Field Test Report: Preliminary Aquifer Test Characterization Results for Well 299-W15-225: Supporting Phase I of the 200-ZP-1 Groundwater Operable Unit Remedial Design (open access)

Field Test Report: Preliminary Aquifer Test Characterization Results for Well 299-W15-225: Supporting Phase I of the 200-ZP-1 Groundwater Operable Unit Remedial Design

This report examines the hydrologic test results for both local vertical profile characterization and large-scale hydrologic tests associated with a new extraction well (well 299-W15-225) that was constructed during FY2009 for inclusion within the future 200-West Area Groundwater Treatment System that is scheduled to go on-line at the end of FY2011. To facilitate the analysis of the large-scale hydrologic test performed at newly constructed extraction well 299-W15-225 (C7017; also referred to as EW-1 in some planning documents), the existing 200-ZP-1 interim pump-and-treat system was completely shut-down ~1 month before the performance of the large-scale hydrologic test. Specifically, this report 1) applies recently developed methods for removing barometric pressure fluctuations from well water-level measurements to enhance the detection of hydrologic test and pump-and-treat system effects at selected monitor wells, 2) analyzes the barometric-corrected well water-level responses for a preliminary determination of large-scale hydraulic properties, and 3) provides an assessment of the vertical distribution of hydraulic conductivity in the vicinity of newly constructed extraction well 299-W15-225. The hydrologic characterization approach presented in this report is expected to have universal application for meeting the characterization needs at other remedial action sites located within unconfined and confined aquifer systems.

GROUNDWATER RADIOIODINE: PREVALENCE, BIOGEOCHEMISTRY, AND POTENTIAL REMEDIAL APPROACHES (open access)

GROUNDWATER RADIOIODINE: PREVALENCE, BIOGEOCHEMISTRY, AND POTENTIAL REMEDIAL APPROACHES

Iodine-129 ({sup 129}I) has not received as much attention in basic and applied research as other contaminants associated with DOE plumes. These other contaminants, such as uranium, plutonium, strontium, and technetium are more widespread and exist at more DOE facilities. Yet, at the Hanford Site and the Savannah River Site {sup 129}I occurs in groundwater at concentrations significantly above the primary drinking water standard and there is no accepted method for treating it, other than pump-and-treat systems. With the potential arrival of a 'Nuclear Renaissance', new nuclear power facilities will be creating additional {sup 129}I waste at a rate of 1 Ci/gigawatts energy produced. If all 22 proposed nuclear power facilities in the U.S. get approved, they will produce more {sup 129}I waste in seven years than presently exists at the two facilities containing the largest {sup 129}I inventories, ({approx}146 Ci {sup 129}I at the Hanford Site and the Savannah River Site). Hence, there is an important need to fully understand {sup 129}I behavior in the environment to clean up existing plumes and to support the expected future expansion of nuclear power production. {sup 129}I is among the key risk drivers at all DOE nuclear disposal facilities where {sup 129}I …

HIV/AIDS: Federal and State Efforts to Identify Infected Individuals and Connect Them to Care (open access)

HIV/AIDS: Federal and State Efforts to Identify Infected Individuals and Connect Them to Care

A letter report issued by the Government Accountability Office with an abstract that begins "Of the estimated 1.1 million Americans living with HIV, not all are aware of their HIV-positive status. Timely testing of HIV-positive individuals is important to improve health outcomes and to slow the disease's transmission. It is also important that individuals have access to HIV care after being diagnosed, but not all diagnosed individuals are receiving such care. The Centers for Disease Control and Prevention (CDC) provides grants to state and local health departments for HIV prevention and collects data on HIV. In 2006, CDC recommended routine HIV testing for all individuals ages 13-64. The Health Resources and Services Administration (HRSA) provides grants to states and localities for HIV care and services. GAO was asked to examine issues related to identifying individuals with HIV and connecting them to care. This report examines: 1) CDC and HRSA's coordination on HIV activities and steps they have taken to encourage routine HIV testing; 2) implementation of routine HIV testing by select state and local health departments; 3) available information on CDC funding for HIV testing; and 4) available data on the number of HIV-positive individuals not receiving care for HIV. …

