A letter report issued by the Government Accountability Office with an abstract that begins "Neutron detectors are used to detect neutron radiation in science, security, and other applications. For example, large-area detectors detect neutrons at science facilities across the world and radiation portal monitors screen vehicles and cargo at ports and border crossings for nuclear material that terrorists could use in a nuclear weapon. Helium-3 is a critical component of such neutron detectors, and in 2008 the U.S. government became aware of a severe shortage of helium-3 gas. While demand for it has increased, helium-3 is currently produced as a byproduct of the radioactive decay of tritium, and the United States ceased tritium production in 1988. The shortage has led science facilities and federal agencies such as the DOD and DHS to identify or develop alternative detector technologies. GAO was asked to review the effectiveness of alternative neutron detector technologies that do not use helium-3. GAO assessed (1) what alternative neutron detectors are currently available and their effectiveness, and (2) the status of research on alternative neutron detector technologies under development for future availability. GAO reviewed agency documents and interviewed agency officials and detector developers. With assistance from the National …

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government invests heavily in information technology (IT). In recent years, the Office of Management and Budget (OMB) has made efforts to improve the transparency, oversight, and management of the federal government's IT investments. More recently, in June 2009, OMB deployed the IT Dashboard, a Web-based system that provides detailed performance information on federal IT investments. GAO was asked to (1) describe the current number and types of IT investments reported by federal agencies on the IT Dashboard, (2) evaluate the adequacy of OMB's guidance to federal agencies in reporting on IT investments, and (3) evaluate efforts to identify and address potentially duplicative investments. To address these objectives, GAO analyzed data from the IT Dashboard, analyzed 10 federal agencies' investment guidance and reports, and interviewed agency officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Veterans Affairs (VA) has struggled to provide timely reviews for veterans who appeal decisions on their disability compensation claims. A veteran appeals to the VA regional office that made the initial decision, and if still dissatisfied, to the Board of Veterans Appeals (Board). An appeal to the Board adds more than 2 years, on average, to the wait for a decision on the appeal. To resolve more appeals at the regional level and avoid waits at the Board, VA, in 2001, established the Decision Review Officer (DRO) review as an alternative to the traditional regional office appeal review. A DRO is given authority to grant additional benefits after reviewing an appeal based on a difference of opinion with the original decision. In contrast, under the traditional review, new evidence is generally required for a grant of additional benefits. GAO examined (1) the extent to which veterans choose a DRO review, (2) outcomes for DRO reviews, and (3) VA's challenges in managing DROs. GAO analyzed Board data, surveyed managers in all 57 regional offices, visited 4 offices, and interviewed veterans."

Correspondence issued by the Government Accountability Office with an abstract that begins "In fiscal year 2010, about 80 percent of the U.S. Department of Agriculture's (USDA) total outlays of about $129 billion was used to fund mandatory spending programs--programs with at least some spending that is controlled through eligibility rules, benefit formulas, and other parameters that are set in law other than appropriations acts. At USDA, mandatory spending programs include the majority of the department's nutrition assistance, farm commodity, crop insurance, and export promotion programs, as well as a number of its conservation programs. A May 23, 2005, memorandum from the Director of Office of Management and Budget (OMB) to the heads of departments and agencies provided guidance on a new OMB review process that would apply to administrative actions not required by law that would increase mandatory spending. As directed by the memorandum, in submitting to OMB for review such proposed actions, agencies must include one or more proposals for other administrative actions to be taken by the agency that would comparably reduce mandatory spending. This process for controlling spending is referred to as "administrative pay-as-you-go (PAYGO)." Administrative actions subject to administrative PAYGO include regulations, demonstrations, program notices, guidance …

A publication issued by the Government Accountability Office with an abstract that begins "As of March 2011, the Army had over $4 billion worth of nonstandard equipment in Iraq--that is equipment not included on units' standard list of authorized equipment. Concurrently, the Department of Defense (DOD) has acquired over $44 billion worth of Mine Resistant Ambush Protected vehicles (MRAP), most of which have been allocated to the Army. This equipment must be withdrawn from Iraq by December 31, 2011. GAO examined the extent to which the Army has plans and processes for the disposition of (1) nontactical nonstandard equipment; (2) tactical nonstandard equipment; and (3) MRAPs that are no longer needed in Iraq. In performing this review, GAO analyzed relevant documents, interviewed Army officials, and visited Sierra Army Depot, where most nontactical nonstandard equipment is shipped once it leaves Iraq."

