A letter report issued by the Government Accountability Office with an abstract that begins "The F-35 Lightning II, also known as the Joint Strike Fighter (JSF), is the Department of Defense's (DOD) most costly and ambitious aircraft acquisition, seeking to simultaneously develop and field three aircraft variants for the Air Force, Navy, Marine Corps, and eight international partners. The JSF is critical for recapitalizing tactical air forces and will require a long-term commitment to very large annual funding outlays. The current estimated investment is $382 billion to develop and procure 2,457 aircraft. This report, prepared in response to a congressional mandate in the National Defense Authorization Act for Fiscal Year 2010, discusses (1) program cost and schedule changes and their implications on affordability; (2) progress made during 2010; (3) design and manufacturing maturity; and (4) test plans and progress. GAO's work included analyses of a wide range of program documents and interviews with defense and contractor officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The American Recovery and Reinvestment Act of 2009 (Recovery Act) provided $3.2 billion for the Department of Energy's (DOE) Energy Efficiency and Conservation Block Grant Program (EECBG) to develop and manage projects to improve energy efficiency and reduce energy use and fossil fuel emissions. The Recovery Act requires GAO to review funds made available under the act and to comment on recipients' estimates of jobs created or retained. GAO examined (1) how EECBG recipients used EECBG funds and challenges they faced, if any; (2) DOE and recipients' oversight and monitoring activities and challenges, if any; (3) the extent to which the EECBG program is meeting Recovery Act and program goals for energy savings; and (4) the quality of jobs data reported by Recovery Act recipients, particularly EECBG recipients. GAO also updates the status of open recommendations from previous bimonthly and recipient reporting reviews. GAO analyzed DOE recipient data and interviewed DOE officials and a nonprobability sample of EECBG recipients, among other things."

A letter report issued by the Government Accountability Office with an abstract that begins "According to the Federal Bureau of Investigation (FBI), an estimated 1.3 million violent crimes occurred nationwide in 2009. The Department of Justice (DOJ) law enforcement components--the Bureau of Alcohol, Tobacco, Firearms and Explosives; Drug Enforcement Administration; FBI, and U.S. Marshals Service--have overlapping jurisdiction over violent crime investigations, specifically when they involve illegal drugs, gang violence, firearms, explosives, arson, and fugitive apprehension. As requested, GAO assessed the extent to which selected agents are clear on their agencies' roles and responsibilities, and how components determine and coordinate roles and responsibilities to avoid unnecessary use of resources. GAO reviewed documents such as department directives and interviewed DOJ component officials in headquarters and nine cities, which were selected based on population and the presence of all DOJ components. GAO also surveyed a randomly selected, nongeneralizable sample of 315 field agents. The results provide valuable information about the range of perspectives of surveyed agents."

A letter report issued by the Government Accountability Office with an abstract that begins "CMS, the agency within HHS that manages Medicare and Medicaid, contracts with state survey agencies to investigate complaints about nursing homes from residents, family members, and others. CMS helps assure the adequacy of state complaint processes by issuing guidance, monitoring data that state survey agencies enter into CMS's database, and annually assessing performance against specific standards. Concerns have been raised about the timeliness and adequacy of complaint investigations and CMS's oversight. GAO examined (1) complaints received, investigated, and substantiated by state survey agencies; (2) whether those agencies were meeting CMS performance standards and other requirements; and (3) the effectiveness of CMS's oversight. In addition to analyzing CMS data on complaints and performance reviews, GAO examined CMS guidance and conducted interviews with officials from three high- and three low-performing state survey agencies and their CMS regional offices. GAO addressed data reliability concerns by reporting only data we determined to be reliable."

Testimony issued by the Government Accountability Office with an abstract that begins "Indian tribes are among the most economically distressed groups in the United States. In 2008, the U.S. Census Bureau reported that the poverty rate among American Indian and Alaska Natives was almost twice as high as the population as a whole--27 percent compared with 15 percent. Residents of tribal lands often lack basic infrastructure, such as water and sewer systems, and sufficient technology infrastructure. Without such infrastructure, tribal communities often find it difficult to compete successfully in the economic mainstream. This testimony statement summarizes GAO's observations on (1) five broad categories of unique issues that may create uncertainty and therefore affect economic activity in Indian country and (2) tribes' use of special gaming and small business contracting provisions. It is based on prior GAO reports."

