Geothermal Loan Guaranty Program and its impact on geothermal exploration and development

Description: The study showed that the Geothermal Loan Guaranty Program has had only a negligible effect on geothermal development and the response to the program was far less than expected. The streamlining of environmental regulations and leasing policies, and the granting of intangible drilling cost write-offs and depletion allowances to operators would have had a greater impact on geothermal energy development. The loan guaranty program did not promote the undertaking of any new projects that would not … more

Transition metal-graphite catalysts for production of light hydrocarbons from synthesis gas. Interim report, August 1, 1976-April 30, 1978

Description: The unusual and potentially significant selectivity behaviors exhibited by iron- and, particularly, cobalt-graphite intercalates during CO hydrogenation warrant continued investigation, using a differential/integral flow-type reactor capable of operating at elevated reaction pressure, i.e., 0 to 300 psig. Such a system will enable further characterization of these catalysts to be made in at least three important, but heretofore unexamined, areas: this will permit the rapid acquisition of such i… more

EBR-II Environmental Instrumented Subassembly XX08 : Engineering and Assembly

Description: Subassembly XX08 is a fueled and instrumented subassembly designed primarily for an ongoing program to investigate the thermal-hydraulic core environment within EBR-II under normal and off-normal plant operating conditions. XX08 contains 58-xenon-tagged, EBR-II Mark-II driver-fuel elements. The Mark-II fuel is expected to provide XX08 with an irradiation lifetime three times as great as that attained with its predecessor, XX07, i.e., a 9 versus 2.9% burnup. A burnup of 9 at.% is equivalent to a… more

Postirradiation Examinations of Fuel Pins from the GCFR F-1 Series of Mixed-Oxide Fuel Pins at 5. 5 at. % Burnup

Description: Postirradiation examinations were performed on five fuel pins from the Gas-Cooled Fast-Breeder Reactor F-1 experiment irradiated in EBR-II to a peak burnup of approximately 5.5 at. %. These encapsulated fuel pins were irradiated at peak-power linear ratings from approximately 13 to 15 kW/ft and peak cladding inside diameter temperatures from approximately 625 to 760°C. The maximum diametral change that occurred during irradiation was 0.2% .delta.D/D₀. The maximum fuel-cladding chemical interact… more

Measurement of the total hemispherical emittance of copper and of spectrally selective surfaces. Report No. 2992

Description: The transient calorimetric technique is used to measure the temperature dependence of the total hemispherical emittance of polished copper, solar selective thin films on copper and a solar selective thin film on a metal film on quartz. Experimental results on copper do not agree with the predictions of the Davisson and Weeks theory. A new theory of the emissivity of metals based on the Drude Free Electron model is developed and compared with the expermental data on copper. With no adjustable pa… more

Designing passive solar buildings to reduce temperature swings

Description: Control of temperature swings is a major consideration in design of passive solar heated buildings - especially so as the designer seeks to achieve most of the building heat from the sun. Observations of temperature swings in several passive buildings are cited. Methods of temperature control are discussed, both by means of control intervention such as using of auxiliary backup heating, ventilation, and blowers, and by means of building design. The design approach is preferred as the main cours… more

Hydrology and geochemistry of a Hawaiian geothermal system: HGP-A

Description: A water quality monitoring program of the Hawaii Geothermal Project well A (HGP-A) was conducted for downhole depth samples and continuous discharge samples in 1976 to 1977. The well water was slightly saline (about 5 to 10 percent ocean water) and nearly depleted of magnesium, but contained high concentrations of silica and sulfide. The chemical composition of the well water did not vary much with depth even though the sampling reached the well bottom (approximately 1768 m (5800 feet) below se… more

F1 Phenomenological Test on Fuel Motion : Final Report

Description: TREAT F-series tests are being conducted to provide data on fuel motion in an LMFBR during a hypothetical loss-of-flow accident. Fuel and fuel-boundary conditions in an LMFBR subassembly following sodium voiding and dryout under loss-of-flow conditions are simulated in each F-series test. Simulation is achieved with a single fuel element surrounded by an annular nuclear-heated wall in a dry (no sodium) test capsule. The area inside the heated wall was selected to represent the area inside the p… more

Autoradiography as a Safeguards Inspection Technique for Unirradiated LWR Fuel Assemblies

Description: A nondestructive autoradiographic method is described which can provide a verification that rods in the interior of unirradiated LWR fuel assemblies contain low-enriched uranium. Sufficient absorber must be used to reduce contributions to image density by beta radiation from uranium-238 daughters. When appropriate absorbers are used, the density of the image of a uranium-containing fuel rod is proportional to the uranium-235 enrichment in that rod. Exposure times as short as 1.5 hours can be ac… more

Pennies a day: financing early deployment of photovoltaic utility applications through a user subsidy

Description: Calculations indicate that the benefits of photovoltaic generation are unlikely to be soon realized unless the photovoltaic alternative is supported, as other energy technologies have been, by some sort of economic subsidy. This report describes the results of a preliminary investigation of one way of providing the required subsidy: simply allowing the utility company to recover the additional cost of photovoltaic generation through increases in charges to customers. As is shown, a very substan… more

Impact of the proposed Atikokan electric generating facility on the wet deposition of sulfur in the Boundary Waters Canoe Area

Description: The major impact of the Atikokan Power Plant on the Boundary Waters Canoe Area (BWCA) during precipitation will be related to the increased deposition of acidic sulfate which has been transformed during transit from the SO/sub 2/ source at Atikokan. The BWCA faces an equally serious impact due to the increased washout of SO/sub 2/ which, once in the surface waters, is likely to convert to an acidic sulfate. Both experimental data and theoretical models suggest that the wet deposition of sulfate… more

Determination of bulk diffusion lengths for angle-lapped semiconductor material via the scanning electron microscope: a theoretical analysis

Description: A standard procedure for the determintion of the minority carrier diffusion length by means of a scanning electron microscope (SEM) consists in scanning across an angle-lapped surface of a P--N junction and measuring the resultant short circuit current I/sub sc/ as a function of beam position. A detailed analysis of the I/sub sc/ originating from this configuration is presented. It is found that, for a point source excitation, the I/sub sc/ depends very simply on x, the variable distance betwee… more
