A detailed study of four reactor and shield configurations was made. Two basic reactor types, the boiling water and pressurized water reactors were considered. Shield materials of lead-water and iron-water were used with varying thicknesses for determining the optimum shield configuration for the PL-3 reactor. Also presented is a survey of available shielding codes. (auth)

This report discusses the following topics on the effect radiation has on thermonuclear reactor materials: Atomic Displacements; Microstructure Evolution; Materials Engineering, Mechanics, and Design; Research on Low-Activation Steels; and Research Motivated by Grant Support.

Mainstream projects which have adult fish passage facilities are inspected by project operators, fishway attendants, and state and federal fishery agencies. The overall movement of upstream migrants in 1984 appeared to be satisfactory with few delays. Special efforts were made by fishery agencies and Corps personnel to check on potential problems which appeared to exist at The Dalles and John Day Dams this year. However, adult passage facilities were operating ''in criteria'' and fish may have been delayed by temperature or other factors. Inspections were generally made once a month. Some projects were operating at less than full criteria as seen during inspections by fishery agencies this year. It appears that during periods of low tailwater, certain projects have difficulty maintaining proper head at main fishway entrances. Some main entrance gates bottom-out and water depth over these weirs are not up to desired criteria. Also it was noted that auxiliary water pumps were not being run at a rate to achieve the desired amount of water for attracting fish to the fish ladders and maintaining proper head at main fishway entrances.

A letter report issued by the Government Accountability Office with an abstract that begins "During its audit of the fiscal year 2012 consolidated financial statements of the U.S. government (CFS), GAO identified new and continuing control deficiencies in the Department of the Treasury's (Treasury) and the Office of Management and Budget's (OMB) processes used to prepare the CFS. These control deficiencies contributed to material weaknesses in internal control over the federal government's ability to"

A letter report issued by the Government Accountability Office with an abstract that begins "Political appointees in the federal government sometimes seek appointments to career competitive and other positions which, unlike political appointments, do not terminate at the end of an administration. Federal agencies must use appropriate authorities and follow proper procedures in making these conversions. GAO was asked to determine for departments and selected agencies (1) the number and characteristics of all political to career conversions occurring during the period from May 1, 2005, through May 30, 2009, and (2) whether appropriate authorities were used and proper procedures were followed in making these conversions at the GS-12 level and above."

A letter report issued by the Government Accountability Office with an abstract that begins "In an effort to help the millions of homeowners struggling to keep their homes, a range of federal programs have offered relief in the form of loan modifications and refinancing into loans with lower interest rates, among other things. Under Treasury’s Home Affordable Modification Program (HAMP), initiated in early 2009, servicers have modified almost 1 million loans between 2009 and 2011. During the same period, servicers modified nearly 1 million additional loans under programs administered by the Departments of Agriculture (USDA) and Veterans Affairs (VA), Federal Housing Administration (FHA), and Fannie Mae and Freddie Mac (the enterprises). Servicers have also modified about 2.1 million loans under nonfederal loan modification programs resulting in a total of about 4 million modifications between 2009 and 2011. However, a large number of borrowers have sought assistance, but were unable to receive a modification. For example, approximately 2.8 million borrowers had their HAMP loan modification application denied or their trial loan modification canceled. Further, the volume of federal modifications has declined since 2010. Recent efforts have expanded refinancing programs. However, low participation rates in FHA’s program raise questions about the need …

A letter report issued by the Government Accountability Office with an abstract that begins "Financial literacy plays an important role in helping ensure the financial health and stability of individuals and families, and efforts to improve consumers' financial literacy have grown in recent years. Currently, hundreds of nonprofit, private, and governmental entities provide some form of financial education to Americans. The federal government does not certify or approve organizations in general that provide financial literacy, although the U.S. Trustee Program and the Department of Housing and Urban Development (HUD) have approval processes for financial literacy providers for the purposes of meeting requirements of, respectively, the bankruptcy process and certain housing programs. In response to a mandate in the Dodd-Frank Wall Street Reform and Consumer Protection Act, this report addresses (1) what is known about which methods and strategies are effective for improving financial literacy, and (2) the feasibility of a process for certifying financial literacy providers. To address these objectives, GAO reviewed relevant literature, focusing on evidence-based evaluations of financial literacy programs or approaches; conducted interviews in the federal, nonprofit, private, and academic sectors; and examined the lessons learned from the approval processes of the Trustee Program and HUD."

