Public Schools: Insufficient Research to Determine Effectiveness of Selected Private Education Companies

Description: A letter report issued by the General Accounting Office with an abstract that begins "In recent years, local school districts and traditional public schools have taken various initiatives to improve failing schools. School districts and charter schools are increasingly contracting with private, for-profit companies to provide a range of education and management services to schools. In the District of Columbia, some public schools contract with three such companies: Edison Schools, Mosaica Edu… more

Defense Infrastructure: Fire Protection at Philadelphia Naval Business Center Meets Response Standards

Description: A letter report issued by the General Accounting Office with an abstract that begins "When the Department of Defense closed military installations as a part of the base realignment and closure process and transferred properties to public and private ownership, it in some cases retained a portion of an installation as a military enclave.

Geochemistry Model Abstraction and Sensitivity Studies for the 21 PWR CSNF Waste Package

Description: The CSNF geochemistry model abstraction, as directed by the TWP (BSC 2002b), was developed to provide regression analysis of EQ6 cases to obtain abstracted values of pH (and in some cases HCO{sub 3}{sup -} concentration) for use in the Configuration Generator Model. The pH of the system is the controlling factor over U mineralization, CSNF degradation rate, and HCO{sub 3}{sup -} concentration in solution. The abstraction encompasses a large variety of combinations for the degradation rates of m… more

3D Geological Modeling of the General Separations Area, Savannah River Site: A Preliminary Workflow and Model

Description: The Savannah River Site, located in South Carolina, contains nuclear defense products and nuclear waste byproducts as result of national defense operations dating to the 1950s. The facility has been the subject of a variety of scientific investigations focusing on potential groundwater transportation of nuclides and other hazardous materials through the different aquifers within the air. The area of particular interest, and the subject of this report, is the General Separations Area.

LiFePO{sub 4}/gel/natural graphite cells for the BATT program

Description: LiFePO{sub 4}/gel/natural graphite (NG) cells have been prepared and cycled under a fixed protocol for cycle and calendar life determination. Cell compression of 10 psi was found to represent an optimal balance between cell impedance and the first cycle losses on the individual electrodes with the gel electrolyte. Cells with a Li anode showed capacities of 160 and 78 mAh/g-LiFePO{sub 4} for C/25 and 2C discharge rates, respectively. Rapid capacity and power fade were observed in the LiFePO{sub … more

Experimental Studies of the Stimulated Brillouin Scattering Instability in the Saturated Regime

Description: An experimental study of the stimulated Brillouin scattering (SBS) instability has investigated the effects of velocity gradients and kinetic effects on the saturation of ion-acoustic waves in a plasma. For intensities less than I < 1.5 x 10{sup 15} W cm{sup -2}, the SBS instability is moderated primarily by velocity gradients, and for intensities above this threshold, nonlinear trapping is invoked to saturate the instability. We report direct evidence of detuning of SBS by a velocity gradie… more

Tank Riser Suspension System Conceptual Design

Description: A team of engineers from High Level Waste (HLW), the Savannah River Technology Center (SRTC), and Project Engineering and Construction Division (PE and CD) explored ways of more effectively utilizing the HLW tank's risers during waste removal and closure activities. Currently, some of the risers are being used to store failed and contaminated equipment. To make those risers available for tank operation, failed equipment must be moved out of the tank and relocated or disposed of appropriately. D… more

METHANE de-NOX FOR UTILITY PC BOILERS

Description: The project seeks to develop and validate a new pulverized coal combustion system to reduce utility PC boiler NO{sub x} emissions to 0.15 lb per million Btu or less without post-combustion flue gas cleaning. Work during previous reporting periods completed the design, installation, shakedown and initial PRB coal testing of a 3-million Btu/h pilot system at BBP's Pilot-Scale Combustion Facility (PSCF) in Worcester, MA. Based on these results, modifications to the gas-fired preheat combustor and … more

The Ssart of Run II at CDF

Description: After a hiatus of almost 6 years and an extensive upgrade, Tevatron, the world largest proton-antiproton collider, has resumed the operation for the so called RUN II. In this paper we give a brief overview of the many new features of the Tevatron complex and of the upgraded CDF experiment, and show the presently achieved detector performances as well as highlights of the RUN II physics program in the beauty and electroweak sector.

A variable-focus x-ray compound lens.

Description: Design and fabrication of an x-ray lens assembly for focusing x-ray beams is described. The assembly consists of a number of precisely stacked and aligned aluminum parts. These parts are cut from a long extruded section having sixteen parabolic cavities along its length. The thickness of the wall between adjacent cavities is 0.2 mm. By cutting the assembled parts diagonally as shown below, a variable-focus lens system can be made. Moving the lens horizontally allows the incident beam to pass th… more

PHASE II CALDERON PROCESS TO PRODUCE DIRECT REDUCED IRON RESEARCH AND DEVELOPMENT PROJECT

Description: This project was initially targeted to the making of coke for blast furnaces by using proprietary technology of Calderon in a phased approach, and Phase I was successfully completed. The project was then re-directed to the making of iron units. U.S. Steel teamed up with Calderon for a joint effort which will last 30 months to produce directly reduced iron with the potential of converting it into molten iron or steel consistent with the Roadmap recommendations of 1998 prepared by the Steel Indus… more

Energy Policy: Setting the Stage for the Current Debate

Description: The Bush Administration issued its plan for a national energy policy on May 16, 2001. The plan was controversial, characterized by some as leaner on conservation and renewables than Democratic proposals, and predisposed to trade off environmental considerations to increase supply. Comprehensive energy legislation was introduced in the Senate by both parties by late March (S. 388, S. 389, S. 596, S. 597). Bills reported by several House committees (H.R. 2436, H.R. 2460, H.R. 2511, and H.R. 2587)… more
