Milliwatt generator heat source. Progress report, July-December 1981
As part of the Milliwatt Generator (MWG) Program, a second series of pressure burst capsules welded offsite was tested; the resulting data indicate that the welds are very similar to those in the first series of capsules. Sufficient hardware was fabricated to meet all scheduled commitments. To provide a unit for feasibility testing, a heat source clad with Hastelloy C was reclad with Inconel 600. Forming development tests on Inconel 600 were conducted with favorable results. A QAS-3 survey was conducted and a satisfactory rating was received. Lot 11 qualification began on T-111 materials. The production period ended with an overall process yield of 99.6%, and a dollar percent defective rate of 0.60%.

Imaging system for obtaining space- and time-resolved plasma images on TMX
A Reticon 50 x 50 photodiode array camera has been placed on Livermore's Tandem Mirror Experiment to view a 56-cm diameter plasma source of visible, vacuum-ultraviolet, and x-ray photons. The compact camera views the source through a pinhole, filters, a fiber optic coupler, a microchannel plate intensifier (MCPI), and a reducer. The images are digitized (at 3.3 MHz) and stored in a large, high-speed memory that has a capacity of 45 images. A local LSI-11 microprocessor provides immediate processing and display of the data. The data are also stored on floppy disks that can be further processed on the large Livermore Computer System. The temporal resolution is limited by the fastest MCPI gate. The number of images recorded is determined by the read-out time of the Reticon camera (minimum 0.9 msec). The spatial resolution of approximately 1.4 cm is fixed by the geometry and the pinhole of 0.025 cm. Typical high-quality color representation of some plasma images are included.

Present capabilities and new developments in antenna modeling with the numerical electromagnetics code NEC
Computer modeling of antennas, since its start in the late 1960's, has become a powerful and widely used tool for antenna design. Computer codes have been developed based on the Method-of-Moments, Geometrical Theory of Diffraction, or integration of Maxwell's equations. Of such tools, the Numerical Electromagnetics Code-Method of Moments (NEC) has become one of the most widely used codes for modeling resonant sized antennas. There are several reasons for this including the systematic updating and extension of its capabilities, extensive user-oriented documentation and accessibility of its developers for user assistance. The result is that there are estimated to be several hundred users of various versions of NEC world wide. 23 refs., 10 figs.

Laboratory procedures used in the hot corrosion project
The objective of the Hot Corrosion Project in the LLNL Metals and Ceramics Division is to study the physical and chemical mechanisms of corrosion of nickel, iron, and some of their alloys when these metals are subjected to oxidizing or sulfidizing environments at temperatures between 850 and 950/sup 0/C. To obtain meaningful data in this study, we must rigidly control many parameters. Parameters are discussed and the methods chosen to control them in this laboratory. Some of the mechanics and manipulative procedures that are specifically related to data access and repeatability are covered. The method of recording and processing the data from each experiment using an LS-11 minicomputer are described. The analytical procedures used to evaluate the specimens after the corrosion tests are enumerated and discussed.

Tobacco Products: FDA Spending and New Product Review Time Frames
Testimony issued by the Government Accountability Office with an abstract that begins "The Food and Drug Administration (FDA) spent (obligated) less than half of the $1.1 billion in tobacco user fees it collected from manufacturers and others from fiscal year 2009 through the end of fiscal year 2012; however, FDA's spending increased substantially in fiscal year 2013. Through December 31, 2013, FDA spent nearly 81 percent of the approximately $1.75 billion in fees collected by that time. According to officials in FDA's Center for Tobacco Products (CTP), the center established by the Family Smoking Prevention and Tobacco Control Act (Tobacco Control Act) to implement the act's provisions, the time it took to award contracts contributed to the center spending less than it had planned to spend. In fiscal year 2013, FDA was able to carry out a number of activities that were originally planned for fiscal years 2011 and 2012, such as efforts to educate youth on the dangers of tobacco use. About 79 percent ($1.12 billion) of user fees spent as of December 31, 2013, was spent by three CTP offices: Office of Health Communication and Education, Office of Science, and Office of Compliance and Enforcement."

Government Efficiency and Effectiveness: Opportunities to Reduce Fragmentation, Overlap, and Duplication and Achieve Other Financial Benefits
Testimony issued by the Government Accountability Office with an abstract that begins "GAO's 2014 annual report identifies 64 new actions that executive branch agencies and Congress could take to improve the efficiency and effectiveness of 26 areas of government. GAO identifies 11 new areas in which there is evidence of fragmentation, overlap, or duplication. For example, under current law, individuals are allowed to receive concurrent payments from the Disability Insurance and Unemployment programs. Eliminating the overlap in these payments could save the government about $1.2 billion over the next 10 years. GAO also identifies 15 new areas where opportunities exist either to reduce the cost of government operations or enhance revenue collections. For example, Congress could rescind all or part of the remaining $4.2 billion in credit subsidies for the Advanced Technology Vehicles Manufacturing Loan program unless the Department of Energy demonstrates sufficient demand for this funding."

