Advanced turbine design for coal-fueled engines. Quarterly technical report, [July 1, 1989--September 30, 1989]
Coal-fueled gas turbines require the development of a number of new technologies which are being identified by METC and its Heat Engines Contractors. Three significant problems, that were Identified early in the development of coal-fueled engines, are the rapid wear of the turbine airfoils due to particulate erosion, the accumulation of deposits on portions of the airfoil surfaces due to slag deposition and the rapid corrosion of airfoils after the breakdown of surface coatings. The technology development study contained in this program is focused on improving the durability of the turbine through the development of erosion and deposition resistant airfoils and turbine operating conditions. The baseline turbine meanline design vas modified to prevent a local shock on the suction side of the rotor airfoil. New particle dimensionless parameters to be varied were determined. Three first-stage turbine meanline designs have been completed. The design of nev turbine airfoil shapes has been initiated. The calculation of particle trajectories has been completed for the baseline turbine vane and blade airfoils. The erosion model described in the previous technical report vas incorporated in the Post Processing Trajectory Analysis Code.

Advanced water-cooled phosphoric acid fuel cell development. Quarterly technical progress report No. 20, October, November, December, 1989
Fabrication of repeat parts for small area short stack is underway: 100 electrode substrates and 150 ERP substrates were graphitized, and 30 electrode substrates were run through each manufacturing step. Teflon content and compaction pressure of shop-made electrodes for the small area short stack was optimized based on single cell tests. A single cell with GSB-18P catalyst and 1 mg/cm{sup 2} loading is performing very well; performance is 0.66 V per cell after 1200 h at 300 ASF. 3 integral separator plate configurations have been selected for verification in the upcoming short stack. Bubble pressures over 7 psid have been demonstrated in filler bands applied with a production curtain and coating process. 5 full-size (small area) coolers were molded, and encapsulation development for molded and commercial graphite coolers continued.

Alkali/TX{sub 2} catalysts for CO/H{sub 2} conversion to C{sub 1}-C{sub 4} alcohols. Technical progress report, March 1989--August 1989
Ruthenium disulfide catalysts have been synthesized, tested, and characterized during this period of research. It was observed that both the undoped and Cs-doped RuS{sub 2} catalysts produced alcohols and lower amounts of hydrocarbons from H{sub 2}/CO = 1.0 synthesis gas at temperatures above 300{degree}C. Calcination and catalytic testing resulted in partial reduction of the RuS{sub 2} to Ru{sup o}. Calcination under H{sub 2}S prevented the partial reduction of the RuS{sub 2} catalyst, but subsequent catalytic testing again resulted in the formation of a quantity of Ru{sup o}. A Cs-doped RuS{sub 2} catalyst was prepared, but it might have had too high of a loading of Cs. Upon testing, a lower activity was observed for the doped catalyst compared with the undoped catalyst, but the alcohol selectivity was the same for the two catalysts.

ALT-II progress report and proposal, December 1989--December 1990
The Advanced Limiter Test (ALT-11) is a joint international program among the United States, the Federal Republic of Germany, and Japan to investigate the performance of a toroidal belt pump limiter in a tokamak, to investigate the behavior of the plasma edge, and to relate edge behavior to overall core energy and particle confinement. The experiments are carried out in the TEXTOR tokamak at KFA Juelich, Federal Republic of Germany. The ALT-II experiment was installed in TEXTOR in 1987 with the objectives of optimizing plasma performance in a limiter tokamak, and of studying the physics of particle removal, density and impurity control, and confinement enhancement by a toroidal belt pump limiter. The ALT-II program addresses large area limiter tokamak operation issues by providing a program specifically directed toward plasma optimization and particle and impurity control by a toroidal belt limiter in a machine dedicated to the investigation of plasma-wall interactions. TEXTOR features the most advanced set of edge plasma diagnostics of any tokamak for the task of diagnosing and understanding the impact of the limiter on the plasma confinement and performance. With the addition of 3.4 MW of neutral beam injection heating (NBI) to the existing 4 MW of ion …

Analysis of general circulation model results and comparison with regional climatic data, Task 3. [Progress report]
On time scales of greater than one year the variability of weather and climate on a large path of the Earth is dominated by the Southern Oscillation. While current theories of this phenomenon have clarified the role of the interaction between the ocean and the atmosphere in maintaining this oscillation it has so far been unclear whether the Southern Oscillation originates in the ocean, in the atmosphere or during the interaction between the ocean and the atmosphere. In this study we compared simulations of climate in two global circulation models: the coupled OSU GCM in which the atmosphere and ocean interact dynamically and the slab OSU GCM in which the ocean is represented by a static layer.

