2-Page Summary for Neptunium solubility in the Near-field Environment of A Proposed Yucca Mountain Repository

Description: The total system performance assessment (TSPA) for the proposed repository at Yucca Mountain, NV, includes a wide variety of processes to evaluate the potential release of radionuclides from the Engineered Barrier System into the unsaturated zone of the geosphere. The principal processes controlling radionuclide release and mobilization from the waste forms are captured in the model to assess the dissolved concentrations of radionuclides in the source-term. The TSPA model of the source-term inc… more

21-PWR Waste Package Side and End Impacts

Description: The objective of this calculation is to determine the structural response of a 21-Pressurized Water Reactor (PWR) spent nuclear fuel waste package impacting an unyielding surface. A range of initial velocities and initial angles between the waste package and the unyielding surface is studied. The scope of this calculation is limited to estimating the area of the outer shell (OS) where the residual stress exceeds a given limit (hereafter ''damaged area''). The stress limit is defined as a fracti… more

Agricultural Disaster Assistance

Description: The U.S. Department of Agriculture (USDA) offers several permanently authorized programs to help farmers recover financially from a natural disaster, including federal crop insurance, the non-insured assistance program and emergency disaster loans. In recent years, Congress frequently has made supplemental financial assistance available to farmers and ranchers on an ad-hoc basis, most notably in the form of direct crop disaster payments and emergency livestock assistance. Congress provided an e… more

Agriculture: Previewing a Farm Bill

Description: Most provisions of the current “farm bill,” the Farm Security and Rural Investment Act (FSRIA) of 2002 (P.L. 107-171), do not expire until 2007. Nonetheless, various policy developments have brought farm bill programs into play during the 109th Congress. For example, the FY2006 budget resolution (H.Con.Res. 95) directs the House and Senate Agriculture Committees to find five-year savings of $3 billion from programs under their jurisdiction. Hearings on a 2007 farm bill itself could begin later … more

AIDS in Africa

Description: Sub-Saharan Africa has been far more severely affected by AIDS than any other part of the world. The United Nations reports that 24.5 million adults and children are infected with the HIV virus in the region, which has about 10% of the world's population but more than 64% of the worldwide total of infected people. This report discusses this issue in detail, including the cause of the African AIDS epidemic, the social and economic consequences, response and treatment, and U.S. policy.

Air Quality: Multi-Pollutant Legislation in the 109th Congress

Description: This report discusses air pollutants (petroleum, natural gas, and coal), which account for about two-thirds of U.S. electricity generation. These gases include several pollutants that directly pose risks to human health and welfare. The report also discusses the utilities that are subject to an array of environmental regulations.

Air Traffic Control: Characteristics and Performance of Selected International Air Navigation Service Providers and Lessons Learned from Their Commercialization

Description: A letter report issued by the Government Accountability Office with an abstract that begins "In the past, governments worldwide owned, operated, and regulated air navigation services, viewing air traffic control as a governmental function. But as nations faced increasing financial strains, many governments decided to shift the responsibility to an independent air navigation service provider (ANSP) that operates as a business. As of March 2005, 38 nations worldwide had commercialized their air n… more

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: April-June 2005

Description: Devonian gas shales underlie approximately two-thirds of Kentucky. In the shale, natural gas is adsorbed on clay and kerogen surfaces. This is analogous to methane storage in coal beds, where CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. Drill cuttings from the Kentucky Geological Survey Well Sample and Core Library were sampled to determine CO{sub 2} and CH{sub 4} adsorption isotherms. Sidewall core samples wer… more

Andean-U.S. Free-Trade Agreement Negotiations

Description: In November 2003, the Bush Administration announced that it intended to begin negotiations on a free-trade agreement (FTA) with these nations, which would reduce and eliminate foreign barriers to trade and investment, support democracy, and fight drug activity. This report briefly discusses this announcement, as well as the major issues and concerns relating to negotiation, and the Andean Trade Preference Act (ATPA), the FTA's predecessor.

Appendix D-16A Building 515 Waste Accumulation Area

Description: The B-515 WAA is located in the southeast quadrant of the LLNL Main Site (see Figure D-1) along the west side of Building 515 (B-515). Hazardous wastes may be stored at the B-515 WAA for 90 days or less, until transferred to the appropriate Radioactive and Hazardous Waste Management (RHWM) facility or other permitted treatment, storage or disposal facility (TSDF). The design storage capacity of this WAA is 4,840 gallons. This appendix is designed to provide information specific to the Building … more

Aromatics Oxidation and Soot Formation in Flames

Description: This project is concerned with the kinetics and mechanisms of aromatics oxidation and the growth process to polycyclic aromatic hydrocarbons (PAH) of increasing size, soot and fullerenes formation in flames. The overall objective of the experimental aromatics oxidation work is to extend the set of available data by measuring concentration profiles for decomposition intermediates such as phenyl, cyclopentadienyl, phenoxy or indenyl radicals which could not be measured with molecular-beam mass sp… more

ASH REDISTRIBUTION FOLLOWING A POTENTIAL VOLCANIC ERUPTION AT YUCCA MOUNTAIN

Description: The redistribution of contaminated tephra by hillslope, fluvial, and pedologic processes is a poorly-constrained but important aspect of evaluating the radiological dose from an unlikely volcanic eruption at Yucca Mountain (YM). To better evaluate this hazard, we developed a spatially distributed, numerical model of tephra redistribution that integrates contaminated tephra from hill slopes and active channels, mixes it with clean sediment in the channel system, distributes it on the fan, and mi… more

BI-LAYER p-n JUNCTION INTERCONNECTIONS FOR COAL BASED SOLID OXIDE FUEL CELLS

Description: In this report, a new approach for lower operating temperature solid oxide fuel cells (SOFCs) interconnections (IC) consisting of a bi-layer structure is proposed and analyzed. The bi-layer structure consists of a p-type layer exposed to cathodic gas (air/oxygen) and an n-type layer exposed to anodic gas (fuel). It is theoretically shown that the interfacial oxygen partial pressure which is an important design variable, is dependent primarily on the oxygen partial pressure gradient across the I… more
