A letter report issued by the Government Accountability Office with an abstract that begins "The National Nuclear Security Administration (NNSA)--a semiautonomous agency within the Department of Energy (DOE)-- proposed in March 2010 a new acquisition strategy that includes consolidating the management and operating (M&O) contracts for two of its eight sites--the Y-12 National Security Complex (Y-12) in Tennessee and the Pantex Plant in Texas--and consolidating all construction projects for all of its sites under a single, enterprise-wide contract. NNSA anticipates that this strategy will reduce costs, enhance mission performance, and improve construction management. NNSA's sites are overseen by colocated federal site offices. GAO was asked to assess NNSA's preliminary proposals for (1) a consolidated M&O contract for Y-12 and Pantex and (2) an enterprise-wide construction contract. GAO reviewed analyses supporting NNSA's acquisition strategy; examined agency directives and guidance; and interviewed DOE, NNSA, and contractor officials."

A letter report issued by the Government Accountability Office with an abstract that begins "To support ongoing operations, the Army gives priority to providing personnel to its operating forces over its support organizations, including Training and Doctrine Command (TRADOC).TRADOC performs various functions, such as developing warfighting doctrine and providing training. To help manage its workforce, TRADOC has taken certain actions, such as relying more on contractors and reassigning other staff to be instructors. In a February 2010 memorandum, the TRADOC Commander stated that because of various factors TRADOC's ability to successfully perform its core competencies and functions was increasingly at risk. House Armed Services Committee report 111-491 directed GAO to evaluate the availability of Army trainers. GAO assessed the extent to which TRADOC has (1) identified the number and type of personnel needed to carry out its training mission and (2) evaluated the impact of its workforce management actions on the quality of training. GAO interviewed key Army and TRADOC officials and reviewed relevant doctrine, guidance, curricula, personnel requirements data, and training survey results."

Correspondence issued by the Government Accountability Office with an abstract that begins "The United States has allocated over $72 billion to secure, stabilize, and rebuild Afghanistan since 2002, and the President requested over $18 billion for these purposes for fiscal year 2012. GAO has on numerous occasions raised doubts about the Government of the Islamic Republic of Afghanistan's (GIRoA) ability to fund its public expenditures--funds spent to provide public services to the Afghan population, such as security, infrastructure projects, and government salaries. In 2005, we reported that Afghanistan had limited resources and recommended that the Secretaries of State and Defense develop plans for funding the Afghan national security forces (ANSF).1 In 2007 and 2008, we reported that it was essential to develop future funding requirements for the ANSF and a strategy for transitioning these responsibilities to GIRoA.2 In 2008, Congress also mandated that the Department of Defense provide a long-term plan for sustaining the ANSF, including future funding requirements. The Department of Defense, however, has yet to provide the Congress an estimate of the cost to sustain the Afghanistan National Security Forces.3 In 2011, we again recommended that the U.S. and international partners develop estimates of the future funding needed …

A letter report issued by the Government Accountability Office with an abstract that begins "The United States has allocated over $72 billion to Afghanistan since 2002. With other international donors, it is focused on transitioning leadership to the Afghan government and has pledged to provide at least 50 percent of its development aid through the Afghan government budget. Improving Afghanistan's public financial management capacity is critical to this transition. In 2010, the Afghan government, consulting with donors, issued a Public Financial Management Roadmap (Roadmap), which outlines goals to improve Afghanistan's capacity to develop a national budget and expend funds. GAO reviewed (1) U.S. efforts to improve the Afghan government's public financial management capacity, including the extent to which they support Roadmap goals, and (2) the extent to which U.S. efforts have improved the government's capacity. GAO reviewed documents and interviewed officials from the U.S. Agency for International Development (USAID); Departments of State, Defense (DOD), and the Treasury (Treasury); World Bank; and Afghan government in Washington, D.C., and Kabul, Afghanistan."

A letter report issued by the Government Accountability Office with an abstract that begins "Recently, concerns have arisen about the use of certain financial derivatives to avoid or evade tax obligations. As requested, this report (1) identifies and evaluates how financial derivatives can be used to avoid or evade tax liability or achieve differing tax results in economically similar situations, (2) evaluates Internal Revenue Service (IRS) actions to address the tax effects of investments in financial derivatives through guidance, and (3) evaluates IRS actions to identify financial derivative products and trends through information from other agencies. GAO reviewed research and IRS documents and interviewed IRS and, Department of the Treasury (Treasury) officials and other experts. GAO analyzed the completion of financial derivative projects on the agencies' Priority Guidance Plans (PGP) from 1996 to 2010."