A letter report issued by the Government Accountability Office with an abstract that begins "Since 2007, the Department of Agriculture's (USDA) Farm Service Agency (FSA), which administers various programs for farmers that help support farm incomes and provide disaster assistance, has established procedures for preventing improper payments to deceased individuals, including, on a quarterly basis, matching payments to program participants with the Social Security Administration's (SSA) data on deceased individuals. In addition, FSA state and county offices review and verify whether payments made to deceased individuals are proper or improper. Overall, these procedures have enabled FSA to identify thousands of deceased individuals who were paid $3.3 million in improper payments after their dates of death, of which FSA has recovered approximately $1 million. GAO reviewed a generalizable random sample of payments to deceased individuals that FSA identified as proper and found that 9 percent did not have sufficient support to be coded as proper. More monitoring to ensure that county offices' coding of payments is supported by documentation could help reduce the error rate."

A letter report issued by the Government Accountability Office with an abstract that begins "Congestion is increasing rapidly across the nation and freight traffic is expected to almost double in 20 years. In many places, decision makers cannot simply build their way out of congestion, and traditional revenue sources may not be sustainable. As the baby boom generation retires and the costs of federal entitlement programs rise, sustained, large-scale increases in federal highway grants seem unlikely. To provide the robust growth that many transportation advocates believe is required to meet the nation's mobility needs, state and local decision makers in virtually all states are seeking alternative funding approaches. Tolling (charging a fee for the use of a highway facility) provides a set of approaches that are increasingly receiving closer attention and consideration. This report examines tolling from a number of perspectives, namely: (1) the promise of tolling to enhance mobility and finance highway transportation, (2) the extent to which tolling is being used and the reasons states are using or not using this approach, (3) the challenges states face in implementing tolling, and (4) strategies that can be used to help states address tolling challenges. GAO is not making any …

A letter report issued by the Government Accountability Office with an abstract that begins "Special Operations Command's (SOCOM) duties have greatly increased since the attacks of September 11, 2001. Today, Special Operations Forces are at work in Afghanistan and Iraq, and SOCOM has been assigned to lead U.S. efforts in the Global War on Terrorism. SOCOM's acquisitions budget has also greatly increased in this period--more than doubling from $788 million in 2001 to approximately $1.91 billion in 2006. In light of SOCOM's expanded duties, Congress requested that GAO review SOCOM's management of its acquisition programs. GAO's evaluation includes an assessment of: the types of acquisition programs SOCOM has undertaken since 2001 and whether the programs are consistent with its mission; the extent to which SOCOM's programs have progressed as planned; and the challenges SOCOM faces in managing its acquisition programs."

A letter report issued by the Government Accountability Office with an abstract that begins "Federal agencies increasingly use recently developed Internet technologies that allow individuals or groups to create, organize, comment on, and share online content. The use of these social media services-- including popular Web sites like Facebook, Twitter, and YouTube-- has been endorsed by President Obama and provides opportunities for agencies to more readily share information with and solicit feedback from the public. However, these services may also pose risks to the adequate protection of both personal and government information. GAO was asked to (1) describe how federal agencies are currently using commercially provided social media services and (2) determine the extent to which agencies have developed and implemented policies and procedures for managing and protecting information associated with this use. To do this, GAO examined the headquarters-level Facebook pages, Twitter accounts, and YouTube channels of 24 major federal agencies; reviewed pertinent policies, procedures, and guidance; and interviewed officials involved in agency use of social media.."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has taken steps to establish an approach for managing DOD’s overall fuel demand, but is still developing comprehensive guidance to address fuel demand management, including at forward-deployed locations in countries such as Afghanistan. In 2009, GAO reported that DOD lacked (1) visibility and accountability for achieving fuel reduction, (2) incentives and a viable funding mechanism to invest in the implementation of fuel demand reduction projects, and (3) guidance and policies that addressed fuel demand at forward-deployed locations. In response to GAO recommendations, DOD has taken steps since 2009 to increase its visibility and accountability for fuel demand management at forward-deployed locations, including those located in Afghanistan. In addition, with an increased focus on fuel demand management, DOD has also provided funding and incentives to implement fuel demand management projects. Further, DOD has issued some guidance on fuel demand management at forward-deployed locations since 2009 and is developing more comprehensive guidance on how DOD will incorporate energy efficiency considerations into operations, planning, and training decisions for current military operations in Afghanistan and for future military operations. DOD’s 2012 Operational Energy Strategy Implementation …

A letter report issued by the Government Accountability Office with an abstract that begins "To protect workers' retirement security, the requesters asked GAO to assess: 1) What is known about conflicts of interest affecting private sector defined benefit (DB) plans? 2) What procedures does the Pension Benefit Guaranty Corporation (PBGC) have to identify and recover losses attributable to conflicts? 3) What procedures does Employee Benefits Security Administration (EBSA) have to detect conflicts among service providers and fiduciaries for PBGC-trusteed plans? 4) To what extent do EBSA, PBGC, and the Securities and Exchange Commission (SEC) coordinate their activities to investigate conflicts? GAO interviewed experts, including agency officials, attorneys, financial industry representatives, and academics, and GAO reviewed PBGC documentation and EBSA enforcement materials. GAO analyzed Labor, SEC, PBGC, and private sector data, including data on pensions, pension consultants, and rates of return data, and conducted statistical and econometric analyses."

