Tampa Electric Neural Network Sootblowing
Boiler combustion dynamics change continuously due to several factors including coal quality, boiler loading, ambient conditions, changes in slag/soot deposits and the condition of plant equipment. NO{sub x} formation, Particulate Matter (PM) emissions, and boiler thermal performance are directly affected by the sootblowing practices on a unit. As part of its Power Plant Improvement Initiative program, the US DOE is providing cofunding (DE-FC26-02NT41425) and NETL is the managing agency for this project at Tampa Electric's Big Bend Station. This program serves to co-fund projects that have the potential to increase thermal efficiency and reduce emissions from coal-fired utility boilers. A review of the Big Bend units helped identify intelligent sootblowing as a suitable application to achieve the desired objectives. The existing sootblower control philosophy uses sequential schemes, whose frequency is either dictated by the control room operator or is timed based. The intent of this project is to implement a neural network based intelligent soot-blowing system, in conjunction with state-of-the-art controls and instrumentation, to optimize the operation of a utility boiler and systematically control boiler fouling. Utilizing unique, on-line, adaptive technology, operation of the sootblowers can be dynamically controlled based on real-time events and conditions within the boiler. This could …

TECHNICAL EVALUATION OF REMEDIATION TECHNOLOGIES FOR PLUTONIUM-CONTAMINATED SOILS AT THE NEVADA TEST SITE (NTS)
The Clemson Environmental Technologies Laboratory (CETL) was contracted by the National Energy Technology Center to evaluate technologies that might be used to reduce the volume of plutonium-contaminated soil at the Nevada Test Site. The project has been systematically approached. A thorough review and summary was completed for: (1) The NTS soil geological, geochemical and physical characteristics; (2) The characteristics and chemical form of the plutonium that is in these soils; (3) Previous volume reduction technologies that have been attempted on the NTS soils; (4) Vendors with technology that may be applicable; and (5) Related needs at other DOE sites. Soils from the Nevada Test Site were collected and delivered to the CETL. Soils were characterized for Pu-239/240, Am-241 and gross alpha. In addition, wet sieving and the subsequent characterization were performed on soils before and after attrition scrubbing to determine the particle size distribution and the distribution of Pu-239/240 and gross alpha as a function of particle size. Sequential extraction was performed on untreated soil to provide information about how tightly bound the plutonium was to the soil. Magnetic separation was performed to determine if this could be useful as part of a treatment approach. Using the information obtained from …

TWENTY-YEAR PLANNING STUDY FOR THE RELATIVISTIC HEAVY ION COLLIDER FACILITY AT BROOKHAVEN NATIONAL LABORATORY.
At the request of DOE's Office of Nuclear Physics (ONP), Brookhaven National Laboratory (BNL) has created this planning document to assemble and summarize a planning exercise that addresses the core scientific thrust of the Relativistic Heavy Ion Collider (RHIC) for the next twenty years and the facilities operation plan that will support this program. The planning work was carried out by BNL in close collaboration with the RHIC user community and within budgetary guidelines for the next five years supplied by the ONP. The resulting plans were reviewed by the BNL High Energy and Nuclear Physics Program Advisory Committee (PAC) at a special RHIC planning meeting held in December 2003. Planning input from each of the four RHIC experimental collaborations was absolutely central to the preparation of this overall Laboratory plan. Each collaboration supplied two key documents, a five-year ''Beam Use Proposal'' and a ten-year ''Decadal Plan''. These plans are posted on the BNL website http://www.bnl.gov/henp/, along with other planning documents germane to this paper, such as the complete written reports from the August and December 2003 PAC meetings that considered the five-year and decadal planning documents of the four RHIC collaborations and offered advice and commentary on these plans. …

Analytical Characterization of the Thorium Nitrate Stockpile
For several years, Oak Ridge National Laboratory (ORNL) has been supporting the Defense Logistics Agency-Defense National Stockpile Center with stewardship of a thorium nitrate (ThN) stockpile. The effort for fiscal year 2002 was to prepare a sampling and analysis plan and to use the activities developed in the plan to characterize the ThN stockpile. The sampling was performed in June and July 2002 by RWE NUKEM with oversight by ORNL personnel. The analysis was performed by Southwest Research Institute of San Antonio, Texas, and data validation was performed by NFT, Inc., of Oak Ridge, Tennessee. Of the {approx} 21,000 drums in the stockpile, 99 were sampled and 53 were analyzed for total metals composition, radiological constituents (using alpha and gamma spectrometry), and oxidizing characteristics. Each lot at the Curtis Bay Depot was sampled. Several of the samples were also analyzed for density. The average density of the domestic ThN was found to be 1.89 {+-} 0.08 g/cm{sup 3}. The oxidizer test was performed following procedures issued by the United Nations in 1999. Test results indicated that none of the samples tested was a Division 5.1 oxidizer per Department of Transportation definition. The samples were analyzed for total metals following the …

