Delayed Failure Hydrogen Embrittlement of Zirconium. Quarterly Report No. 2, December 15, 1961 to March 14, 1962
The purpose of this investigation is to determine the extent to which Zr and Zr alloys exhibit delayed failure (static fatigune) as caused by a combination of absorbed H and applied stress. Both notched and unnotched specimens of unalloyed Zr and Zircaloy-2 were hydrogenated to 200 ppm and 500 ppm by means of a modified Sieverts apparatus; specimens were evaluated at room temperature. Thus far, no time-dependent fracture was observed which can be attributed to the delayed failure phenomenon; it appears that these materials are relatively insensitive to static fatigune. The effects of grain size, temperature, cold deformation, and superheated water and steam corrosion on susceptibility to delayed failure are being determined. (auth)

Determination of performance criteria for high-level solidified nuclear waste from the commercial nuclear fuel cycle: a probabilistic safety analysis
To minimize the radiological risk from the operation of a waste management system for the safe disposal of high-level waste, performance characteristics of the solidified waste form must be specified. The minimum waste form characteristics that must be specified are the radionuclide volatilization fraction, airborne particulate dispersion fraction, and the aqueous dissolution characteristics. The results indicate that the pre-emplacement environs are more limiting in establishing the waste form performance criteria than the post-emplacement environs. The actual values of expected risk are sensitive to modeling assumptions and data base uncertainties. The transportation step appears to be the most limiting in determining the required performance characteristics.

Stress Analysis of the SM-1A Reactor Vessel
The stress analysis performed on the SM-lA reactor vessel and cover is presented. The msximum combined stress (51,360 psi in compression) occurs in the vessel cover during a 50 deg F/hr transient. A fatigue analysis of these stresses indicated that they could be applied safely at least 2500 times, and since the vessel is expected to receive less than 900 cycles, it should not suffer any fatigue damage.

3D field harmonics
We have developed an harmonic representation for the three dimensional field components within the windings of accelerator magnets. The form by which the field is presented is suitable for interfacing with other codes that make use of the 3D field components (particle tracking and stability). The field components can be calculated with high precision and reduced cup time at any location (r,{theta},z) inside the magnet bore. The same conductor geometry which is used to simulate line currents is also used in CAD with modifications more readily available. It is our hope that the format used here for magnetic fields can be used not only as a means of delivering fields but also as a way by which beam dynamics can suggest correction to the conductor geometry. 5 refs., 70 figs.

Mirror Fusion Test Facility: an intermediate device to a mirror fusion reactor
The Mirror Fusion Test Facility (MFTF-B) now under construction at Lawrence Livermore National Laboratory represents more than an order-of-magnitude step from earlier magnetic-mirror experiments toward a future mirror fusion reactor. In fact, when the device begins operating in 1986, the Lawson criteria of ntau = 10/sup 14/ cm/sup -3/.s will almost be achieved for D-T equivalent operation, thus signifying scientific breakeven. Major steps have been taken to develop MFTF-B technologies for tandem mirrors. Steady-state, high-field, superconducting magnets at reactor-revelant scales are used in the machine. The 30-s beam pulses, ECRH, and ICRH will also introduce steady-state technologies in those systems.

Selective flotation of fossil resin from western coal
Economic analysis of this fossil resin project mainly focused on the flotation plant which is intended to be designed with data obtained from the current proof-of-concept flotation test program. It is believed that the analysis of this step is fairly accurate. The other two economic aspects of fossil in resin recovery/utilization are refining and marketing. Cost data used for refining were from an estimated base and are believed to have a large variance. Marketing data used were obtained from two independent marketing studies which were made available on confidentiality basis. Nevertheless, the data used are believed to be fairly accurate with respect to the market potential.

A 3 TeV on 3 TeV proton-proton dedicated collider for Fermilab
The Fermilab Dedicated Collider proposed in May 1983 is a 2 TeV on 2 TeV p)bar p) collider. The expected luminosity is )approximately) 10/sup 31/ cm/sup (minus/2)sec/sup )minus/1) and the estimated cost is )approximately) $362M (FY-83 dollars). Since 1983 both the superconducting magnet and the particle detector technologies have advanced and the countenance of physics, hence the desired characteristics of new facilities have also altered somewhat. We want to show here that with the new magnet technology used for the SSC one can construct a 3 TeV on 3 TeV pp collider on the Fermilab site. This pp Dedicated Collider )PPDC) will have a luminosity of about 10/sub 33/cm/sup )minus/2)sec)sup)minus)1) and a cost only )approximately) 50)percent) more than that of the p)bar p) Dedicated Collider. 3 figs

