The Savannah River Site has areas where soil is contaminated with metals and/or radionuclides. Many of these areas are surrounded by native vegetation which is growing adjacent to the area and where the roots have penetrated into the contaminated soil of the area. In some cases vegetation has actually invaded the contaminated area. Even though the volume of contaminated vegetation is small, there are problems associated with its disposal. Vegetation decomposes quickly after burial and the volume of buried vegetation can decrease. The voids left can lead to subsidence and possible failure of the clay cap constructed over hazardous and/or radioactive waste burial grounds. An alternative to burying the wood is to burn it and bury the ash. However, burning will introduce the contamination in the vegetation into the air where there is potential for inhalation of the contaminants. A procedure is described to assess the hazard associated with inhalation of contamination from burning of vegetation growing in contaminated soil. The procedure is applied to evaluation of the consequence of burning vegetation grown adjacent to and in the SRL Seepage Basins. The results indicate that burning the vegetation during the day could introduce a level of contaminants to the atmosphere …

Experimental data is being obtained from operating a high temperature heat pump system. The use of methanol as a working fluid will necessitate careful monitoring of refrigerant temperatures and pressures with chemical analysis performed on the working fluid during scheduled down time. Materials sent to vendors by Auburn University and quotes received by Auburn concerning equipment (compressor, evaporator, condensor, air heater, dryer, two accumulator tanks, and three expansion valves) are discussed. The simulated dryer and two accumulator tanks were designed by Auburn. The detailed design and pricing estimates are included. Additional information is presented on layout and construction; start-up; testing; shut down; scheduled maintenance and inspection; safety precautions; control system; and trouble shooting.

This report looks at the background and current Congressional status of the Terrorism Risk Insurance Act of 2002.

A letter report issued by the Government Accountability Office with an abstract that begins "Increases in the number and intensity of wildland fires have led the Department of Agriculture's Forest Service to place greater emphasis on thinning forests and rangelands to reduce the buildup of potentially hazardous vegetation that can fuel wildland fires. The public generally has an opportunity to challenge agency hazardous fuel reduction decisions with which it disagrees. Depending on the type of project being undertaken, the public can file a formal objection to a proposed decision, or can appeal a decision the agency has already made. Appeals and objections must be reviewed by the Forest Service within prescribed time frames. Final decisions may also generally be challenged in federal court. GAO was asked, among other things, to determine, for fiscal years 2006-2008, (1) the number of Forest Service fuel reduction decisions and the associated acreage; (2) the number of decisions subject to appeal and objection, the number appealed, objected to, and litigated, and the associated acreage; and (3) the outcomes of appeals, objections, and litigation, and the extent to which appeals and objections were processed within prescribed time frames. In doing so, GAO conducted a nationwide survey …

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2001, the National Archives and Records Administration (NARA) has been working to develop an Electronic Records Archive (ERA) to preserve and provide access to massive volumes of all types of electronic records. NARA originally planned to complete the system in 2012, but has repeatedly revised the program schedule and estimated cost and is now planning to deploy an ERA system with reduced functionality by the end of fiscal year 2011. As required by the Consolidated Appropriations Act, 2010, and the Continuing Appropriations Act, 2011, NARA submitted an expenditure plan to Congress to support its request for fiscal year 2011 ERA funding. The legislation also requires that this plan meet six conditions, including review by GAO. GAO's objectives in reviewing the fiscal year 2011 plan were to (1) determine whether the plan satisfies legislative conditions, (2) determine the extent to which NARA has implemented prior GAO recommendations, and (3) provide any other observations on the plan or the ERA acquisition. To do this, GAO reviewed the expenditure plan and other agency documents and interviewed NARA officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Since coins are more durable than notes and do not need replacement as often, many nations have replaced lower-denomination notes with coins to obtain a financial benefit. GAO has estimated the annual net benefit to the U.S. government of replacing the $1 note with a $1 coin four times over the past 20 years, most recently in April 2000. Asked to update its estimate, GAO (1) estimated the net benefit to the government of replacing the $1 note with a $1 coin and (2) examined other effects stakeholders suggested such a replacement could have. To perform its work, GAO constructed an economic model and interviewed officials from the Federal Reserve, the Treasury Department, the U.S. Secret Service, outside experts, and officials from Canada and the United Kingdom. To determine the effects on stakeholders, GAO interviewed officials from industries and organizations that might be affected by changes to currency."

