A 100 MVA generator utilizing high temperature superconducting windings -- design assessment & component development. Final report
The operation of a high temperature superconducting generator rotor using closed-cycle refrigeration to indirectly cool the field windings was considered to be the best choice for an HTS application. The SPI program proposed to achieve the following goals: In Task 1 a 100 MVA generator with a HTS rotor field winding would be designed. An energy and economic benefits analysis was to be a key part of the program. In addition, the generator/grid interactions were to be modeled. Concurrently, Task 2 was to include further development of Bi-2223 silver-clad tape as well as an alternate Tl-1223 conductor, manufacture of 3,000 meters of tape, and development and fabrication of a prototype field coil. Details of progress have been reported in the quarterly status reports and summarized in the final reports on the tasks. Therefore this report will give a review of the original goals of each task and summary of results for each.

137Cs(90Sr) and Pu isotopes in the Pacific Ocean sources & trends
The main source of artificial radioactivity in the world`s oceans can be attributed to worldwide fallout from atmospheric nuclear weapons testing. Measurements of selected artificial radionuclides in the Pacific Ocean were first conducted in the 1960`s where it was observed that fallout radioactivity had penetrated the deep ocean. Extensive studies carried out during the 1973-74 GEOSECS provided the first comprehensive data on the lateral and vertical distributions of {sup 9O}Sr, {sup 137}Cs and Pu isotopes in the Pacific on a basin wide scale. Estimates of radionuclide inventories in excess of amounts predicted to be delivered by global fallout alone were attributed to close-in fallout and tropospheric inputs from early U.S. tests conducted on Bikini and Enewetak Atolls in the Equatorial Pacific. In general, levels of fallout radionuclides (including {sup 9O}Sr, {sup 137}Cs and Pu isotopes) in the surface waters of the Pacific Ocean have decreased considerably over the past 4 decades and are now much more homogeneously distributed. Resuspension and the subsequent deposition of fallout radionuclides from previously deposited debris on land has become an important source term for the surface ocean. This can be clearly seen in measurements of fallout radionuclides in mineral aerosols over the Korean Peninsula (Yellow …

Active vibration control of civil structures
This is a final report of a one year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Active vibration control (AVC) of structural and mechanical systems is one of the rapidly advancing areas of engineering research. The multifaceted nature of AVC covers many disciplines, such as sensors and instrumentation, numerical modeling, experimental mechanics, and advanced power systems. This work encompassed a review of the literature on active control of structures focusing both on active control hardware and on control algorithms, a design of an isolation systems using magneto-rheological fluid-filled (MRF) dampers and numerical simulations to study the enhanced vibration mitigation effects of this technology.

An advanced control system for fine coal flotation. Final technical progress report, October 1, 1995--June 30, 1996
A model-based flotation control scheme is being implemented to achieve optimal performance in the handling and treatment of fine coal. The control scheme monitors flotation performance through on-line analysis of ash content. Then, based on the economic and metallurgical performance of the circuit, variables such as reagent dosage, air addition rate, pulp density and pulp level are adjusted using model-based control algorithms to compensate for feed variations and other process disturbances. Recent developments in video-based sensor technology are being applied for on-line determination of slurry ash content. During the third quarter of this project, work continued on the testing and calibration of the video-based ash analyzer, and a plant sampling campaign was conducted to provide data for the development of a mathematical process model and the model-based control algorithms.

Advanced direct liquefaction concepts for PETC generic units: Phase 2. Quarterly technical progress report, July--September, 1996
The Advanced Direct Liquefaction Concepts Program sponsored by the DOE Pittsburgh Energy Technology Center was initiated in 1991 with the objective of promoting the development of new and emerging technology that has the potential for reducing the cost of producing liquid fuels by direct coal liquefaction. The laboratory research program (Phase I) was completed in 1995 by UK/CAER, CONSOL, Sandia National Laboratories and LDP Associates. A three year extension was subsequently awarded in October 1995 to further develop several promising concepts derived from the laboratory program. During Phase II, four continuous bench scale runs will be conducted at Hydrocarbon Technologies, Inc. using a 2 kg/hr continuous bench scale unit located at their facility in Lawrenceville, NJ. The first run in this program (ALC-1), conducted between April 19 and May 14, 1996, consisted of five test conditions to evaluate the affect of coal cleaning and recycle solvent modification. A detailed discussion of this run is included in Section Two of this report. Results obtained during this reporting period for all participants in this program are summarized.

