The Millennium Development Goals: The September 2010 U.N. High-level Meeting

This report discusses overarching trends in Millennium Development Goals (MDG) progress and lessons learned from previous and ongoing efforts to achieve them. The MDGs are a group of measurable development targets agreed to by 189 U.N. member states - including the United States - as part of the 2000 Millennium Declaration. The MDGs cover a number of issues, such as eradicating extreme hunger and poverty, combating HIV/AIDS, and promoting gender equality and women's empowerment. This report examines U.S. policy toward the MDGs and how, if at all, the Goals fit into U.S. development and foreign assistance policy. It also examines different schools of thought regarding the effectiveness of the Goals, their role in international development, and their long-term sustainability. This report addresses the MDGs as a whole; it does not assess or analyze issues pertaining to the individual Goals.

Summary Report: Glass-Ceramic Waste Forms for Combined Fission Products (open access)

Summary Report: Glass-Ceramic Waste Forms for Combined Fission Products

Glass-ceramic waste form development began in FY 2010 examining two combined waste stream options: (1) alkaline earth (CS) + lanthanide (Ln), and (2) + transition metal (TM) fission-product waste streams generated by the uranium extraction (UREX+) separations process. Glass-ceramics were successfully developed for both options however; Option 2 was selected over Option 1, at the conclusion of 2010, because Option 2 immobilized all three waste streams with only a minimal decrease in waste loading. During the first year, a series of three glass (Option 2) were fabricated that varied waste loading-WL (42, 45, and 50 mass%) at fixed molar ratios of CaO/MoO{sub 3} and B{sub 2}O{sub 3}/alkali both at 1.75. These glass-ceramics were slow cooled and characterized in terms of phase assemblage and preliminary irradiation stability. This fiscal year, further characterization was performed on the FY 2010 Option 2 glass-ceramics in terms of: static leach testing, phase analysis by transmission electron microscopy (TEM), and irradiation stability (electron and ion). Also, a new series of glass-ceramics were developed for Option 2 that varied the additives: Al{sub 2}O{sub 3} (0-6 mass%), molar ratio of CaO/MoO{sub 3} and B{sub 2}O{sub 3}/alkali (1.75 to 2.25) and waste loading (50, 55, and 60 mass%).

Glass Ceramic Waste Forms for Combined CS+LN+TM Fission Products Waste Streams (open access)

Glass Ceramic Waste Forms for Combined CS+LN+TM Fission Products Waste Streams

In this study, glass ceramics were explored as an alternative waste form for glass, the current baseline, to be used for immobilizing alkaline/alkaline earth + lanthanide (CS+LN) or CS+LN+transition metal (TM) fission-product waste streams generated by a uranium extraction (UREX+) aqueous separations type process. Results from past work on a glass waste form for the combined CS+LN waste streams showed that as waste loading increased, large fractions of crystalline phases precipitated upon slow cooling.[1] The crystalline phases had no noticeable impact on the waste form performance by the 7-day product consistency test (PCT). These results point towards the development of a glass ceramic waste form for treating CS+LN or CS+LN+TM combined waste streams. Three main benefits for exploring glass ceramics are: (1) Glass ceramics offer increased solubility of troublesome components in crystalline phases as compared to glass, leading to increased waste loading; (2) The crystalline network formed in the glass ceramic results in higher heat tolerance than glass; and (3) These glass ceramics are designed to be processed by the same melter technology as the current baseline glass waste form. It will only require adding controlled canister cooling for crystallization into a glass ceramic waste form. Highly annealed waste form …

Optimizing Laser-Accelerated Ion Beams for a Collimated Neutron Source (open access)

Optimizing Laser-Accelerated Ion Beams for a Collimated Neutron Source

High-flux neutrons for imaging and materials analysis applications have typically been provided by accelerator- and reactor-based neutron sources. A novel approach is to use ultraintense (>1018W/cm2) lasers to generate picosecond, collimated neutrons from a dual target configuration. In this article, the production capabilities of present and upcoming laser facilities are estimated while independently maximizing neutron yields and minimizing beam divergence. A Monte-Carlo code calculates angular and energy distributions of neutrons generated by D-D fusion events occurring within a deuterated target for a given incident beam of D+ ions. Tailoring of the incident distribution via laser parameters and microlens focusing modifies the emerging neutrons. Projected neutron yields and distributions are compared to conventional sources, yielding comparable on-target fluxes per discharge, shorter time resolution, larger neutron energies and greater collimation.

