Advanced Gas Cooled Nuclear Reactor Materials Evaluation and Development Program. Progress report, January 1, 1980-March 31, 1980
Results are presented of work performed on the Advanced Gas-Cooled Nuclear Reactor Materials Evaluation and Development Program. The objectives of this program are to evaluate candidate alloys for Very High Temperature Reactor (VHTR) Nuclear Process Heat (NPH) and Direct Cycle Helium Turbine (DCHT) applications, in terms of the effect of simulated reactor primary coolant (helium containing small amounts of various other gases), high temperatures, and long time exposures, on the mechanical properties and structural and surface stability of selected candidate alloys. A second objective is to select and recommend materials for future test facilities and more extensive qualification programs. Included are the activities associated with the status of the simulated reactor helium supply system, testing equipment and gas chemistry analysis instrumentation and equipment. The progress in the screening test program is described, including screening creep results and metallographic analysis for materials thermally exposed or tested at 750, 850, and 950/sup 0/C.

Method and apparatus for aerosol-particle absorption spectroscopy. [DOE patent application]
A method and apparatus are described for determining the absorption spectra, and other properties, of aerosol particles. A heating beam source provides a beam of electromagnetic energy which is scanned through the region of the spectrum which is of interest. Particles exposed to the heating beam which have absorption bands within the band width of the heating beam absorb energy from the beam. The particles are also illuminated by light of a wave length such that the light is scattered by the particles. The absorption spectra of the particles can thus be determined from an analysis of the scattered light since the absorption of energy by the particles will affect the way the light is scattered. Preferably the heating beam is modulated to simplify the analysis of the scattered light. In one embodiment the heating beam is intensity modulated so that the scattered light will also be intensity modulated when the particles absorb energy. In another embodiment the heating beam passes through an interferometer and the scattered light reflects the Fourier Transform of the absorption spectra.

GAMIDEN: a program to aid in the identification of unknown materials by gamma-ray spectroscopy
The intent of the computer code GAMIDEN is to help identify isotopes by their gamma-ray emissions and thus to assist in the nondestructive assay of unknown materials. From both radioactive decays and neutron captures, GAMIDEN searches GAMTOT78, a file of gamma-ray spectra, for matches with observed photon energies. This report describes the search procedure, outlines the use of the code, and gives an example. The code is designed to operate on the CRAY 1 computer at Lawrence Livermore National Laboratory (LLNL). It is written in standard Fortran (ANSI) for the most part but contains some LRLTRAN instructions to make use of the Livermore time-sharing system (LTSS). The code uses about 545,000 words of memory. Typical problems run in about 45 s. The source program and the data file are available on request.

Evaluation of cracking in feedwater piping adjacent to the steam generators in Nine Pressurized Water Reactor Plants
Cracking in ASTM A106-B and A106-C feedwater piping was detected near the inlet to the steam generators in a number of pressurized water reactor plants. We received sections with cracks from nine of the plants with the objective of identifying the cracking mechanism and assessing various factors that might contribute to this cracking. Variations were observed in piping surface irregularities, corrosion-product, pit, and crack morphology, surface elmental and crystal structure analyses, and steel microstructures and mechanical properties. However, with but two exceptions, namely, arrest bands and major surface irregularities, we were unable to relate the extent of cracking to any of these factors. Tensile and fracture toughness (J/sub Ic/ and tearing modulus) properties were measured over a range of temperatures and strain rates. No unusual properties or microstructures were observed that could be related to the cracking problem. All crack surfaces contained thick oxide deposits and showed evidence of cyclic events in the form of arrest bands. Transmission electron microscopy revealed fatigue striations on replicas of cleaned crack surfaces from one plant and possibly from three others. Calculations based on the observed striation spacings gave a value of ..delta..sigma = 150 MPa (22 ksi) for one of the major cracks. …

Antidumping and Countervailing Duties: Key Challenges to Small and Medium-Sized Enterprises' Pursuit of the Imposition of Trade Remedies
A letter report issued by the Government Accountability Office with an abstract that begins "Some small and medium-sized enterprises (SME)--which are defined by the Small Business Administration's Office of Advocacy as independent businesses with fewer than 500 employees--have petitioned for the imposition of antidumping (AD) and countervailing (CV) duties to seek relief from unfair trade practices. Among the 56 petitions filed between 2007 and 2012, GAO found 21 that included at least 1 SME petitioner. In addition, the 56 petitions represented a total of 147 petitioners, of which 38 were SMEs. The majority of these SME petitioners had annual sales revenue of at least $10 million. Close to half of the total SME petitioners were in the iron and steel industry. Since participation in the petitions is not mandatory, producers, including SMEs, may benefit from a successful petition even if they choose not to join as a petitioner."

Information Sharing Environment: Definition of the Results to Be Achieved in Improving Terrorism-Related Information Sharing Is Needed to Guide Implementation and Assess Progress
A letter report issued by the Government Accountability Office with an abstract that begins "The attacks on 9/11 underscored the federal government's need to facilitate terrorism-related information sharing among government, private sector, and foreign stakeholders. In response, the Intelligence Reform and Terrorism Prevention Act of 2004 mandated the creation of the Information Sharing Environment (ISE), which is described as an approach for the sharing of terrorism-related information. A presidentially appointed Program Manager oversees ISE development with assistance from the Information Sharing Council (ISC), a forum for 16 information sharing officials from federal agencies and departments. GAO was asked to report on (1) what actions have been taken to guide the design and implementation of the ISE and (2) what efforts have been made to report on progress in implementing the ISE. To perform this work, GAO reviewed related laws, directives, guidance, and ISE planning and reporting documents and interviewed officials from the Program Manager's office and key agencies who serve on the ISC."

