The Idaho Chemical Processing Plant for several years has been studying various pulsing systems, used in extraction columns for processing irradiated nucIear fuel elements, in an effort to eliminate the mechanical difficuittes in present pulsing systems. An air puising system has been demonstrated, and a discussion is given of experimental work, pulser design, and plant operational experience with this system. It is concluded, from work completed thus far that air puising of extraction columns is a considerable improvement over other systems. (auth)

The effect of transverse displacements of combined function magnets is investigated where the disperion in not matched due to roll. This dispersion function is perturbed by displacement of combined function magnets either singly or coherently. In the latter case the effect of a systematic (or DC) offset of magnets is examined. This type of error can occur due to systematics in the placement or the readout of Beam Position Monitors or equivalently by correcting the orbit of a beam of the wrong momentum with respect to the Arc magnet excitation. 5 refs., 18 figs.

We propose to study the utilization of high-temperature (approximately 2000-2500K) process heat from fusion reactors for large-scale chemical process applications. Of particular interest is the decomposition reaction, CO/sub 2/ ..-->.. CO + /sup 1///sub 2/O/sub 2/, which at 2500K should yield approximately 60 percent conversion to CO if O/sub 2/ is partially removed through an oxide membrane. Hydrogen can be derived from CO at lower temperatures by reacting CO with steam, and C can also be derived from CO by a disproportionation into C and CO/sub 2/ at approximately 1000K. These chemicals, CO, H/sub 2/, and C, form the basis for a multitude of non-electrical energy applications in the areas of transportation, industrial processes, and residential and commercial uses. In addition to the CO/sub 2/ decomposition process, we propose to explore a variety of ideas and evaluate them for scientific and economic merit. A follow-on research and development program will be proposed if the ideas prove promising.

The combined efforts of the food industry and the regulatory agencies often are credited with making the U.S. food supply among the safest in the world. Nonetheless, many food-related health issues persist. At issue is whether the current U.S. regulatory system has the resources and structural organization to protect consumers from these dangers. Also at issue is whether the federal food safety laws themselves, first enacted in the early 1900s, have kept pace with the significant changes that have occurred in the food production, processing, and marketing sectors since then.

A letter report issued by the Government Accountability Office with an abstract that begins "The Trade Adjustment Assistance (TAA) Reform Act of 2002 consolidated two programs serving trade-affected workers and made changes to expand benefits and decrease the time it takes for workers to get services. GAO was asked to provide information on (1) how key reform provisions have affected program services, (2) what have been the challenges in implementing new provisions, (3) whether demand for TAA training has changed and how states are meeting this demand, and (4) what is known about what the TAA program is achieving."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2008, the Department of Treasury (Treasury) plans to spend approximately $3 billion on information technology (IT) investments--the third largest planned IT expenditure among civilian agencies. To more effectively manage such investments, in 2005 the Office of Management and Budget required agencies to use earned value management (EVM). EVM is a project management approach that, if implemented appropriately, provides objective reports of project status, produces early warning signs of impending schedule delays and cost overruns, and provides unbiased estimates of a program's total costs. GAO was asked to assess whether the department and its key component agencies (1) have the policies in place to effectively implement EVM and (2) are adequately using EVM techniques to manage critical system investments. GAO compared agency policies to best practices identified in the Cost Assessment Guide and reviewed the implementation of key EVM practices for several investments."

This report provides an overview of health care services and disability compensation benefits available to Vietnam veterans, Children of Vietnam Era veterans, and non-Vietnam veterans exposed to herbicides. This is followed by a discussion of litigation pertaining to Navy veterans of the Vietnam Era who served offshore and were never physically present on Vietnamese soil. The report concludes with a discussion of epidemiologic research conducted to study the health effects of Agent Orange and dioxin exposure on Vietnam veterans.

A letter report issued by the Government Accountability Office with an abstract that begins "The Transportation Security Administration (TSA), in the Department of Homeland Security (DHS), is committed to sharing information with public transit agencies. The Implementing Recommendations of the 9/11 Commission Act directed GAO to report on public transit information sharing. This report describes (1) the primary mechanisms used to share security information with public transit agencies; and evaluates (2) public transit agencies' satisfaction with federal efforts to share security-related information (e.g., security threats) and opportunities to improve these efforts; and (3) the extent to which DHS has identified goals and measures for sharing information. GAO surveyed 96 of the 694 U.S. public transit agencies based on 2008 ridership and received 80 responses. The 96 public transit agencies surveyed represent about 91 percent of total 2008 ridership. GAO also reviewed documents, such as DHS's Information Sharing Strategy, and interviewed agency officials."