Paid Tax Return Preparers: In a Limited Study, Preparers Made Significant Errors
Testimony issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service's (IRS) authority to regulate the practice of representatives before IRS is limited to certain preparers, such as attorneys and certified public accountants. Unenrolled preparers—those generally not subject to IRS regulation—accounted for 55 percent of all preparers as of March 2014. In 2010, IRS initiated steps to regulate unenrolled preparers through testing and education requirements; however, the courts ruled that IRS lacked the authority."

Mine Safety: Additional Guidance and Oversight of Mines' Emergency Response Plans Would Improve the Safety of Underground Coal Miners
A letter report issued by the Government Accountability Office with an abstract that begins "In 2006, several mining tragedies led the Congress to pass the Mine Improvement and New Emergency Response Act of 2006 (MINER Act). The law required underground coal mine operators to develop emergency response plans that contain several components designed to improve accident preparedness and response, including providing a refuge of air to miners trapped underground after an accident and wireless communications systems. The Mine Safety and Health Administration (MSHA) is responsible for approving the plans and ensuring their implementation. GAO examined (1) the effectiveness of the approval process, (2) the status of implementation of the plans, and (3) MSHA's efforts to enforce and oversee implementation. To address these questions, GAO reviewed a nonprobability sample of emergency response plans, analyzed MSHA data, and interviewed MSHA officials and members of the mining community."

Bureau of Prisons: Evaluating the Impact of Protective Equipment Could Help Enhance Officer Safety
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Justice's (DOJ) Federal Bureau of Prisons (BOP) manages more than 209,000 inmates, up 45 percent between fiscal years 2000 and 2010. As the prison population grows, so do concerns about correctional officer safety. As requested, GAO examined the (1) equipment that BOP and selected state departments of corrections (DOC) provide to protect officers, and the officers' and other correctional practitioners' opinions of this equipment; (2) extent to which BOP has evaluated the effectiveness of this equipment, and factors correctional equipment experts consider important to the acquisition of new equipment; and (3) institutional factors correctional accrediting experts reported as impacting officer safety, and the extent to which BOP has evaluated the effectiveness of the steps it has taken in response. GAO reviewed BOP policies and procedures; interviewed BOP officials and officers within BOP's six regions, selected based on such factors as the level of facility overcrowding; interviewed officials at 14 of the 15 largest state DOCs; and surveyed 21 individuals selected for their expertise in corrections. The results of the interviews cannot be generalized, but provide insight into issues affecting officer safety."

Commercial Nuclear Waste: Effects of a Termination of the Yucca Mountain Repository Program and Lessons Learned
A letter report issued by the Government Accountability Office with an abstract that begins "Spent nuclear fuel--considered very hazardous--is accumulating at commercial reactor sites in 33 states. The Nuclear Waste Policy Act of 1982, as amended, directs the Department of Energy (DOE) to dispose of this waste in a repository at Yucca Mountain, Nevada. In June 2008, DOE submitted a license application for the repository, but in March 2010 moved to withdraw it. However, the Nuclear Regulatory Commission (NRC) or the courts--as a result of lawsuits--could compel DOE to resume the licensing process. This report examines (1) the basis for DOE's decision to terminate the Yucca Mountain program, (2) the termination steps DOE has taken and their effects, (3) the major impacts if the repository were terminated, and (4) the principal lessons learned. GAO reviewed documents and interviewed knowledgeable parties."

Military Capabilities: Navy Should Reevaluate Its Plan to Decommission the USS <em>Port Royal</em>
A letter report issued by the Government Accountability Office with an abstract that begins "The Navy's 2013 report to Congress on the Port Royal 's material condition partially addressed congressional reporting requirements but has likely overstated modernization costs should the ship be retained in service. While the Navy acknowledges that it did not obtain an independent structural assessment as required by one of the mandates, the Navy found the condition of the ship to be comparable to other cruisers when its own technical experts assessed the ship. For example, in addressing the congressional requirements, the Navy assessed the Port Royal 's structure and found the condition of the superstructure and interior hull to be typical of other cruisers in the class, indicating its suitability for continued use. The mandate also required that the Navy's assessments be reviewed by experts. GAO found that the Navy's assessment was reviewed by the Naval Sea Systems Command Engineering Directorate, the Navy's technical authority, and by independent boards of subject-matter experts from the Department of Defense and industry—the Board of Inspection and Survey and the American Bureau of Shipping, respectively. All three reviewers generally concurred with the assessment. Finally, the Navy's report to Congress included …

