A letter report issued by the Government Accountability Office with an abstract that begins "The Advanced SEAL Delivery System (ASDS) is a hybrid combatant submersible providing clandestine delivery and extraction of Navy SEALs and equipment in high-threat environments. The first ASDS has had significant performance issues and has cost, to date, over $885 million. In May 2006, Congress requested that GAO review ASDS. This report examines (1) how the Navy managed ASDS risks through its contracts and (2) the status of major technical issues and program restructuring."

Testimony issued by the Government Accountability Office with an abstract that begins "The United States is the largest global food aid donor, accounting for over half of all food aid supplies to alleviate hunger and support development. Since 2002, Congress has appropriated an average of $2 billion per year for U.S. food aid programs, which delivered an average of 4 million metric tons of food commodities per year. Despite growing demand for food aid, rising business and transportation costs have contributed to a 52 percent decline in average tonnage delivered between 2001 and 2006. These costs represent 65 percent of total emergency food aid, highlighting the need to maximize its efficiency and effectiveness. This testimony is based on a recent GAO report that examined some key challenges to the (1) efficiency of U.S. food aid programs and (2) effective use of U.S. food aid."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2002, Congress enacted the Jobs for Veterans Act (JVA), which modified two Department of Labor (Labor) programs that specifically target veteran job seekers: the Disabled Veterans' Outreach Program (DVOP) and the Local Veterans' Employment Representative (LVER) program. However, questions have been raised about the adequacy of performance information on services to veterans by these and other employment programs. In this report, GAO examined (1) the extent to which DVOP and LVER performance information reflects services and outcomes for veterans; (2) the extent to which performance information on veterans paints a clear picture of their use of one-stop services; and (3) what Labor is doing to improve the quality of performance data and better understand program impact and outcomes for veterans."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) relies on a network of DOD and non-DOD infrastructure assets in the United States and abroad so critical that its unavailability could hinder DOD's ability to project, support, and sustain its forces and operations worldwide. DOD established the Defense Critical Infrastructure Program (DCIP) to identify and assure the availability of mission-critical infrastructure. GAO was asked to evaluate the extent to which DOD has (1) developed a comprehensive management plan to implement DCIP and (2) identified, prioritized, and assessed its critical infrastructure. GAO analyzed relevant DCIP documents and guidance and met with officials from more than 30 DOD organizations that have DCIP responsibilities, and with Department of Homeland Security (DHS) officials involved in protecting critical infrastructure."

Correspondence issued by the Government Accountability Office with an abstract that begins "Authoritative bodies have promulgated laws, accounting standards, information system requirements, and related guidance emphasizing the need for accurate and reliable cost information in the federal government. For example, the Chief Financial Officers (CFO) Act of 1990 contains several provisions related to managerial cost accounting (MCA), one of which provides that an agency's CFO should develop and maintain an integrated accounting and financial management system that provides for the development and reporting of cost information. Statement of Federal Financial Accounting Standards (SFFAS) No. 4, Managerial Cost Accounting Concepts and Standards for the Federal Government, and the Joint Financial Management Improvement Program's (JFMIP) Framework for Federal Financial Management Systems established accounting standards and system requirements for MCA information at federal agencies. In addition, the Federal Financial Management Improvement Act of 1996 required, among other things, that CFO Act agencies' systems comply substantially with federal accounting standards and federal financial management systems requirements. In light of the provision related to MCA information in federal agencies, we were asked to review the status of MCA in 10 of the largest civilian agencies. Our objectives were to determine how (1) federal agencies generate …

Testimony issued by the Government Accountability Office with an abstract that begins "In January 2003, GAO designated federal real property as a high-risk area due to long-standing problems with excess and underutilized property, deteriorating facilities, unreliable real property data, and costly space challenges. Federal agencies were also facing many challenges protecting their facilities due to the threat of terrorism. This testimony is based largely on GAO's April 2007 report on real property high-risk issues (GAO-07-349). The objectives of that report were to determine (1) what progress the administration and major real property-holding agencies had made in strategically managing real property and addressing long-standing problems and (2) what problems and obstacles, if any, remained to be addressed."

