Testimony issued by the Government Accountability Office with an abstract that begins "The federal government plays a wide-ranging role in promoting financial literacy. Efforts to improve financial literacy in the United States involve an array of public, nonprofit, and private participants, but among those participants, the federal government is distinctive for its size and reach and for the diversity of its components, which address a wide range of issues and populations. At forums of financial literacy experts that GAO held in 2004 and 2011, participants noted that the federal government can use its “bully pulpit,” convening power, and other tools to draw attention to the issue, and serve as an objective and unbiased source of information about the selection of financial products and services. In prior work, GAO cited a 2009 report by the RAND Corporation in which 20 federal agencies self-identified as having 56 federal financial literacy programs, but GAO’s subsequent analysis found substantial inconsistency in how different agencies defined and counted financial literacy programs. Based on a more consistent set of criteria, GAO identified 16 significant financial literacy programs or activities among 14 federal agencies, as well as 4 housing counseling programs among 3 federally supported entities, in …

A letter report issued by the Government Accountability Office with an abstract that begins "The F-22A and legacy modernization programs GAO reviewed were rooted in different development strategies. The F-22A began as a single-step program and did not anticipate the need for future modernization, while the legacy programs each began with the expectation that their aircraft would be incrementally upgraded over time. F-22A modernization began in reaction to a major shift in the aircraft’s basic mission, which required the development of new capabilities that had not been planned for as part of the initial development program. In contrast, the legacy modernization programs made planned incremental improvements to existing mission capabilities. All of the modernization programs began at about the same time in development and procurement. The F-22A program is developing and retrofitting new capabilities onto a complex stealth aircraft, which is costly—currently estimated at $9.7 billion total. Legacy modernization programs were less complex, and thus less costly, and incorporated mature technologies onto new production aircraft. Accurately identifying and comparing the total cost of each modernization program is difficult. Each of the programs, including the F-22A, initially managed and funded modernization as a continuation of its baseline program, so modernization costs …

A letter report issued by the Government Accountability Office with an abstract that begins "The Office of Management and Budget (OMB) and key federal agencies have made progress on action items in the Information Technology (IT) Reform Plan, but there are several areas where more remains to be done. Of the 10 key action items GAO reviewed, 3 were completed and 7 were partially completed by December 2011, in part because the initiatives are complex. OMB reported greater progress than GAO determined, stating that 7 of the 10 action items were completed and that 3 were partially completed. While OMB officials acknowledge that there is more to do in each of the topic areas, they consider the key action items to be completed because the IT Reform Plan has served its purpose as a catalyst for a set of broader initiatives. They explained that work will continue on all of the initiatives even after OMB declares that the related action items are completed under the IT Reform Plan. We disagree with this approach. In prematurely declaring the action items to be completed, OMB risks losing momentum on the progress it has made to date. Until OMB and the agencies complete …

Correspondence issued by the Government Accountability Office with an abstract that begins "The policies and procedures of the CDFI and NMTC Programs help ensure that awards and allocations generally are proportionate to the numbers of qualified applicants that serve metropolitan and nonmetropolitan areas. The CDFI Program’s authorizing legislation and regulations require that award recipients constitute a geographically diverse group, serving metropolitan and nonmetropolitan areas and Native communities from different U.S. regions. To meet this requirement, CDFI Program officials have used the application review process and established a goal of matching the proportion of awards to the proportion of qualified applicants that primarily serve nonmetropolitan areas. This proportion changed from year to year depending on the number of qualified applicants that served nonmetropolitan areas. According to officials, revisions to the award procedures in the fiscal year 2012 funding round will enhance the CDFI Program’s ability to achieve proportionality. In 2006, Congress, in the Tax Relief and Health Care Act of 2006, added a requirement for the NMTC Program that nonmetropolitan counties receive a proportional allocation of qualified equity investments. To meet this requirement, in 2008, the NMTC Program implemented two goals in its application review process. The first goal requires that …

A letter report issued by the Government Accountability Office with an abstract that begins "Over the years, the federal-aid highway program has expanded to encompass broader goals, more responsibilities, and a variety of approaches. As the program grew more complex, the Federal Highway Administration’s (FHWA) oversight role also expanded, while its resources have not kept pace. As GAO has reported, this growth occurred without a well-defined overall vision of evident national interests and the federal role in achieving them. GAO has recommended Congress consider restructuring federal surface transportation programs, and for this and other reasons, funding surface transportation remains on GAO’s high-risk list."