Arctic hydrology and meteorology. Annual report
To date, five years of hydrologic and meteorologic data have been collected at Imnavait Creek near Toolik Lake, Alaska. This is the most complete set of field data of this type collected in the Arctic of North America. These data have been used in process-oriented research to increase our understanding of atmosphere/hydrosphere/biosphere/lithosphere interactions. Basically, we are monitoring heat and mass transfer between various spheres to quantify rates. These could be rates of mass movement such as hillslope flow or rates of heat transfer for active layer thawing or combined heat and mass processes such as evapotranspiration. We have utilized a conceptual model to predict hydrologic processes. To test the success of this model, we are comparing our predicted rates of runoff and snowmelt to measured valves. We have also used a surface energy model to simulate active layer temperatures. The final step in this modeling effort to date was to predict what impact climatic warming would have on active layer thicknesses and how this will influence the hydrology of our research watershed by examining several streambeds.

Aromatics oxidation and soot formation in flames. Progress report for year beginning 15 August 1988
Work during this contract period has been concerned with the mechanisms through which aromatics are formed and destroyed in flames, and the processes responsible for soot formation. Recent progress has been primarily in two areas: experiments and modeling of the soot nucleation process in low pressure benzene flames and preparation for experiments on the destruction mechanisms of benzene. In addition, we have incorporated ``weak collision`` formalisms into a fall-off computer code.

Atmospheric deposition, resuspension and root uptake of plutonium in corn and other grain-producing agroecosystems near a nuclear fuel facility
Plutonium released to the environment may contribute to dose to humans through inhalation or ingestion of contaminated foodstuffs. Plutonium contamination of agricultural plants may result from interception and retention of atmospheric deposition, resuspension of Pu-bearing soil particles to plant surfaces, and root uptake and translocation to grain. Plutonium on vegetation surfaces may be transferred to grain surfaces during mechanical harvesting. Data obtained from corn grown near the US Department of Energy`s H-Area nuclear fuel chemical separations facility on the Savannah River Site was used to estimated parameters of a simple model of Pu transport in agroecosystems. The parameter estimates for corn were compared to those previously obtained for wheat and soybeans. Despite some differences in parameter estimates among crops, the relative importances of atmospheric deposition, resuspension and root uptake were similar among crops. For even small deposition rates, the relative importances of processes for Pu contamination of corn grain should be: transfer of atmospheric deposition from vegetation surfaces to grain surfaces during combining > resuspension of soil to grain surfaces > root uptake. Approximately 3.9 {times} 10{sup {minus}5} of a year`s atmospheric deposition is transferred to grain. Approximately 6.2 {times} 10{sup {minus}9} of the Pu inventory in the soil is …

Biological Production of Ethanol From Coal. [Fourth Quarterly Report], October 22, 1989--December 1989
Two batch and one continuous reactor study involving Clostridium ljungdahlii were carried out. First, the effects of H{sub 2} partial pressure on growth, CO and H{sub 2} uptake and product formation by C. ljungdahlii were investigated in batch culture. Over the concentration range studied, it was observed that CO was preferentially utilized in favor of H{sub 2}. It was also seen that increasing H{sub 2} partial pressures increased the ratio of ethanol to acetate. Finally, a two-stage CSTR system was successfully operated with C. ljungdahlii in which growth occurred in the first stage and ethanol production occurred in the second stage.

