An experiment has been proposed to investigate a photopumped x-ray laser approach using a novel, high-density, laser heated supersonic gas jet plasma to prepare the lasant plasma. The scheme uses the He- like sodium 1.10027 nm line to pump the He-like neon 1s-4p transition at 1.10003 nm with the lasing transitions between the n=4 to n=2,3 states and the n=3 to n=2 state at 5.8 nm, 23.0 nm, and 8.2 nm, respectively. The experiment had been proposed in 1990 and funding began Jan. 1991; however circumstances made it impossible to pursue the research over the past 5 years, and it was decided not to pursue the research any further.

An experiment had been proposed to investigate a photopumped x-ray laser approach using a novel, high-density, laser heated supersonic gas jet plasma to prepare the lasant plasma. The scheme to be investigated uses the he-like sodium 1.10027 nm line to pump the He-like neon 1s-4p transition at 1.10003 nm with the lasing transitions between the n = 4 to n = 2,3 states and the n = 3 to n = 2 state at 5.8 nm, 23.0 nm, and 8.2 nm, respectively. The experiment had been proposed in 1990 and funding began in January 1991. After extensive preparations to perform the experiment on the GDL laser, a series of circumstances made it impossible to pursue the research over the past 5 years. These were (1) lack of access to the GDL laser and its eventual closing, (2) the inability to identify an alternate laser system with which to perform the experiment, and (3) the lack of problem relevancy after 5 years of delays. As a consequence, it has been decided not to pursue the research any further.

The objectives for this quarter of study on the co-firing of high sulfur coal with refuse derived fuels project were two-fold. First, the organic compounds tentatively identified as combustion products in the previous report were confirmed by comparing retention times with pure samples. Secondly, a reduced amount of unburned carbon in the fly ash and an oxygen concentration at about 3--6% in the flue gases were achieved by the addition of removable heat exchange tubes in the AFBC system.

TPX is PMP or poly(4-methyl-1-pentene). It has several commercially important characteristics such as high optical transparency, high crystalline melting point, etc., leading to numerous applications including infrared windows, lenses, membranes, food packaging. The life components fabricated from this material may be limited by thermal oxidative and radiation-induced degradation. A preliminary review of the scientific literature was conducted to obtain relevant information on the effects of oxygen, moisture elevated temperature, and radiation on the chemical, thermodynamic, mechanical, and electrical properties of this material.

Advances in ICF experiments and modeling have led to improved understanding of the growth of instabilities during capsule implosion and the effects on capsule performance. This has led to more refined specifications on the characteristics of igniting capsules, all of which have solid D-T fuel layers. These specifications involve a trade-off between the interior ice surface structure, outer capsule surface structure, and time-dependent drive asymmetry.

The objective of this research was to develop and implement a shape identification measure within a geographic information system, specifically one that incorporates analytical modeling for site location planning. The application that was developed incorporated a location model within a raster-based GIS, which helped address critical performance issues for the decision support system. Binary matrices, which approximate the object`s geometrical form, are passed over the grided data structure and allow identification of irregular and regularly shaped objects. Lastly, the issue of shape rotation is addressed and is resolved by constructing unique matrices corresponding to the object`s orientation

We are abandoning study of porous polyolefins as regenerator cell separators for now since only radiation grafting seems a suitable technique to make them permanently hydrophilic, and the experts who could do this work need more financial incentive than our application generates. A vendor with a new, moderate cost porous ceramic which can be used for our separators was found though. We designed and built a demonstration scale oxygen ingress compensator cell and are adding it to our pre-prototype regeneration system; actual operation awaits completion of tests on the required proton-selective T&G Corp. membrane. Prototype flow demands require pressurized cell operation and modifications being made to the pre-prototype plating cell will allow testing of design concepts to handle that. Efforts towards an alumina product are discussed.

This report describes experimental studies performed at Carnegie Mellon University to study the parameters that affect the performance of plasma-assisted ammonia radical injection for NO{sub x} control from stationary combustion sources. First, the NO{sub x} reduction potential of hot ammonia injection was studied to determine whether the use of the plasma for radical generation was key to the high NO{sub x} reduction potential of the plasma deNO{sub x} process. It was found that while some of the NO{sub x} reduction in the plasma deNO{sub x} demonstration experiments could be attributed to the enhanced thermal breakdown of NH{sub 3} into NO{sub x} reducing radicals, the effect of using the plasma accounted for 15--35% absolute additional NO{sub x} reduction beyond any thermal benefit. This benefit of using the plasma increases with increased excess air and decreased flue gas temperature. With the benefit of using the plasma verified on the larger scale of a demonstration experiment, two additional experiments were performed to study the parameters that affect plasma deNO{sub x} performance on the local level. The opposed flow experiment failed to produce significant NO{sub x} reduction, although it did highlight some key aspects of plasma performance with ammonia injection. The reverse injection experiment …