Long-Range Ballistic Missile Defense in Europe (open access)

Long-Range Ballistic Missile Defense in Europe

In early 2007, after several years of internal discussions and consultations with Poland and the Czech Republic, the Bush Administration formally proposed to defend against an Iranian missile threat by deploying a ground-based mid-course defense (GMD) element in Europe as part of the global U.S. BMDS (Ballistic Missile Defense System). The system would have included 10 interceptors in Poland, a radar in the Czech Republic, and another radar that would have been deployed in a country closer to Iran, to be completed by 2013 at a reported cost of at least $4 billion. This report is designed to retain background information and analysis of the Bush-proposed European BMD initiative up to the Obama Administration's decision to cancel it.

New Drug Approval: FDA Needs to Enhance Its Oversight of Drugs Approved on the Basis of Surrogate Endpoints (open access)

New Drug Approval: FDA Needs to Enhance Its Oversight of Drugs Approved on the Basis of Surrogate Endpoints

A letter report issued by the Government Accountability Office with an abstract that begins "Before approving a drug, the Food and Drug Administration (FDA) assesses a drug's effectiveness. This assessment may be based on evidence showing that a drug has a positive impact on a surrogate endpoint--a laboratory measure, such as blood pressure--instead of more direct clinical evidence, like preventing strokes. After approval, FDA often requires or requests a drug sponsor to further study the drug. Concerns have been raised about FDA's reliance on surrogate endpoints and its oversight of postmarketing studies. This report provides information on (1) all drug applications approved based on surrogate endpoints in FDA's accelerated approval process, (2) a subset of applications for potentially innovative drugs approved based on surrogate endpoints under FDA's traditional process, and (3) FDA's oversight of postmarketing studies. GAO identified drugs approved based on surrogate endpoints, obtained the status of related postmarketing studies, and reviewed FDA's oversight of a sample of 35 studies it required under its accelerated approval process, selected to include studies which were at varying levels of completion."

Performance of particle in cell methods on highly concurrent computational architectures (open access)

Performance of particle in cell methods on highly concurrent computational architectures

Particle in cell (PIC) methods are effective in computing Vlasov-Poisson system of equations used in simulations of magnetic fusion plasmas. PIC methods use grid based computations, for solving Poisson’s equation or more generally Maxwell’s equations, as well as Monte-Carlo type methods to sample the Vlasov equation. The presence of two types of discretizations, deterministic field solves and Monte-Carlo methods for the Vlasov equation, pose challenges in understanding and optimizing performance on today large scale computers which require high levels of concurrency. These challenges arises from the need to optimize two very different types of processes and the interactions between them. Modern cache based high-end computers have very deep memory hierarchies and high degrees of concurrency which must be utilized effectively to achieve good performance. The effective use of these machines requires maximizing concurrency by eliminating serial or redundant work and minimizing global communication. A related issue is minimizing the memory traffic between levels of the memory hierarchy because performance is often limited by the bandwidths and latencies of the memory system. This paper discusses some of the performance issues, particularly in regard to parallelism, of PIC methods. The gyrokinetic toroidal code (GTC) is used for these studies and a new …

Recovery Act: Funds Continue to Provide Fiscal Relief to States and Localities, While Accountability and Reporting Challenges Need to Be Fully Addressed

A letter report issued by the Government Accountability Office with an abstract that begins "This report, the third in response to a mandate under the American Recovery and Reinvestment Act of 2009 (Recovery Act), addresses the following objectives: (1) selected states' and localities' uses of Recovery Act funds, (2) the approaches taken by the selected states and localities to ensure accountability for Recovery Act funds, and (3) states' plans to evaluate the impact of Recovery Act funds. GAO's work for the report is focused on 16 states and certain localities in those jurisdictions as well as the District of Columbia (District)-- representing about 65 percent of the U.S. population and two-thirds of the intergovernmental federal assistance available. Under the Recovery Act, GAO collected and analyzed documents and interviewed state and local officials. GAO also analyzed federal agency guidance and spoke with Office of Management and Budget (OMB) officials and with program officials at the federal agencies overseeing Recovery Act programs."