A letter report issued by the Government Accountability Office with an abstract that begins "The Nuclear Regulatory Commission (NRC) and companies licensed to operate nuclear power reactors (or licensees) apply probabilistic risk assessment (PRA) to natural hazards at operating U.S. nuclear reactors to a limited extent. When the 104 operating reactors were originally licensed before 1997, NRC required licensees to assess natural hazards using deterministic analysis, which—informed by historical experience, test results, and expert judgment—considers a specific set of potential accidents and how the consequences of those accidents can be prevented and mitigated. Subsequent to most of these initial licenses being issued, NRC, through policy statements and other documents, has endorsed PRA—a systematic method for assessing what can go wrong, its likelihood, and its consequences, resulting in quantitative estimates of risk—as a means to enhance and extend traditional deterministic analysis. In 1991, NRC requested that licensees voluntarily examine their reactors’ vulnerability to natural hazards and suggested PRA as one of several possible methods for licensees to use in their examinations. However, most licensees opted to use other methods. According to NRC officials and nuclear power industry representatives—and reflected in data GAO obtained from five licensees that together operate 25 reactors—few …

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Emergency Management Agency (FEMA) is taking steps to integrate its workforce planning and training efforts across the agency consistent with critical success factors for strategic human capital management such as initiating working groups to coordinate related activities, but its efforts are in the early stages. Until recently FEMA’s efforts related to workforce planning have been independently conducted by various offices across the agency. In January 2012, FEMA human capital officials reported that they began integrating agencywide workforce planning initiatives underway by other program offices, such as FEMA’s Qualification System, which was developed to establish qualification requirements for FEMA’s workforce for deployment purposes, among other things. Additionally, FEMA’s Human Capital Office plans to release a directive that, according to officials, will address the need for integrating the agency’s training efforts consistent with critical success factors for strategic human capital management. Having integrated workforce planning and training could help FEMA ensure that it has the properly sized and skilled workforce to effectively meet its mission. However, the effectiveness of these integration efforts is dependent upon FEMA following through with its plans and it is, therefore, too …

A letter report issued by the Government Accountability Office with an abstract that begins "The National Nuclear Security Administration (NNSA) and its M&O contractors have developed and implemented multifaceted strategies to recruit, develop, and retain both the federal and contractor workforces needed to preserve critical skills in the enterprise. NNSA’s recruiting and retention efforts for its federal staff focus on attracting early career hires with competitive pay and development opportunities. Its development efforts generally rely on two key programs to develop its critically skilled workforce––one that identifies needs and another that identifies the qualifications necessary to meet them. For strategic planning purposes, NNSA is also undertaking a comprehensive reassessment and analysis of staffing requirements to ascertain future federal workforce requirements. M&O contractors’ recruitment and retention strategies vary from site to site, but each site focuses on maintaining competitive compensation packages. Their development efforts vary in approach and scope and face some challenges––particularly in preserving underground nuclear testing skills."

Testimony issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service (IRS) has made improvements in processing tax returns, and electronic filing (e-filing), which provides benefits to taxpayers including faster refunds, continues to increase. However, IRS’s performance in providing service over the phone and responding to paper correspondence has declined in recent years. For 2012, as with previous years, IRS officials attribute the lower performance to other funding priorities."

A letter report issued by the Government Accountability Office with an abstract that begins "The Social Security Administration (SSA) has undertaken numerous modernization efforts, but it lacks effective measurement tools to determine progress. Since 2001, SSA has reported spending about $5 billion on the modernization of its systems. Specifically, the agency has undertaken hundreds of modernization projects each year from 2001 to 2011, and officials identified 120 such initiatives that they considered to be key investments in modernization. About two-thirds of these projects were for modernizing and enhancing existing systems, while other efforts were aimed at moving from manual to electronic processes and online access, and the development of new or redesigned system software. These efforts also enhanced work processes, automated notices to beneficiaries, and modified systems to accommodate legislation, among other things. Nonetheless, SSA still has major efforts under way to transition from its aging systems to a more modernized IT environment. Specifically, in order to help meet the agency’s key strategic goal of strengthening its infrastructure and further enhancing its online services, SSA intends to streamline its operations and reduce duplication in databases to allow for more efficient maintenance. The agency also intends to complete its conversion to …