Advanced laser remote sensing
This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory. Remote measurement of wind velocities is critical to a wide variety of applications such as environmental studies, weather prediction, aircraft safety, the accuracy of projectiles, bombs, parachute drops, prediction of the dispersal of chemical and biological warfare agents, and the debris from nuclear explosions. Major programs to develop remote sensors for these applications currently exist in the DoD and NASA. At present, however, there are no real-time, three-dimensional wind measurement techniques that are practical for many of these applications and we report on two new promising techniques. The first new technique uses an elastic backscatter lidar to track aerosol patterns in the atmosphere and to calculate three dimensional wind velocities from changes in the positions of the aerosol patterns. This was first done by Professor Ed Eloranta of the University of Wisconsin using post processing techniques and we are adapting Professor Eloranta`s algorithms to a real-time data processor and installing it in an existing elastic backscatter lidar system at Los Alamos (the XM94 helicopter lidar), which has a compatible data processing and control system. The second novel wind sensing technique …

Advanced materials for aerospace and biomedical applications: New glasses for hermetic titanium seals
Titanium and titanium alloys have an outstanding strength-to-weight ratio and corrosion resistance and so are materials of choice for a variety of aerospace and biomedical applications. Such applications are limited by the lack of a viable hermetic glass sealing technology. Conventional silicate sealing glasses are readily reduced by titanium to form interfacial silicides that are incompatible with a robust glass/metal seal. Borate-based glasses undergo a similar thermochemistry and are reduced to a titanium boride. The kinetics of this reactions, however, are apparently slower and so a deleterious interface does not form. Chemically durable lanthanoborate glasses were examined as candidate sealing compositions. The compositions, properties, and structures of several alkaline earth, alumina, and titania lanthanoborate glass forming systems were evaluated and this information was used as the basis for a designed experiment to optimize compositions for Ti-sealing. A number of viable compositions were identified and sealing procedures established. Finally, glass formation, properties, and structure of biocompatible Fe{sub 2}O{sub 3}- and TiO{sub 2}-doped calcium phosphate systems were also evaluated.

Advanced reservoir characterization and evaluation of CO{sub 2} gravity drainage in the naturally fractured Spraberry reservoir. Quarterly technical report, April 1, 1996--June 30, 1996
Progress has been made in the area of laboratory analysis of Spraberry oil/brine/rock interactions during this quarter. Water imbibition experiments were conducted under ambient conditions, using cleaned Spraberry cores, synthetic Spraberry reservoir brine, and Spraberry oil. It has been concluded that the Spraberry reservoir cores are weakly water-wet. The average Amott wettability index to water is about 0.55. The average oil recovery due to spontaneous water imbibition is about 50% of original oil in place.

Advanced reservoir management for independent oil and gas producers
There are more than fifty-two hundred oil and gas producers operating in the United States today. Many of these companies have instituted improved oil recovery programs in some form, but very few have had access to state-of-the-art modeling technologies routinely used by major producers to manage these projects. Since independent operators are playing an increasingly important role in the production of hydrocarbons in the United States, it is important to promote state-of-the-art management practices, including the planning and monitoring of improved oil recovery projects, within this community. This is one of the goals of the Strategic Technologies Council, a special interest group of independent oil and gas producers. Reservoir management technologies have the potential to increase oil recovery while simultaneously reducing production costs. These technologies were pioneered by major producers and are routinely used by them. Independent producers confront two problems adopting this approach: the high cost of acquiring these technologies and the high cost of using them even if they were available. Effective use of reservoir management tools requires, in general, the services of a professional (geoscientist or engineer) who is already familiar with the details of setting up, running, and interpreting computer models.

Advanced turbine systems program conceptual design and product development Task 8.3 - autothermal fuel reformer (ATR). Topical report
Autothermal fuel reforming (ATR) consists of reacting a hydrocarbon fuel such as natural gas or diesel with steam to produce a hydrogen-rich {open_quotes}reformed{close_quotes} fuel. This work has been designed to investigate the fuel reformation and the product gas combustion under gas turbine conditions. The hydrogen-rich gas has a high flammability with a wide range of combustion stability. Being lighter and more reactive than methane, the hydrogen-rich gas mixes readily with air and can be burned at low fuel/air ratios producing inherently low emissions. The reformed fuel also has a low ignition temperature which makes low temperature catalytic combustion possible. ATR can be designed for use with a variety of alternative fuels including heavy crudes, biomass and coal-derived fuels. When the steam required for fuel reforming is raised by using energy from the gas turbine exhaust, cycle efficiency is improved because of the steam and fuel chemically recuperating. Reformation of natural gas or diesel fuels to a homogeneous hydrogen-rich fuel has been demonstrated. Performance tests on screening various reforming catalysts and operating conditions were conducted on a batch-tube reactor. Producing over 70 percent of hydrogen (on a dry basis) in the product stream was obtained using natural gas as a feedstock. …

Advice and recommendations to the US Department of Energy in response to the charge letter of September 20, 1996
In Jan. 1996, the Fusion Energy Advisory Committee (FEAC) provided recommendations to DOE on how to restructure the fusion program in light of compressional guidance and budget realities. DOE endorsed these recommendations and prepared a strategic plan. The FEAC report concluded that the goals of the restructured program could most effectively be accomplished at a funding level of $275 million per year, including Federal government management costs. DOE requested that Congress appropriate $255.6 million in FY97 for the fusion energy sciences program exclusive of Federal government management costs (about $8 million). On Sept. 11, 1996, the Energy and Water Development Conference Committee settled on a FY97 appropriation for the fusion energy sciences program of $232.5 million. This report contains the response to the charge letter, on how the program described in the strategic plan could be changed to make it consistent with the $232.5 million appropriation.