Ocean energy systems. Quarterly report, January-March 1983
Progress is reported on the development of Ocean Thermal Energy Conversion (OTEC) systems that will provide synthetic fuels (e.g., methanol), energy-intensive products such as ammonia (for fertilizers and chemicals), and aluminum. The work also includes assessment and design concepts for hybrid plants, such as geothermal-OTEC (GEOTEC) plants. Another effort that began in the spring of 1982 is a technical advisory role to DOE with respect to their management of the conceptual and preliminary design activity of industry teams that are designing a shelf-mounted offshore OTEC pilot plant that could deliver power to Oahu, Hawaii. In addition, a program is underway to evaluate and test the Pneumatic Wave-Energy Conversion System (PWECS), an ocean-energy device consisting of a turbine that is air-driven as a result of wave action in a chamber. This Quarterly Report summarizes the work on the various tasks as of 31 March 1983.

Private Pensions: Some Key Features Lead to an Uneven Distribution of Benefits
A letter report issued by the Government Accountability Office with an abstract that begins "Despite sizeable tax incentives, private pension participation has remained at about 50 percent of the workforce. For those in a pension plan, there is concern that these incentives accrue primarily to higher income employees and do relatively little to help lower income workers save for retirement. The financial crisis and labor-market downturn may have exacerbated these difficulties. Therefore, we examined (1) recent trends in new private pension plan formation, (2) the characteristics of defined contribution plan participants contributing at or above statutory limits, (3) how suggested options to modify an existing credit for low-income workers might affect their retirement income, and (4) the long-term effects of the recent financial crisis on retirement savings. To answer these questions, GAO reviewed reports, federal regulations, and laws, and interviewed academics, agency officials, and other relevant experts. We also analyzed Department of Labor and 2007 Survey of Consumer Finance (SCF) data, and used a microsimulation model to assess effects of modifying tax incentives for low-income workers. We incorporated technical comments from the departments of Labor and Treasury, the Internal Revenue Service, and the Pension Benefit Guaranty Corporation as appropriate."

Group Purchasing Organizations: Federal Oversight and Self-Regulation
Correspondence issued by the Government Accountability Office with an abstract that begins "GPOs are subject to certain federal laws that HHS, DOJ, and FTC are responsible for enforcing. According to HHS Office of Inspector General (HHS-OIG) officials, since 2004, the office has not routinely exercised its authority to request and review disclosures related to GPOs contract administrative fees, but it has collected information on GPOs contract administrative fees while conducting audits of hospitals cost reports. While HHS-OIG is responsible for enforcing the Anti-Kickback statute, the law and regulation do not require routine monitoring of GPO written agreements and disclosures. HHS-OIG officials told us that even if they requested this information from GPOs, it would not necessarily be sufficient to determine whether a GPO violated the Anti-Kickback statute. Officials from HHS-OIG also told us that, since 2004, it participated in two case investigations with DOJ that involved allegations that certain GPOs did not comply with safe harbor requirements and violated the Anti-Kickback statute. Officials told us that HHS-OIG has not imposed administrative penalties on any GPOs since 2004. DOJ and FTC have investigated complaints related to federal antitrust laws, and we identified one lawsuit filed by DOJ against a GPO in …

Securing Wastewater Facilities: Costs of Vulnerability Assessments, Risk Management Plans, and Alternative Disinfection Methods Vary Widely
A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, GAO reported that many large wastewater facilities have responded to this risk by voluntarily conducting vulnerability assessments and converting from chlorine gas to other disinfection methods. The Clean Air Act requires all wastewater facilities that use threshold quantities of chlorine gas to prepare and implement risk management plans to prevent accidental releases and reduce the severity of any releases. In this study, GAO was asked to provide information on (1) the range of costs large wastewater treatment facilities incurred in preparing vulnerability assessments and risk management plans, and (2) the costs large wastewater treatment facilities incurred in converting from chlorine gas to alternative disinfection processes. To answer these questions, GAO conducted structured telephone interviews with a number of facilities surveyed for the 2006 report. The Environmental Protection Agency (EPA) agreed with the report and provided several technical changes and clarifications."