Long-Term Testing of Rhodium-Based Catalysts for Mixed Alcohol Synthesis – 2013 Progress Report (open access)

Long-Term Testing of Rhodium-Based Catalysts for Mixed Alcohol Synthesis – 2013 Progress Report

The U.S. Department of Energy’s Pacific Northwest National Laboratory has been conducting research since 2005 to develop a catalyst for the conversion of synthesis gas (carbon monoxide and hydrogen) into mixed alcohols for use in liquid transportation fuels. Initially, research involved screening possible catalysts based on a review of the literature, because at that time, there were no commercial catalysts available. The screening effort resulted in a decision to focus on catalysts containing rhodium and manganese. Subsequent research identified iridium as a key promoter for this catalyst system. Since then, research has continued to improve rhodium/manganese/iridium-based catalysts, optimizing the relative and total concentrations of the three metals, examining baseline catalysts on alternative supports, and examining effects of additional promoters. Testing was continued in FY 2013 to evaluate the performance and long-term stability of the best catalysts tested to date. Three tests were conducted. A long-term test of over 2300 hr duration at a single set of operating conditions was conducted with the best carbon-supported catalyst. A second test of about 650 hr duration at a single set of operating conditions was performed for comparison using the same catalyst formulation on an alternative carbon support. A third test of about 680 …

War Powers Resolution: Presidential Compliance

Two separate but closely related issues confront Congress each time the President introduces armed forces into a situation abroad that conceivably could lead to their involvement in hostilities. One issue concerns the division of war powers between the President and Congress, whether the use of armed forces falls within the purview of the congressional power to declare war and the War Powers Resolution. The other issue is whether or not Congress concurs in the wisdom of the action. A longer-term issue is whether the War Powers Resolution is an appropriate and effective means of assuring congressional participation in actions that might get the United States involved in war.

NANA Wind Resource Assessment Program Final Report (open access)

NANA Wind Resource Assessment Program Final Report

NANA Regional Corporation (NRC) of northwest Alaska is located in an area with abundant wind energy resources. In 2007, NRC was awarded grant DE-FG36-07GO17076 by the US Department of Energy's Tribal Energy Program for funding a Wind Resource Assessment Project (WRAP) for the NANA region. The NANA region, including Kotzebue Electric Association (KEA) and Alaska Village Electric Cooperative (AVEC) have been national leaders at developing, designing, building, and operating wind-diesel hybrid systems in Kotzebue (starting in 1996) and Selawik (2002). Promising sites for the development of new wind energy projects in the region have been identified by the WRAP, including Buckland, Deering, and the Kivalina/Red Dog Mine Port Area. Ambler, Shungnak, Kobuk, Kiana, Noorvik & Noatak were determined to have poor wind resources at sites in or very near each community. However, all five of these communities may have better wind resources atop hills or at sites with slightly higher elevations several miles away.

Engineering-Scale Demonstration of DuraLith and Ceramicrete Waste Forms

To support the selection of a waste form for the liquid secondary wastes from the Hanford Waste Immobilization and Treatment Plant, Washington River Protection Solutions (WRPS) has initiated secondary waste form testing on four candidate waste forms. Two of the candidate waste forms have not been developed to scale as the more mature waste forms. This work describes engineering-scale demonstrations conducted on Ceramicrete and DuraLith candidate waste forms. Both candidate waste forms were successfully demonstrated at an engineering scale. A preliminary conceptual design could be prepared for full-scale production of the candidate waste forms. However, both waste forms are still too immature to support a detailed design. Formulations for each candidate waste form need to be developed so that the material has a longer working time after mixing the liquid and solid constituents together. Formulations optimized based on previous lab studies did not have sufficient working time to support large-scale testing. The engineering-scale testing was successfully completed using modified formulations. Further lab development and parametric studies are needed to optimize formulations with adequate working time and assess the effects of changes in raw materials and process parameters on the final product performance. Studies on effects of mixing intensity on the …

Broadband Internet Access and the Digital Divide: Federal Assistance Programs

Some policymakers, believing that disparities in broadband access across American society could have adverse economic and social consequences on those left behind, assert that the federal government should play a more active role to avoid a "digital divide" in broadband access. One approach is for the federal government to provide financial assistance to support broadband deployment in underserved areas. Others, however, believe that federal assistance for broadband deployment is not appropriate. Some opponents question the reality of the "digital divide," and argue that federal intervention in the broadband marketplace would be premature and, in some cases, counterproductive.

China's Sovereign Wealth Fund: Developments and Policy Implications (open access)

China's Sovereign Wealth Fund: Developments and Policy Implications

China's ruling executive body, the State Council, established the China Investment Corporation (CIC), a sovereign wealth fund, in September 2007 to invest $200 billion of China's then $1.4 trillion in foreign exchange reserves. Congress and financial analysts raised concerns about the CIC after its creation, partly because it was a comparatively large sovereign wealth fund, partly because it was government-owned, and partly because it reported directly to the State Council. These concerns raise question about U.S. policies on inward foreign direct investment (FDI) and the global competitiveness of U.S. financial institutions. Certain commentators suggest that more should be done to protect the United States from China's rising role in international capital markets.

The Experimental Program to Stimulate Competitive Research (EPSCoR) of the National Science Foundation (NSF) was authorized by Congress in 1978, partly in response to concerns in Congress and the concerns of some in academia and the scientific community about the geographic distribution of federal research and development (R&D) funds. Some have questioned the length of time states should receive EPSCoR support. It continues to be called an experimental program after 28 years, and observers have noted that no state has yet to graduate, or leave the program.
