A letter report issued by the Government Accountability Office with an abstract that begins "In 2007, the United States enacted a law incrementally raising the minimum wages in American Samoa and the Commonwealth of the Northern Mariana Islands (CNMI) until they equal the U.S. minimum wage. American Samoa's minimum wage increased by $.50 three times, and the CNMI's four times before legislation delayed the increases, providing for no increase in American Samoa in 2010 or 2011 and none in the CNMI in 2011. As scheduled, American Samoa's minimum wage will equal the current U.S. minimum wage of $7.25 in 2018, and the CNMI's will reach it in 2016. Recent economic declines in both areas reflect the closure of one of two tuna canneries in American Samoa and the departure of the garment industry in the CNMI. GAO is required to report in 2010, 2011, 2013, and biennially thereafter on the impact of the minimum wage increases. This report updates GAO's 2010 report and describes, since the increases began, (1) employment and earnings, and (2) the status of key industries. GAO reviewed federal and local information; collected data from employers through a questionnaire and from employers and workers through discussion groups; …

Aqueous radioactive wastes from Savannah River Site (SRS) separations and vitrification processes are contained in large underground carbon steel tanks. Inspections made during 2010 to evaluate these vessels and other waste handling facilities along with evaluations based on data from previous inspections are the subject of this report. The 2010 inspection program revealed that the structural integrity and waste confinement capability of the Savannah River Site waste tanks were maintained. All inspections scheduled per SRR-LWE-2009-00138, HLW Tank Farm Inspection Plan for 2010, were completed. Ultrasonic measurements (UT) performed in 2010 met the requirements of C-ESG-00006, In-Service Inspection Program for High Level Waste Tanks, Rev. 3, and WSRC-TR-2002-00061, Rev.6. UT inspections were performed on Tanks 30, 31 and 32 and the findings are documented in SRNL-STI-2010-00533, Tank Inspection NDE Results for Fiscal Year 2010, Waste Tanks 30, 31 and 32.

A letter report issued by the Government Accountability Office with an abstract that begins "Asbestos litigation arose out of millions of Americans' lengthy occupational exposure to asbestos which is linked to malignant and nonmalignant diseases. To date, about 100 companies have declared bankruptcy at least partially due to asbestos-related liability. In accordance with Chapter 11 and 524(g) of the federal bankruptcy code, a company may transfer its liabilities and certain assets to an asbestos personal injury trust, which is then responsible for compensating present and future claimants. Since 1988, 60 trusts have been established to pay claims with about $37 billion in total assets. GAO was asked to examine asbestos trusts set up pursuant to 524(g). This report addresses: (1) How much asbestos trusts have paid in claims and how trusts are administered, (2) How trust claim and payment information is made available to outside parties, and (3) Stakeholder--plaintiff and defense attorneys, trust officials, and other interested parties--views on whether more trust and claimant information should be made available to outside parties and efforts to change the trust system and processes. GAO analyzed trust agreements for 44 of 60 trusts and trust distribution procedures for 52 of 60 trusts, as …

A letter report issued by the Government Accountability Office with an abstract that begins "More than 300 insured depository institutions have failed since the current financial crisis began in 2007, at an estimated cost of almost $60 billion to the deposit insurance fund (DIF), which covers losses to insured depositors. Since 1991, Congress has required federal banking regulators to take prompt corrective action (PCA) to identify and promptly address capital deficiencies at institutions to minimize losses to the DIF. The Dodd-Frank Wall Street Reform and Consumer Protection Act requires GAO to study federal regulators' use of PCA. This report examines (1) the outcomes of regulators' use of PCA on the DIF; (2) the extent to which regulatory actions, PCA thresholds, and other financial indicators help regulators address likely bank trouble or failure; and (3) options available to make PCA a more effective tool. GAO analyzed agency and financial data to describe PCA and DIF trends and assess the timeliness of regulator actions and financial indicators. GAO also reviewed relevant literature and surveyed expert stakeholders from research, industry, and regulatory sectors on options to improve PCA."

This report discusses the gold standard, Basically Silver:1792-1834, Basically Gold: 1834-1862, Fiat Paper Money: 1862-1879, A true gold standard: 1879-1933, and Cutting the Links to gold: 1967-1973.

When streams of rapidly moving flow merge in a T-junction, the potential arises for large oscillations at the scale of the diameter, D, with a period scaling as O(D/U), where U is the characteristic flow velocity. If the streams are of different temperatures, the oscillations result in experimental fluctuations (thermal striping) at the pipe wall in the outlet branch that can accelerate thermal-mechanical fatigue and ultimately cause pipe failure. The importance of this phenomenon has prompted the nuclear energy modeling and simulation community to establish a benchmark to test the ability of computational fluid dynamics (CFD) codes to predict thermal striping. The benchmark is based on thermal and velocity data measured in an experiment designed specifically for this purpose. Thermal striping is intrinsically unsteady and hence not accessible to steady state simulation approaches such as steady state Reynolds-averaged Navier-Stokes (RANS) models.1 Consequently, one must consider either unsteady RANS or large eddy simulation (LES). This report compares the results for three LES codes: Nek5000, developed at Argonne National Laboratory (USA), and Cabaret and Conv3D, developed at the Moscow Institute of Nuclear Energy Safety at (IBRAE) in Russia. Nek5000 is based on the spectral element method (SEM), which is a high-order weighted …