A letter report issued by the Government Accountability Office with an abstract that begins "To increase the security of federal facilities and information systems, the President issued Homeland Security Presidential Directive 12 (HSPD-12) in 2004. This directive ordered the establishment of a governmentwide standard for secure and reliable forms of ID for employees and contractors who access government-controlled facilities and information systems. The National Institute of Standards and Technology (NIST) defined requirements for such personal identity verification (PIV) credentials based on "smart cards"--plastic cards with integrated circuit chips to store and process data. The Office of Management and Budget (OMB) directed federal agencies to issue and use PIV credentials to control access to federal facilities and systems. GAO was asked to determine the progress that selected agencies have made in implementing the requirements of HSPD-12 and identify obstacles agencies face in implementing those requirements. To perform the work, GAO reviewed plans and other documentation and interviewed officials at the General Services Administration, OMB, and eight other agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "The United States has long advocated for strong oversight of the United Nations (UN). In 2005, GAO raised long-standing concerns that the ability of the UN's Office of Internal Oversight Services (OIOS) to carry out its mandate was constrained in scope and authority, and in 2006, GAO found that funding arrangements impeded OIOS's ability to operate independently. The U.S. Mission to the UN also expressed concern that OIOS's independence is limited in that it cannot make final hiring decisions for senior staff. In response to such concerns, the UN General Assembly in 2006 created an Independent Audit Advisory Committee (IAAC). GAO was asked to examine actions taken to address (1) impediments to OIOS's ability to provide independent oversight and (2) staffing issues that may have hindered its performance. GAO assessed OIOS's independence based on internationally recognized auditing standards, analyzed OIOS and other UN documents and data, and interviewed agency officials."

There has been much activity in the measurement of the elastic electromagnetic proton and neutron form factors in the last decade, and the quality of the data has been greatly improved by performing double polarization experiments, in compar- ison with previous unpolarized data. Here we review the experimental data base in view of the new results for the proton, and neutron, obtained at MIT-Bates, MAMI, and JLab. The rapid evolution of phenomenological models triggered by these high-precision experiments will be discussed.

A conceptual design of a 100 MWe modular molten salt solar power tower plant has been developed which can provide capacity factors in the range of 35 to 75%. Compared to single tower plants, the modular design provides a higher degree of flexibility in achieving the desired customer's capacity factor and is obtained simply by adjusting the number of standard modules. Each module consists of a standard size heliostat field and receiver system, hence reengineering and associated unacceptable performance uncertainties due to scaling are eliminated. The modular approach with multiple towers also improves plant availability. Heliostat field components, receivers and towers are shop assembled allowing for high quality and minimal field assembly. A centralized thermal-storage system stores hot salt from the receivers, allowing nearly continuous power production, independent of solar energy collection, and improved parity with the grid. A molten salt steam generator converts the stored thermal energy into steam, which powers a steam turbine generator to produce electricity. This paper describes the conceptual design of the plant, the advantages of modularity, expected performance, pathways to cost reductions, and environmental impact.

This is the final technical report containing a summary of all findings with regard to the following objectives of the project: (1) To quantify and understand the effects of wildfire on carbon storage and the exchanges of energy, CO2, and water vapor in a chronosequence of ponderosa pine (disturbance gradient); (2) To investigate the effects of seasonal and interannual variation in climate on carbon storage and the exchanges of energy, CO2, and water vapor in mature conifer forests in two climate zones: mesic 40-yr old Douglas-fir and semi-arid 60-yr old ponderosa pine (climate gradient); (3) To reduce uncertainty in estimates of CO2 feedbacks to the atmosphere by providing an improved model formulation for existing biosphere-atmosphere models; and (4) To provide high quality data for AmeriFlux and the NACP on micrometeorology, meteorology, and biology of these systems. Objective (1): A study integrating satellite remote sensing, AmeriFlux data, and field surveys in a simulation modeling framework estimated that the pyrogenic carbon emissions, tree mortality, and net carbon exchange associated with four large wildfires that burned ~50,000 hectares in 2002-2003 were equivalent to 2.4% of Oregon statewide anthropogenic carbon emissions over the same two-year period. Most emissions were from the combustion of the …

Processes for the removal of residual sludge from SRS waste tanks have historically used solutions containing up to 0.9 M oxalic acid to dissolve the remaining material following sludge removal. The selection of this process was based on a comparison of a number of studies performed to evaluate the dissolution of residual sludge. In contrast, the dissolution of the actinide mass, which represents a very small fraction of the waste, has not been extensively studied. The Pu, Np, and Am in the sludge is reported to be present as hydrated and crystalline oxides. To identify aqueous solutions which have the potential to increase the solubility of the actinides, the alkaline and mildly acidic test solutions shown below were selected as candidates for use in a series of solubility experiments. The efficiency of the solutions in solubilizing the actinides was evaluated using a simulated sludge prepared by neutralizing a HNO{sub 3} solution containing Pu, Np, and Am. The hydroxide concentration was adjusted to a 1.2 M excess and the solids were allowed to age for several weeks prior to starting the experiments. The sludge was washed with 0.01 M NaOH to prepare the solids for use. Following the addition of an …

