Detailed conceptual design of a high temperature glass pH electrode for geothermal applications. Final report, Task I

Description: A modification of the planar electrode technology yielded prototype glass pH electrodes that can withstand the minimum test conditions of 250/sup 0/C and 5000 psi in an aqueous synthetic geothermal brine. Electrodes of this design can be made in volume at reasonable cost.

Design, build, develop and test a fieldworthy spiral tool and packer for casing repair. Final report, March 15, 1992--March 3, 1993

Description: A new method for sealing casing is under research and development by Nu-Bore Systems. The method involves internally lining a section of the wellbore with a multi-layer spiral wrapping of a high strength, corrosion resistant metal interleaved with a high bond strength, resilient epoxy. The high strength metal is preferably a copper based alloy hardened to a very high strength in order to resist the internal and external pressures of downhole environments. The epoxy adhesive formulation is one t… more

Sealing of boreholes using natural, compatible materials: Granular salt

Description: Granular salt can be used to construct high performance permanent seals in boreholes which penetrate rock salt formations. These seals are described as seal systems comprised of the host rock, the seal material, and the seal rock interface. The performance of these seal systems is defined by the complex interactions between these seal system components through time. The interactions are largely driven by the creep of the host formation applying boundary stress on the seal forcing host rock perm… more

SIR FREEZE SEAL TEST II

Description: Two arrangements of internal components of a freeze seal model were tested in order to determine the hydraulic characteristics. The internal configuration employing cylindrical knitted mesh packings in the connecting pipes proved the most suitable for the Na servicing freeze seal, because these packings are more easily fabricated.

Responses of Conventional Ring Closures of Drum Type Packages to Regulatory Drop Tests with Application to the 9974/9975 Package

Description: DOT, DOE and NRC Type A and Type B radioactive material (RAM) transport packages routinely use industrial or military specification drums with conventional clamp ring closures as an overpack. Considerable testing has been performed on these type packages over the past 30 years. Observations from test data have resulted in various design changes and recommendations to the standard drum specification and use, enhancing the reliability of the overpack. Recently, performance capability of the 9975 … more

Initial field testing definition of subsurface sealing and backfilling tests in unsaturated tuff; Yucca Mountain Site Characterization Project

Description: This report contains an initial definition of the field tests proposed for the Yucca Mountain Project repository sealing program. The tests are intended to resolve various performance and emplacement concerns. Examples of concerns to be addressed include achieving selected hydrologic and structural requirements for seals, removing portions of the shaft liner, excavating keyways, emplacing cementitious and earthen seals, reducing the impact of fines on the hydraulic conductivity of fractures, ef… more

Materials aspects of solar energy use in buildings

Description: Advances in materials for solar energy utilization have the potential to produce large performance improvements (both present and future concepts) in use of solar energy or conservation. Because approximately 26 quads of the total national energy budget of 75 quads is consumed by buildings, solar and conservation improvements can have a large effect on our overall energy consumption. There have been a large number of materials research programs funded through the Department of Energy (DOE) in a… more

Impedance measurements on sealed lead--acid cells. [2. 5 Ah, 10 Hz to 500 kHz]

Description: The impedance of sealed 2.5-ampere-hour lead--acid cells was measured as a function of state of charge at frequencies of 10 Hz to 500 kHz. The impedance of a small lead--acid wet cell employing flat-plate electrodes was also measured over this frequency range. Comparisons between the results for these two cell types indicate that impedances are sensitive to chemical and physical changes which accompany cell discharge. A model is proposed which relates inductive behavior for porous electrodes to… more

Vacuum window glazings for energy-efficient buildings

Description: The technical feasibility of a patented, laser-welded, evacuated insulating window was studied. The window has two edge-sealed sheets of glass separated by 0.5-mm glass spheres spaced 30 mm apart in a regular array. A highly insulating frame is required and several designs were analyzed. The vacuum window's combination of high solar transmittance and low thermal conductance makes it superior to many other windows in cold climates. In the US Pacific Northwest, the vacuum window could save a… more

THERMAL CYCLING AND LEAKAGE TESTS OF 12-INCH VALVES FOR SODIUM SERVICE

Description: Tests were performed to determine the effect of thermal cycling on the across-the-seat leakage characteristics of valves for use in the sodium coolant system of the Hallam Nuclear Power Facility. Four 12-in. valves were cycled between 680 and 1100 deg F in a sodium loop and periodically tested for across - the-seat sodium leakage. The valves tested were two throttling (ball) valves and two blocking (gate) valves. The first-ball valve had a consistent leakage pattern which vas primarily a functi… more

Description: Calculations are presented to show the effect of uraniumbearing scale deposits on the HRE-2 core wall tempera ture, heat flux, and the temperature. of patches proposed for sealing the holes of the HRE-2 core vessel. Flow behavior in the HRE-2 core mockup with simulated patches installed and simulated corrosion pits drilled in the vessel wall was determined. A plausible mechanism was advanced to account for hot spots due to sedimentation of solids on metal surfaces projecting from the core wall.… more