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses the findings from our recent work on fragmentation, overlap, and potential duplication in federally funded employment and training programs and our prior work on the Workforce Investment Act of 1998 (WIA). We recently issued two reports addressing fragmentation, overlap, and potential duplication in federal programs--one that outlined opportunities to reduce potential duplication across a wide range of federal programs and another that focused more specifically on employment and training programs. This work and our larger body of work in the area will help government policymakers address the rapidly building fiscal pressures facing our nation's government--pressures that stem, in part, from our mounting debt and sustained high unemployment. Our work to examine fragmentation, overlap, and potential duplication in employment and training programs has a long history. As early as the 1990s we issued a series of reports that raised questions about the efficiency and effectiveness of the federally funded employment and training system, and we concluded that a structural overhaul and consolidation of these programs was needed. Partly in response to these concerns, Congress passed WIA. The purpose of WIA, in part, was to transform the …

This research has accomplished its primary objectives of developing accurate and efficient radiation codes, validating them with measurements and higher resolution models, and providing these advancements to the global modeling community to enhance the treatment of cloud and radiative processes in weather and climate prediction models. A critical component of this research has been the development of the longwave and shortwave broadband radiative transfer code for general circulation model (GCM) applications, RRTMG, which is based on the single-column reference code, RRTM, also developed at AER. RRTMG is a rigorously tested radiation model that retains a considerable level of accuracy relative to higher resolution models and measurements despite the performance enhancements that have made it possible to apply this radiation code successfully to global dynamical models. This model includes the radiative effects of all significant atmospheric gases, and it treats the absorption and scattering from liquid and ice clouds and aerosols. RRTMG also includes a statistical technique for representing small-scale cloud variability, such as cloud fraction and the vertical overlap of clouds, which has been shown to improve cloud radiative forcing in global models. This development approach has provided a direct link from observations to the enhanced radiative transfer provided by …

We report on the mineralogy, petrology, chemistry, oxygen isotopes, {sup 26}Al-{sup 26}Mg and {sup 36}Cl-{sup 36}S isotope systematics of the Allende chondrule Al3509 discovered and described by [1] and [2]. This spherical object ({approx}1cm {phi}) contains {approx}10% Na and 1% Cl, and nearly pure {sup 129}Xe [({sup 129}Xe/{sup 127}I) = 1.1 x 10{sup -4} (3)]. This high enrichment in halogens makes it of interest in searching for radiogenic {sup 36}S from {sup 36}Cl (t{sub 1/2} {approx} 0.3 Ma) decay. While there is strong evidence for the presence of {sup 36}Cl in sodalite and wadalite in CV CAIs [4,5], some sodalites show no evidence for excesses of {sup 36}S ({sup 36}S*). In contrast, high inferred initial {sup 36}Cl/{sup 35}Cl = 2 x 10{sup -5} has been found in wadalite from the Allende CAI AJEF [5]. The observed {sup 36}S excesses in sodalite are not correlated with radiogenic {sup 26}Mg, decay product of {sup 26}Al (t{sub 1/2} {approx} 0.72 Ma) [4]. From the inferred initial {sup 36}Cl/{sup 35}Cl ratios and consideration of both AGB and SNe stellar sources, {sup 36}Cl must be the product of charged particle irradiation within the early solar system. However, neither the specific nuclear production mechanism nor the …

This report is one of four reports written to provide background information regarding immobilization technologies remaining under consideration for supplemental immobilization of Hanford's low-activity waste. This paper provides the reader a general understanding of joule-heated ceramic lined melters and their application to Hanford's low-activity waste.