Other written product issued by the Government Accountability Office with an abstract that begins "Since 2001, the United States has appropriated over $15 billion to help secure, stabilize, and reconstruct Afghanistan. In February 2007, the administration requested $12.3 billion in additional funding to accelerate some of these efforts to prevent the conflict-ridden nation from once again becoming a safe haven for terrorists and from devolving into a narco-state. More than 50 nations, including the United States, and several multilateral organizations are engaged in securing, stabilizing, and reconstructing Afghanistan. Progress has been made in areas such as economic growth, infrastructure development, and training of the Afghan army and police, but after more than 5 years of U.S. and international efforts, the overall security situation in this poor and ethnically diverse country has not improved and, moreover, has deteriorated significantly in the last year. The lack of security limits the success of efforts to stabilize and rebuild Afghanistan. Direct challenges to these efforts include a resurgence of the Taliban, the limited capabilities of Afghan security forces, inadequate infrastructure, limited government capacity, corruption, a largely illiterate and untrained labor force, a dramatic increase in drug production, and a lack of viable licit economic …

The 100-F-36 waste site is the location of the former 108-F Biological Laboratory. The building was closed in 1973, decontaminated, decommissioned, and eventually demolished in 1999. In accordance with this evaluation, the confirmatory sampling results support a reclassification of this site to No Action. The current site conditions achieve the remedial action objectives and the corresponding remedial action goals established in the Remaining Sites ROD. The results of confirmatory sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.

Mineral dissolution rates in the field have been reported to be orders of magnitude slower than those measured in the laboratory, an unresolved discrepancy that severely limits our ability to develop scientifically defensible predictive or even interpretive models for many geochemical processes in the earth and environmental sciences. One suggestion links this discrepancy to the role of physical and chemical heterogeneities typically found in subsurface soils and aquifers in producing scale-dependent rates where concentration gradients develop. In this paper, we examine the possibility that scale-dependent mineral dissolution rates can develop even at the single pore and fracture scale, the smallest and most fundamental building block of porous media. To do so, we develop two models to analyze mineral dissolution kinetics at the single pore scale: (1) a Poiseuille Flow model that applies laboratory-measured dissolution kinetics at the pore or fracture wall and couples this to a rigorous treatment of both advective and diffusive transport, and (2) a Well-Mixed Reactor model that assumes complete mixing within the pore, while maintaining the same reactive surface area, average flow rate, and geometry as the Poiseuille Flow model. For a fracture, a 1D Plug Flow Reactor model is considered in addition to quantify the …

The 116-F-15 waste site is the former location of the 108-F Radiation Crib that was located in the first floor of the 108-F Biological Laboratory. In accordance with this evaluation, the verification sampling results support a reclassification of this site to Interim Closed Out. The current site conditions achieve the remedial action objectives and the corresponding remedial action goals established in the Remaining Sites ROD. The results of verification sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.

It provides the opinion of the Texas Attorney General, Greg Abbott, regarding a legal question submitted for clarification: Authority of a local taxing unit to waive penalties and interest on taxes that became delinquent as a result of an act or omission of an officer, employee, or agent of the appraisal district (RQ-0555-GA)

Prevention of corrosion is a vital goal for the Department of Defense when billions of dollars are spent every year. Corrosion resistant materials have applications in all sort of military vehicles, and more importantly in naval vessels and submarines which come in contact with the seawater. It is known that corrosion resistance property can be improved by the used of structurally designed materials in the amorphous state where the atoms are arranged in a non-periodic fashion and specific atoms, tailored to the required properties can be interjected into the matrix for specific application. The XRD techniques reported here is to demonstrate the optimal conditions for characterization of these materials. The samples, which normally contain different compositions of Fe, Cr, B, Mo, Y, Mn, Si and W, are in the form of powders, ribbons and coatings. These results will be compared for the different forms of the sample which appears to correlate to the cooling rate during sample processing. In most cases, the materials are amorphous or amorphous with very small amount of crystallinity. In the ribbon samples for different compositions we observed that the materials are essentially amorphous. In most cases, starting from an amorphous powder sample, the coatings are …

