Keys to Successful D&D Technology Deployments at the INEEL
Seven improved decontamination and decommissioning (D&D) technologies were successfully deployed at the Idaho National Engineering and Environmental Laboratory (INEEL) during the Accelerated Site Technology Deployment (ASTD) Integrated Decontamination and Decommissioning (ID&D) project. The use of these improved technologies saved the INEEL $462K in fiscal year 1999, and is projected to save about $14M over the next ten years. Since deploying new technologies on D&D projects shows great potential for cost-savings, factors that led to successful deployment have been documented. These factors are described here as they apply to the seven deployments at the INEEL to assist with deployments at other DOE sites.

Low cost methodologies to analyze and correct abnormal production decline in stripper gas wells
The goal of this research program is to develop and deliver a procedure guide of low cost methodologies to analyze and correct problems with stripper wells experiencing abnormal production declines. A study group of wells will provide data to determine the historic frequency of the problem of abnormal production declines in stripper gas wells and the historic frequency of the causes of the production problems. Once the most frequently occurring causes of the production problems are determined, data collection forms and decision trees will be designed to cost-effectively diagnose these problems and suggest corrective action. Finally, economic techniques to solve the most frequently occurring problems will be researched and implemented. These systematic methodologies and techniques will increase the efficiency of problem assessment and implementation of solutions for stripper gas wells. This second quarterly technical report describes the data reduction and methodology to develop data collection forms of pertinent information to assist in analysis of problem wells. The report also describes the procedures to categorize individual well problems. Finally, the report summarizes the frequency of individual well problems.

Marine boundary-layer cloud structure from CM- to KM-scales
The authors analysis of small-scale LWC fluctuations in PVM-100A data from SOCEX-1 supports the still controversial claim that droplet concentration is not everywhere Poissonian. This does not exclude a slow (spectral exponent {beta} = 5/3) low-amplitude component in the variability of droplet number and size distribution. We believe the cause of the excess small-scale LWC variance causing the scale-break at 2--5 m lies in entrainment- and/or-mixing events; such processes maybe related to the intermittency (occasional bursts of variability at the inner-scale) associated with the large-scale multifractality. Comparing exponents obtained for large-scale behavior with those previously obtained from two other field programs, we uncover remarkable similarities between the basic multifractal (i.e., arbitrary-order structure function) properties of LWC in SOCEX, FIRE'87 and ASTEX clouds and those of passively advected scalars in turbulent flows. However, we also find interesting differences between the three kinds of marine cloud cover and with passive scalars but these are in the details of the various multifractal characterizations (inner and outer scales, high-order scaling). To reproduce these statistical behaviors defines a quantitatively-precise challenge for the cloud-modeling community.

Material Limits Adjusted by a Modified Airborne Release Fraction
This paper will discuss the methods used at a depleted uranium facility to develop a hazard categorization and a limiting condition for operation (LCO) for the inventory based on increased Category 2 threshold quantity values (TV) from DOE Standard 1027-92. A revision to the safety analysis report (SAR) for a Category 3 depleted uranium facility was required to meet current methodologies and isotope content. The previous SAR first approved in 1992, allowed an inventory of depleted uranium that exceeded the Category 2 threshold quantity values in the material storage warehouses using an accident analysis methodology for final hazard categorization. New information regarding the isotopic content of the depleted uranium required an updated hazard categorization evaluation. The DOE Standard 1027-92 requires the evaluation to be based on inventory (Reference 1, 3.1, page 5), therefore, the previous method of performing a hazard consequence and probability analysis could not be used. The standard (1027) requires a facility to be designated as a Category 3 Nuclear facility when the inventory levels in the facility, or facility segments, are greater than Category 3 thresholds and below Category 2 thresholds. A Category 2 Nuclear Facility requires a more in depth hazard and accident analysis. Our categorization …

Measurement of a Weak Polarization Sensitivity to the Beam Orbit of the CEBAF Accelerator
An accelerator-based experiment was performed using the CEBAF accelerator of the Thomas Jefferson National Accelerator Facility to investigate a predicted sensitivity of the beam polarization to the vertical betatron orbit in the recirculation arcs. This is the first measurement of any such effect at CEBAF, and provides information about the polarized beam delivery performance of the accelerator. A brief description of the accelerator is given, followed by the experimental methods used and the relevant issues involved in measuring a small ({approximately} 10{sup {minus}2}) change in the beam polarization. Results of measurements of the polarization sensitivity parameters and the machine energy by polarization transport techniques are presented. The parameters were obtained by measurement of the strength of the effect as a function of orbit amplitude and spin orientation, to confirm the predicted coupling between the spin orientation and the quadrupole fields in the beam transport system. This experiment included characterizing the injector spin manipulation system and 5 MeV Mott polarimeter, modeling of the polarization transport of the accelerator, installation of magnets to create a modulated orbit perturbation in a single recirculation arc, and detailed studies of the Hall C Moeller polarimeter.