A letter report issued by the Government Accountability Office with an abstract that begins "Identifying the federal grant workforce presents challenges due to differences in how agencies manage grants and the wide range of job series that make up the grant workforce. Some agencies manage grants by using a combination of program specialists (subject-matter experts) and grants management specialists, while other agencies use program specialists to manage the entire grant process. In the four agencies that GAO focused on for this review--the Departments of Education (Education), Health and Human Services (HHS), State (State), and Transportation (DOT)--agency officials identified over 5,100 employees who were significantly involved in managing grants, spanning more than 50 different occupational job series. Recognizing the need for a classification that would more accurately capture the work of federal employees who manage grants, in 2010 the Office of Personnel Management (OPM) created the "Grants Management Specialist" job series. However, due to the different ways that agencies manage grants, the extent to which agencies have adopted this series varies widely. More than half of the 22 federal grant-making agencies GAO surveyed make limited or no use of the job series. The Council on Financial Assistance Reform (COFAR), established by …

A letter report issued by the General Accounting Office with an abstract that begins "The Office of Management and Budget (OMB) requires agencies to certify the security controls of their information systems and to formally authorize and accept the risk associated with their operation (a process known as accreditation). These processes support requirements of the Federal Information Security Management Act of 2002 (FISMA). Further, OMB requires agencies to report the number of systems authorized following certification and accreditation as one of the key FISMA performance measures. In response to the Congressional request, GAO (1) identified existing governmentwide requirements and guidelines for certifying and accrediting information systems, (2) determined the extent to which agencies have reported their systems as certified and accredited, and (3) assessed whether their processes provide consistent, comparable results and adequate information for authorizing officials."

A letter report issued by the Government Accountability Office with an abstract that begins "The Transportation Equity Act for the 21st Century (TEA-21) and subsequent legislation authorized about $13.5 billion in guaranteed funding for the Federal Transit Administration's (FTA) New Starts program, which is used to select fixed guideway transit projects, such as rail and trolley projects, and to award full funding grant agreements (FFGA). GAO assessed the New Starts process for the fiscal year 2006 cycle. GAO identified (1) the number of projects that were evaluated, rated, and proposed for new FFGAs and the proposed funding commitments in the administration's budget request; (2) changes FTA has made to the New Starts application, evaluation, rating, and oversight processes since the fiscal year 2001 evaluation cycle and how these changes have been communicated to project sponsors; and (3) how FTA developed the measures used to evaluate and rate projects from the criteria outlined in TEA-21 and how those measures are used in the rating process."

A letter report issued by the Government Accountability Office with an abstract that begins "Medicaid--the federal-state health care financing program covering nearly 54 million low-income people at a cost of $276 billion in fiscal year 2003--is by its size and structure at risk of waste and exploitation. Because of challenges inherent in overseeing the program, administered federally by the Centers for Medicare & Medicaid Services (CMS), GAO in 2003 added Medicaid to its list of high-risk federal programs. To help administer the program, states may employ consultants in a number of roles, sometimes under contracts whereby payment is contingent upon the consultant's performance. GAO was asked to report on states' use of contingency-fee consultants. GAO examined the extent to which (1) states are using contingency-fee consultants for projects to maximize federal Medicaid reimbursements, (2) claims from contingency-fee projects in selected states are consistent with federal law and policy, and (3) states and CMS are overseeing claims from such projects."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Justice’s (Justice) website called FOIA.gov presents data from agencies’ annual Freedom of Information Act (FOIA) reports. Agencies submit their annual reports to Justice in print and in electronic form and Justice posts the electronic data onto the website. For fiscal year 2010, the data GAO reviewed on the website were generally consistent with the data in the agencies’ print versions. According to Justice officials, the department has taken steps to ensure accuracy and consistency of the data. These steps include providing annual training to agency personnel who are responsible for preparation of the FOIA annual reports and posting guidance for report completion and submission on the Office of Information Policy website. In addition, the department has implemented checks to ensure data consistency between the two report versions. Specifically, it has developed and provided agencies with a tool to be used in creating the electronic version for the website. The tool contains features that assist agencies in compiling their data and math checks to help ensure consistency. Further, Justice officials have a checklist they use as a guide for checking the consistency of the …

A letter report issued by the Government Accountability Office with an abstract that begins "Medicare spending on imaging services, among which are ultrasound procedures that use sound waves to facilitate diagnosis, nearly doubled from 1999 to 2004. The Congress required GAO to examine Medicare's payment methods for ultrasound procedures and whether the technicians that conduct them--called sonographers--should be subject to qualification standards, such as having to undergo a certification process called credentialing. This report addresses (1) the ultrasound procedures commonly used to diagnose medical conditions of Medicare beneficiaries, particularly for beneficiaries in a skilled nursing facility (SNF), (2) the financial impact of changing how Medicare pays for ultrasound exams and associated equipment and ambulance transportation for beneficiaries in a SNF, and (3) the factors for the Centers for Medicare & Medicaid Services (CMS) to consider in determining whether to establish credentialing or other requirements for sonographers. For this review, GAO analyzed Medicare claims data and conducted interviews and literature reviews."