A letter report issued by the Government Accountability Office with an abstract that begins "Federal and state trade promotion activities are intended to help U.S. firms compete successfully in foreign markets. Small and medium-sized enterprises (SME)--firms with fewer than 500 employees--represent a key segment of exporting firms. GAO was asked to determine (1) the relationship between the Department of Commerce's (Commerce) U.S. Commercial Service (CS) and states' trade offices' export promotion programs, (2) CS's methodology and practices for determining costs and establishing user fees for export promotion services, and (3) how CS's user fees affect SMEs' use of its programs. GAO conducted a survey of states' trade offices and reviewed data such as export promotion budgets and fees, program information, government standards, and user fee studies. GAO met with officials from Commerce, the State International Development Organizations, six states' trade offices, and others."

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency's (EPA) overarching mission is to protect human health and the environment by implementing and enforcing environmental laws intended to improve the quality of the nation's air and water and to protect its land. EPA's policies and programs affect virtually all segments of the economy, society, and government. As such, it operates in a highly complex and controversial regulatory arena. In recent years, GAO has identified several key challenges EPA faces and corrective actions that would enable the agency to more effectively accomplish its mission. GAO was asked to identify challenges at EPA that hinder its ability to implement its programs effectively, based on prior GAO work. These challenges include (1) improving agencywide management, (2) transforming EPA's processes for assessing and controlling toxic chemicals, (3) improving implementation of the Clean Air Act, (4) reducing pollution in the nation's waters, (5) speeding the pace of cleanup at Superfund and other hazardous waste sites, and (6) addressing emerging climate change issues."

A letter report issued by the Government Accountability Office with an abstract that begins "Of the 29 federal programs GAO reviewed (which accounted for about 86 percent of federal program spending for states or their residents in fiscal year 2010), statehood would likely affect 11 programs. For 3 other programs, while the programs themselves would likely not change under statehood, eligibility determinations for these programs could be affected indirectly by changes that could occur to benefits in other programs. Statehood would not likely affect the 15 remaining programs. See figure below."

A letter report issued by the Government Accountability Office with an abstract that begins "In 1995, the United States banned exports to Iran of most U.S. goods without a Treasury Department license. In 2008, the U.S. media, citing U.S. government statistics, reported that U.S. firms were exporting numerous goods to Iran. The statistics are maintained by the Census Bureau and are based on data filed by exporters or their agents. The United States has also generally banned unlicensed transshipments of U.S. goods to Iran via other nations. In this report, GAO assesses the extent to which (1) U.S. trade statistics accurately depict exports to Iran, (2) Treasury licenses exports to Iran in accordance with the trade restrictions and provides licensing data to enforcement agencies and Congress, and (3) Iran obtains U.S. military and dual-use goods through transshipment. GAO analyzed Census export data, a randomly selected sample of Treasury export licenses, Treasury licensing information systems, and U.S. government transshipment data. It also interviewed relevant U.S. government officials."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed and updated its previous work on airfares and service and reexamined the effect that certain barriers have had on these measures, focusing on: (1) how airfares have changed since 1990 for travel to and from 171 airports serving various U.S. communities; (2) how the quality of air service has changed since 1978 for travel to and from these airports; and (3) the extent to which certain barriers to entry--restrictive gate-leasing arrangements, controls on the number of allowable takeoffs and landings at some airports, and the limits on the distance that flights from some airports can be--influence competition at affected airports."

In July 2008, a new temporary unemployment benefit, the Emergency Unemployment Compensation (EUC08) program, began. The most recent legislation, P.L. 111-205, extended the authorization of the EUC08 program, but did not change the structure of the program or augment benefits. This temporary unemployment insurance program provides up to 20 additional weeks of unemployment benefits to certain workers who have exhausted their rights to regular unemployment compensation (UC) benefits. This report discusses the various tiers of the EUC08 program, as well as related legislation. This report will be updated to reflect current congressional action or programmatic changes.

Uruguay is in the midst of making critical decisions affecting the design of its future energy supply system. Momentum for change is expected to come from several directions, including recent and foreseeable upgrades and modifications to energy conversion facilities, the importation of natural gas from Argentina, the possibility for a stronger interconnection of regional electricity systems, the country's membership in MERCOSUR, and the potential for energy sector reforms by the Government of Uruguay. The objective of this study is to analyze the effects of several fuel diversification strategies on Uruguay's energy supply system. The analysis pays special attention to fuel substitution trends due to potential imports of natural gas via a gas pipeline from Argentina and increasing electricity ties with neighboring countries. The Government of Uruguay has contracted with Argonne National Laboratory (ANL) to study several energy development scenarios with the support of several Uruguayan institutions. Specifically, ANL was asked to conduct a detailed energy supply and demand analysis, develop energy demand projections based on an analysis of past energy demand patterns with support from local institutions, evaluate the effects of potential natural gas imports and electricity exchanges, and determine the market penetration of natural gas under various scenarios.