A letter report issued by the Government Accountability Office with an abstract that begins "Recognizing the potential of increased exports to drive economic growth and create jobs, President Obama in 2010 launched the National Export Initiative (NEI), aimed at doubling the dollar value of U.S. exports by the end of 2014. As requested, GAO examined the extent to which (1) the goals and activities of the U.S. and Foreign Commercial Service (CS) support the NEI, (2) CS performance measures accurately reflect its activities and align with the NEI, and (3) CS incorporates relevant data in allocating resources to help achieve its strategic goals. GAO interviewed Department of Commerce (Commerce) officials, particularly from CS, and CS staff and officials at six overseas posts. GAO analyzed the NEI's priorities, and documents and data related to CS activities and performance."

A publication issued by the Government Accountability Office with an abstract that begins "Over 3,600 people in this country died in 2009 as a result of crashes involving large commercial trucks and buses. Until recently the Federal Motor Carrier Safety Administration (FMCSA) and its state partners tracked the safety of motor carriers--companies that own these vehicles--by conducting resource-intensive compliance reviews of a small percentage of carriers. In 2004, FMCSA began its Compliance, Safety, and Accountability (CSA) program. CSA is intended to identify and evaluate carriers and drivers posing high safety risks. FMCSA has focused on three key CSA oversight activities to evaluate carriers: a new Safety Measurement System (SMS) using more roadside inspection and other data to identify at-risk carriers; a wider range of "interventions" to reach more at-risk carriers; and using SMS data to suspend unfit carriers. FMCSA expected to fully implement CSA by late 2010. FMCSA also plans to separately use data to rate drivers' fitness. In this report, GAO assessed: (1) the status of the CSA rollout and issues that could affect it and (2) CSA's potential to improve safety. GAO reviewed CSA plans and data, visited eight states, and interviewed FMCSA, state, and industry officials."

The Department of Homeland Security (DHS) has statutory authority to regulate chemical facilities for security purposes. This report provides a brief overview of the existing statutory authority and the regulation implementing this authority. It describes several policy issues raised in previous debates regarding chemical facility security and identifies policy options for congressional consideration. Finally, the report discusses legislation in the Congress regarding whether funding should be continued to fund these efforts.

Savannah River National Laboratory (SRNL) periodically analyses solvent samples from Modular Caustic-Side Solvent Extraction Unit (MCU) in support of continuing operations. A quarterly analysis of the solvent is required to maintain solvent composition within specifications. Analytical results of the analyses of Solvent Hold Tank (SHT) samples MCU-11-314, MCU-11-315, MCU-11-316, MCU-11-317, MCU-11-318 and MCU-11-319 have been previously reported. MCU has experienced a modest decline in cesium removal efficiency while processing the current feed, 'Macrobatch 3'. While the target decontamination factor (DF) is 200, the fiscal year 2011 DF average is 161. The results of the prior solvent analysis report did not identify a specific factor that would correlate with the poor cesium decontamination beyond a low concentration of the suppressor, trioctylamine. New analyses of the quarterly sample are reported in this document, as well as a cross-check of {sup 137}Cs measurements for SRNL and F/H lab. Furthermore, in an attempt to discover the reason for the decline in DF at MCU, SRNL was tasked with analyzing numerous Caustic Wash Tank (CWT) and chemical feed samples.