A letter report issued by the Government Accountability Office with an abstract that begins "Billions of pounds of cargo are transported on U.S. passenger flights annually. The Department of Homeland Security's (DHS) Transportation Security Administration (TSA) is the primary federal agency responsible for securing the air cargo system. The 9/11 Commission Act of 2007 mandated DHS to establish a system to screen 100 percent of cargo flown on passenger aircraft by August 2010. As requested, GAO reviewed TSA's progress in meeting the act's screening mandate, and any related challenges it faces for both domestic (cargo transported within and from the United States) and inbound cargo (cargo bound for the United States). GAO reviewed TSA's policies and procedures, interviewed TSA officials and air cargo industry stakeholders, and conducted site visits at five U.S. airports, selected based on size, among other factors."

A letter report issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service (IRS) has made significant progress in improving its internal controls and financial management since its first financial statement audit in 1992, as evidenced by 12 consecutive years of clean audit opinions on its financial statements, the resolution of several material control deficiencies, and actions resulting in the closure of over 300 financial management recommendations. This progress has been the result of hard work throughout IRS and sustained commitment at the top levels of the agency. However, IRS still faces significant financial management challenges in (1) resolving its remaining material weaknesses and significant deficiency in internal control, (2) developing outcome-oriented performance metrics, and (3) correcting numerous other control deficiencies, especially those relating to safeguarding tax receipts and taxpayer information. At the beginning of GAO’s audit of IRS’s fiscal year 2011 financial statements, 77 recommendations from prior audits remained open because IRS had not fully addressed the underlying issues. During the fiscal year 2011 financial audit, IRS took actions that GAO considered sufficient to close 38 recommendations. At the same time, GAO identified additional control deficiencies resulting in 30 new recommendations. In total, 69 …

A letter report issued by the Government Accountability Office with an abstract that begins "The National Nuclear Security Administration’s (NNSA) management and operating (M&O) contractors differ in how they classify and allocate indirect costs at NNSA laboratories. Although different approaches are allowed by Cost Accounting Standards, these differences limit the ability to compare program costs across the laboratories. Recognizing the limitations of its current cost data, the Department of Energy (DOE) and NNSA are implementing the Institutional Cost Reporting initiative intended to create a standardized report of certain costs, including many indirect costs. However, DOE is uncertain how it will use the data gathered by this initiative, and these efforts may provide only limited improvements because the data will continue to only be reported at an aggregate level."

A letter report issued by the General Accounting Office with an abstract that begins "Recent U.S. combat operations in Kosovo, Afghanistan, and Iraq benefited from new Department of Defense (DOD) strategies and technologies, such as improvements in force networks and increased use of precision weapons, designed to address changes in the security environment resulting from the continuing terrorist threat and the advent of the information age. Based on the authority of the Comptroller General, GAO reviewed these conflicts, with a focus on bombing operations, to gain insight into the changes being implemented by DOD. This report focuses on (1) assessing the impact on operational effectiveness of improvements in force networks and in the use of precision weapons and (2) identifying key barriers to continued progress."

A letter report issued by the Government Accountability Office with an abstract that begins "The Deficit Reduction Act of 2005 (DRA) included a provision that requires states to obtain documentary evidence of U.S. citizenship or nationality when determining eligibility of Medicaid applicants and current beneficiaries; self-attestation of citizenship and nationality is no longer acceptable. The Centers for Medicare & Medicaid Services (CMS) issued regulations states must follow in obtaining this documentation. Interested parties have raised concerns that efforts to comply with the requirement will cause eligible citizens to lose access to Medicaid coverage and will be costly for states to implement. GAO was asked to examine how the requirement has affected individuals' access to Medicaid benefits and assess the administrative and fiscal effects of implementing the requirement. To do this work, GAO surveyed state Medicaid offices in the 50 states and the District of Columbia about their perspectives on access issues and the administrative and fiscal effects of the requirement. GAO obtained complete responses from 44 states representing 71 percent of national Medicaid enrollment in fiscal year 2004. GAO also reviewed federal laws, regulations, and CMS guidance."