Supporters of comprehensive immigration reform have urged the President and Congress to pursue reform legislation. While legislative action on comprehensive reform does not appear likely during the remainder of the 111th Congress, there may be an effort to enact a measure, commonly referred to as the "DREAM Act," to enable certain unauthorized alien students to legalize their status. Multiple bills have been introduced in recent Congresses to address the unauthorized student population. This report discusses the DREAM Act, the topic of unauthorized alien students in general, and other related legislation.

A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, Congress passed the Credit Rating Agency Reform Act (Act), which intended to improve credit ratings by fostering accountability, transparency, and competition. The Act established Securities and Exchange Commission (SEC) oversight over Nationally Recognized Statistical Rating Organizations (NRSRO), which are credit rating agencies that are registered with SEC. The Act requires GAO to review the implementation of the Act. This report (1) discusses the Act's implementation; (2) evaluates NRSROs' performance-related disclosures; (3) evaluates removing NRSRO references from certain SEC rules; (4) evaluates the impact of the Act on competition; and (5) provides a framework for evaluating alternative models for compensating NRSROs. To address the mandate, GAO reviewed SEC rules, examination guidance, completed examinations, and staff memoranda; analyzed required NRSRO disclosures and market share data; and interviewed SEC and NRSRO officials and market participants."

A letter report issued by the Government Accountability Office with an abstract that begins "The marine transportation system is a critical part of the nation's infrastructure. To facilitate the safety and efficiency of this system, the Coast Guard maintains aids-to-navigation (ATON), such as buoys and beacons, and conducts domestic icebreaking in the Great Lakes, St. Lawrence Seaway, and northeast coast. To conduct these missions, the Coast Guard has a fleet of more than 200 vessels, ranging from 225-foot seagoing buoy tenders and 140-foot domestic icebreakers to 21-foot boats. After the terrorist attacks of September 11, 2001, many of these assets took on additional responsibilities for security patrols and other homeland security duties. Although some assets have been recently acquired, many others are reaching or have exceeded their design service lives, raising concerns about how well and for how much longer these older assets may be able to carry out their missions. In response, GAO examined (1) recent trends in the amount of time these assets have spent performing missions; (2) asset condition and its effect on mission performance; and (3) the actions taken by the Coast Guard to continue to achieve the missions of these assets. To conduct this work, …

A letter report issued by the Government Accountability Office with an abstract that begins "The high pace of military operations, thousands of casualties in ongoing military operations, and the services' recruiting challenges have raised questions about who is serving in today's military and concern that certain subgroups of the U.S. population may be disproportionately represented among those fighting and dying in support of the war on terrorism. These challenges and concerns have increased the need for information on the demographic characteristics of military personnel. GAO was asked to address three questions: (1) What are the demographic characteristics of servicemembers and how do they compare to the comparable U.S. civilian workforce? (2) How well are the services meeting their overall recruitment goals, and what influences whether or not individuals join the military? (3) What are the demographic characteristics of servicemembers who remained in the military in fiscal years 2000, 2002, and 2004? GAO was also asked to examine the demographic characteristics of servicemembers who died or were wounded in combat in Operations Iraqi Freedom and Enduring Freedom."

A letter report issued by the Government Accountability Office with an abstract that begins "The Empowerment Zone/Enterprise Community (EZ/EC) program is one of the most recent large-scale federal effort intended to revitalize impoverished urban and rural communities. There have been three rounds of EZs and two rounds of ECs, all of which are scheduled to end no later than December 2009. The Community Renewal Tax Relief Act of 2000 mandated that GAO audit and report in 2004, 2007, and 2010 on the EZ/EC program and its effect on poverty, unemployment, and economic growth. This report, which focuses on the first round of the program starting in 1994, discusses program implementation; program oversight; data available on the use of program tax benefits; and the program's effect on poverty, unemployment, and economic growth. In conducting this work, GAO made site visits to all Round I EZs, conducted an e-mail survey of 60 Round I ECs, and used several statistical methods to analyze program effects."