Fish passage conditions through a Francis turbine and a regulating outlet (RO) at Cougar Dam on the south fork of the McKenzie River in Oregon were evaluated by Pacific Northwest National Laboratory for the U.S. Army Corps of Engineers, Portland District, using Sensor Fish devices. The objective of the study was to describe and compare passage exposure conditions, identifying potential fish injury regions encountered during passage via specific routes. The RO investigation was performed in December 2009 and the turbine evaluation in January 2010, concurrent with HI-Z balloon-tag studies by Normandeau Associates, Inc. Sensor Fish data were analyzed to estimate 1) exposure conditions, particularly exposure to severe collision, strike, and shear events by passage route sub-regions; 2) differences in passage conditions between passage routes; and 3) relationships to live-fish injury and mortality data estimates. Comparison of the three passage routes evaluated at Cougar Dam indicates that the RO passage route through the 3.7-ft gate opening was relatively the safest route for fish passage under the operating conditions tested; turbine passage was the most deleterious. These observations were supported also by the survival and malady estimates obtained from live-fish testing. Injury rates were highest for turbine passage. Compared to mainstem Columbia …

Energy recovery linacs (ERLs) are an emerging generation of accelerators promising to revolutionize the fields of high-energy physics and photon sciences. These accelerators combine the advantages of linear accelerators with that of storage rings, and hold the promise of delivering electron beams of unprecedented power and quality. Use of superconducting radio-frequency (SRF) cavities converts ERLs into nearly perfect 'perpetuum mobile' accelerators, wherein the beam is accelerated to a desirable energy, used, and then gives the energy back to the RF field. One potential weakness of these devices is transverse beam break-up instability that could severely limit the available beam current. In this paper, I present a method of suppressing these dangerous effects using a natural phenomenon in the accelerators, viz., the chromaticity of the transverse motion.

The main function of the CO instrument is to provide continuous accurate measurements of carbon monoxide mixing ratio at the ARM SGP Central Facility (CF) 60-meter tower (36.607 °N, 97.489 °W, 314 meters above sea level). The essential feature of the control and data acquisition system is to record signals from a Thermo Electron 48C and periodically calibrate out zero and span drifts in the instrument using the combination of a CO scrubber and two concentrations of span gas (100 and 300 ppb CO in air). The system was deployed on May 25, 2005.

A theory of Reversed Shear Alfven Eigenmodes (RSAEs) is developed for reversed magnetic field shear plasmas when the safety factor minimum, qmin, is at or above a rational value. The modes we study are known sometimes as either the bottom of the frequency sweep or the down sweeping RSAEs. We show that the ideal MHD theory is not compatible with the eigenmode solution in the reversed shear plasma with qmin above integer values. Corrected by special analytic FLR condition MHD dispersion of these modes nevertheless can be developed. Large radial scale part of the analytic RSAE solution can be obtained from ideal MHD and expressed in terms of the Legendre functions. The kinetic equation with FLR effects for the eigenmode is solved numerically and agrees with the analytic solutions. Properties of RSAEs and their potential implications for plasma diagnostics are discussed.

Li pellet conditioning in TFTR results in a reduction of the edge electron density which allows increased neutral beam penetration, central heating, and fueling. Consequently the temperature profiles became more peaked with higher central Ti, Te, and neutron emission rates.

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2000, the annual number of new international parental child abduction cases reported to the Department of State--many of which likely involved air travel--has nearly tripled. Such abductions occur when a parent, family member, or person acting on behalf thereof, takes a child to another country in violation of the custodial parent's or guardian's rights. Once a child is abducted, the laws, policies, and procedures of the foreign country determine the child's return. Thus, preventing such abductions can help keep parents and children from being separated for a long period or indefinitely. As requested, this report addresses (1) the policies and measures airlines, federal agencies, and others have to prevent international parental child abductions on airline flights and (2) options federal agencies, airlines, and others could consider for helping prevent such abductions on airline flights, as well as the advantages and limitations of those options. To perform this work, GAO reviewed applicable laws and policies, interviewed government officials, and surveyed airlines and nonprofit associations."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1994, FCC has made over 520 megahertz (a measure of quantity) of spectrum available for new uses, such as wireless broadband, through a process that can be lengthy. Because most of the usable spectrum in the United States has been allocated to existing uses, FCC must change its rules to move spectrum from an existing use to a new use, a process known as repurposing spectrum. Yet, this process can be lengthy—from 7 to 15 years for the six repurposings that GAO reviewed. Four factors contribute to the time it takes FCC to repurpose spectrum: the regulatory nature of the process, which to some extent is guided by statute; opposition of incumbent users, who could be required to vacate spectrum; coordination challenges between FCC and the National Telecommunications and Information Administration (NTIA), which oversees federal agencies’ use of spectrum, on the repurposing of federal spectrum for commercial use; and concerns about interference from users of spectrum in adjacent bands of spectrum. FCC has identified voluntary approaches that it thinks could speed the process, but these approaches generally require congressional approval and face some stakeholder opposition."

