Enhanced convective and film boiling heat transfer by surface gas injection
Heat transfer measurements were made for stable film boiling of water over a horizontal, flat stainless steel plate from the minimum film boiling point temperature, T{sub SURFACE} {approximately}500K, to T{sub SURFACE} {approximately}950K. The pressure at the plate was approximately 1 atmosphere and the temperature of the water pool was maintained at saturation. The data were compared to the Berenson film-boiling model, which was developed for minimum film-boiling-point conditions. The model accurately represented the data near the minimum film-boiling point and at the highest temperatures measured, as long it was corrected for the heat transferred by radiation. On the average, the experimental data lay within {plus minus}7% of the model. Measurements of heat transfer were made without film boiling for nitrogen jetting into an overlying pool of water from nine 1-mm- diameter holes, drilled in the heat transfer plate. The heat flux was maintained constant at approximately 26.4 kW/m{sup 2}. For water-pool heights of less than 6cm the heat transfer coefficient deceased linearly with a decrease in heights. Above 6cm the heat transfer coefficient was unaffected. For the entire range of gas velocities measured (0 to 8.5 cm/s), the magnitude of the magnitude of the heat transfer coefficient only changed by …

Valley filled sand stones In a kootenai formation on the Crow Indian Reservation South Central Montana: Quarterly technical report, January 1, 1997--March 31, 1997
Field investigation of the Kootenai valley-fill sandstones was begun in the first quarter. About one half of the outcrop belt was inventoried for occurrences of channel sandstone before heavy snows came to the area. Five exposures of valley-fill sandstone have been located, of these two are 15 meters (50 feet) or greater in thickness and have excellent porosity and permeability. These will be measured and studied in detail during the next field season (1997). No further field work was possible during the second and third quarters because of snow cover. Subsurface data is being collected, organized, and a digital database is being prepared for the project. Geographix petroleum software will probably be used to manage and manipulate the data. Regional subsurface cross sections are being constructed for correlation purposes. All of the four 30 X 60 geologic quadrangles, the Billings, Bridger, Hardin, and Lodge Grass, have been scanned to produce a digital surface geologic data base for the Crow Reservation. These maps are currently being proofed and edited for accuracy. A four-day oil and gas training seminar for Crow Tribal members was completed and was quite successful. The purpose was to enable tribal members and employees to understand and evaluate …

Nuclear structure models: Applications and development. [Department of Physics, Tennessee Technological University, Cookeville, Tennessee]
This report summarizes the progress made during the period July 1, 1992 to April 30, 1993. The study of rotational structure at moderate spins in odd-odd nuclei (Section 1) has continued into the A [approximately] 80 region. Recent experimental data for the positive parity band in [sup 82]Y, including absolute BM1 and BE2 values, are rather well described with a prolatish'' triaxial shape and a [pi]g[sub 9/2] [direct product] [nu]g[sub 9/2] configuration. Little effect from a protonneutron interaction has been found so far. Current studies of odd mass nuclei (Section 2) are mainly focussing on low spin, low energy states in the A [approximately] 130 region as a probe to the evolving collectivity. These projects involve direct collaboration with experimental colleagues. Finally, a view of the microscopic foundation of particle-core coupling models approached from the equation of motion method is presented (Section 3).

Libby/Hungry Horse Dams Wildlife Mitigation Habitat Protection : Interim Report.
The Columbia River Basin Fish and Wildlife Program identified mitigation goals for Hungry Horse and Libby dams (1987). Specific programs goals included: (1) protect and/or enhance 4565 acres of wetland habitat in the Flathead Valley; (2) protect 2462 acres of prairie habitat within the vicinity of the Tobacco Plains Columbian sharp-tailed grouse; (3) protect 8590 acres riparian habitat in northwest Montana for grizzly and black bears; and (4) protect 11,500 acres of terrestrial furbearer habitat through cooperative agreements with state and federal agencies and private landowners. The purpose of this project is to continue to develop and obtain information necessary to evaluate and implement specific wildlife habitat protection actions in northwestern Montana. This report summarizes project work completed between May 1, 1990, and December 31, 1990. There were three primary project objectives during this time: obtain specific information necessary to develop the mitigation program for Columbian sharp-tailed grouse; continue efforts necessary to develop, refine, and coordinate the mitigation programs for waterfowl/wetlands and grizzly/black bears; determine the opportunity and appropriate strategies for protecting terrestrial furbearer habitat by lease or management agreements on state, federal and private lands. 19 refs., 1 tab.