This technical report contains recommendations from the Analytical Development (AD) organization of the Savannah River National Laboratory (SRNL) for a system of triplicate Sodium Iodide (NaI) detectors to be used to monitor Cesium-137 ({sup 137}Cs) content of the Decontaminated Salt Solution (DSS) output of the Small Column Ion Exchange (SCIX) process. These detectors need to be gain stabilized with respect to temperature shifts since they will be installed on top of Tank 41 at the Savannah River Site (SRS). This will be accomplished using NaI crystals doped with the alpha-emitting isotope, Americium-241({sup 241}Am). Two energy regions of the detector output will be monitored using single-channel analyzers (SCAs), the {sup 137}Cs full-energy {gamma}-ray peak and the {sup 241}Am alpha peak. The count rate in the gamma peak region will be proportional to the {sup 137}Cs content in the DSS output. The constant rate of alpha decay in the NaI crystal will be monitored and used as feedback to adjust the high voltage supply to the detector in response to temperature variation. An analysis of theoretical {sup 137}Cs breakthrough curves was used to estimate the gamma activity expected in the DSS output during a single iteration of the process. Count rates arising …

A long, relativistic particle beam propagating in an overdense plasma is subject to the self-modulation instability. This instability is analyzed and the growth rate is calculated, including the phase relation. The phase velocity of the wake is shown to be significantly less than the beam velocity. These results indicate that the energy gain of a plasma accelerator driven by a self-modulated beam will be severely limited by dephasing. In the long-beam, strongly-coupled regime, dephasing is reached in a homogeneous plasma in less than four e-foldings, independent of beam-plasma parameters.

Dedicated experiments to study Deeply Virtual Compton Scattering (DVCS) and Deeply Virtual Meson Production (DVMP) have been carried out at Jefferson Lab. DVCS helicity--dependent and helicity--independent cross sections and beam spin asymmetries have been measured, as well as cross sections and asymmetries for the $\pi^0$, $\eta$, $\rho^0$, $\rho^+$, $\omega$ and $\phi$ for exclusive electroproduction. The data were taken in a wide kinematic range in $Q^2$=1--4.5 GeV$^2$, $x_B$=0.1--0.5, and $|t|$ up to 2 GeV$^2$. The presented results offer a unique opportunity to study the structure of the nucleon at the parton level as one has access to Bjorken $x_B$ and momentum transfer to the nucleon $t$ at the same time.

The U.S. Department of Energy (DOE), Office of River Protection (ORP), is responsible for the remediation and stabilization of the Hanford Site tank farms, including 53 million gallons of highly radioactive mixed wasted waste contained in 177 underground tanks. The plan calls for all waste retrieved from the tanks to be transferred to the Waste Treatment Plant (WTP). The WTP will consist of three primary facilities including pretreatment facilities for Low Activity Waste (LAW) to remove aluminum, chromium and other solids and radioisotopes that are undesirable in the High Level Waste (HLW) stream. Removal of aluminum from HLW sludge can be accomplished through continuous sludge leaching of the aluminum from the HLW sludge as sodium aluminate; however, this process will introduce a significant amount of sodium hydroxide into the waste stream and consequently will increase the volume of waste to be dispositioned. A sodium recovery process is needed to remove the sodium hydroxide and recycle it back to the aluminum dissolution process. The resulting LAW waste stream has a high concentration of aluminum and sodium and will require alternative immobilization methods. Five waste forms were evaluated for immobilization of LAW at Hanford after the sodium recovery process. The waste forms …

This project seeks to determine if (1) inorganic-based ion exchange materials or (2) electrochemical methods in ionic liquids can be exploited to provide effective Am and Cm separations. Specifically, we seek to understand the fundamental structural and chemical factors responsible for the selectivity of inorganic-based ion-exchange materials for actinide and lanthanide ions. Furthermore, we seek to determine whether ionic liquids can serve as the electrolyte that would enable formation of higher oxidation states of Am and other actinides. Experiments indicated that pH, presence of complexants and Am oxidation state exhibit significant influence on the uptake of actinides and lanthanides by layered sodium titanate and hybrid zirconium and tin phosphonate ion exchangers. The affinity of the ion exchangers increased with increasing pH. Greater selectivity among Ln(III) ions with sodium titanate materials occurs at a pH close to the isoelectric potential of the ion exchanger. The addition of DTPA decreased uptake of Am and Ln, whereas the addition of TPEN generally increases uptake of Am and Ln ions by sodium titanate. Testing confirmed two different methods for producing Am(IV) by oxidation of Am(III) in ionic liquids (ILs). Experimental results suggest that the unique coordination environment of ionic liquids inhibits the direct electrochemical …