A letter report issued by the Government Accountability Office with an abstract that begins "The National Wildlife Refuge System, which is administered by the Fish and Wildlife Service in the Department of the Interior, comprises 585 refuges on more than 96 million acres of land and water that preserve habitat for waterfowl and other migratory birds, threatened and endangered species, and other wildlife. Refuges also provide wildlife-related activities such as hunting and fishing to nearly 40 million visitors every year. GAO was asked to (1) describe changing factors that the refuge system experienced from fiscal years 2002 through 2007, including funding and staffing changes, and (2) examine how habitat management and visitor services changed during this period. We surveyed all refuges; visited 19 refuges in 4 regions; and interviewed refuge, regional, and national officials. In commenting on a draft of this report, the Department of the Interior made technical comments that we have incorporated as appropriate. GAO is not making recommendations in this report."

A letter report issued by the Government Accountability Office with an abstract that begins "The Air Force has turned to service contracts for the F-15C, F-16, Airborne Warning and Control System, and F-15E, and the Army has done the same for helicopter simulator training at its Flight School XXI. The contractors own, operate, and maintain the simulator hardware and software. The military services rely on industry to capitalize the required up-front investment, with the understanding that the contractors will amortize this investment by selling training services by the hour. GAO was asked to address (1) the factors that led the Air Force and Army to acquire simulator training as a service and whether the decision to use this approach was adequately supported; (2) whether implementation of the approach has resulted in the planned number of simulator training sites being activated; and (3) whether the Air Force and Army are effectively tracking the return on their expenditure of taxpayer dollars. GAO makes recommendations to the Secretary of Defense intended to improve management and oversight of these service contracts to help ensure that the best approach is used to provide the war-fighter with needed training. In written comments on a draft of …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security's (DHS) Secure Border Initiative (SBI) is a multiyear, multibillion-dollar program to secure the nation's borders through, among other things, new technology, increased staffing, and new fencing and barriers. The technology component of SBI, which is known as SBInet, involves the acquisition, development, integration, and deployment of surveillance systems and command, control, communications, and intelligence technologies. GAO was asked to determine whether DHS (1) has defined the scope and timing of SBInet capabilities and how these capabilities will be developed and deployed, (2) is effectively defining and managing SBInet requirements, and (3) is effectively managing SBInet testing. To do so, GAO reviewed key program documentation and interviewed program officials, analyzed a random sample of requirements, and observed operations of a pilot project."

A letter report issued by the Government Accountability Office with an abstract that begins "The federal government's reliance on leased space underscores the need to physically secure this space and help safeguard employees, visitors, and government assets. In April 2010 the Interagency Security Committee (ISC), comprised of 47 federal agencies and departments and chaired by the Department of Homeland Security (DHS), issued Physical Security Criteria for Federal Facilities (the 2010 standards) which supersede previous ISC standards. In response to Congress' direction to review ISC standards for leased space, this report (1) identifies challenges that exist in protecting leased space and (2) examines how the 2010 standards address these challenges. To conduct this work, GAO analyzed agency documents and interviewed federal officials from ISC, four federal departments selected as case studies based on their large square footage of leased space, and the Federal Protective Service (FPS). GAO also consulted prior work on federal real property and physical security, including key practices in facility protection."

A letter report issued by the Government Accountability Office with an abstract that begins "The American Recovery and Reinvestment Act of 2009 (Recovery Act) provided $70.3 billion for three education programs--the State Fiscal Stabilization Fund (SFSF); Title I, Part A of the Elementary and Secondary Education Act (Title I); and Individuals with Disabilities Education Act (IDEA), Part B. One goal of the Recovery Act was to save and create jobs, and SFSF also requires states to report information expected to increase transparency and advance educational reform. This report responds to two ongoing GAO mandates under the Recovery Act. It examines (1) how selected states and local recipients used the funds; (2) what plans the Department of Education (Education) and selected states have to assess the impact of the funds; (3) what approaches are being used to ensure accountability of the funds; and (4) how Education and states ensure the accuracy of recipient reported data. To conduct this review, GAO gathered information from 14 states and the District of Columbia, conducted a nationally representative survey of local educational agencies (LEA), interviewed Education officials, examined recipient reports, and reviewed relevant policy documents."

