Heavy Ion Fusion (HIF) is considered a promising path to a practical fusion reactor. A driver for a HIF reactor will require a large number of quadrupole arrays to focus heavy ion beams. A conceptual design, and trade off studies of the quadrupole array based on racetracks are presented. A comparison with a conventional shell magnet is given and advantages and disadvantages are discussed. A more detailed design of a single quadrupole for the High Current experiment (HCX) is presented and discussed.

This project include experimental data and a set of models for relating elastic moduli/porosity/texture and static-to-dynamic moduli to strength and failure relationships for unconsolidated sands and clayey sands. The results of the project should provide the industry with a basis for wider use of oil base drilling fluids in water sensitive formations by implementing drill cutting injection into existing wells at abandoned formations and controlling fracture geometry to prevent ground water contamination.

The US Department of Energy (DOE)-Electric Power Research Institute (EPRI) Turbine Verification Program (TVP) has played a vital role in improving the understanding of lightning protection for wind turbines. In response to concerns from host utilities, the TVP began a lightning protection project to study the impact of lightning activity at the 6.0-megawatt (MW) wind power facility in Ft. Davis, Texas. McNiff Light Industry (MLI) and Global Energy Concepts (GEC) established a broad observation and documentation effort to survey the lightning protection methodologies used and to evaluate the damage resulting from lightning activity at the turbines. The 6.05-MW wind power plant in Searsburg, Vermont, was inspected after a severe lightning storm caused damage to several turbines there. Zond, McNiff, and consultants from Lightning Technologies, Inc. conducted post-damage inspections at both sites to develop recommendations for improving lightning protection. Site operators implemented the recommended mitigation strategies, and the turbines were monitored to determine if the protection measures improved project operations. This paper summarizes the experience gained through TVP's lightning-related research, and provides a set of guidelines for wind turbine manufacturers, owners, and operators.

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed Medicaid and the State Children's Health Insurance Program's (SCHIP) efforts to make dental care more available to low-income people, focusing on: (1) factors that explain low dental service use by Medicaid and SCHIP beneficiaries; and (2) the role of other federal safety-net programs in improving access to dental care."

Alternative for removing heat from Phase 1, low-activity waste feed double-shell tanks using the ventilation systems have been analyzed for Phase 1 waste feed delivery. The analysis was a parametric study using a model that predicted the waste temperatures for a range of primary and annulus ventilation system flow rates. The analysis was performed to determine the ventilation flow required to prevent the waste temperature from exceeding the Limiting Conditions for Operation limits during normal operation and the Safety Limits during off-normal events.

As part of the US Department of Energy/Electric Power Research Institute (DOE-EPRI) Wind Turbine Verification Program, Global Energy Concepts (GEC) is engaged in planning and conducting power performance tests for wind turbines in Searsburg, Vermont; Glenmore, Wisconsin; Algona, Iowa; Springview, Nebraska; Kotzebue, Alaska; and Big Spring, Texas. The turbines under investigation include a 550-kW Zond Z-40 FS, a 600-kW Tacke 600e, two 750-kW Zond Z-50s, a 66-kW AOC 15/50, a 660-kW Vestas V-47, and a 1.65-MW Vestas V-66. The testing is performed in a variety of terrain types, including mountains, plains, deserts, and coastal tundra; and under a wide range of atmospheric conditions from arid to arctic. Because one goal of this testing program is to gain experience with the new International Electrotechnical Commission (IEC) 61400-12 standard, all of the measurements are being performed in accordance with this new standard. This paper presents the status of the power performance testing at each site, the methodologies employed, test results available, and lessons learned from the application of the IEC standard. Any sources of uncertainty are discussed, and attention is given to the relative importance of each aspect of the IEC standard in terms of its contribution to the overall measurement uncertainty.

Reactive spreading, in which a chemically active element is added to promote wetting of noble metals on nonmetallic materials, is evaluated. Theories for the energetics and kinetics of the necessary steps involved in spreading are outlined and compared to the steps in compound formation that typically accompany reactive wetting. These include: fluid flow, active metal adsorption, including nonequilibrium effects, and triple line ridging. All of these can be faster than compound nucleation under certain conditions. Analysis and assessment of recently reported experiments on metal/ceramic systems lead to a focus on those conditions under which spreading proceeds ahead of the actual formation of a new phase at the interface. This scenario may be more typical than believed, and perhaps the most effective situation leading to enhanced spreading. A rationale for the pervasive variability and hysteresis observed during high temperature wetting also emerges.