Selective Separation of Trivalent Actinides from Lanthanides by Aqueous Processing with Introduction of Soft Donor Atoms (open access)

Selective Separation of Trivalent Actinides from Lanthanides by Aqueous Processing with Introduction of Soft Donor Atoms

With increased application of MOX fuels and longer burnup times for conventional fuels, higher concentrations of the transplutonium actinides Am and Cm (and even heavier species like Bk and Cf) will be produced. The half-lives of the Am isotopes are significantly longer than those of the most important long-lived, high specific activity lanthanides or the most common Cm, Bk and Cf isotopes, thus the greatest concern as regards long-term radiotoxicity. With the removal and transmutation of Am isotopes, radiation levels of high level wastes are reduced to near uranium mineral levels within less than 1000 years as opposed to the time-fram if they remain in the wastes.

Tax Administration: Opportunities Exist for IRS to Enhance Taxpayer Service and Enforcement for the 2010 Filing Season

A letter report issued by the Government Accountability Office with an abstract that begins "Preparing for the tax filing season is a significant undertaking for Internal Revenue Service (IRS). The filing season is when most individuals file their tax returns, receive refunds, and contact IRS if they have questions. As returns are received, IRS begins a series of automated compliance checks to correct errors on tax returns and ensure that refunds are justified. For example, IRS rejects electronically filed returns with basic errors requiring taxpayers to correct and resubmit them. It uses what is called "math error authority" to automatically correct obvious noncompliance such as violations of limits on deductions or credits, which allows IRS to avoid costly audits. IRS must begin preparing for each filing season months in advance and preparations include the following. (1) Revising tax forms and publications to implement tax law changes. Recent major law changes that affected the 2009 filing season include the (a) Economic Stimulus Act of 2008, which contained the recovery rebate credit allowing taxpayers who did not receive the full economic stimulus payment last year to claim some or all of the unpaid credit on their 2008 returns; (b) Housing and Economic …

Validation for the Permanganate Digestion of Reillex HPQ Anion Resin (open access)

Validation for the Permanganate Digestion of Reillex HPQ Anion Resin

The flowsheet for the digestion of Reillex{trademark} HPQ was validated both under the traditional alkaline conditions and under strongly acidic conditions. Due to difficulty in performing a pH adjustment in the large tank where this flowsheet must be performed, the recommended digestion conditions were changed from pH 8-10 to 8 M HNO{sub 3}. Thus, no pH adjustment of the solution is required prior to performing the permanganate addition and digestion and the need to sample the digestion tank to confirm appropriate pH range for digestion may be avoided. Neutralization of the acidic digestion solution will be performed after completion of the resin digestion cycle. The amount of permanganate required for this type of resin (Reillex{trademark} HPQ) was increased from 1 kg/L resin to 4 kg/L resin to reduce the amount of residual resin solids to a minimal amount (<5%). The length of digestion time at 70 C remains unchanged at 15 hours. These parameters are not optimized but are expected to be adequate for the conditions. The flowsheet generates a significant amount of fine manganese dioxide (MnO{sub 2}) solids (1.71 kg/L resin) and involves the generation of a significant liquid volume due to the low solubility of permanganate. However, since …