Wildlife and Wildlife Habitat Mitigation Plan for the Noxon Rapids and Cabinet Gorge Hydroelectric Projects, Final Report.
Mitigation projects for wildlife species impacted by the Noxon Rapids and Cabinet Gorge hydroelectric projects are recommended. First priority projects encompass the development of long-term wildlife management plans for WWP lands adjacent to the two reservoirs. General objectives for all WWP lands include alternatives designed to protect or enhance existing wildlife habitat. It is also suggested that WWP evaluate the current status of beaver and river otter populations occupying the reservoirs and implement indicated management. Second priority projects include the protection/enhancement of wildlife habitat on state owned or privately owned lands. Long-term wildlife management agreements would be developed with Montana School Trust lands and may involve reimbursement of revenues lost to the state. Third priority projects include the enhancement of big game winter ranges located on Kootenai National Forest lands. 1 ref., 1 fig., 7 tabs.

Effects of Water Levels on Productivity of Canada Geese in the Northern Flathead Valley, 1985 Annual Report.
Operation of Hungry Horse Dam on the South Fork Flathead River causes sporadic water level fluctuations along the main stem Flathead River. Changes in chronology of seasonal water level fluctuations and substantial habitat losses have occurred as a result of construction and operation of Kerr Dam, which regulates Flathead Lake. These fluctuations may impact goose populations through flooding and erosion of nesting and brood-rearing habitats, and increased susceptibility of nests and young to predation. The number, location, and success of goose nests were determined through pair surveys and nest searches. Our 1985 pair count data indicated that 95 to 143 nests may have been present. Hatching success for 1985 nests (55%) was low compared to long-term averages for the region. Predation was the predominant cause of ground nest failure (25 nests); we documented 2 nest failures due to flooding. The maximum gosling count in the study area for 1985 was 197. Six key brood-rearing areas were identified. Most (80%) sites were located in the herbaceous or pasture cover type and the riparian bench landform. Analysis of aerial photographs taken prior to construction of Kerr Dam documented the loss of 1859 acres of habitat along the north shore of Flathead Lake. …

Economic Evaluation of CO2 Sequestration Technologies Task 4, Biomass Gasification-Based Processing
Biomass derived energy currently accounts for about 3 quads of total primary energy use in the United States. Of this amount, about 0.8 quads are used for power generation. Several biomass energy production technologies exist today which contribute to this energy mix. Biomass combustion technologies have been the dominant source of biomass energy production, both historically and during the past two decades of expansion of modern biomass energy in the U. S. and Europe. As a research and development activity, biomass gasification has usually been the major emphasis as a method of more efficiently utilizing the energy potential of biomass, particularly wood. Numerous biomass gasification technologies exist today in various stages of development. Some are simple systems, while others employ a high degree of integration for maximum energy utilization. The purpose of this study is to conduct a technical and economic comparison of up to three biomass gasification technologies, including the carbon dioxide emissions reduction potential of each. To accomplish this, a literature search was first conducted to determine which technologies were most promising based on a specific set of criteria. During this reporting period, the technical and economic performances of the selected processes were evaluated using computer models and …

Valley-Fill Sandstone in the Kootenai Formation on the Crow Indian Reservation, South-Central Montana
The subsurface database has been completed for the project. An ACCESS database converted to PC-Arcview is being used to manage and interpret the data. Well data and base map data have been successfully imported into Arcview and customized to meet the needs of this project. Log tops and other data from all of the exploration wells in the area have been incorporated into the data base, except for some wells that have no available logs or other information. All of the four 30 x 60 feet geologic quadrangles have been scanned to produce a digital surface geologic data base for the Crow Reservation and all are nearing completion. Formal technical review prior to publication has been completed for all the quandrangles; Billings, Bridger; Hardin, and Lodge Grass. All four quadrangles are in the Bureau's Publications Department being prepared for submittal to a printer. Field investigations were completed during the third quarter, 1997. With the help of a student field assistant from the Crow Tribe, the entire project area was inventoried for the presence of valley-fill deposits in the Kootenai Formation. Field inventory has resulted in the identification of nine exposures of thick valley-fill deposits. These appear to represent at least …

Annual radiological environmental operating report: Browns Ferry Nuclear Plant, 1992. Operations Services/Technical Programs
This report describes the environmental radiological monitoring program conducted by TVA in the vicinity of Browns Ferry Nuclear Plant (BFN) in 1992. The program includes the collection of samples from the environment and the determination of the concentrations of radioactive materials in the samples. Samples are taken from stations in the general area of the plant and from areas not influenced by plant operations. Station locations are selected after careful consideration of the weather patterns and projected radiation doses to the various areas around the plant. Material sampled includes air, water, milk, foods, vegetation, soil, fish, sediment, and direct radiation levels. Results from stations near the plant are compared with concentrations from control stations and with preoperational measurements to determine potential impacts of plant operations. Small amounts of Co-60 and Cs-134 were found in sediment samples downstream from the plant. This activity in stream sediment would result in no measurable increase over background in the dose to the general public.