The High-Speed Rail Investment Act of 2001 (S. 250)
A briefing report issued by the General Accounting Office with an abstract that begins "The High-Speed Rail Investment Act of 2001 would allow the National Railroad Passenger Corporation (Amtrak) to issue up to $12 billion in "tax credit bonds" over 10 years, primarily for capital improvement projects designated high-speed rail corridors and on Amtrak's Northeast Corridor. This report reviews the (1) cost of the bond-financing mechanism and alternatives to the U.S. Treasury, (2) degree to which bond proceeds would meet the capital needs of federally designated high-speed rail corridors, and (3) extent of the federal oversight role. GAO found that the estimated tax credit for Amtrak bonds would cost the U.S. Treasury between $16.6 billion and $19.1 billion (in nominal dollars) over 30 years. The overall capital needs of fully developed federally designed high-speed rail corridors are unknown because these initiatives are in various stages of planning, but preliminary estimates by Amtrak puts the capital costs for fully developed high-speed rail corridors and its Northeast Corridor at between $50 billion and $70 billion over 20 years.The proposed legislation would require the Secretary of the Treasury to report annually on whether the amount of money in the trust account is sufficient …

Human Capital: Continued Monitoring of Internal Safeguards and an Action Plan to Address Employee Concerns Could Improve Implementation of the National Security Personnel System
A statement of record issued by the Government Accountability Office with an abstract that begins "DOD is in the process of implementing this human capital system, and according to DOD, about 212,000 civilian employees are currently under the system. On February 11, 2009, however, the House Armed Services Committee and its Subcommittee on Readiness asked DOD to halt conversions of any additional employees to NSPS until the administration and Congress could properly address the future of DOD's personnel management system. On March 16, 2009, DOD and the Office of Personnel Management (OPM) announced an upcoming review of NSPS policies, regulations, and practices. According to DOD, the department has delayed any further transitions of employees into NSPS until at least October 2009--pending the outcome of its review. Furthermore, on May 14, 2009, the Deputy Secretary of Defense asked the Defense Business Board to form what has become this task group to review NSPS to help the department determine, among others things, whether NSPS is operating in a fair, transparent, and effective manner. This statement focuses on the performance management aspect of NSPS specifically (1) the extent to which DOD has implemented internal safeguards to ensure the fairness, effectiveness, and credibility of …

Foreign Military Sales: Improved Navy Controls Could Prevent Unauthorized Shipments of Classified and Controlled Spare Parts to Foreign Countries
A letter report issued by the General Accounting Office with an abstract that begins "From 1993 through 2002, the Department of Defense (DOD) delivered over $150 billion in services and defense articles, including classified and controlled items, to foreign countries through foreign military sales programs administered by the military. Foreign countries may request items using blanket orders, which are for a specific dollar value and are used to simplify supply actions on certain types of items. GAO was asked to review whether the Navy's key internal controls restricted blanket orders for (1) classified spare parts and (2) controlled items sold to foreign countries. Also, GAO was asked to determine if periodic tests were conducted to ensure that the Navy's system is working as intended."

Medicare Dialysis Facilities: Beneficiary Access Stable and Problems in Payment System Being Addressed
A letter report issued by the General Accounting Office with an abstract that begins "Medicare covers about 90 percent of patients with end-stage renal disease (ESRD), the permanent loss of kidney function. Most ESRD patients receive regular hemodialysis treatments, a process that removes toxins from the blood, at a dialysis facility. A small percentage dialyzes-at home. From 1991 through 2001, the ESRD patient population more than doubled, from about 201,000 to 406,000. As the need for services grows, so do concerns about beneficiary access to and Medicare payment for dialysis services. The Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 directed GAO to study beneficiaries' access to dialysis services. In this report, GAO (1) assessed the supply of dialysis facilities and the services they provide, overall and relative to beneficiary residence, and (2) assessed the extent to which Medicare payments for dialysis services are adequate and the methodology is appropriate. In order to assess the supply of dialysis facilities, GAO used Facility Surveys collected by the Centers for Medicare & Medicaid Services (CMS) and outpatient claims, the bills submitted to Medicare by providers of certain outpatient services from 1998 through 2001. To assess the adequacy of Medicare …

Video Marketplace: Competition Is Evolving, and Government Reporting Should Be Reevaluated
A letter report issued by the Government Accountability Office with an abstract that begins "Since GAO reported on competition in 2005, competition among video content producers is little changed, while competition among distributors has increased. According to data cited by the Federal Communications Commission (FCC), seven companies' broadcast and cable networks accounted for about 95 percent of all television viewing hours in the United States. Further, ownership of broadcast and cable networks changed little from 2005 through 2012. Alternatively, the introduction of video service provided by telephone companies, such as Verizon's FiOS service, has brought additional competition to video distribution. At year-end 2010, roughly 1 in 3 households could choose among 4 or more subscription video distributors: typically a cable company, 2 satellite companies, and a telephone company. With technological advances, companies are increasingly distributing video online. Online video distributors (OVD) are developing a variety of business models, including free and subscription-based services. However, online viewing and revenues represent a small portion of overall media viewing hours and revenue."
