Reaching the Debt Limit: Background and Potential Effects on Government Operations (open access)

Reaching the Debt Limit: Background and Potential Effects on Government Operations

This report examines the possibility of the federal government reaching its statutory debt limit and not raising it, with a particular focus on government operations. First, the report explains the nature of the federal government's debt, the processes associated with federal borrowing, and historical events that may influence prospective actions. It also includes an analysis of what could happen if the federal government may no longer issue debt, has exhausted alternative sources of cash, and, therefore, depends on incoming receipts or other sources of funds to provide any cash needed to liquidate federal obligations.2 Finally, this report lays out considerations for increasing the debt limit under current policy and what impact fiscal policy could have on the debt limit going forward.

Children's Health Insurance: Information on Coverage of Services, Costs to Consumers, and Access to Care in CHIP and Other Sources of Insurance

A letter report issued by the Government Accountability Office with an abstract that begins "In five selected states, GAO determined that the separate State Children's Health Insurance Program (CHIP) plans were generally comparable to the benchmark plans selected by states in 2012 as models for the benefits that will be offered through qualified health plans (QHP) in 2014. The plans were comparable in the services they covered and the services on which they imposed limits, although there was some variation. For example, in coverage of hearing and outpatient therapy services, the benchmark plan in one of the five states--Kansas--did not cover hearing aids nor hearing tests, while the CHIP plans in all states covered at least one of these services. Similarly, two states' CHIP plans and three states' benchmark plans did not cover certain outpatient therapies--known as habilitative services--to help individuals attain or maintain skills they had not learned due to a disability. States' CHIP and benchmark state plans were also similar in terms of the services on which they imposed day, visit, or dollar limits. Plans most commonly imposed limits on outpatient therapies and pediatric dental, vision, and hearing services. Officials in all five states expect that CHIP coverage, …

Transportation Security Information Sharing: Stakeholders Generally Satisfied but TSA Could Improve Analysis, Awareness, and Accountability

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. transportation system, comprised of aviation, freight rail, highway, maritime, mass transit and passenger rail, and pipelines, moves billions of passengers and millions of tons of goods each year. Disrupted terrorist attacks involving rail and air cargo in 2010 demonstrate the importance of effective information sharing with transportation security stakeholders. The Transportation Security Administration (TSA) is the lead agency responsible for communicating security-related information with all modes. In response to the Implementing Recommendations of the 9/11 Commission Act of 2007, GAO assessed 1) the satisfaction of transportation stakeholders with the quality of TSA's transportation security information products, 2) satisfaction with mechanisms used to disseminate them, and 3) the extent to which TSA's roles and responsibilities are clearly defined. GAO surveyed 335 aviation, rail, and highway stakeholders (with an 82 percent response rate); reviewed agency planning documents; and interviewed industry associations, transportation stakeholders, and Department of Homeland Security officials. An electronic supplement to this report--GAO-12-67SP--provides survey results."

Private Pensions: Clarity of Required Reports and Disclosures Could Be Improved

A letter report issued by the Government Accountability Office with an abstract that begins "Sponsors of private sector pension plans are required to submit various reports to federal agencies and disclosures to participants depending on the plans' type, size, and circumstances. GAO identified more than 130 reports and disclosures stemming from provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA), and the Internal Revenue Code, as administered largely by three ERISA agencies: the Department of Labor (Labor), Internal Revenue Service (IRS), and Pension Benefit Guaranty Corporation (PBGC). Although each plan sponsor is required to submit only certain of these reports and disclosures, determining which ones can be challenging and the agencies' online resources to aid plan sponsors with this task are neither comprehensive nor up-to-date."

Development of tools and techniques for momentum compression of fast rare isotopes (open access)

Development of tools and techniques for momentum compression of fast rare isotopes

As part of our past research and development work, we have created and developed the LISE++ simulation code [Tar04, Tar08]. The LISE++ package was significantly extended with the addition of a Monte Carlo option that includes an option for calculating ion trajectories using a Taylor-series expansion up to fifth order, and implementation of the MOTER Monte Carlo code [Kow87] for ray tracing of the ions into the suite of LISE++ codes. The MOTER code was rewritten from FORTRAN into C++ and transported to the MS-Windows operating system. Extensive work went into the creation of a user-friendly interface for the code. An example of the graphical user interface created for the MOTER code is shown in the left panel of Figure 1 and the results of a typical calculation for the trajectories of particles that pass through the A1900 fragment separator are shown in the right panel. The MOTER code is presently included as part of the LISE++ package for downloading without restriction by the worldwide community. The LISE++ was extensively developed and generalized to apply to any projectile fragment separator during the early phase of this grant. In addition to the inclusion of the MOTER code, other important additions to …

Target Visualization at the National Ignition Facility (open access)

Target Visualization at the National Ignition Facility

As the National Ignition Facility continues its campaign to achieve ignition, new methods and tools will be required to measure the quality of the targets used to achieve this goal. Techniques have been developed to measure target surface features using a phase-shifting diffraction interferometer and Leica Microsystems confocal microscope. Using these techniques we are able to produce a detailed view of the shell surface, which in turn allows us to refine target manufacturing and cleaning processes. However, the volume of data produced limits the methods by which this data can be effectively viewed by a user. This paper introduces an image-based visualization system for data exploration of target shells at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. It aims to combine multiple image sets into a single visualization to provide a method of navigating the data in ways that are not possible with existing tools.

