The Stockpile Stewardship Program (SSP) is a single, highly integrated technical program for maintaining the surety and reliability of the U.S. nuclear stockpile. The SSP uses past nuclear test data along with current and future non-nuclear test data, computational modeling and simulation, and experimental facilities to advance understanding of nuclear weapons. It includes stockpile surveillance, experimental research, development and engineering (D&E) programs, and an appropriately scaled production capability to support stockpile requirements. This integrated national program requires the continued use of current facilities and programs along with new experimental facilities and computational enhancements to support these programs. The Advanced Simulation and Computing Program (ASC) is a cornerstone of the SSP, providing simulation capabilities and computational resources to support the annual stockpile assessment and certification, to study advanced nuclear weapons design and manufacturing processes, to analyze accident scenarios and weapons aging, and to provide the tools to enable stockpile Life Extension Programs (LEPs) and the resolution of Significant Finding Investigations (SFIs). This requires a balanced resource, including technical staff, hardware, simulation software, and computer science solutions. In its first decade, the ASC strategy focused on demonstrating simulation capabilities of unprecedented scale in three spatial dimensions. In its second decade, ASC is …

A new aluminium complex bearing a dianionic phenylene-diamine based ligand has been synthesized and shown to catalyze the intramolecular hydroamination of various aminoalkenes.

A letter report issued by the Government Accountability Office with an abstract that begins "Cost growth and schedule delays are prevalent problems in acquiring defense weapon systems. Manufacturing systems has proven difficult, particularly as programs transition to production. In December 2008, the Department of Defense (DOD) issued an updated version of its acquisition policy that reflects earlier consideration of manufacturing risks. A joint defense and industry group developed manufacturing readiness levels (MRL) to support assessments of manufacturing risks. Use of MRLs on all weapon acquisition programs has been proposed. In response to a congressional request, this report assesses the manufacturing problems faced by DOD, how MRLs can address manufacturing problems, how MRLs compare to manufacturing best practices of leading commercial firms, and challenges and barriers to implementing MRLs at DOD. In conducting our work, we contacted DOD, military services, and contractors; held interviews with leading commercial firms; reviewed program documents and policy proposals; and spoke with manufacturing experts."

Testimony issued by the Government Accountability Office with an abstract that begins "As consumer debt has risen to historic levels, a growing number of for-profit debt settlement companies have emerged. These companies say they will negotiate with consumers' creditors to accept a lump sum settlement for 40 to 60 cents on the dollar for amounts owed on credit cards and other unsecured debt. However, there have been allegations that some debt settlement companies engage in fraudulent, abusive, or deceptive practices that leave consumers in worse financial condition. For example, it has been alleged that they commonly charge fees in advance of settling debts or without providing any services at all, a practice on which the Federal Trade Commission (FTC) recently announced a proposed ban due to its harm to consumers. The Committee asked for an investigation of these issues. As a result, GAO attempted to (1) determine through covert testing whether these allegations are accurate; and, if so, (2) determine whether they are widespread, citing specific closed cases. To achieve these objectives, GAO conducted covert testing by calling 20 companies while posing as fictitious consumers; made overt, unannounced site visits to several companies called; interviewed industry stakeholders; and reviewed information …

In this study, a hydrodynamic model based on the unstructured-grid finite volume coastal ocean model (FVCOM) was developed for Bellingham Bay, Washington. The model simulates water surface elevation, velocity, temperature, and salinity in a three-dimensional domain that covers the entire Bellingham Bay and adjacent water bodies, including Lummi Bay, Samish Bay, Padilla Bay, and Rosario Strait. The model was developed using Pacific Northwest National Laboratory’s high-resolution Puget Sound and Northwest Straits circulation and transport model. A sub-model grid for Bellingham Bay and adjacent coastal waters was extracted from the Puget Sound model and refined in Bellingham Bay using bathymetric light detection and ranging (LIDAR) and river channel cross-section data. The model uses tides, river inflows, and meteorological inputs to predict water surface elevations, currents, salinity, and temperature. A tidal open boundary condition was specified using standard National Oceanic and Atmospheric Administration (NOAA) predictions. Temperature and salinity open boundary conditions were specified based on observed data. Meteorological forcing (wind, solar radiation, and net surface heat flux) was obtained from NOAA real observations and National Center for Environmental Prediction North American Regional Analysis outputs. The model was run in parallel with 48 cores using a time step of 2.5 seconds. It took …