8(a) Program: Fourteen Ineligible Firms Received $325 Million in Sole-Source and Set-Aside Contracts
A letter report issued by the Government Accountability Office with an abstract that begins "The Small Business Administration (SBA) helps socially and economically disadvantaged small businesses gain access to federal contracting opportunities through its 8(a) program. To participate, firms must be at least 51 percent owned and controlled by an individual who meets SBA's criteria of socially and economically disadvantaged. The firm must also qualify as a small business. Once certified, 8(a) firms are eligible to receive sole-source and set-aside contracts for up to 9 years. GAO was asked to (1) determine whether ineligible firms are participating in the 8(a) program, (2) proactively test SBA's controls over the 8(a) application process, and (3) determine what vulnerabilities, if any, exist in SBA's fraud prevention system. To identify cases, GAO reviewed SBA data and complaints to GAO's fraud hotline. To perform its proactive testing, GAO created four bogus businesses and applied for 8(a) certification. GAO did not attempt to project the extent of fraud and abuse in the program."

Global War on Terrorism: Reported Obligations for the Department of Defense
Correspondence issued by the Government Accountability Office with an abstract that begins "Since 2001, Congress has provided the Department of Defense (DOD) with about $808 billion in supplemental and annual appropriations, as of March 2009, primarily for military operations in support of the Global War on Terrorism (GWOT). DOD's reported annual obligations for GWOT have shown a steady increase from about $0.2 billion in fiscal year 2001 to about $162.4 billion in fiscal year 2008. For fiscal year 2009, Congress provided DOD with about $65.9 billion in supplemental appropriations for GWOT as of March 2009 and the President plans on requesting an additional $75.5 billion in supplemental appropriations for GWOT for the remainder of the fiscal year. A total of $31.0 billion has been obligated in the first quarter of fiscal year 2009 through December 2008. The United States' commitments to GWOT will likely involve the continued investment of significant resources, requiring decision makers to consider difficult trade-offs as the nation faces an increasing long-range fiscal challenge. The magnitude of future costs will depend on several direct and indirect cost variables and, in some cases, decisions that have not yet been made. DOD's future costs will likely be affected by …

Bureau of Justice Statistics: Quality Guidelines Generally Followed for Police-Public Contact Surveys, but Opportunities Exist to Help Assure Agency Independence
A letter report issued by the Government Accountability Office with an abstract that begins "The Bureau of Justice Statistics (BJS), a statistical agency of the Department of Justice's Office of Justice Programs, produces a recurring national Police-Public Contact Survey documenting contacts between the police and the public, including instances involving the use or threat of force by police. BJS issues public reports and sometimes press releases from survey results. For reports and a press release issued from the 1999 and 2002 surveys (the most recent available), GAO reviewed (1) the extent to which BJS followed quality guidelines to ensure the accuracy and integrity of its survey-related products, and (2) factors that affected whether and how BJS followed available guidelines. GAO reviewed applicable federal data quality guidelines, policy and procedure documents, and interviewed current and former officials familiar with BJS."

Cargo Container Inspections: Preliminary Observations on the Status of Efforts to Improve the Automated Targeting System
A statement of record issued by the Government Accountability Office with an abstract that begins "U.S. Customs and Border Protection's (CBP) Automated Targeting System (ATS)--a computerized model that CBP officers use as a decision support tool to help them target oceangoing cargo containers for inspection--is part of CBP's layered approach to securing oceangoing cargo. GAO reported in February 2004 on challenges CBP faced in targeting oceangoing cargo containers for inspection and testified before Congress in March 2004 about the findings in that report. The report and testimony outlined recommendations aimed at (1) better incorporating recognized modeling practices into CBP's targeting strategy, (2) periodically adjusting the targeting strategy to respond to findings that occur during the course of its operation, and (3) improving implementation of the targeting strategy. This statement for the record discusses preliminary observations from GAO's ongoing work related to ATS and GAO's 2004 recommendations addressing the following questions: (1) What controls does CBP have in place to provide reasonable assurance that ATS is effective at targeting oceangoing cargo containers with the highest risk of smuggled weapons of mass destruction? (2) How does CBP systematically analyze security inspection results and incorporate them into ATS? and (3) What steps has …

Surface Transportation: Competitive Grant Programs Could Benefit from Increased Performance Focus and Better Documentation of Key Decisions
A letter report issued by the Government Accountability Office with an abstract that begins "In February 2009, the American Recovery and Reinvestment Act (Recovery Act) appropriated $1.5 billion for discretionary grants for capital investments in surface transportation projects of national and regional significance, including highways, transit, rail, ports, and others. The act required the Department of Transportation (DOT) to develop criteria to award these grants--known as the Transportation Investment Generating Economic Recovery (TIGER) grants--and to meet several statutory requirements. GAO was asked to review (1) the criteria and process used to evaluate applications and award grants, (2) the outcome of the process, and (3) the extent to which DOT communicated information to applicants and the public. GAO reviewed documentation of the award process and selection documentation and interviewed key DOT officials."