Characterization of HLW is a prerequisite for effective planning of HLW disposition and site closure performance assessment activities. Adequate characterization typically requires application of a combination of data sources, including process knowledge, theoretical relationships, and real-waste analytical data. Consistently obtaining high quality real-waste analytical data is a challenge, particularly for HLW sludge insolubles, due to the inherent complexities associated with matrix heterogeneities, sampling access limitations, radiological constraints, analyte loss mechanisms, and analyte measurement interferences. Understanding how each of these complexities affects the analytical results is the first step to developing a sampling and analysis program that provides characterization data that are both meaningful and adequate. A summary of the key elements impacting SRS HLW sludge analytical data uncertainties is presented in this paper, along with guidelines for managing each of the impacts. The particular elements addressed include: (a) sample representativeness; (b) solid/liquid phase quantification effectiveness; (c) solids dissolution effectiveness; (d) analyte cross contamination, loss, and tracking; (e) dilution requirements; (f) interference removal; (g) analyte measurement technique; and (h) analytical detection limit constraints. A primary goal of understanding these elements is to provide a basis for quantifying total propagated data uncertainty.

Nuclear Materials Management (NMM) of WSRC has recently installed the capability to perform both non-destructive and destructive examination of 3013 containers of Pu oxide in accordance with DOE-STD-3013. The containers will be opened and the oxide will be sampled for analysis. The remaining bulk oxide must then be safely stored in a non-3013-compliant configuration. Available processing equipment and controls cannot prevent the oxide from adsorbing moisture during this process. Subsequent radiolysis of moisture during storage may generate combustible quantities of gases while waiting final processing, and satisfying DOE Interim Safe Storage Criteria (ISSC) would require that storage containers be vented at impractical frequencies. With support from an independent National Laboratory, WSRC/NMM has demonstrated that a commercial hydrogen getter material will effectively prevent the accumulation of combustible gas concentrations. A project overview, including storage requirements and strategies, as well as getter technology, current test results, and anticipated future developments will be addressed.

Long-term sequestration of uranium at sites within the DOE complex is a significant problem that requires molecular-level information on the speciation, phase association, and spatial distribution of uranium

Retrieving ''suspect'' transuranic (TRU) waste from the Hanford Site's low-level waste burial grounds is a tall order, due to conditions that have changed as the work progresses. Project personnel developed several new methods for handling the waste that other retrieval operations may find useful. The Waste Retrieval Project is operated by Fluor Hanford, a prime contractor for the U.S. Department of Energy's Richland Operations Office since 1996.

The objective of this study was to determine detailed vertical, horizontal, intensive, and diel distributions of juvenile salmonid passage at the spillway at The Dalles Dam from April 12 to July16, 2006. These data are being applied in the Spillway Improvements Program to position release pipes for direct injury and mortality studies and to provide baseline data for assessment of the vortex suppression devices scheduled for deployment in 2007. We estimated fish distributions from hydroacoustic data collected with split-beam transducers arrayed across Bays 1 through 9 and 14. Spill at ~20 kcfs per bay was bulked at Bays 1-6, although the other bays were opened at times during the study to maintain a 40% spill percentage out of total project discharge. The vertical distribution of fish was skewed toward the surface during spring, but during summer, passage peaked at 2-3 m above the spillway ogee. Fish passage rates (number per hour) and fish densities (number per kcfs) were highest at Bay 6, followed by passage at Bay 5. This result comports with spillway horizontal distribution data from radio telemetry and hydroacoustic studies in 2004. The vertical and horizontal distribution of fish passage at bays 5 and 6 was much more …
