Since brazing was the method selected for joining the stainless steel SM- l reactor fuel element, corrosion studies were conducted on various potential brazing alloys to evaluate their resistance under the approximate pressurized- water conditions of the SM-1. The program consisted mainly of testing type 304L stainless steel T'' joints brazed with selected alloys in quiescent, degassed, and deionized autoclaved water at 565 deg F under 1200-psi pressure. In the initial phase of the investigation, tests were limited in duration to l000 hr in order to quickly screen some 18 potential alloys for longer time testing. Based on weight-change data and the metallographic examinations, five of the 18 alloys exhibited sufficient corrosion resistance to warrant further investigation. These alloys were subjected to autoclave tests of 12 and 16 months. In these extended tests, 1 cc O/sub 2/liter and a mixture of 1 cc O/sub 2/liter plus 50 cc H/sub 2/liter, respectively, were added to the water to more closely simulate SM- 1 reactor water conditions and to evaluate the effect of different gaseous additions on the corrosion behavior of the alloys. On the basis of weight-change data and metallographic examination after long-term exposure of the tested stainless steel-base joint; these …

A letter report issued by the Government Accountability Office with an abstract that begins "Radio frequency spectrum enables vital wireless communications services used by the federal government, businesses, and consumers. Spectrum capacity is necessary for wireless broadband (high-speed Internet access) and broadband deployment will boost the nation's capabilities in many important areas. As the demand for spectrum continues to increase, there is concern about adequate access to meet future needs. This requested report examines (1) how the National Telecommunications and Information Administration (NTIA) is managing spectrum needs of federal agencies, (2) how federal agencies are using and managing assigned spectrum, and (3) what steps NTIA has taken to meet recent initiatives aimed at making spectrum available for broadband. GAO reviewed NTIA's spectrum management documents; surveyed the 19 federal agencies comprising the Interdepartment Radio Advisory Committee; and interviewed NTIA officials and industry and academic experts."

A letter report issued by the Government Accountability Office with an abstract that begins "Over 3 years ago, Congress granted limited acquisition authority (LAA)--subject to delegation by the Secretary of Defense--to U.S. Joint Forces Command (JFCOM) for a 3-year period to expedite development and acquisition of certain warfighter equipment. Congress directed GAO to report on JFCOM LAA implementation. GAO's report, issued in November 2005, said JFCOM finished five LAA projects and was working on a sixth project, and that JFCOM had experienced difficulty finding funding to develop, acquire, and sustain LAA projects. Last year, Congress extended LAA through September 2008 and again directed GAO to report on LAA. This report updates the status of JFCOM LAA efforts since the authority was enacted and key LAA challenges."

A letter report issued by the Government Accountability Office with an abstract that begins "The Postal Accountability and Enhancement Act of 2006 required GAO to evaluate strategies and options for reforms of the United States Postal Service (USPS). USPS's business model is to fulfill its mission through self-supporting, businesslike operations; however, USPS has experienced increasing difficulties. Due to volume declines, losses, a cash shortage, and rising debt, GAO added USPS's financial condition to its high-risk list in July 2009. GAO's objectives were to assess (1) the viability of USPS's business model, (2) strategies and options to address challenges to its business model, and (3) actions Congress and USPS need to take to facilitate progress toward financial viability. GAO primarily drew on its past work; other studies; USPS data; interviews with USPS, unions, management associations, Postal Regulatory Commission, and mailing industry officials; and stakeholder input."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the Department of Veterans Affairs' (VA) changes in medical residency slots, focusing on: (1) VA's goals in realigning its residency program and the goals accomplished so far; (2) the reasons for changes in the number of graduate medical education residency slots; and (3) the views of VA facility and medical school officials on the effect of the changes on resident training and on the potential to train residents at VA community-based outpatient clinics."

