Highway Safety: Improved Monitoring and Oversight of Traffic Safety Data Program Are Needed

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Auto crashes kill or injure millions of people each year. Information about where and why such crashes occur is important in reducing this toll, both for identifying particular hazards and for planning safety efforts at the state and federal levels. Differences in the quality of state traffic data from state to state, however, affect the usability of data for these purposes. The National Highway Traffic… more

Social Security Disability: Improved Processes for Planning and Conducting Demonstrations May Help SSA More Effectively Use Its Demonstration Authority

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Since 1980, the Congress has required the Social Security Administration (SSA) to conduct demonstration projects to test the effectiveness of possible program changes that could encourage individuals to return to work and decrease their dependence on Disability Insurance (DI) benefits. To conduct these demonstrations, the Congress authorized SSA, on a temporary basis, to waive certain DI and Medicare pr… more

Updates to the ORIGEN-S Cross-Section Libraries Using ENDF-VI, EAF-99, and FENDL-2.0

Description: The standard cross-section library for light-water reactor (LWR) analyses used by the ORIGEN-S depletion and decay code has been extensively updated. This work entailed the development of broad multigroup neutron cross sections for ORIGEN-S from several sources of pointwise continuous-energy cross-section evaluations, including the U.S. Evaluated Nuclear Data Files ENDF/B-VI Release 7, the Fusion Evaluated Nuclear Data Library FENDL-2.0, and the European Activation File EAF-99. The pointwise cr… more

Automobile and Light Truck Fuel Economy: The CAFE Standards

Description: This report discusses energy legislation pertaining to fuel standards. The current corporate average fuel economy standard (CAFE) is 27.5 miles per gallon (mpg) for passenger automobiles and 20.7 mpg for light trucks (scheduled to increase to 22.2 mpg in model year [MY] 2007), a classification that also includes sport utility vehicles (SUVs). Congress had included language in the FY1996-FY2001 Transportation Appropriations prohibiting the use of appropriated funds for any rulemaking on CAFE, ef… more

Magnetization reversal behaviour of nanogranular CoCrPt alloy thinfilms studied with magnetic transmission X-ray microscopy

Description: The angular dependence of dissociative electron attachment (DEA) to polyatomic targets is formulated in the local complex potential model, under the assumption that the axial recoil approximation describes the dissociation dynamics. An additional approximation, which is found to be valid in the case of H{sub 2}O but not in the case of H{sub 2}S, makes it possible to describe the angular dependence of DEA solely from an analysis of the fixed-nuclei entrance amplitude, without carrying out nuclea… more

Minijet Deformation and Charge-independent Two-particleCorrelations on Momentum Subspace (eta,phi) In Au-Au Collisions atsqrt(sNN) = 130 GeV

Description: We present first measurements of charge-independent correlations on momentum-space difference variables {eta}{sub 1}-{eta}{sub 2} (pseudorapidity) and {phi}{sub 1}-{phi}{sub 2} (azimuth) for charged primary hadrons with transverse momentum within 0.15 {le} p{sub t} {le} 2 GeV/c and |{eta}| {le} 1.3 from Au-Au collisions at {radical}s{sub NN} = 130 GeV. We observe strong charge-independent correlations associated with minijets and elliptic flow. The width of the minijet peak on {eta}{sub 1}-{eta… more

The South Pole Telescope

Description: A new 10 meter diameter telescope is being constructed for deployment at the NSF South Pole research station. The telescope is designed for conducting large-area millimeter and sub-millimeter wave surveys of faint, low contrast emission, as required to map primary and secondary anisotropies in the cosmic microwave background. To achieve the required sensitivity and resolution, the telescope design employs an off-axis primary with a 10 m diameter clear aperture. The full aperture and the associa… more

Processing Tritiated Water at the Savannah Rivver Site: A Production Scale Demonstration

Description: The Palladium Membrane Reactor (PMR) process was installed in the Tritium Facilities at the Savannah River Site to perform a production-scale demonstration for the recovery of tritium from tritiated water adsorbed on molecular sieve (zeolite). Unlike the current recovery process that utilizes magnesium, the PMR offers a means to process tritiated water in a more cost effective and environmentally friendly manner. The design and installation of the large-scale PMR process was part of a collabora… more

VUV Spectroscopy in DIII-D Divertor

Description: The research carried out on this grant was motivated by the high power emission from the CIV doublet at 155 nm in the DIII-D divertor and to study the characteristics of the radiative divertor. The radiative divertor is designed to reduce the heat load to the target plates of the divertor by reducing the energy in the divertor plasma using upstream scrape-off-layer (SOL) radiation. In some cases, particularly in Partially Detached Divertor (PDD) operations, this emission accounts for more than … more

Quantifying Cost Risk Early in the Life Cycle

Description: A new method for analyzing life cycle cost risk on large programs is presented that responds to an increased emphasis on improving sustainability for long-term programs. This method provides better long-term risk assessment and risk management techniques. It combines standard Monte Carlo analysis of risk drivers and a new data-driven method developed by the BMDO. The approach permits quantification of risks throughout the entire life cycle without resorting to difficult to support subjective me… more

Comparison of Streak Tube Performance

Description: The performance of four streak tubes in six streak camera configurations is reported. Evaluations were made as part of a search for a streak tube to replace the obsolete RCA C73435 used in the ICF Program's optical streak cameras. Characteristics measured include linearity, spatial and temporal resolution, line-spread function, contrast transfer ratio (CTR), and dynamic range. Tubes evaluated are the RCA C73435, Photonis P510, Photek ST-Y, and Hamamatsu N8059. The RCA C73435 was evaluated in th… more

Development of odd-Z-projectile reactions for transactinide element synthesis

Description: The development of new odd-Z-projectile reactions leading to the production of transactinide elements is described. The cross section of the even-Z-projectile 208Pb(64Ni, n)271Ds reaction was measured at two new energies using the Berkeley Gas-filled Separator at the Lawrence Berkeley National Laboratory 88-Inch Cyclotron. In total, seven decay chains attributable to 271Ds were observed. These data, combined with previous results, establish an excitation function for the production of 271Ds. Th… more

Digestion of Crystalline Silicotitanate (CST)

Description: Researchers tested methods for chemically dissolving crystalline silicotitanate (CST) as a substitute for mechanical grinding to reduce particle size before vitrification. Testing used the commercially available form of CST, UOP IONSIV(R) IE-911. Reduction of the particle size to a range similar to that of the glass frit used by the Defense Waste Processing Facility (DWPF) could reduce problems with coupling cesium ion exchange to the vitrification process. This study found that IONSIV(R) IE-91… more