To support the analyses related to the conversion of the BR2 core from highly-enriched (HEU) to low-enriched (LEU) fuel, the thermal-hydraulics codes PLTEMP and RELAP-3D are used to evaluate the safety margins during steady-state operation (PLTEMP), as well as after a loss-of-flow, loss-of-pressure, or a loss of coolant event (RELAP). In the 1-D PLTEMP and RELAP simulations, conduction in the azimuthal and axial directions is not accounted. The very good thermal conductivity of the cladding and the fuel meat and significant temperature gradients in the lateral directions (axial and azimuthal directions) could lead to a heat flux distribution that is significantly different than the power distribution. To evaluate the significance of the lateral heat conduction, 3-D computational fluid dynamics (CFD) simulations, using the CFD code STAR-CD, were performed. Safety margin calculations are typically performed for a hot stripe, i.e., an azimuthal region of the fuel plates/coolant channel containing the power peak. In a RELAP model, for example, a channel between two plates could be divided into a number of RELAP channels (stripes) in the azimuthal direction. In a PLTEMP model, the effect of azimuthal power peaking could be taken into account by using engineering factors. However, if the thermal mixing …

This grant covered only a period of 4 months as the major portion of the award was returned to DOE due to an award of funding from NIH that covered the same research objectives. A letter regarding the termination of the research is attached as the last page of the Final Report. The research conducted was limited due to the short period of this grant, but the results obtained in that period are outlined in the Final Report. The studies addressed in the research effort were directed at a problem that is of critical importance to the in vivo application of the alpha-particle emitting radionuclide At-211. That problem, low in vivo stability of many astatinated molecules, severely limits the use of At-211 in therapeutic applications. The advances sought in the studies were expected to expand the types of biomolecules that can be used as carriers of At-211, and provide improved in vivo targeting of the radiation dose compared with the dose delivered to normal tissue.

A letter report issued by the Government Accountability Office with an abstract that begins "In 2007, following reports of poor case management for outpatients at Walter Reed Army Medical Center, the Departments of Defense (DOD) and Veterans Affairs (VA) jointly developed the Federal Recovery Coordination Program (FRCP) to coordinate the clinical and nonclinical services needed by severely wounded, ill, and injured servicemembers and veterans. The FRCP, which continues to expand, is administered by VA, and the care coordinators, called Federal Recovery Coordinators (FRC), are VA employees. This report examines (1) whether servicemembers and veterans who need FRCP services are being identified and enrolled in the program, (2) staffing challenges confronting the FRCP, and (3) challenges facing the FRCP in its efforts to coordinate care for enrollees. GAO reviewed FRCP policies and procedures and conducted over 170 interviews of FRCP officials, FRCs, headquarters officials and staff of DOD and VA case management programs, and staff at medical facilities where FRCs are located."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy's (DOE) Office of Environmental Management (EM) is responsible for storing and managing a total of about 13,000 metric tons of nuclear waste--spent nuclear fuel and high-level waste--at five DOE sites in Colorado, Idaho, New York, South Carolina, and Washington. Also, a joint DOE-Navy program stores spent nuclear fuel from warships at DOE's Idaho site. DOE and the Navy intended to permanently dispose of this nuclear waste at a repository planned for Yucca Mountain in Nevada. However, that plan is now in question because of actions taken to terminate the site. This report assesses (1) agreements DOE and the Navy have with states at the five sites and the effects a termination of the Yucca Mountain repository would have on their ability to fulfill these agreements; (2) the effects a termination would have on DOE's and the Navy's operations and costs for storing the waste; and (3) DOE's and the Navy's plans to mitigate these potential effects. GAO reviewed state agreements and DOE plans, visited waste facilities, and interviewed federal and state officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Health Resources and Services Administration (HRSA), within in the Department of Health and Human Services (HHS), oversees the 340B Drug Pricing Program, through which participating drug manufacturers give certain entities within the health care safety net--known as covered entities--access to discounted prices on outpatient drugs. Covered entities include specified federal grantees and hospitals. The number of covered entity sites has nearly doubled in the past 10 years to over 16,500. The Patient Protection and Affordable Care Act (PPACA) mandated that GAO address questions related to the 340B program. GAO examined: (1) the extent to which covered entities generate 340B revenue, factors that affect revenue generation, and how they use the program; (2) how manufacturers' distribution of drugs at 340B prices affects covered entities' or non-340B providers' access to drugs; and (3) HRSA's oversight of the 340B program. GAO reviewed key laws and guidance, analyzed relevant data, and conducted interviews with 61 340B program stakeholders selected to represent a range of perspectives, including HRSA, 29 covered entities, 10 manufacturers and representatives, and 21 others. Selection of stakeholders was judgmental and thus, responses are not generalizable."