We describe a technique to form and smooth uniform solid D{sub 2}, HD or DT layers for inertial confinement fusion targets. Pumping the infrared (IR) collision induced vibration-rotation band generates a bulk heating of the solid. Shadowgraphs reveal that this bulk heat quickly redistributes the solid into a relatively uniform layer depending on the IR intensity profile. Measured redistribution time constants are used to determine the conversion efficiency of IR light into bulk heat. Phase shifting interferometry reveals that the surface roughness decreases with increasing IR heating.

The continuation in effect of China's most-favored-nation status with the United States is contingent principally on the maintenance in force of the waiver of full compliance with the requirements of the freedom-of-emigration ("Jackson-Vanik") amendment of the Trade Act of 1974. Waivers and their underlying authority must be extended annually.

The {open_quotes}Cone-GC{close_quotes} was developed in response to a need for down hole, in-situ characterization of volatile organics within the soil profile, in the vadose zone, or a water headspace. A design based on the use of a miniature gas chromatograph was selected since it was believed that such an instrument would be adaptable to a broad range of analytes and could be used in complex, real-world situations where the environmental contaminants to be monitored may exist in complex mixtures with other vapors. The Cone-GC is versatile and will also fit within many other soil probes, hole liners, and minimally intrusive emplacement systems where small size in addition to high performance are required. The Cone-GC was designed to allow environmental specialists for the first time to obtain immediate, in-situ chemical measurements in a soil probe and to make real-time, on-site decisions that will greatly reduce the time (and cost) of site characterization and remediation. It will no longer be necessary to collect samples (using long sampling lines that may become contaminated), send them to an off-site laboratory for analysis, and then wait hours or days for results.

Efforts toward quantitation of the sulfur removed from coal in the reaction Coal(S) + excess PBu3 {yields}heat Coal + SPBu3 /PBu3 by column chromatography of the products followed by weighing the SPBu3 and vacuum distillation of the SPBu3/PBu3 mixture followed by gas chromatographic analysis are described. The first method failed, but the latter is more successful. It has been discovered that para-chloro phenol catalyzes the removal of sulfur from dibenzothiophene by PBu3 under mild conditions.

The purpose of this Site Environmental Report (SER) is to characterize site environmental management performance, confirm compliance with environmental standards and requirements, and highlight significant programs and efforts. Included in this report is a description of each site`s environment, an overview of the Strategic Petroleum Reserve (SPR) environmental program, and a recapitulation of special environmental activities and events associated with each SPR site during 1995. Two of these highlights include decommissioning of 3 the weeks Island facility, involving the disposition of 11.6 million m{sup 3} (73 million barrels) of crude oil inventory, as well as the degasification of over 4.5 million m{sup 3} (30 million barrels) of crude oil inventory at the Bryan Mound and West Hackberry facilities. The decision to decommission the weeks Island facility is a result of diminishing mine integrity from ground water intrusion. Transfer of Weeks Island oil began in November, 1995 with 2.0 million m{sup 3} (12.5 million barrels) transferred by December 31, 1995. Degasifying the crude oil is a major pollution prevention initiative because it will reduce potentially harmful emissions that would occur during oil movements by three or more orders of magnitude. Spills to the environment, another major topic, indicates a positive trend. …

Numerous reports have indicated that contamination at DOE facilities is widespread and pervasive. Existing technology is often too costly or ineffective in remediating these contamination problems. An effective method to address one class of contamination, petroleum hydrocarbons, is in situ bioremediation. This project was designed to provide tools and approaches for increasing the reliability of in situ bioremediation. An example of the recognition within DOE for developing these tools is in the FY-1995 Technology Development Needs Summary of the Office of Technology Development of the US DOE. This document identifies specific needs addressed by this research. For example, Section 3.3 Need Statement IS-3 identifies the need for a {open_quotes}Rapid method to detect in situ biodegradation products.{close_quotes} Also, BW-I identifies the need to recognize boundaries between clean and contaminated materials and soils. Metabolic activity could identify these boundaries. Measuring rates of in situ microbial activity is critical to the fundamental understanding of subsurface microbiology and in selecting natural attenuation as a remediation option. Given the complexity and heterogeneity of subsurface environments, a significant cost incurred during bioremediation is the characterization of microbial activity, in part because so many intermediate end points (biomass, gene frequency, laboratory measurements of activity, etc.) must be …
