would likely have minimal impact on reprocessing criticality and waste disposal problems. Reactor specifications for PuO/sub 2/-UO/sub 2/ fuels seemingly permit a greater degree of nonhomogeneity than is desirable for achieving high solubility. A fuel solubility criteria is therefore proposed that would limit the amount of insoluble PuO/sub 2/ in irradiated fuels to less than or equal to 0.01 percent of the total amount of plutonium present.

1974 conceptual design description of a bedded salt pilot plant in southeast New Mexico

Description: The policy of the United States Atomic Energy Commission is to take custody of all commercial high-level radioactive wastes and maintain control of them in perpetuity. This policy (Title 10, Code of Federal Regulations, Part 50, Appendix F) requires that the high-level wastes from nuclear fuels reprocessing plants be solidified within five years after reprocessing and then shipped to a federal repository within ten years after reprocessing. Ultimate disposal sites and/or methods have not yet been selected and are not expected to be ready when waste deliveries begin about 1983. Therefore, the AEC plans to build an interim storage facility, called Retrievable Surface Storage Facility (RSSF), to store and isolate the waste from man and his environment until the suitability of the permanent repository is demonstrated and public acceptance has been established. Meantime, the AEC is proceeding with the study and development of an ultimate disposal method. Bedded salt is being considered for ultimate waste disposal, and work is in progress to develop a Bedded Salt Pilot Plant to demonstrate its acceptability. The pilot plant will permit in situ verification of laboratory work on the interaction of heat and radioactivity of the waste with the salt and surroundings. One concept of such a pilot facility is described.

Coal Technology Program progress report for April 1977

Description: Several modifications were made in the bench scale hydrocarbonization system in an attempt to develop a procedure for handling of caking coals. Experimental work on the pyrolysis of large blocks of coal, on pressurized carbonization of residues, and on three-phase mixing was continued. Impact testing of 10-in.-thick pressure vessel steel disclosed major gradients in impact properties. Development of a variety of methods for nondestructive testing of wear- and process-resistant coating was continued. The development of welding techniques for cladding of carbon steels with Alloy 320 stainless steel has been successful. A microprobe examination of high alloy steel tubes that had been exposed in a fluidized bed combustor for 500 hr revealed about 0.001-in.-thick scales of predominantly calcium sulfate. In the gas-fired potassium boiler project design, fabrication, and installation of equipment needed for initial operations with potassium was continued. Similarly, the design study of a coal-fired boiler for an alkali metal vapor topping cycle was continued. Engineering study and technical support work continued with activities in process modeling; a survey of industrial coal conversion equipment capabilities; and studies of processes for heat recovery, rapid hydrogenation, and purification of hot gas. Process and program assistance work included studies on low-Btu gasification, high-Btu gasification, liquefaction, direct combustion, advanced power conversion, and in-situ gasification of coal.

Coal Technology Program progress report, March 1977

Description: In the final hydrocarbonization experiment with Wyodak subbituminous coal, the coal was hydrocarbonized at 1100/sup 0/F and 300 psig in the recirculating fluidized bed. Two-dimensional pyrolysis behavior of an eastern bituminous coal (Pittsburgh seam) continues to be examined. Results to date indicate that swelling is significantly more pronounced at very low heating rates. Several activities in progress are related to inspection techniques for wear- and process-resistant coatings. Experimental investigations of fireside corrosion on tubing from a fluidized bed combustor have proceeded with metallographic examination and analyses of the scale formed during the test exposure. Methods for nondestructively determining remaining tube wall thickness and scale thickness were developed. Failure prevention and analysis work was aimed at several parts from the Solvent Refined Coal Plant in Ft. Lewis, Washington. The mechanical design of the gas-fired potassium boiler system was completed with the issue of the last four drawings. One electrical and five instrument and control drawings were completed and some fabrication work was completed. Surveys of industrial coal conversion capabilities continued with emphasis on rotating components, valves, hot gas cleanup devices, and heat recovery equipment. Process and program analysis research studies continued with work on low-Btu gasification, direct combustion, advanced power conversion, liquefaction, high-Btu gasification, in-situ gasification, and beneficiation. In the fossil energy environmental project, a first draft of a landfill assessment report was issued for review. Work continued on the Environmental Monitoring Handbook and Pipeline Gas Programmatic Assessment.

European waste-to-energy systems: case study of Koersor, Denmark

Description: Koersor, Denmark operates a waste-to-energy system for only 20,000 persons. Energy is recovered in the form of heat for district heating and the facility has been operating reliably for about four years. The apparent success of this installation suggests that the system may have applications in smaller communities. The design and operation of the facility are summarized. The energy recovered from the boiler amounts to about 7,000 kilotherms (kth) per year. The thermal efficiency of the plant is estimated at approximately 50 percent. Taking into account energy which is lost because it cannot be sold, the overall efficiency decreases to approximately 30 percent. The total cost of the complex was 7,000,000 Kr ($944,700; 1971 or $1,437,600; 1976) with 4,600,000 of that sum going for the incinerator. There was no subsidy from the Danish government; the plant was entirely financed with municipal funds. The overall cost of incineration is estimated today at 120 Kr per metric ton ($18 per short ton) including both capital and operating cost, after making provision for the value of heat recovered.