Conventional storage of large amounts of hydrogen in its molecular form is difficult and expensive because it requires employing either extremely high pressure gas or very low temperature liquid. Because of the importance of hydrogen as a fuel, the DOE has set system targets for hydrogen storage of gravimetric (5.5 wt%) and volumetric (40 g L-1) densities to be achieved by 2015. Given that these are system goals, a practical material will need to have higher capacity when the weight of the tank and associated cooling or regeneration system is considered. The size and weight of these components will vary substantially depending on whether the material operates by a chemisorption or physisorption mechanism. In the latter case, metal-organic frameworks (MOFs) have recently been identified as promising adsorbents for hydrogen storage, although little data is available for their sorption behavior. This grant was focused on the study of MOFs with these specific objectives. (1) To examine the effects of functionalization, catenation, and variation of the metal oxide and organic linkers on the low-pressure hydrogen adsorption properties of MOFs. (2) To develop a strategy for producing MOFs with high surface area and porosity to reduce the dead space and increase the hydrogen …

Black hole (BH) accretion flows and jets are qualitatively affected by the presence of ordered magnetic fields. We study fully three-dimensional global general relativistic magnetohydrodynamic (MHD) simulations of radially extended and thick (height H to cylindrical radius R ratio of |H/R| {approx} 0.2-1) accretion flows around BHs with various dimensionless spins (a/M, with BH mass M) and with initially toroidally-dominated ({phi}-directed) and poloidally-dominated (R-z directed) magnetic fields. Firstly, for toroidal field models and BHs with high enough |a/M|, coherent large-scale (i.e. >> H) dipolar poloidal magnetic flux patches emerge, thread the BH, and generate transient relativistic jets. Secondly, for poloidal field models, poloidal magnetic flux readily accretes through the disk from large radii and builds-up to a natural saturation point near the BH. While models with |H/R| {approx} 1 and |a/M| {le} 0.5 do not launch jets due to quenching by mass infall, for sufficiently high |a/M| or low |H/R| the polar magnetic field compresses the inflow into a geometrically thin highly non-axisymmetric 'magnetically choked accretion flow' (MCAF) within which the standard linear magneto-rotational instability is suppressed. The condition of a highly-magnetized state over most of the horizon is optimal for the Blandford-Znajek mechanism that generates persistent relativistic jets with …

Large Scale Integrated Testing (LSIT) is being planned by Bechtel National, Inc. to address uncertainties in the full scale mixing performance of the Hanford Waste Treatment and Immobilization Plant (WTP). Testing will use simulated waste rather than actual Hanford waste. Therefore, the use of suitable simulants is critical to achieving the goals of the test program. External review boards have raised questions regarding the overall representativeness of simulants used in previous mixing tests. Accordingly, WTP requested the Savannah River National Laboratory (SRNL) to assist with development of simulants for use in LSIT. Among the first tasks assigned to SRNL was to develop a list of waste properties that matter to pulse-jet mixer (PJM) mixing of WTP tanks. This report satisfies Commitment 5.2.3.1 of the Department of Energy Implementation Plan for Defense Nuclear Facilities Safety Board Recommendation 2010-2: physical properties important to mixing and scaling. In support of waste simulant development, the following two objectives are the focus of this report: (1) Assess physical and chemical properties important to the testing and development of mixing scaling relationships; (2) Identify the governing properties and associated ranges for LSIT to achieve the Newtonian and non-Newtonian test objectives. This includes the properties to support …

This report covers the scientific progress and results made in the development of high efficiency multijunction solar cells and the light concentrating non-imaging optics for the commercial generation of renewable solar energy. During the contract period the efficiency of the multijunction solar cell was raised from 36.5% to 40% in commercially available fully qualified cells. In addition significant strides were made in automating production process for these cells in order to meet the costs required to compete with commercial electricity. Concurrent with the cells effort Boeing also developed a non imaging optical systems to raise the light intensity at the photovoltaic cell to the rage of 800 to 900 suns. Solar module efficiencies greater than 30% were consistently demonstrated. The technology and its manufacturing were maturated to a projected price of < $0.015 per kWh and demonstrated by automated assembly in a robotic factory with a throughput of 2 MWh/yr. The technology was demonstrated in a 100 kW power plant erected at California State University Northridge, CA.