A letter report issued by the General Accounting Office with an abstract that begins "This report reviews the Department of Defense's (DOD) management practices for demilitarizing excess ammunition. Specifically, GAO evaluates (1) the extent to which the excess ammunition stockpile has been reduced and whether the liability associated with excess ammunition has been fully identified, (2) the Army's reliance on contracted demilitarization and the impact of doing so on government facilities that use similar environmentally friendly processes, and (3) the feasibility of using excess ammunition for U.S. training needs. GAO found that DOD's reported stockpile of excess ammunition has grown rather than decreased, rising from 354,000 tons in 1993 to 493,000 tons at the end of 2000. In addition, the reported stockpile does not include all excess ammunition, which understates DOD's ultimate liability for demilitarizing ammunition. In recent years, the Army has devoted 50 percent of its excess ammunition demilitarization budget to contractors that use environmentally friendly demilitarization processes. Although a congressional directive resulted in greater emphasis on contractor demilitarization, the Army began and later expanded this effort without considering the effect it would have on government facilities. With increased contractor demilitarization, the Army has retained and underutilized environmentally friendly …

A letter report issued by the General Accounting Office with an abstract that begins "The General Services Administration (GSA), the federal government's real property manager, it is responsible for identifying, funding, and completing needed repairs and alterations at federal buildings. This report examines (1) GSA's process for assessing and selecting prospectus-level major repair and alteration design projects for funding, (2) the obstacles that impede GSA from satisfying its repair and alteration requirements, and (3) the consequences associated with deferring needed repairs and alterations at selected buildings. GAO found that in fiscal year 2001, GSA assessed the merits of 27 prospectus-level repair and alteration design projects and recommended 12 for funding. These projects were selected by a multifaceted process that relied on empirical data and professional judgment coupled with specific selection criteria and computer analysis that compared competing projects. GSA explained its decisions when it recommended lower-ranked projects for repairs. However, because of insufficient funding, those projects were placed on GSA's growing repair and alteration inventory. GSA has faced long-standing obstacles, including inadequate program data, the lack of a multiyear repair and alteration plan, and limited funding, in reducing this multibillion-dollar inventory. In addition, funding limitations remain a major obstacle. Delaying …

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the: (1) dental health status of Medicaid beneficiaries and other vulnerable populations; and (2) extent to which these groups have dental coverage and use dental services."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the financial statements of the Senate Restaurants Revolving Fund for the period ended September 30, 1999 and 1998. GAO contracted with the independent public accounting firm of KPMG Peat Marwick LLP to conduct the audit."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has identified 11 initiatives aimed at slowing its rising health care costs, but has not fully applied results-oriented management practices in developing plans to implement and monitor its initiatives. Results-oriented management practices include developing plans that identify goals, activities, and performance measures; resources and investments; organization roles, responsibilities, and coordination; and key external factors that could affect goals, such as a decrease of funding to a program. At the conclusion of GAO’s review, DOD had completed and approved a detailed implementation plan, including a cost savings estimate, for just 1 of its 11 initiatives. Developing cost savings estimates is critical to successful management of the initiatives for achieving the 2010 Quadrennial Defense Review’s call for reduced growth in medical costs. DOD also has not completed the implementation of an overall process for monitoring progress across its portfolio of health care initiatives and has not completed the process of identifying accountable officials and their roles and responsibilities for all of its initiatives. Without comprehensive, results-oriented plans, a monitoring process, and clear leadership accountability, DOD may be hindered in its ability to achieve …

A letter report issued by the Government Accountability Office with an abstract that begins "Of the approximately 400 non-federally recognized tribes that GAO identified, 26 received funding from 24 federal programs during fiscal years 2007 through 2010. Most of the 26 non-federally recognized tribes were eligible to receive this funding either because of their status as nonprofit organizations or state-recognized tribes. Similarly, most of the 24 federal programs that awarded funding to non-federally recognized tribes during the 4-year period were authorized to fund nonprofit organizations or state-recognized tribes. In addition, some of these programs were authorized to fund other entities, such as tribal communities or community development financial institutions."