The Savannah River Remediation (SRR) Defense Waste Processing Facility (DWPF) has identified a technical issue related to the amount of antifoam added to the Chemical Process Cell (CPC). Specifically, due to the long duration of the concentration and reflux cycles for the Sludge Receipt and Adjustment Tank (SRAT), additional antifoam has been required. The additional antifoam has been found to impact the melter flammability analysis as an additional source of carbon and hydrogen. To better understand and control the carbon and hydrogen contributors to the melter flammability analysis, SRR's Waste Solidification Engineering (WSE) has requested, via a Technical Task Request (TTR), that the Savannah River National Laboratory (SRNL) conduct an error evaluation of the measurements of key Slurry Mix Evaporator (SME) anions. SRNL issued a Task Technical and Quality Assurance Plan (TTQAP) [2] in response to that request, and the work reported here was conducted under the auspices of that TTQAP. The TTR instructs SRNL to conduct an error evaluation of anion measurements generated by the DWPF Laboratory using Ion Chromatography (IC) performed on SME samples. The anions of interest include nitrate, oxalate, and formate. Recent measurements of SME samples for these anions as well as measurements of total organic …

This report is one in the series of 'POINT' reports that over the years have presented temperature dependent cross sections for the then current version of ENDF/B. In each case I have used my personal computer at home and publicly available data and codes. I have used these in combination to produce the temperature dependent cross sections used in applications and presented in this report. I should mention that today anyone with a personal computer can produce these results. The latest ENDF/B-VII.1 beta2 data library was recently and is now freely available through the National Nuclear Data Center (NNDC), Brookhaven National Laboratory. This release completely supersedes all preceding releases of ENDF/B. As distributed the ENDF/B-VII.1 data includes cross sections represented in the form of a combination of resonance parameters and/or tabulated energy dependent cross sections, nominally at 0 Kelvin temperature. For use in our applications the ENDF/B-VII.1 library has been processed into cross sections at eight neutron reactor like temperatures, between 0 and 2100 Kelvin, in steps of 300 Kelvin (the exception being 293.6 Kelvin, for exact room temperature at 20 Celsius). It has also been processed to five astrophysics like temperatures, 1, 10, 100 eV, 1 and 10 keV. …

Ca-Al-rich inclusions (CAIs) found in primitive chondrites record processes and conditions of the earliest solar system as they are the oldest known solid objects formed in the solar system [1,2]. CAIs with fractionation and unidentified nuclear anomalies (FUN CAIs; [3]) are very rare and thusfar found exclusively in CV carbonaceous chondrites (e.g., Allende and Vigarano)[4]. FUN CAIs are characterized by large nucleosynthetic anomalies in several elements (Ca, Ti, Si, Sr, Ba, Nd, and Sm), large mass-dependant isotope fractionation (Mg, Si, and O), and very little initial {sup 26}Al [4,5 and reference therein]. Formation of FUN CAIs by thermal processing of presolar dust aggregates prior to the injection of {sup 26}Al into the protoplanetary disk has been proposed. More recently [5] proposed that FUN CAIs formed from a protosolar molecular cloud after injection of {sup 26}Al but before {sup 26}Al and {sup 27}Al were completely homogenized. Therefore discovering more FUN CAIs to perform U-Pb and other short-lived chronometric dating will provide key constraints on the age of the solar system, the isotopic composition of the protosolar molecular cloud, the earliest stages of the thermal processing in the solar system and the timing of {sup 26}Al and other short-lived radionuclide injection into …

Access to Hanford's single-shell radioactive waste storage tank C-107 was significantly improved when workers completed the cut of a 55-inch diameter hole in the top of the tank. The core and its associated cutting equipment were removed from the tank and encased in a plastic sleeve to prevent any potential spread of contamination. The larger tank opening allows use of a new more efficient robotic arm to complete tank retrieval.

Savannah River Remediation, LLC (SRR) is implementing a statistical sampling strategy for In-Service Inspection (ISI) of Liquid Waste (LW) Tanks at the United States Department of Energy's Savannah River Site (SRS) in Aiken, South Carolina. As a component of SRS's corrosion control program, the ISI program assesses tank wall structural integrity through the use of ultrasonic testing (UT). The statistical strategy for ISI is based on the random sampling of a number of vertically oriented unit areas, called strips, within each tank. The number of strips to inspect was determined so as to attain, over time, a high probability of observing at least one of the worst 5% in terms of pitting and corrosion across all tanks. The probability estimation to determine the number of strips to inspect was performed using the hypergeometric distribution. Statistical tolerance limits for pit depth and corrosion rates were calculated by fitting the lognormal distribution to the data. In addition to the strip sampling strategy, a single strip within each tank was identified to serve as the baseline for a longitudinal assessment of the tank safe operational life. The statistical sampling strategy enables the ISI program to develop individual profiles of LW tank wall structural …