A novel electromagnetic solver with mesh refinement capability was implemented in Warp. The solver allows for calculations in 2-1/2 and 3 dimensions, includes the standard Yee stencil, and the Cole-Karkkainen stencil for lower numerical dispersion along the principal axes. Warp implementation of the Cole-Karkkainen stencil includes an extension to perfectly matched layers (PML) for absorption of waves, and is preserving the conservation property of charge conserving current deposition schemes, like the Buneman-Villanesor and Esirkepov methods. Warp's mesh refinement framework (originally developed for electrostatic calculations) was augmented to allow for electromagnetic capability, following the methodology presented in [1] extended to an arbitrary number of refinement levels. Other developments include a generalized particle injection method, internal conductors using stair-cased approximation, and subcycling of particle pushing. The solver runs in parallel using MPI message passing, with a choice at runtime of 1D, 2D and 3D domain decomposition, and is shown to scale linearly on a test problem up-to 32,768 CPUs. The novel solver was tested on the modeling of filamentation instability, fast ignition, ion beam induced plasma wake, and laser plasma acceleration.

A neutron source for neutron resonance spectroscopy (NRS) has been developed using high intensity, short pulse lasers. This measurement technique will allow for robust measurements of interior ion temperature of laser-shocked materials and provide insight into equation of state (EOS) measurements. The neutron generation technique uses protons accelerated by lasers off of Cu foils to create neutrons in LiF, through (p,n) reactions with {sup 7}Li and {sup 19}F. The distribution of the incident proton beam has been diagnosed using radiochromic film (RCF). This distribution is used as the input for a (p,n) neturon prediction code which is compared to experimentally measured neutron yields. From this calculation, a total fluence of 1.8 x 10{sup 9} neutrons is infered, which is shown to be a reasonable amount for NRS temperature measurement.

A letter report issued by the Government Accountability Office with an abstract that begins "The conference report accompanying the Consolidated Appropriations Act of 2010 directed GAO to assess the joint report of the (SEC) and the Commodity Futures Trading Commission (CFTC) on harmonization of their regulatory approaches. In October 2009, CFTC and SEC issued this report in response to the Department of the Treasury's recommendation that the two agencies assess conflicts in their rules and statutes with respect to similar financial instruments. GAO's objectives were to review (1) how CFTC and SEC identified and assessed harmonization opportunities, (2) the agencies' progress toward implementing the joint report's recommendations, and (3) additional steps the agencies could take to reduce inconsistencies and overlap in their oversight. To meet these objectives, GAO reviewed the joint report and related documentation, interviewed agency officials, and obtained and analyzed written comments on the report from market participants."

The Interagency Working Group on Climate Change and Health (iWGCCH) is an ad hoc group formed by participating federal agencies and organizations at the invitation of the National institute of Environmental Health Sciences (NIEHS), National Oceanic and Atmospheric Administration (NOAA), Centers for Disease Control and Prevention (CDC), and Environmental Protection Agency (EPA) following the January 2009 'Workshop on a Research Agenda for Managing the Health Risks of Climate Change, ' sponsored by the Institute of Medicine Roundtable on Environmental Health Sciences, research, and medicine. This report identifies gaps in knowledge of the consequences for human health of climate change, and suggests research to address them. The content, views, and perspectives presented in this report are solely those of the authors, and do not reflect the official views, policies, or implied endorsement of any of the individual participating federal agencies or organizations.

A series of bis(3-hydroxy-N-methyl-pyridin-2-one) ligands was synthesized, and their respective uranyl complexes were characterized by single crystal X-ray diffraction analyses. These structures were inspected for high-energy conformations and evaluated using a series of metrics to measure co-planarity of chelating moieties with each other and the uranyl coordination plane, as well as to measure coordinative crowding about the uranyl dication. Both very short (ethyl, 3,4-thiophene and o-phenylene) and very long ({alpha},{alpha}{prime}-m-xylene and 1,8-fluorene) linkers provide optimal ligand geometries about the uranyl cation, resulting in planar, unstrained molecular arrangements. The planarity of the rigid linkers also suggests there is a degree of pre-organization for a planar coordination mode that is ideal for uranyl-selective ligand design. Comparison of intramolecular N{sub amide}-O{sub phenolate} distances and {sup 1}H NMR chemical shifts of amide protons supports earlier results that short linkers provide the optimal geometry for intramolecular hydrogen bonding.

Second, in the context of U.S. economic sanctions imposed for national security and foreign policy reasons, it evaluates Iran's economic structure, strengths, and vulnerabilities and discusses issues and options for Congress.