A letter report issued by the Government Accountability Office with an abstract that begins "According to the National Research Council (NRC) and others, infrastructure such as roads and bridges, wastewater systems, and National Aeronautics and Space Administration (NASA) centers are vulnerable to changes in the climate. Changes in precipitation and sea levels, as well as increased intensity and frequency of extreme events, are projected by NRC and others to impact infrastructure in a variety of ways. When the climate changes, infrastructure-- typically designed to operate within past climate conditions--may not operate as well or for as long as planned, leading to economic, environmental, and social impacts. For example, the National Oceanic and Atmospheric Administration estimates that, within 15 years, segments of Louisiana State Highway 1-- providing the only road access to a port servicing 18 percent of the nation's oil supply--will be inundated by tides an average of 30 times annually due to relative sea level rise. Flooding of this road effectively closes the port."

A letter report issued by the Government Accountability Office with an abstract that begins "In October 2008, Congress passed the Prioritizing Resources and Organization for Intellectual Property Act of 2008 (PRO-IP Act), to improve the effectiveness of U.S. government efforts to protect intellectual property (IP) rights such as copyrights, patents, and trademarks. The act also directed GAO to provide information on the quantification of the impacts of counterfeit and pirated goods. GAO (1) examined existing research on the effects of counterfeiting and piracy on consumers, industries, government, and the U.S. economy; and (2) identified insights gained from efforts to quantify the effects of counterfeiting and piracy on the U.S. economy. GAO interviewed officials and subject matter experts from U.S. government agencies, industry associations, nongovernmental organizations, and academic institutions, and reviewed literature and studies quantifying or discussing the economic impacts of counterfeiting and piracy on the U.S. economy, industry, government, and consumers. GAO is making no recommendations in this report."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2006, the U.S. Postal Service (USPS) has closed redundant facilities and consolidated mail processing operations and transportation to reduce excess capacity in its network, resulting in reported cost savings of about $2.4 billion. Excess capacity remains, however, because of continuing and accelerating declines in First-Class Mail volume, automation improvements that sort mail faster and more efficiently, and increasing mail preparation and transportation by business mailers, much of whose mail now bypasses most of USPS’s processing network."

A letter report issued by the General Accounting Office with an abstract that begins "In 2002, the United States experienced one of the worst wildland fire seasons in the past 50 years--almost 7 million acres burned. These fires included the largest and costliest fire in Oregon in the past century--the Biscuit Fire. Following a lightning storm, five fires were discovered in the Siskiyou National Forest over a 3- day period beginning July 13. These fires eventually burned together to form the Biscuit Fire, which burned nearly 500,000 acres in southern Oregon and Northern California and cost over $150 million to extinguish. GAO evaluated (1) whether policies and procedures were in place for acquiring needed firefighting resources during the initial days of the Biscuit Fire, and the extent to which these policies and procedures were followed when the fire was first identified; (2) what resource management issues, if any, affected the ability of personnel to fight the fire; and (3) what differences, if any, existed in key certification standards for personnel among federal and state agencies and whether these differences affected efforts to respond to the fire. In commenting on a draft of this report, the Forest Service stated that the …

A letter report issued by the Government Accountability Office with an abstract that begins "In forming the Department of Homeland Security (DHS), there was concern that moving the U.S. Customs Service into the new DHS would diminish attention given to collection of customs revenue. In recognition of that concern, Congress required that DHS's Customs Border Protection (CBP) not reduce the staff or resources for customs revenue functions. In March 2003, CBP reported a baseline of 2,263 staff in nine customs revenue positions, and 1,006 staff in associated support positions. The SAFE Port Act required GAO to report on changes related to customs revenue functions since the formation of DHS. This report discusses staff resources, strategic workforce planning, and CBP's public reporting on customs revenue functions. GAO analyzed the number of customs revenue staff, legislatively required staffing levels, and strategic plans and annual performance reports."