Wireless Sensor Network for Advanced Energy Management Solutions

Eaton has developed an advanced energy management solution that has been deployed to several Industries of the Future (IoF) sites. This demonstrated energy savings and reduced unscheduled downtime through an improved means for performing predictive diagnostics and energy efficiency estimation. Eaton has developed a suite of online, continuous, and inferential algorithms that utilize motor current signature analysis (MCSA) and motor power signature analysis (MPSA) techniques to detect and predict the health condition and energy usage condition of motors and their connect loads. Eaton has also developed a hardware and software platform that provided a means to develop and test these advanced algorithms in the field. Results from lab validation and field trials have demonstrated that the developed advanced algorithms are able to detect motor and load inefficiency and performance degradation. Eaton investigated the performance of Wireless Sensor Networks (WSN) within various industrial facilities to understand concerns about topology and environmental conditions that have precluded broad adoption by the industry to date. A Wireless Link Assessment System (WLAS), was used to validate wireless performance under a variety of conditions. Results demonstrated that wireless networks can provide adequate performance in most facilities when properly specified and deployed. Customers from various IoF expressed …

ASSESSMENT OF UNCERTAINTY IN THE RADIATION DOSES FOR THE TECHA RIVER DOSIMETRY SYSTEM (open access)

ASSESSMENT OF UNCERTAINTY IN THE RADIATION DOSES FOR THE TECHA RIVER DOSIMETRY SYSTEM

In order to provide more accurate and precise estimates of individual dose (and thus more precise estimates of radiation risk) for the members of the ETRC, a new dosimetric calculation system, the Techa River Dosimetry System-2009 (TRDS-2009) has been prepared. The deterministic version of the improved dosimetry system TRDS-2009D was basically completed in April 2009. Recent developments in evaluation of dose-response models in light of uncertain dose have highlighted the importance of different types of uncertainties in the development of individual dose estimates. These include uncertain parameters that may be either shared or unshared within the dosimetric cohort, and also the nature of the type of uncertainty as aleatory or epistemic and either classical or Berkson. This report identifies the nature of the various input parameters and calculational methods incorporated in the Techa River Dosimetry System (based on the TRDS-2009D implementation), with the intention of preparing a stochastic version to estimate the uncertainties in the dose estimates. This report reviews the equations, databases, and input parameters, and then identifies the author’s interpretations of their general nature. It presents the approach selected so that the stochastic, Monte-Carlo, implementation of the dosimetry System - TRDS-2009MC - will provide useful information regarding the …

Building America Best Practices Series, Volume 9: Builders Challenge Guide to 40% Whole-House Energy Savings in the Hot-Dry and Mixed-Dry Climates

This best practices guide is the ninth in a series of guides for builders produced by the U.S. Department of Energy’s Building America Program. This guide book is a resource to help builders design and construct homes that are among the most energy-efficient available, while addressing issues such as building durability, indoor air quality, and occupant health, safety, and comfort. With the measures described in this guide, builders in the hot-dry and mixed-dry climates can achieve homes that have whole house energy savings of 40% over the Building America benchmark (a home built to mid-1990s building practices roughly equivalent to the 1993 Model Energy Code) with no added overall costs for consumers. These best practices are based on the results of research and demonstration projects conducted by Building America’s research teams. The guide includes information for managers, designers, marketers, site supervisors, and subcontractors, as well as case studies of builders who are successfully building homes that cut energy use by 40% in the hot-dry and mixed-dry climates.

Centers for Medicare and Medicaid Services: Deficiencies in Contract Management Internal Control Are Pervasive

A letter report issued by the Government Accountability Office with an abstract that begins "As a result of internal control deficiencies discussed in GAO's 2007 report on certain contracts at the Centers for Medicare and Medicaid Services (CMS), GAO was asked to identify the extent to which CMS (1) implemented effective control procedures over contract actions, and (2) established a strong control environment for contract management. GAO used a statistical random sample of 2008 CMS contract actions (including contract awards and modifications) to assess CMS internal control procedures. The results were projected to the population of 2008 CMS contract actions. GAO also determined the extent to which CMS implemented recommendations GAO made in 2007 to improve internal control over contracting and payments to contractors. GAO reviewed contract file documentation and interviewed senior acquisition management officials."
