Intercity Passenger Rail: National Policy and Strategies Needed to Maximize Public Benefits from Federal Expenditures

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Intercity passenger rail service is at a critical juncture in the United States. Amtrak, the current service provider, requires $1 billion a year in federal subsidies to stay financially viable but cannot keep pace with its deteriorating infrastructure. At the same time, the federal government faces growing fiscal challenges. To assist the Congress, GAO reviewed (1) the existing U.S. system and its pote… more

Analysis of Data for Exports Regulated by the Department of Commerce

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "In light of the September 2001 terror attacks, we were asked to examine the Department of Commerce's Bureau of Industry and Security's (BIS) dual-use export control system. We reported our findings in a June 26, 2006, report, saying that BIS has not systematically evaluated the overall effectiveness and efficiency of the dual-use export control system. Specifically, we reported that BIS has not conducted… more

Prevalence of Domestic Violence, Sexual Assault, Dating Violence, and Stalking

Description: Correspondence issued by the Government Accountability Office with an abstract that begins "In hearings conducted between 1990 and 1994, Congress noted that violence against women was a problem of national scope and that the majority of crimes associated with domestic violence, sexual assault, and stalking were perpetrated against women. These hearings culminated in the enactment of the Violence Against Women Act (VAWA) in 1994 to address these issues on a national level. VAWA established grant… more

Next Generation Air Transportation System: Progress and Challenges Associated with the Transformation of the National Airspace System

Description: A letter report issued by the Government Accountability Office with an abstract that begins "In 2003, Congress created the Joint Planning and Development Office (JPDO) to plan for and coordinate, with federal and nonfederal stakeholders, a transformation from the current air traffic control system to the "next generation air transportation system" (NGATS) by 2025. Housed within the Federal Aviation Administration (FAA), JPDO has seven partner agencies: the Departments of Transportation, Commerc… more

Global War On Terrorism: Fiscal Year 2006 Obligation Rates Are Within Funding Levels and Significant Multiyear Procurement Funds Will Likely Remain Available for Use in Fiscal Year 2007

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Because of broad congressional interest, GAO is examining the costs of military operations in support of the Global War on Terrorism (GWOT) under the Comptroller General's authority to conduct evaluations on his own initiative. In September 2005, GAO reported the Department of Defense (DOD) cannot ensure reported GWOT obligations are complete, reliable, and accurate, and recommended improvements. In thi… more

End-Stage Renal Disease: Bundling Medicare's Payment for Drugs with Payment for All ESRD Services Would Promote Efficiency and Clinical Flexibility

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Medicare covers dialysis--a process that removes excess fluids and toxins from the bloodstream--for most individuals with end-stage renal disease (ESRD), a condition of permanent kidney failure. The Centers for Medicare & Medicaid Services (CMS) pays for certain dialysis services under a type of bundled rate, called a composite rate, and, for certain dialysis-related drugs, pays a separate rate per dose… more

Calculation of Photoneutrons from Varian Clinac Accelerators and Their Transmissions in Materials

Description: Monte Carlo calculations of the giant-dipole-resonance photoneutrons (GRN) around the Varian Clinac 2100C/2300C medical accelerator heads (10-20 MV modes) were made using the coupled EGS4-MORSE code. The actual head materials and geometries were simulated in great detail using the Combinatorial Geometry facility of MORSE. The neutron production (i.e., sites and yields) was calculated with EGS4 and, then, the neutron transport in the accelerator head was done with MORSE. Both the evaporation and… more

Application of Neutron-Absorbing Structural-Amorphous Metal (SAM) Coatings for Spent Nuclear Fuel (SNF) Container to Enhance Criticality Safety Controls

Description: Spent nuclear fuel contains fissionable materials ({sup 235}U, {sup 239}Pu, {sup 241}Pu, etc.). Neutron multiplication and the potential for criticality are enhanced by the presence of a moderator during cask loading in water, water incursion in accidents conditions during spent fuel storage or transport. To prevent nuclear criticality in spent fuel storage, transportation, and during disposal, neutron-absorbing materials (or neutron poisons, such as borated stainless steel, Boral{trademark}, M… more

Simulations of X-ray Emission from Omega Fill Tube Experiments

Description: The capsules used in ignition experiments on the National Ignition Facility (NIF) laser will have a layer of frozen DT inside a low-Z shell. Liquid DT will be injected through a narrow fill tube that penetrates the shell and frozen in place. The fill tube is a perturbation on the surface of the capsule and hydrodynamic instabilities will cause this perturbation to grow during an implosion. Experiments to investigate the growth of perturbations due to fill tubes have been carried out on the Omeg… more

Treatability Study of In Situ Technologies for Remediation of Hexavalent Chromium in Groundwater at the Puchack Well Field Superfund Site, New Jersey

Description: This treatability study was conducted by Pacific Northwest National Laboratory (PNNL), at the request of the U. S. Environmental Protection Agency (EPA) Region 2, to evaluate the feasibility of using in situ treatment technologies for chromate reduction and immobilization at the Puchack Well Field Superfund Site in Pennsauken Township, New Jersey. In addition to in situ reductive treatments, which included the evaluation of both abiotic and biotic reduction of Puchack aquifer sediments, natural… more

Stratospheric Relaxation in IMPACT's Radiation Code

Description: While Impact incorporates diagnostic radiation routines from our work in previous years, it has not previously included the stratospheric relaxation required for forcing calculations. We have now implemented the necessary changes for stratospheric relaxation, tested its stability, and compared the results with stratosphere temperatures obtained from CAM3 met data. The relaxation results in stable temperature profiles in the stratosphere, which is encouraging for use in forcing calculations. It … more

Comments on cathode contaminants and the LBNL test stand

Description: This report collects information on cathode contaminants we have gathered in the process of operating the LBNL DARHT cathode test stand. Information on contaminants is compiled from several sources. The attachment, ''Practical Aspects of Modern Dispenser Cathodes'', is from Heat Wave Corp. (TB-134) and was originally published in Microwave Journal, September 1979. Cathode contamination depends on both material choices and residual gases. Table 1 of TB-134 lists materials that can poison dispens… more

Neutron Production by Muon Spallation I: Theory

Description: We describe the physics and codes developed in the Muon Physics Package. This package is a self-contained Fortran90 module that is intended to be used with the Monte Carlo package MCNPX. We calculate simulated energy spectra, multiplicities, and angular distributions of direct neutrons and pions from muon spallation.

No-Core Shell Model for A = 47 and A = 49

Description: We apply the no-core shell model to the nuclear structure of odd-mass nuclei straddling {sup 48}Ca. Starting with the NN interaction, that fits two-body scattering and bound state data, we evaluate the nuclear properties of A = 47 and A = 49 nuclei while preserving all the underlying symmetries. Due to model space limitations and the absence of three-body interactions, we incorporate phenomenological interaction terms determined by fits to A = 48 nuclei in a previous effort. Our modified Hamilt… more