We are continuing with the development of fast ({approx} 12 MeV) neutron imaging techniques for use in NDE applications. Our goal is to develop a neutron imaging system capable of detecting sub-mm-scale cracks, cubic-mm-scale voids and other structural defects in heavily-shielded low-Z materials within thick sealed objects. The final system will be relatively compact (suitable for use in a small laboratory) and capable of acquiring both radiographic and full tomographic image sets. The design of a prototype imaging detector will be reviewed and results from several recent imaging experiments will be presented. The concurrent development of an intense, accelerator-driven neutron source suitable for use with the final production imaging system will also be discussed.

Metrology inside a D/T burning fusion reactor must necessarily be conducted remotely since the in-vessel environment would be highly radioactive due to neutron activation of the torus walls. A technique based on frequency modulated coherent laser radar (FM CLR) for such remote metrology is described. Since the FM CLR relies on frequency shift to measure distances, the results are largely insensitive to surface reflectance characteristics. Results of measurements in TFTR and NSTX fusion devices using a prototype FM CLR unit, capable of remotely measuring distances (range) up to 22 m with better than 0.1-mm precision, are provided. These results illustrate that the FM CLR can be used for precision remote metrology as well as viewing. It is also shown that by conducting Doppler corrected range measurements using the CLR, the motion of objects can be tracked. Thus, the FM CLR has the potential to remotely measure the motion of plasma facing components (PFCs) during plasma disruptions.

A new gravity finger model was proposed in this report in the absence of interfacial tension but in the presence of gravities. This model considered differences in density and viscosity of the two fluids. Thus, it was able to represent both stable and unstable displacements, and the finger development along either the upper or the bottom walls of a channel. This solution recovers the Saffman - Taylar solution if gravity is neglected. The results of the solution are very similar to the solutions proposed by Brener et al. for the gravity number up to 10. The solution provided in this work only has one free parameter while the solution of Brener et al. has three.

In this work we are attempting to perform the highly efficient storage of solar energy in the form of H{sub 2} via photocatalytic decomposition of water. While it has been demonstrated that H{sub 2} and O{sub 2} can be evolved from a single vessel containing a single suspended photocatalyst (Sayama 1994; 1997), we are attempting to perform net water-splitting by using two photocatalysts immobilized in separate containers, or beds. A schematic showing how the device would work is shown.

This report studied macro-scale heterogeneity effects. Reflecting on their importance, current simulation practices of flow and displacement in porous media were invariably based on heterogeneous permeability fields. Here, it was focused on a specific aspect of such problems, namely the stability of miscible displacements in stratified porous media, where the displacement is perpendicular to the direction of stratification.

The purpose of this Test and Evaluation Plan (TEP) is to identify the Test and Evaluation (T&E) activities required to confirm that design and installation of systems, structures, and components (SSCs) provided by Project W-521 will satisfy Level 2 and operational requirements, and to describe the T&E program to be implemented during the various project phases. This TEP establishes a sequence of test and evaluation activities to provide confidence that all required T&E activities will be accomplished successfully to support a smooth and timely turnover of completed SSCs to the River Protection Project (RPP) operations organization. In addition, organizational responsibilities for managing and performing the T&E activities are outlined. This TEP was prepared in accordance with the guidance and requirements of the RPP Test and Evaluation Management Plan. The Project W-521 TEP documents the process that will show that the SSCs are (1) compliant with the requirements of the Level 2 Specifications, (2) constructed in accordance with approved design drawings and procurement/construction specifications, (3) installed properly and appropriately integrated into the existing systems, and (4) will operate adequately on turnover to the customer.

This document presents the results and documentation of the non-destructive ultrasonic examination (NDE) of tank 241-AP-107. An NDE contractor was retained to provide and use an ultrasonic inspection system (equipment, procedures, and inspectors) to scan a limited area of the primary tank wall, welds, and lower knuckle of double-shell tank 241-AP-107. The exam found no reportable indications of wall thinning, pits, or crack in excess of the acceptance criteria.

The 10th Workshop provided a forum for an informal exchange of technical and scientific information between international researchers in the photovoltaic and non-photovoltaic fields. Discussions included the various aspects of impurities and defects in silicon-their properties, the dynamics during device processing, and their application for developing low-cost processes for manufacturing high-efficiency silicon solar cells. Sessions and panel discussions also reviewed thin-film crystalline-silicon PV, advanced cell structures, new processes and process characterization techniques, and future manufacturing requirements to meet the ambitious expansion goals described in the recently released US PV Industry Roadmap. The Workshop also provided an excellent opportunity for researchers in private industry and at universities to recognize a mutual need for future collaborative research. The three-day workshop consisted of presentations by invited speakers, followed by discussion sessions. In addition, there was two poster sessions presenting the latest research and development results. The subjects discussed included: solar cell processing, light-induced degradation, gettering and passivation, crystalline silicon growth, thin-film silicon solar cells, and impurities and defects. Two special sessions featured at this workshop: advanced metallization and interconnections, and characterization methods.