A letter report issued by the Government Accountability Office with an abstract that begins "Through the Child Care and Development Fund (CCDF), the U.S. Department of Health and Human Services (HHS) subsidizes child care for low-income families whose parents work or attend education or training programs. In fiscal year 2009, the CCDF budget was $7 billion. States are responsible for determining program priorities and overseeing funds. Providers--who range from child care centers to relatives--bill the state for caring for approved children. Unregulated relatives represent 12 percent of providers in the CCDF program. In response to program fraud and abuse, GAO (1) proactively tested selected states' fraud prevention controls, (2) examined closed case studies of fraud and abuse, and (3) interviewed parents waitlisted for child care about the effect of this lack of assistance on their families. To do this, GAO investigators posed as parents and unregulated relative providers in 10 scenarios in five states with no waiting lists that each received more than $100 million in CCDF funding for fiscal year 2009. These states did not require fingerprint criminal history checks or site visits. For case studies of past program fraud, GAO reviewed criminal court records and interviewed agency officials. …

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Quality Incentives Program (EQIP) assists agricultural producers who install conservation practices, such as planting vegetation along streams and installing waste storage facilities, to address impairments to water, air, and soil caused by agriculture or to conserve water. EQIP is a voluntary program managed by the U.S. Department of Agriculture's (USDA) Natural Resources Conservation Service (NRCS). NRCS allocates about $1 billion in financial and technical assistance funds to states annually. About $650 million of the funds are allocated through a general financial assistance formula. As requested, GAO reviewed whether USDA's process for allocating EQIP funds to states is consistent with the program's purposes and whether USDA has developed outcome-based measures to monitor program performance. To address these issues, GAO, in part, examined the factors and weights in the general financial assistance formula"

A letter report issued by the Government Accountability Office with an abstract that begins "In 2001, the Deputy Secretary of Defense stated that domestic violence will not be tolerated in the Department of Defense (DOD). Despite this posture, DOD's clinical database indicates that 8,223 incidents met criteria for domestic abuse in fiscal year 2009. However, because this database includes only cases reported to military clinical offices, it does not represent all cases. In response to a congressional request, GAO evaluated whether DOD is able to determine the effectiveness of its domestic abuse efforts. To conduct this review, GAO reviewed legislative requirements and DOD guidance, analyzed domestic abuse data, and interviewed officials involved in domestic abuse prevention and treatment and persons eligible to receive services at five military bases."

A letter report issued by the Government Accountability Office with an abstract that begins "Through its Financial and Logistics Integrated Technology Enterprise (FLITE) initiative, the Department of Veterans Affairs (VA) is developing a new system that is intended to fulfill the critical need for a modernized and integrated financial and asset management capability. FLITE is the successor to an earlier initiative that the department undertook--the Core Financial and Logistics System (CoreFLS)--which was discontinued in 2004. GAO was asked to determine (1) the department's overall plan for developing FLITE, (2) the status of its development efforts, (3) VA oversight of this initiative, and (4) whether lessons learned from the CoreFLS initiative have been considered and incorporated into the plan for developing FLITE. To achieve these objectives, GAO analyzed program documentation against relevant policies and best practices and interviewed program and project officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Until recently, ethics programs and practices of defense contractors were self-policed. Given the significant sums spent to acquire goods and services, the Federal Acquisition Regulation (FAR) was amended twice starting in December 2007 to first mandate and later amplify contractor ethics program rules. Before FAR changes were finalized in December 2008, Congress required GAO to report in 2009 on the ethics programs of major defense contractors. This report (1) describes the extent that contractors had ethics programs before the finalization of the FAR rules that included practices consistent with standards now required by the FAR and (2) assesses the impact the new FAR rules have on Department of Defense (DOD) oversight of contractor ethics programs. To do this work, in September 2008 GAO surveyed all 57 contractors--those receiving more than $500 million in 2006 DOD contract awards--and interviewed DOD contractor oversight agency officials on the impact of the new FAR rules on oversight."