Quantum dots have been used as bright fluorescent tags with high photostability to probe numerous biological systems. In this work we present the tetrapod quantum dot as a dynamic, next-generation nanocrystal probe that fluorescently reports cellular forces with spatial and temporal resolution. Its small size and colloidal state suggest that the tetrapod may be further developed as a tool to measure cellular forces in vivo and with macromolecular spatial resolution.

The purpose of the project described in this report is to identify and document the commercial and emerging (projected to be commercialized within the next 3 years) hydrogen and fuel cell technologies and products that resulted from Department of Energy support through the Fuel Cell Technologies (FCT) Program in the Office of Energy Efficiency and Renewable Energy (EERE). To do this, Pacific Northwest National Laboratory (PNNL) undertook two efforts simultaneously to accomplish this project. The first effort was a patent search and analysis to identify hydrogen- and fuel-cell-related patents that are associated with FCT-funded projects (or projects conducted by DOE-EERE predecessor programs) and to ascertain the patents current status, as well as any commercial products that may have used the technology documented in the patent. The second effort was a series of interviews with current and past FCT personnel, a review of relevant program annual reports, and an examination of hydrogen- and fuel-cell-related grants made under the Small Business Innovation Research and Small Business Technology Transfer Programs, and within the FCT portfolio.

Pacific Northwest National Laboratory was contracted by Washington River Protection Solutions, LLC to provide the technical basis for estimating radionuclide release from the engineered portion of the disposal facility (e.g., source term). Vitrifying the low-activity waste at Hanford is expected to generate over 1.6 x 10{sup 5} m{sup 3} of glass (Certa and Wells 2010). The volume of immobilized low-activity waste (ILAW) at Hanford is the largest in the DOE complex and is one of the largest inventories (approximately 8.9 x 10{sup 14} Bq total activity) of long-lived radionuclides, principally {sup 99}Tc (t{sub 1/2} = 2.1 x 10{sup 5}), planned for disposal in a low-level waste (LLW) facility. Before the ILAW can be disposed, DOE must conduct a performance assessment (PA) for the Integrated Disposal Facility (IDF) that describes the long-term impacts of the disposal facility on public health and environmental resources. As part of the ILAW glass testing program PNNL is implementing a strategy, consisting of experimentation and modeling, in order to provide the technical basis for estimating radionuclide release from the glass waste form in support of future IDF PAs. The purpose of this report is to summarize the progress made in fiscal year (FY) 2011 toward implementing …

This Closure Report (CR) presents information supporting closure of Corrective Action Unit (CAU) 116, Area 25 Test Cell C Facility. This CR complies with the requirements of the Federal Facility Agreement and Consent Order (FFACO) that was agreed to by the State of Nevada; the U.S. Department of Energy (DOE), Environmental Management; the U.S. Department of Defense; and DOE, Legacy Management (FFACO, 1996 [as amended March 2010]).

Site characterization data and process knowledge indicated that surface areas were radiologically …

Unified Parallel C (UPC) extends the C programming language (ISO C 99) with explicit parallel programming support for the partitioned global address space (PGAS), which provides a global memory space with localized partitions to each thread. Like its ancestor C, UPC is a low-level language that emphasizes code efficiency over safety. The absence of dynamic (and static) safety checks allows programmer oversights and software flaws that can be hard to spot. In this paper, we present an extension of a dynamic analysis tool, ROSE-Code Instrumentation and Runtime Monitor (ROSECIRM), for UPC to help programmers find C-style errors involving the global address space. Built on top of the ROSE source-to-source compiler infrastructure, the tool instruments source files with code that monitors operations and keeps track of changes to the system state. The resulting code is linked to a runtime monitor that observes the program execution and finds software defects. We describe the extensions to ROSE-CIRM that were necessary to support UPC. We discuss complications that arise from parallel code and our solutions. We test ROSE-CIRM against a runtime error detection test suite, and present performance results obtained from running error-free codes. ROSE-CIRM is released as part of the ROSE compiler under …