MERCURY SPECIATION SAMPLING AT NEW CENTURY ENERGY'S VALMONT STATION
The 1990 Clean Air Act Amendments required the U.S. Environmental Protection Agency (EPA) to determine whether the presence of mercury in the stack emissions from fossil fuel-fired electric utility power plants poses an unacceptable public health risk. EPA's conclusions and recommendations were presented in the ''Mercury Study Report to Congress'' and ''Study of Hazardous Air Pollutant Emissions from Electric Utility Steam Generating Units''. The first report addressed both the human health and environmental effects of anthropogenic mercury emissions, while the second addressed the risk to public health posed by the emission of mercury and other hazardous air pollutants from steam electric generating units. Although these reports did not state that mercury controls on coal-fired electric power stations would be required given the current state of the art, they did indicate that the EPA views mercury as a potential threat to human health. Therefore, it was concluded that mercury controls at some point may be necessary. EPA also indicated that additional research/information was necessary before any definitive statement could be made. In an effort to determine the amount and types of mercury being emitted into the atmosphere by coal-fired power plants, EPA in late 1998 issued an information collection request (ICR) …

Microcalorimetry and the transition-edge sensor
Many scientific and industrial applications call for quantum-efficient high-energy-resolution microcalorimeters for the measurement of x rays. The applications driving the development of these detectors involve the measurement of faint sources of x rays in which few photons reach the detector. Interesting astrophysical applications for these microcalorimeters include the measurement of composition and temperatures of stellar atmospheres and diffuse interstellar plasmas. Other applications of microcalorimeter technology include x-ray fluorescence (XRF) measurements of industrial or scientific samples. We are attempting to develop microcalorimeters with energy resolutions of several eV because many sources (such as celestial plasmas) contain combinations of elements producing emission lines spaced only a few eV apart. Our microcalorimeters consist of a metal-film absorber (250 {micro}m x 250{micro}m x 3 {micro}m of copper) coupled to a superconducting transition-edge-sensor (TES) thermometer. This microcalorimeter demonstrated an energy resolution of 42 eV (FWHM) at 6 keV, excellent linearity, and showed no evidence of position dependent response. The response of our microcalorimeters depends both on the temperature of the microcalorimeter and on the electrical current conducted through the TES thermometer. We present a microcalorimeter model that extends previous microcalorimeter theory to include additional current dependent effects. The model makes predictions about the effects of …

MINIMIZATION OF NO EMISSIONS FROM MULTI-BURNER COAL-FIRED BOILERS
Reduction of NO{sub x} emission is an important environmental issue in pulverized coal combustion. Final emissions of NO{sub x} are strongly affected by the nitrogen release during devolatilization, which is the first stage of coal combustion. The most cost-effective approach to NO{sub x} reduction is air-staging which can also operate with additional down-stream techniques such as reburning [1]. Air staging promotes the conversion of NO{sub x} precursors (HCN, NH{sub 3}, etc.) to N{sub 2} by delaying the oxygen supply to the greatest extent when those nitrogen species are released during devolatilization. Such a delay gives the primary volatiles a chance to undergo secondary reactions, including tar cracking and soot formation. Secondary reactions of volatiles largely determine the fate of the ultimate NO{sub x} production from pyrolysis, therefore a detailed investigation into the transformation of nitrogen species during secondary reactions and effects of soot on nitrogen release is critical for design and implementation of new pollution control strategies. Current nitrogen models (including the CPD model at BYU) only simulate the nitrogen release during primary pyrolysis, which happens at low temperatures. This project helps to build a nitrogen release model that accounts for secondary reactions and the effects of soot at temperatures …

MINIMIZATION OF NO EMISSIONS FROM MULTI-BURNER COAL-FIRED BOILERS
Coal continues to be one of the principal energy sources for electric power generation in the United States. One of the biggest environmental challenges involved with coal utilization is the reduction of nitrogen oxides (NO{sub x}) formed during coal combustion. The most economical method of NO{sub x} abatement in coal combustion is through burner modification. Air-staging techniques have been widely used in the development of low-NO{sub x} pulverized coal burners, promoting the conversion of NO{sub x} to N{sub 2} by delaying the mixing in the fuel-rich zone near the burner inlet. Previous studies have looked at the mechanisms of NO{sub x} evolution at relatively low temperatures where primary pyrolysis is dominant, but data published for secondary pyrolysis in the pulverized coal furnace are scarce. In this project, the nitrogen evolution behavior during secondary coal pyrolysis will be explored. The end result will be a complete model of nitrogen evolution and NO{sub x} precursor formation due to primary and secondary pyrolysis.
