A Mining/Contained Explosion Source Phenomenology Experiment to Improve Nuclear Test Monitoring

Description: We propose an experiment to investigate the similarities and differences in source phenomenology and regional seismic discriminant behavior between normal production mining explosions and fully contained nuclear tests. The experiment would consist of a minimum of two large, nearly co-located explosions, which would be recorded at regional distances: (1) a normal delay fired production mining explosion, and (2) a single chemical explosion contained and buried at underground nuclear test depth.

WASTE HANDLING BUILDING SHIELD WALL ANALYSIS

Description: The scope of this analysis is to estimate the shielding wall, ceiling or equivalent door thicknesses that will be required in the Waste Handling Building to maintain the radiation doses to personnel within acceptable limits. The shielding thickness calculated is the minimum required to meet administrative limits, and not necessarily what will be recommended for the final design. The preliminary evaluations will identify the areas which have the greatest impact on mechanical and facility design … more

Preliminary report on self-healing minefield (frogs) concepts and utility in battle

Description: The purpose of this study is to determine battlefield effectiveness of the self-healing minefield (''Frogs'') concept system compared to basecases of the standard AP/AT (anti-personnel/anti-tank) mixed minefield, the AT (anti-tank) pure minefield, and no minefields. This involves tactical modeling where a basecase with and without mines is compared to the concept system. However, it is first necessary to establish system characteristics and behavior of the Frog mine and minefield in order to do… more

State-by-State Comparison of Selected Electricity Restructuring Provisions

Description: Since 1996, twenty-one states have restructured their electricity markets. While the extent of this restructuring varies by state, four issues have generally been considered by all state legislatures: stranded costs, aggregation, universal service, and public benefits. This report compares the treatment of these issues in the restructuring legislation of the twenty-one states. Using information collected directly from the relevant state laws and the rules promulgated by state public utility com… more

Java based open architecture controller

Description: At Lawrence Livermore National Laboratory (LLNL) the authors have been developing an open architecture machine tool controller. This work has been patterned after the General Motors (GM) led Open Modular Architecture Controller (OMAC) work, where they have been involved since its inception. The OMAC work has centered on creating sets of implementation neutral application programming interfaces (APIs) for machine control software components. In the work at LLNL, they were among the early adopter… more

Optimization of retardance for a complete Stokes polarimeter

Description: The authors present two figures of merit based on singular value decomposition which can be used to assess the noise immunity of a complete Stokes polarimeter. These are used to optimize a polarimeter consisting of a rotatable retarder and fixed polarizer. A retardance of 132{degree} (approximately three eights wave) and retarder orientation angles of {+-}51.7{degree} and {+-}15.1{degree} are found to be optimal when four measurements are used. Use of this retardance affords a factor of 1.5 imp… more

Photochemical arrays formed by spatial compartmentalization of colloidal nanoparticles in a polymer-based hydrogel

Description: The development of practical strategies for the assembly of semiconductor and metal colloid nanoparticles into ordered architectures is an area of considerable current interest, since it offers an opportunity for exploiting the optical and electronic properties of these colloids for device development. Prior research has explored creating such organized nanoparticle assemblies by Langmuir-Blodgett techniques or controlled solvent evaporation on suitable substrates. These approaches suffer from … more

Anisotropies in magnetic field evolution and local Lyapunov exponents

Description: The natural occurrence of small scale structures and the extreme anisotropy in the evolution of a magnetic field embedded in a conducting flow is interpreted in terms of the properties of the local Lyapunov exponents along the various local characteristic (un)stable directions for the Lagrangian flow trajectories. The local Lyapunov exponents and the characteristic directions are functions of Lagrangian coordinates and time, which are completely determined once the flow field is specified. The … more

Advanced Thermal Barrier Coating System Development. Technical progress report

Description: The objectives of the program are to provide an improved TBC system with increased temperature capability and improved reliability relative to current state of the art TBC systems. The development of such a coating system is essential to the ATS engine meeting its objectives. The base program consists of three phases: Phase I: Program Planning - Complete; Phase II: Development - Complete; and Phase III: Selected Specimen - Bench Test. Work was performed in Phase II and III of the program during… more

HIGH PRODUCTIVITY VACUUM BLASTING SYSTEM

Description: The purpose of the project is to increase the productivity and economics of existing vacuum blasting technology. This technology is used to remove radioactive contamination, PCB's and lead-base paint and provides worker and environmental protection by continuously recycling the blast media and the full containment of the dust generated in the process.

MEMBRANE SYSTEM FOR RECOVERY OF VOLATILE ORGANIC COMPOUNDS FROM REMEDIATION OFF-GASES

Description: In situ vacuum extraction, air or steam sparging, and vitrification are widely used methods of remediating soil contaminated with volatile organic compounds (VOCs). All of these processes produce a VOC.-laden air stream from which the VOC must be removed before the air can be discharged or recycled to the generating process. Treatment of these off-gases is often a major portion of the cost of the remediation project. Carbon adsorption and catalytic incineration, the most common methods of treat… more

Grazing incidence neutron diffraction from large scale 2D structures

Description: The distorted wave Born approximation (DWBA) is applied to evaluate the diffraction pattern of neutrons (or X-rays) from a 2D array of dots deposited onto a dissimilar substrate. With the radiation impinging on the surface at a grazing incidence angle {alpha}, the intensities diffracted both in and out the plane of specular reflection are calculated as a function of the periodicity of the array, height and diameter of the dots. The results are presented in the form of diffracted intensity conto… more

Phase formation and superconductivity in PIT-type (Bi,Pb)-1212

Description: It was shown via powder-in-tube (PIT) processing that the (Bi,Pb)-1212 phase readily forms inside a silver sheath at 920 C in air. Composition, oxygen pressure, time, and temperature were all varied to study their effects on (Bi,Pb)-1212 phase purity and superconductivity.

RECOVERY OF MERCURY FROM CONTAMINATED PRIMARY AND SECONDARY WASTES

Description: Effective removal of mercury contamination from water is a complex and difficult problem. In particular, mercury treatment of natural waters is difficult because of the low regulatory standards. For example, the Environmental Protection Agency has established a national ambient water quality standard of 12 parts-per-trillion (ppt), whereas the standard is 1.8 ppt in the Great Lakes Region. In addition, mercury is typically present in several different forms, but sorption processes are rarely ef… more