Annual radiological environmental monitoring report: Watts Bar Nuclear Plant, 1992. Operations Services/Technical Programs
This report describes the preoperational environmental radiological monitoring program conducted by TVA in the vicinity of the Watts Bar Nuclear Plant (WBN) in 1992. The program includes the collection of samples from the environment and the determination of the concentrations of radioactive materials in the samples. Samples are taken from stations in the general area of the plant and from areas that will not be influenced by plant operations. Material sampled includes air, water, milk, foods, vegetation, soil, fish, sediment, and direct radiation levels. During plant operations, results from stations near the plant will be compared with concentrations from control stations and with preoperational measurements to determine potential impacts to the public. Exposures calculated from environmental samples were contributed by naturally occurring radioactive materials, from materials commonly found in the environment as a result of atmospheric fallout, or from the operation of other nuclear facilities in the area. Since WBN has not operated, there has been no contribution of radioactivity from the plant to the environment.

Water quality investigation of Kingston Fossil Plant dry ash stacking
Changing to a dry ash disposal systems at Kingston Fossil Plant (KFP) raises several water quality issues. The first is that removing the fly ash from the ash pond could alter the characteristics of the ash pond discharge to the river. The second concerns proper disposal of the runoff and possibly leachate from the dry ash stack. The third is that dry ash stacking might change the potential for groundwater contamination at the KFP. This report addresses each of these issues. The effects on the ash pond and its discharge are described first. The report is intended to provide reference material to TVA staff in preparation of environmental review documents for new ash disposal areas at Kingston. Although the investigation was directed toward analysis of dry stacking, considerations for other disposal options are also discussed. This report was reviewed in draft form under the title Assessment of Kingston Fossil Plant Dry Ash Stacking on the Ash Pond and Groundwater Quality.'' 11 refs., 3 figs., 18 tabs.

Single molecule detection using charge-coupled device array technology. Final report
An ultra sensitive technique for the detection of fluorescent species in a flowing stream has been developed. The extension of this technique to the detection of fluorescently tagged nucleotides will be a significant benefit to one of the novel approaches for DNA sequencing being developed at Los Alamos National Laboratories. The detection scheme is based on a novel mode of operating a Charge-Coupled Device (CCD) which greatly enhances the discrimination between fluorescence from the analyte and the background Raman scattering from the solvent. Register shifts between rows in the CCD are synchronized with the sample flow velocity so that fluorescence from a single species is collected in a single moving charge packet occupying an area approaching that of a single pixel while the background is spread evenly among a large number of pixels. This research has demonstrated that this technique is highly effective for the detection of fluorescently labelled latex microspheres. With additional development, the authors believe that this technique will achieve single molecule detection.

Air Quality Analysis and Related Risk Assessment for the Bonneville Power Administration's Resource Program Environmental Impact Statement
The Bonneville Power Administration (BPA) is considering 12 different alternatives for acquiring energy resources over the next 20 years. Each of the alternatives utilizes a full range of energy resources (e.g., coal, cogeneration, conservation, and nuclear); however, individual alternatives place greater emphases on different types of power-producing resources and employ different timetables for implementing these resources. The environmental impacts that would result from the implementation of each alternative and the economic valuations of these impacts, will be an important consideration in the alternative selection process. In this report we discuss the methods used to estimate environmental impacts from the resource alternatives. We focus on pollutant emissions rates, ground-level air concentrations of basic criteria pollutants, the acidity of rain, particulate deposition, ozone concentrations, visibility attenuation, global warming, human health effects, agricultural and forest impacts, and wildlife impacts. For this study, pollutant emission rates are computed by processing BPA data on power production and associated pollutant emissions. The assessment of human health effects from ozone indicated little variation between the resource alternatives. Impacts on plants, crops, and wildlife populations from power plant emissions are projected to be minimal for all resource alternatives.