Calorimetry Sample Exchange analysis of data report for October--December, 1988
The goals of the Calorimetry Sample Exchange Program are to: discuss measurement differences; review and improve analytical measurements and methods; discuss new measurement capabilities; provide data to DOE on measurement capabilities to evaluate shipper-receiver differences; provide characterized or standard materials as necessary for exchange participants; and provide a measurement control program for plutonium analysis. A sample of PuO{sub 2} powder is available at each participating site for NDA measurement, including either or both calorimetry and high-resolution gamma-ray spectroscopy, the elements which are typically combined to provide a calorimetric assay of plutonium. The facilities measure the sample as frequently and to the level of precision which they desire, and then submit the data to the Exchange for analysis. Statistical tests are used to evaluate the data and to determine if there are significant differences from accepted values for the exchange sample or from data previously reported by that facility. This information is presented, in the form of a quarterly report, intended for use by Exchange participants in measurement control programs, or to indicate when bias corrections may be appropriate. No attempt, however, has been made to standardize methods or frequency of data collection, calibration, or operating procedures. Direct comparisons between laboratories …

Carbon and nitrogen isotope studies in an arctic aquatic ecosystem
The Phase II studies of the R4D Program on stream and watershed ecology reflect the accomplishments and accumulation of baseline information obtained during the past studies. Although our rough estimates indicate that nitrogen inputs to the watershed ba lance losses, the carbon fluxes suggest that they are not in equilibrium and that there is a net loss of carbon from the tundra ecosystem through respiration and transport out of the watershed via the stream system. Radiocarbon profiles of soil sections coupled with mass transport calculations revealed that peat accumulation has essentially ceased in the R4D watershed and appears to be in ablative loss. Thus the carbon flux measurements provide validation tests for the PLANTGRO and GAS-HYDRO models of the PHASE II studies. These findings are also important in the context of global CO{sub 2} increases from positive feedback mechanisms in peatlands associated with climatic warming in the subarctic regions.

Carbon and nitrogen isotope studies in an arctic ecosystem
This proposal requests funding for the completion of our current ecological studies at the MS-117 research site at Toolik Lake, Alaska. We have been using a mix of stable and radioisotope techniques to assess the fluxes of carbon and nitrogen within the ecosystem and the implications for long-term carbon storage or loss from the tundra. Several tentative conclusions have emerged from our study including: Tundra in the foothills is no longer accumulating carbon. Surficial radiocarbon abundances show little or no accumulation since 1000--2500 yrs BP. Coastal plain tundra is still accumulating carbon, but the rate of accumulation has dropped in the last few thousand years. Carbon export from watersheds in the Kuparuk and Imnavait Creek drainages are in excess of that expected from estimated primary productivity; and Nitrogen isotope abundances vary between species of plants and along hydrologic gradients.

Chemistry and Materials Science Department annual report, 1988--1989
This is the first annual report of the Chemistry & Materials Science (C&MS) Department. The principal purpose of this report is to provide a concise summary of our scientific and technical accomplishments for fiscal years 1988 and 1989. The report is also tended to become part of the archival record of the Department`s activities. We plan to publish future editions annually. The activities of the Department can be divided into three broad categories. First, C&MS staff are assigned by the matrix system to work directly in a program. These programmatic assignments typically involve short deadlines and critical time schedules. A second category is longer-term research and development in technologies important to Laboratory programs. The focus and direction of this technology-base work are generally determined by programmatic needs. Finally, the Department manages its own research program, mostly long-range in outlook and basic in orientation. These three categories are not mutually exclusive but form a continuum of technical activities. Representative examples of all three are included in this report. The principal subject matter of this report has been divided into six sections: Innovations in Analysis and Characterization, Advanced Materials, Metallurgical Science and Technology, Surfaces and Interfaces, Energetic Materials and Chemical Synthesis, and …

[Collection of low copy number repeats for use as probes in human DNA Mapping]. Progress report, September 15, 1989
To isolate novel families of repeated human sequences our basic plan is to (i) construct repeated sequence libraries, (ii) discard known repeats by hybridization and (iii) sort through the remaining clones to eliminate single copy sequences as well as known repeats that slipped through the first screening. During the previous grant period, we completed the library construction and initial screening. Six size selected sublibraries of renatured human DNA were constructed, e.g. sublibrary II contains 250 nt to 380 nt inserts. The released inserts were hybridized to Alu, L1, THE 1, {alpha} satellite and satellite M (which crosshybridizes to satellites I and H) hybridization probes. We have adopted two strategies to sort through these candidate clones.