A letter report issued by the Government Accountability Office with an abstract that begins "The Departments of Defense (DOD) and State and the U.S. Agency for International Development (USAID) have relied extensively on contractors in Iraq and Afghanistan, including using contractors to help administer other contracts or grants. Relying on contractors to perform such functions can provide benefits but also introduces potential risks, such as conflicts of interest, that should be considered and managed. Pursuant to the National Defense Authorization Act for Fiscal Year 2008, GAO reviewed (1) the extent to which DOD, State, and USAID rely on contractors to perform contract and grant administration in Iraq and Afghanistan; (2) the reasons behind decisions to use such contractors and whether the decisions are guided by strategic workforce planning; and (3) whether agencies considered and mitigated related risks. GAO analyzed relevant federal and agency policies and agency contract data, and conducted file reviews and interviews for 32 contracts selected for case studies."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Agriculture's (USDA) Agricultural Research Service (ARS) and the National Institute of Food and Agriculture (NIFA) generally focus on many of the same broad topics and rely on agency safeguards, as well as on the scientific community's professional norms, to prevent inadvertent duplication of research projects within and between the agencies. Shortcomings with certain agency safeguards, however, may increase the potential risk of project duplication within or between the two agencies. ARS and NIFA built in their own safeguards to help prevent project duplication, such as (1) panels of independent external scientists who review proposed projects and (2) agency requirements for staff to ensure that proposed work is relevant, including checking the Current Research Information System (CRIS)--USDA's primary system containing project-level information on its ongoing and completed research projects--for potentially duplicative research projects in both agencies. The agencies also rely on professional norms to safeguard against duplication, such as the peer review process used by scientific journals to limit the publication of unnecessarily duplicative research. Indeed, agency officials and stakeholders could not provide recent examples of duplication within or between the two agencies, and …

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the Brady Act's phase I (interim Brady) and phase II (permanent Brady) provisions in preventing the sale of firearms to prohibited individuals, focusing on: (1) how the permanent Brady compares with the interim Brady; (2) under permanent Brady, the advantages and disadvantages of the National Instant Criminal Background Check System's (NICS) background checks conducted by a designated state agency versus by the Federal Bureau of Investigation (FBI); (3) under permanent Brady, the extent to which default proceeds resulted in firearms being sold to prohibited individuals; and (4) the options policymakers have in preventing or minimizing such transfers."

A letter report issued by the General Accounting Office with an abstract that begins "In recent years, concerns have been raised that new courtrooms continue to be built for district judges, even though existing courtrooms appear to be under used. The judiciary wants to maintain its one-judge, one-courtroom policy because of concerns about the effect of shared courtroom space on judicial administration. The judiciary has not, however, determined whether courtroom sharing may be possible among senior judges--the likeliest candidates for such an arrangement because of their reduced caseloads. Some active and senior judges in areas with a courtroom shortage are currently sharing space. Many of these judges oppose courtroom sharing because they believe that it interferes with the courts business and harms the judicial process. The judiciary plans to have some senior judges share space in future courthouse projects. Significant courtroom sharing appears unlikely in the near future, even among senior judges."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO reviewed the Navy's compliance with the reporting requirements stated in section 1011 of the National Defense Authorization Act for Fiscal Year 1996, focusing on whether the Navy: (1) lists and maintains at least two Iowa class battleships on the Naval Vessel Register that are in good material condition and capable of providing adequate fire support for an amphibious assault; (2) retains the existing logistical support necessary to keep at least two Iowa class battleships in active service, including technical manuals, repair and replacement parts, and ordnance; and (3) keeps the two battleships on the register until the Secretary of the Navy certifies that the Navy has within the fleet an operational surface fire support capability that equals or exceeds the fire support capability that the Iowa class battleships would be able to provide for the Marine Corps amphibious assaults and operations ashore."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the Department of Energy's (DOE) management and disposal of its low-level radioactive wastes, focusing on: (1) the factors that influence DOE's decisions about the treatment, storage, and disposal of the wastes; and (2) DOE's costs to treat, store, and dispose of these wastes and the cost-effectiveness of DOE's disposal decisions."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the Department of Defense's (DOD) implementation of its Total Asset Visibility (TAV) initiative, focusing on: (1) the difficulty in determining the status of the initiative's implementation; (2) planning weaknesses that affect the initiative's implementation; and (3) strategies for addressing those weaknesses."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed selected fiscal year (FY) 1999 federal agency performance plans, focusing on: (1) agencies' approaches to linking performance goals and budgetary resources; (2) characteristics that might be associated with different approaches to linking performance goals and budgetary resources; and (3) implications for future efforts to clarify the relationship between budgetary resources and results."