This is a complete (Fiscal Years 2000–2006) collection of the Idaho National Laboratory’s (INL) research and development contributions to the project, “CO2 Separation Using Thermally Optimized Membranes.” The INL scientific contribution to the project has varied due to the fluctuations in funding from year to year. The focus of the project was polybenzimidazole (PBI) membranes and developing PBI compounds (both substitution and blends) that provide good film formation and gas separation membranes. The underlying problem with PBI is its poor solubility in common solvents. Typically, PBI is dissolved in “aggressive” solvents, like N,N-dimethylacetamide (DMAc) and N methylpyrrolidone (NMP). The INL FY-03 research was directed toward making soluble N-substituted PBI polymers, where INL was very successful. Many different types of modified PBI polymers were synthesized; however, film formation proved to be a big problem with both unsubstituted and N-substituted PBIs. Therefore, INL researchers directed their attention to using plasticizers or additives to make the membranes more stable and workable. During the course of these studies, other high-performance polymers (like polyamides and polyimides) were found to be better materials, which could be used either by themselves or blends with PBI. These alternative high-performance polymers provided the best pathway forward for soluble high-temperature …

The processes of crystallization and solid deposit formation that led to the shutdown of the 2H evaporator operation at the Savannah River Site (SRS) and that could possibly cause similar problems in the future or in other evaporators need to be better understood. Through experimentation, thermodynamic modeling, and correlation of scaling to historical tank farm operations, progress has been made in developing guidelines as to the concentrations of silicon and aluminum that can be processed by evaporators while avoiding unacceptable levels of scale formation. However, because of limitations of the thermodynamic model and an insufficient amount of operational data at slightly supersaturated concentration levels, uncertainty still exists regarding acceptable feed concentrations. The objective of this effort is to provide information that can be used in defining acceptable levels of silicon and aluminum in evaporator feed solutions. Data collected previously showed that particle formation reactions can be rapid at evaporator temperatures for elevated silicon and aluminum concentrations. However, insufficient data exists to estimate the silicon and aluminum concentrations above which solids will form in the time frame of evaporator processing. The work described in this report was designed to determine the induction period for solutions of decreasing aluminum and silicon concentration …

The objective of this project is to develop dense ceramic membranes that, without using an external power supply or circuitry, can produce hydrogen via coal/coal gas-assisted water dissociation. This project grew out of an effort to develop a dense ceramic membrane for separating hydrogen from gas mixtures such as those generated during coal gasification, methane partial oxidation, and water-gas shift reactions [1]. That effort led to the development of various cermet (i.e., ceramic/metal composite) membranes that enable hydrogen to be produced by two methods. In one method, a hydrogen transport membrane (HTM) selectively removes hydrogen from a gas mixture by transporting it through either a mixed protonic/electronic conductor or a hydrogen transport metal. In the other method, an oxygen transport membrane (OTM) generates hydrogen mixed with steam by removing oxygen that is generated through water splitting [1, 2]. This project focuses on the development of OTMs that efficiently produce hydrogen via the dissociation of water. Supercritical boilers offer very high-pressure steam that can be decomposed to provide pure hydrogen by means of OTMs. Oxygen resulting from the dissociation of steam can be used for coal gasification, enriched combustion, or synthesis gas production. Hydrogen and sequestration-ready CO{sub 2} can be produced …

The effect on mathematics of collaborations between high-energy theoretical physics and modern mathematics has been remarkable. Mirror symmetry has revolutionized enumerative geometry, and Seiberg-Witten invariants have greatly simplified the study of four manifolds. And because of their application to string theory, physicists now need to know cohomology theory, characteristic classes, index theory, K-theory, algebraic geometry, differential geometry, and non-commutative geometry. Much more is coming. We are experiencing a deeper contact between the two sciences, which will stimulate new mathematics essential to the physicists’ quest for the unification of quantum mechanics and relativity. Our grant, supported by the Department of Energy for twelve years, has been instrumental in promoting an effective interaction between geometry and string theory, by supporting the Mathematical Physics seminar, postdoc research, collaborations, graduate students and several research papers.