Nuclear Regulatory Commission: NRC Needs to Do More to Ensure that Power Plants Are Effectively Controlling Spent Nuclear Fuel
A letter report issued by the Government Accountability Office with an abstract that begins "Spent nuclear fuel--the used fuel periodically removed from reactors in nuclear power plants--is too inefficient to power a nuclear reaction, but is intensely radioactive and continues to generate heat for thousands of years. Potential health and safety implications make the control of spent nuclear fuel of great importance. The discovery, in 2004, that spent fuel rods were missing at the Vermont Yankee plant in Vermont generated public concern and questions about the Nuclear Regulatory Commission's (NRC) regulation and oversight of this material. GAO reviewed (1) plants' performance in controlling and accounting for their spent nuclear fuel, (2) the effectiveness of NRC's regulations and oversight of the plants' performance, and (3) NRC's actions to respond to plants' problems controlling their spent fuel."

American Samoa and Commonwealth of the Northern Mariana Islands: Wages, Employment, Employer Actions, Earnings, and Worker Views Since Minimum Wage Increases Began
A letter report issued by the Government Accountability Office with an abstract that begins "In 2007, the United States enacted a law incrementally raising the minimum wages in American Samoa and the Commonwealth of the Northern Mariana Islands (CNMI). The law applied the first $.50 per hour increase in July 2007 and mandated additional increases in each subsequent year until the minimum wages reach the level of the U.S. minimum wage--currently $7.25 per hour. American Samoa's lowest paid will reach that wage in 2016, and the CNMI in 2015. In American Samoa, one of two tuna canneries employing almost a third of workers closed in September 2009. In the CNMI, where the garment industry was one of two major employers, the last garment factory closed in early 2009. The American Recovery and Reinvestment Act requires GAO to report annually on the impact of the minimum wage increases in American Samoa and the CNMI. In this report GAO describes, since the increases began, wages, employment, employer actions, inflation-adjusted earnings, and worker views. GAO reviewed existing information from federal and local sources. GAO also collected data from large employers (at least 50 employees) through a questionnaire and from small employers and workers …

NASA: Compliance with Cost Limits
Correspondence issued by the Government Accountability Office with an abstract that begins "Section 202 of the National Aeronautics and Space Administration (NASA) Authorization Act of 2000, Pub. L. No. 106-391, 202, 114 Stat. 1577, 1587 (Oct. 30, 2000) requires that GAO verify NASA's accounting for amounts obligated against established limits for the space station and related space shuttle support. Under the act, obligations are limited to $25 billion for the International Space Station's (ISS) development and $17.7 billion for shuttle launches in connection with the space station's assembly. In the past, we have advised Congressional committees that NASA was unable to provide detailed support for the amounts obligated against the limits. Thus, we could not verify the amounts that NASA reported in its budget requests to Congress."

Nuclear Weapons: Actions Needed to Address Scientific and Technical Challenges and Management Weaknesses at the National Ignition Facility
A letter report issued by the Government Accountability Office with an abstract that begins "In March 2009, the National Nuclear Security Administration (NNSA), a separately organized agency within the Department of Energy, completed construction of the National Ignition Facility (NIF). NNSA considers NIF critical to its stockpile stewardship program to ensure the safety and reliability of the nation's nuclear weapons, absent live nuclear testing. NIF is intended to simulate the extreme temperatures and pressures of "ignition"--an atomic fusion event propagating a nuclear explosion--for the first time in a laboratory. GAO was asked to examine (1) the extent to which NNSA has addressed key scientific and technical challenges that could prevent ignition at NIF; (2) whether NNSA has an effective approach for managing the cost, schedule, and scope of ignition-related activities; and (3) potential impacts to NNSA's stockpile stewardship program if ignition at NIF is not achieved, as planned, between fiscal years 2010 and 2012. To conduct this work, GAO analyzed relevant budgets, reports, and plans, and interviewed NNSA and national laboratory officials and independent experts."

