Nuclear energy can be used to produce hydrogen. The key strategic question is this: ''What are the early markets for nuclear hydrogen?'' The answer determines (1) whether there are incentives to implement nuclear hydrogen technology today or whether the development of such a technology could be delayed by decades until a hydrogen economy has evolved, (2) the industrial partners required to develop such a technology, and (3) the technological requirements for the hydrogen production system (rate of production, steady-state or variable production, hydrogen purity, etc.). Understanding ''early'' markets for any new product is difficult because the customer may not even recognize that the product could exist. This study is an initial examination of how nuclear hydrogen could be used in two interconnected early markets: the production of electricity for peak and intermediate electrical loads and spinning reserve for the electrical grid. The study is intended to provide an initial description that can then be used to consult with potential customers (utilities, the Electric Power Research Institute, etc.) to better determine the potential real-world viability of this early market for nuclear hydrogen and provide the starting point for a more definitive assessment of the concept. If this set of applications is …

This report analyzes how the cost-sharing and premium provisions under Part D would affect the amount that a beneficiary would pay annually for prescription drugs. In addition, this report gives examples of how annual cost-sharing would differ for beneficiaries with various levels of total prescription drug spending in 2006 under the plan's standard benefit.

We have demonstrated 466mW of 469nm light from a frequency doubled continuous wave fiber laser. The system consisted of a 938nm single frequency laser diode master oscillator, which was amplified in two stages to 5 Watts using cladding pumped Nd{sup 3+} fiber amplifiers and then frequency doubled in a single pass through periodically poled KTP. The 3cm long PPKTP crystal was made by Raicol Crystals Ltd. with a period of 5.9 {micro}m and had a phase match temperature of 47 degrees Centigrade. The beam was focused to a 1/e{sup 2} diameter in the crystal of 29 {micro}m. Overall conversion efficiency was 11% and the results agreed well with standard models. Our 938nm fiber amplifier design minimizes amplified spontaneous emission at 1088nm by employing an optimized core to cladding size ratio. This design allows the 3-level transition to operate at high inversion, thus making it competitive with the 1088nm 4-level transition. We have also carefully chosen the fiber coil diameter to help suppress propagation of wavelengths longer than 938 nm. At 2 Watts, the 938nm laser had an M{sup 2} of 1.1 and good polarization (correctable with a quarter and half wave plate to >10:1).

Implantation of 33 keV C{sup +} ions into polycrystalline U{sup 238} with a dose of 4.3 x 10{sup 17} cm{sup -2} produces a physically and chemically modified surface layer that prevents further air oxidation and corrosion. X-ray photoelectron spectroscopy and secondary ion mass spectrometry were used to investigate the surface chemistry and electronic structure of this C{sup +} ion implanted polycrystalline uranium and a non-implanted region of the sample, both regions exposed to air for more than a year. In addition, scanning electron microscopy was used to examine and compare the surface morphology of the two regions. The U 4f, O 1s and C 1s core-level and valence band spectra clearly indicate carbide formation in the modified surface layer. The time-of-flight secondary ion mass spectrometry depth profiling results reveal an oxy-carbide surface layer over an approximately 200 nm thick UC layer with little or no residual oxidation at the carbide layer/U metal transitional interface.

This paper discusses the multi-year ''campaign'' to measure and reduce the transverse impedances of the original DARHT-2 accelerator cells in order to limit the beam-breakup instability (BBU) growth through the machine. A series of three prototype cells were designed, modeled, and measured. One of the most important methods for limiting the impedance was the introduction of ferrite absorbers in the oil region immediately upstream of the insulator. When properly tuned in terms of thickness, the effective Q's could be significantly reduced for both the 10 inch ''standard'' cells and the 14 inch ''injector'' cells. We also present a new experimental method (twin lead-loop) to measure the transverse impedance. This method has a number of important advantages over the well-known TSD approach, especially in the low Q regime. For the final prototype standard cell design, we found that Z-perp could be limited to <300 ohms/m with Q's ranging from 3 to 6. There was reasonable agreement between measurements and simulation results from the AMOS code (peak amplitudes within 25-30 percent) with the exception that the resonant mode around 200 MHz had a double-peaked structure that could not be reproduced by simulation.

Genetic databases are generally created with the long-term goal of establishing genotype-phenotype correlations, and are explicitly NOT intended for participant benefit through the personal receipt of genetic information. In fact, most well-known genetic databases are set up to preclude the recontact of participants, both to protect confidentiality and because any genetic discoveries will likely have unclear implications in the near future. Issues of recontact and sample use raise significant issues around the informed consent process for such genetic databases. The NUgene study is a longitudinal genetic database at Northwestern University created to assess the genetic components of common diseases. In summer 2001, prior to the start of NUgene recruitment, a planning committee met for over one year to discuss the project's format, including ethical aspects. The project's advisory committee felt strongly that recontact of study participants was not warranted. However, because of the broad and longitudinal nature of the project, the IRB requested a modified consent process for recontacting subjects. This consent allowed participants to opt for recontact under either of the following circumstances: (1) if more information was required for a future study or to participate in future research and (2) if ''clinically significant results'' were discovered through research …

The U.S. is the largest producer of mining products in the world. In 2003, U.S. mining operations produced $57 billion worth of raw materials that contributed a total of $564 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies that can be used by the U.S. mining industry to create new products, reduce production costs, and meet environmental regulations. Much of the research to be conducted with Cooperative Agreement funds will be longer-term, high-risk, basic research and will be carried out in five broad areas: (1) Solid-solid separation; (2) Solid-liquid separation; (3) Chemical/Biological Extraction; (4) Modeling and Control; and (5) Environmental Control.