Under this project we have developed methods that allow the reconstruction of past {sup 14}C levels of the surface waters of the subpolar North Pacific Ocean by measuring the {sup 14}C contents of archived salmon scales. The overall goal of this research was to reduce of the uncertainty in the uptake of fossil CO{sub 2} by the oceans and thereby improve the quantification of the global carbon cycle and to elucidate the fate of anthropogenic CO{sub 2}. Ocean General Circulation Models (OGCMs), with their three dimensional global spatial coverage and temporal modeling capabilities, provide the best route to accurately calculating the total uptake of CO{sub 2} by the oceans and, hence, to achieving the desired reduction in uncertainty. {sup 14}C has played, and continues to play, a central role in the validation of the OGCMs calculations, particularly with respect to those model components which govern the uptake of CO{sub 2} from the atmosphere and the transport of this carbon within the oceans. Under this project, we have developed time-series records of the {sup 14}C levels of the surface waters of three areas of the subpolar North Pacific Ocean. As the previously available data on the time-history of oceanic surface water …

Member states of the North Atlantic Treaty Organization (NATO) contribute to the activities of the alliance in several ways, the chief of which is through the deployment of their own armed forces, funded by their national budgets. Certain commonly conducted activities, however, are paid for out of three NATO-run budgets. These three accounts--the civil budget, the military budget, and the security investment program--are funded by individual contributions from the member states. This report discusses North Atlantic Treaty Organization (NATO) burdensharing in funding such operations.

IVery High Temperature Reactors (VHTR) utilize the TRISO microsphere as the fundamental fuel unit in the core. The TRISO microsphere (~ 1- mm diameter) is composed of a UO2 kernel surrounded by a porous pyrolytic graphite buffer, an inner pyrolytic graphite layer, a silicon carbide (SiC) coating, and an outer pyrolytic graphite layer. The U-235 enrichment of the fuel is expected to range from 4% – 10% (higher enrichments are also being considered). The layer/coating system that surrounds the UO2 kernel acts as the containment and main barrier against the environmental release of radioactivity. To understand better the behavior of this fuel under in-core conditions (e.g., high temperature, intense fast neutron flux, etc.), the US Department of Energy (DOE) is launching a fuel testing program that will take place at the Advanced Test Reactor (ATR) located at Idaho National Laboratory (INL). During this project North Carolina State University (NCSU) researchers will collaborate with INL staff for establishing an optimized system for fuel monitoring for the ATR tests. In addition, it is expected that the developed system and methods will be of general use for fuel failure monitoring in gas cooled VHTRs.

Correspondence issued by the Government Accountability Office with an abstract that begins "The Securities and Exchange Commission's (SEC) primary mission is to protect investors and maintain the integrity of securities markets. As a part of its responsibility to protect investors, SEC seeks to ensure that individuals who violate federal securities laws and regulations take responsibility for their misdeeds. Specifically, when individuals or firms are found to have violated securities laws, SEC may order civil monetary penalties and seek ill-gotten financial gains, or disgorgement, from the violators. For its enforcement actions to be successful, SEC must have a collection and distribution program for both civil monetary penalties and disgorgement that functions effectively. In 2002, Congress passed the Sarbanes-Oxley Act to address corporate malfeasance and restore investor confidence in the U.S. securities markets. This legislation established numerous reforms to increase investor protection, including Section 308(a), the Federal Account for Investor Restitution provision, commonly known as the Fair Fund provision. This provision allows SEC to combine civil monetary penalties and other donations to disgorgement funds for the benefit of investors who suffer losses resulting from fraud or other securities violations. Fair Funds may be created through either SEC administrative proceedings or litigation in …

A TRACE/PARCS input model has been developed in order to be able to analyze anticipated transients without scram (ATWS) in a boiling water reactor. The model is based on one developed previously for the Browns Ferry reactor for doing loss-of-coolant accident analysis. This model was updated by adding the control systems needed for ATWS and a core model using PARCS. The control systems were based on models previously developed for the TRAC-B code. The PARCS model is based on information (e.g., exposure and moderator density (void) history distributions) obtained from General Electric Hitachi and cross sections for GE14 fuel obtained from an independent source. The model is able to calculate an ATWS, initiated by the closure of main steam isolation valves, with recirculation pump trip, water level control, injection of borated water from the standby liquid control system and actuation of the automatic depres-surization system. The model is not considered complete and recommendations are made on how it should be improved.