Approximate Thermodynamics State Relations in Partially Ionized Gas Mixtures
In practical applications, the thermodynamic state relations of partially ionized gas mixtures are usually approximated in terms of the state relations of the pure partially ionized constituent gases or materials in isolation. Such approximations are ordinarily based on an artificial partitioning or separation of the mixture into its constituent materials, with material k regarded as being confined by itself within a compartment or subvolume with volume fraction {alpha}k and possessing a fraction {beta}k of the total internal energy of the mixture. In a mixture of N materials, the quantities {alpha}k and {beta}k constitute an additional 2N--2 independent variables. The most common procedure for determining these variables, and hence the state relations for the mixture, is to require that the subvolumes all have the same temperature and pressure. This intuitively reasonable procedure is easily shown to reproduce the correct thermal and caloric state equations for a mixture of neutral (non-ionized) ideal gases. Here we wish to point out that (a) this procedure leads to incorrect state equations for a mixture of partially ionized ideal gases, whereas (b) the alternative procedure of requiring that the subvolumes all have the same temperature and free electron density reproduces the correct thermal and caloric state …

An Assessment of the Bioaccumulation of PCBs and Chloridane Near the U.S. Department of Energy's Kansas City Plant
Studies conducted by the Missouri Department of Conservation in the late 1980s found high levels of PCBs and chlordane in fish from the Blue River near the Kansas City Plant (KCP). Follow-on biomonitoring studies by Oak Ridge National Laboratory (ORNL) staff from 1991-1993 (Southworth et al. 1992, Ashwood et al. 1993, Ashwood and Peterson 1994), and again on a more limited basis in 1998 (Ashwood 1998), were conducted for the KCP. The studies in the early 1990s characterized concentrations of PCBs and chlordane in fish from Indian Creek, Boone Creek, and the Blue River. These studies concluded that the KCP appears to be one of multiple sources of PCBs to both Indian Creek and the Blue River. There continues to be interest in the potential role of KCP discharges on PCB concentrations in local fish. Elevated PCB concentrations in Indian Creek fish have consistently been found at the location downstream of the NPDES-permitted 002 discharge, which drains a section of the KCP complex. A risk evaluation conducted during 2001 found that some local fish exceeded risk-based guidelines for PCBs. It has been nearly a decade since intensive sampling of fish was conducted within all waters near the KCP (the 1998 …

CAPACITIVE TOMOGRAPHY FOR THE LOCATION OF PLASTIC PIPE
The objective of this program was to develop and test a system that would detect and image buried plastic and ceramic pipe. The system is designed to detect variations in the electric permeability of soil corresponding to the presence of a buried plastic pipe. The Gas Technology Institute (GTI) proposed to develop a compact and inexpensive capacitive tomography-imaging sensor that can be placed on the ground to image objects embedded in the soil. The system provides a coarse image, which allows the operator to identify a buried object's location both horizontally and vertically.

Gasification Evaluation of Gas Turbine Combustion
This report provides a preliminary assessment of the potential for use in gas turbines and reciprocating gas engines of gases derived from biomass by pyrolysis or partial oxidation with air. Consideration was given to the use of mixtures of these gases with natural gas as a means of improving heating value and ensuring a steady gas supply. Gas from biomass, and mixtures with natural gas, were compared with natural gas reformates from low temperature partial oxidation or steam reforming. The properties of such reformates were based on computations of gas properties using the ChemCAD computational tools and energy inputs derived from known engine parameters. In general, the biomass derived fuels compare well with reformates, so far as can be judged without engine testing. Mild reforming has potential to produce a more uniform quality of fuel gas from very variable qualities of natural gas, and could possibly be applied to gas from biomass to eliminate organic gases and condensibles other than methane.