Spectroscopy provides valuable information about the temperature and density of a compressed pellet in a plasma. Elliptically curved pentaerythritol (PET) crystals are used as components for spectrometers. Their elliptical geometry gives several advantages related to spectral energy range, source focus, and spectral image compression.[1] The crystal curvature increases the spectrometer throughput but at the cost of a loss in resolution. Four different crystals are used in a spectrometer at the National Ignition Facility (NIF) target chamber at Lawrence Livermore National Laboratory (LLNL). Figure 1 shows the arrangement of the elliptical PET crystals in the snout of a NIF target diagnostic shown in Figure 2. The spectrum from the crystals is captured by four image plates located behind the crystals. A typical mandrel, the darkened section, upon which the PET crystal is glued, is shown in Figure 3, which also shows the complete ellipse. There are four elliptical segment types, each having the same major axis but a different minor axis. The crystals are 150 mm long in the diffraction direction and 25.4 mm high. Two crystals of each type were calibrated. The throughput for each spectrometer is determined by the integrated reflectivity of the PET crystal.[1] The goal of this …

This report summarizes a study into some false positive issues in the use of radioxenon as a method to verify a clandestine nuclear weapons explosion. False positives arise due to similarities between the radioxenon signature generated in medical isotope production and that generated in a nuclear weapon explosion. This report also discusses how to categorize the radioxenon by levels of urgency for manual analysis and interpretation and recommends applying machine learning and time series analysis techniques in the automation of radioxenon characterization. The literature indicates that medical isotope production is a major contributor to atmospheric radioxenon and is the main source of confusion in determining the source of radioxenon. While radioxenon emissions from nuclear power plants can be distinguished from that from nuclear weapon explosions, emissions from medical isotope production generate signatures similar to certain nuclide ratios found in nuclear weapons explosions. Different techniques for analyzing nuclide concentrations and ratios as well as including other sensing modalities via sensor fusion are discussed.

This includes development of the approach and performing appropriate demonstration in the lab; (2) Develop methods to predict composite strength reduction due to defects; and (3) Develop process models to predict defects from leading indicators found in the uncured composites.

The objective of this project is to investigate and develop novel, mechanically activated, nanoscale Li3N-based and LiBH4-based materials that are able to store and release {approx}10 wt% hydrogen at temperatures near 100 C with a plateau hydrogen pressure of less than 10 bar. Four (4) material systems have been investigated in the course of this project in order to achieve the project objective. These 4 systems are (i) LiNH2+LiH, (ii) LiNH2+MgH2, (iii) LiBH4, and (iv) LiBH4+MgH2. The key findings we have obtained from these 4 systems are summarized below. *The thermodynamic driving forces for LiNH2+LiH and LiBH4 systems are not adequate to enable H2 release at temperatures &lt; 100 C. *Hydrogen release in the solid state for all of the four systems is controlled by diffusion, and thus is a slow process. *LiNH2+MgH2 and LiBH4+MgH2 systems, although possessing proper thermodynamic driving forces to allow for H2 release at temperatures &lt; 100 C, have sluggish reaction kinetics because of their diffusion-controlled rate-limiting steps. *Reducing particles to the nanometer length scale (&lt; 50 nm) can improve the thermodynamic driving force to enable H2 release at near ambient temperature, while simultaneously enhancing the reaction kinetics as well as changing the diffusion-controlled rate-limiting step …

It has been widely recognized that the energy saving benefits of GSHP systems are best realized in the northern and central regions where heating needs are dominant or both heating and cooling loads are comparable. For hot and humid climate such as in the states of FL, LA, TX, southern AL, MS, GA, NC and SC, buildings have much larger cooling needs than heating needs. The Hybrid GSHP (HGSHP) systems therefore have been developed and installed in some locations of those states, which use additional heat sinks (such as cooling tower, domestic water heating systems) to reject excess heat. Despite the development of HGSHP the comprehensive analysis of their benefits and barriers for wide application has been limited and often yields non-conclusive results. In general, GSHP/HGSHP systems often have higher initial costs than conventional systems making short-term economics unattractive. Addressing these technical and financial barriers call for additional evaluation of innovative utility programs, incentives and delivery approaches. From scientific and technical point of view, the potential for wide applications of GSHP especially HGSHP in hot and humid climate is significant, especially towards building zero energy homes where the combined energy efficient GSHP and abundant solar energy production in hot climate …