Means-Tested Programs: Information on Program Access Can Be an Important Management Tool
A letter report issued by the Government Accountability Office with an abstract that begins "Federal agencies that administer means-tested programs are responsible for both ensuring that people have appropriate access to assistance and ensuring the integrity of the programs they oversee. To balance these two priorities appropriately, it is important for agencies to have information on program integrity and program access. Knowing the proportion of the population that qualifies for these programs relative to the numbers who actually participate can help ensure that agencies can monitor and communicate key information on program access. To better understand participation in low-income programs, this report provides information on: (1) the proportion of those eligible who are participating in 12 selected low-income programs; (2) factors that influence participation in those programs; and (3) strategies used by federal, state, and local administrators to improve both access and integrity, and whether agencies monitor access by measuring participation rates."

Capital Financing: Potential Benefits of Capital Acquisition Funds Can Be Achieved through Simpler Means
A letter report issued by the Government Accountability Office with an abstract that begins "CAFs have been discussed as a new mechanism for financing federal capital assets. As envisioned, CAFs would have two goals. First, CAFs would potentially improve decision making by reflecting the annual cost for the use of capital in program budgets. Second, they would help ameliorate at the subunit level the effect of large increases in budget authority for capital projects (i.e., spikes), without forfeiting congressional controls requiring the full cost of capital assets to be provided up-front. Through discussions with budget experts and by working with two case studies, the Departments of Agriculture and of the Interior, we are able to describe in this report (1) how CAFs would likely operate, (2) the potential benefits and difficulties of CAFs, including alternative mechanisms for obtaining the benefits, and (3) several issues to weigh when considering implementation of CAFs."

NextGen Air Transportation System: FAA Has Made Some Progress in Midterm Implementation, but Ongoing Challenges Limit Expected Benefits
A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Aviation Administration (FAA) is pursuing key operational improvements to implement the Next Generation Air Transportation System (NextGen) in the "midterm," which is 2013 through 2018. These improvements focus on establishing Performance Based Navigation (PBN) procedures at key airports, but benefits could be limited in the midterm. PBN uses satellite-based guidance to improve air-traffic control routes (known as "procedures"). These procedures can deliver benefits to airlines, such as fuel savings and increased efficiency, particularly in congested airspace. To deliver benefits more quickly, FAA made trade-offs in selecting sites and in the scope of proposed improvements. For example, FAA is not implementing procedures that will trigger lengthy environmental reviews. These trade-offs, with which airlines and other stakeholders generally agree, will likely limit benefits from these PBN initiatives early in the midterm. FAA has also made some progress in other key operational improvement areas, such as upgrading traffic management systems and revising standards to improve aircraft flow in congested airspace. However, FAA has not fully integrated implementation of all of its operational improvement efforts at airports. Because of the interdependency of improvements, their limited integration could also …

All-Terrain Vehicles: How They Are Used, Crashes, and Sales of Adult-Sized Vehicles for Children's Use
A letter report issued by the Government Accountability Office with an abstract that begins "All-terrain vehicles (ATV), which are off-road motorized vehicles, usually with four tires, a straddle seat for the operator, and handlebars for steering control, have become increasingly popular. However, ATV fatalities and injuries have increased over the last decade and are a matter of concern to the Consumer Product Safety Commission (Commission), which oversees ATV safety, and to others. Many ATV crashes involving children occur when they are riding adult-sized ATVs. Manufacturers and distributors have agreed to use their best efforts to prevent their dealers from selling adult-sized ATVs for use by children under the age of 16. The Consumer Product Safety Improvement Act requires GAO to report on (1) how ATVs are used and the advantages of their use and (2) the nature, extent, and costs of ATV crashes. GAO addressed these topics by reviewing ATV use and crash data and by discussing these issues with Commission staff, industry officials, user groups, and safety stakeholders."

Aviation Safety: FAA Should Improve Usability of its Online Application System and Clarity of the Pilot's Medical Form
A letter report issued by the Government Accountability Office with an abstract that begins "Aerospace medical experts GAO interviewed generally agreed that the Federal Aviation Administration's (FAA) medical standards are appropriate and supported FAA's recent data-driven efforts to improve its pilot medical-certification process. Each year, about 400,000 candidates apply for a pilot's medical certificate and complete a medical exam to determine whether they meet FAA's medical standards. From 2008 through 2012, on average, about 90 percent of applicants have been medically certified by an FAA-designated aviation medical examiner (AME) at the time of their medical exam or by a Regional Flight Surgeon. Of the remaining applicants, about 8.5 percent have received a special issuance medical certificate (special issuance) after providing additional medical information to FAA. Approximately 1.2 percent were not medically certified to fly. According to an industry association, the special issuance process adds time and costs to the application process, in part, because applicants might not understand what additional medical information they need to provide to FAA. Officials from FAA's medical certification division have said that technological problems with the aging computer systems that support the medical certification process have contributed to delays in the special issuance process. FAA's …