Solid Collection Efforts: Ta Collimator Evaluation (open access)

Solid Collection Efforts: Ta Collimator Evaluation

Ta collimator sets that were part of the gated x-ray detector diagnostic (GXD) at NIF were analyzed for debris distribution and damage in 2011. These disks (ranging in thickness from 250 to 750 {mu}m) were fielded approximately 10 cm from target chamber center (TCC) on various symcap, THD and re-emit shots. The nose cone holder and forward Ta collimator (facing target chamber center, TCC) from all shots show evidence of surface melt. Non-destructive analysis techniques such as optical microscopy, surface profilometry, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and x-ray fluorescence (XRF) were used to determine debris composition and degree of deformation associated with each Ta disk. Molten debris from the stainless steel nose cone contaminated the surface of the collimators along with other debris associated with the target assembly (Al, Si, Cu, Au and In). Surface elemental analysis of the forward collimator Ta disks indicates that Au hohlraum debris is less concentrated on these samples versus those fielded 50 cm from TCC in the wedge range filter (WRF) assembly. It is possible that the Au is distributed below or within the stainless steel melt layer covering the disk, as most of the foreign debris is captured in the …

GROUNDWATER MONITORING REPORT GENERATION TOOLS - 12005 (open access)

GROUNDWATER MONITORING REPORT GENERATION TOOLS - 12005

Compliance with National and State environmental regulations (e.g. Resource Conservation and Recovery Act (RCRA) and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) aka SuperFund) requires Savannah River Site (SRS) to extensively collect and report groundwater monitoring data, with potential fines for missed reporting deadlines. Several utilities have been developed at SRS to facilitate production of the regulatory reports which include maps, data tables, charts and statistics. Components of each report are generated in accordance with complex sets of regulatory requirements specific to each site monitored. SRS developed a relational database to incorporate the detailed reporting rules with the groundwater data, and created a set of automation tools to interface with the information and generate the report components. These process improvements enhanced quality and consistency by centralizing the information, and have reduced manpower and production time through automated efficiencies.

Summary of Blast Shield and Material Testing for Development of Solid Debris Collection at the National Ignition Facility (NIF) (open access)

Summary of Blast Shield and Material Testing for Development of Solid Debris Collection at the National Ignition Facility (NIF)

The ability to collect solid debris from the target chamber following a NIF shot has application for both capsule diagnostics, particularly for fuel-ablator mix, and measuring cross sections relevant to the Stockpile Stewardship program and nuclear astrophysics. Simulations have shown that doping the capsule with up to 10{sup 15} atoms of an impurity not otherwise found in the capsule does not affect its performance. The dopant is an element that will undergo nuclear activations during the NIF implosion, forming radioactive species that can be collected and measured after extraction from the target chamber. For diagnostics, deuteron or alpha induced reactions can be used to probe the fuel-ablator mix. For measuring neutron cross sections, the dopant should be something that is sensitive to the 14 MeV neutrons produced through the fusion of deuterium and tritium. Developing the collector is a challenge due to the extreme environment of the NIF chamber. The collector surface is exposed to a large photon flux from x-rays and unconverted laser light before it is exposed to a debris wind that is formed from vaporized material from the target chamber center. The photons will ablate the collector surface to some extent, possibly impeding the debris from reaching …

Scrape-Off-Layer Flow Studies in Tokamaks: Final Report of LDRD Project 09-ERD-025

A summary is given of the work carried out under the LDRD project 09-ERD-025 entitled Scrape-Off-Layer Flow Studies in Tokamaks. This project has lead to implementation of the new prototype Fourier Transform Spectrometer edge plasma flow diagnostic on the DIII-D National Fusion Facility at General Atomics, acquisition of carbon impurity concentration and flow data, and demonstration that the resulting data compare reasonably well with LLNL's edge plasma transport code UEDGE. Details of the work are contained in attached published papers, while the most recent results that are being written-up for publication are summarized in the report. Boundary plasma flows in tokamak fusion devices are key in determining the distribution of fuel and impurity ions, with tritium build-up in the walls an especially critical operational issue. The intrusion of impurity ions to the hot plasma core region can result in serious energy-loss owing to line radiation. However, flow diagnostic capability has been severely limited in fusion-relevant hot edge plasmas where Langmuir-type probes cannot withstand the high heat flux and traditional Doppler spectroscopy has limited resolution and signal strength. Thus, new edge plasma flow diagnostic capabilities need to be developed that can be used in existing and future devices such as ITER. …

Scientific/Technical Report

This symposium aimed to bring together researchers working on quantifying nanoscale carrier transport processes in excitonic solar cells. Excitonic solar cells, including all-organic, hybrid organic-inorganic and dye-sensitized solar cells (DSSCs), offer strong potential for inexpensive and large-area solar energy conversion. Unlike traditional inorganic semiconductor solar cells, where all the charge generation and collection processes are well understood, these excitonic solar cells contain extremely disordered structures with complex interfaces which results in large variations in nanoscale electronic properties and has a strong influence on carrier generation, transport, dissociation and collection. Detailed understanding of these processes is important for fabrication of highly efficient solar cells. Efforts to improve efficiency are underway at a large number of research groups throughout the world focused on inorganic and organic semiconductors, photonics, photophysics, charge transport, nanoscience, ultrafast spectroscopy, photonics, semiconductor processing, device physics, device structures, interface structure etc. Rapid progress in this multidisciplinary area requires strong synergetic efforts among researchers from diverse backgrounds. Such efforts can lead to novel methods for development of new materials with improved photon harvesting and interfacial treatments for improved carrier transport, process optimization to yield ordered nanoscale morphologies with well-defined electronic structures.
