The effects of the maximum credible accident relative to the design of the containment shell are discussed. The maximum credible accident is defined. The thermal and hydraulic effects of the maximum credible accident on the reactor system were analyzed. The extent to which fuelrod cladding will melt was estimated. The amount of energy released from the reactor system by the escaping steam and water and by a possible chemical reaction was calculated along with the corresponding pressure rise inside the containment shell. The kinds, amounts, and total radioactivity of fission products released to the atmosphere of the containment shell after the core melts were predicted. (M.C.G.)

A letter report issued by the Government Accountability Office with an abstract that begins "Federal Reserve Banks fulfill the coin demand of the nation's depository institutions--which include commercial banks, savings and loan associations, and credit unions--by ordering new coins from the U.S. Mint and managing coins held in inventory at the Reserve Banks and in coin terminals. Reliably estimating the demand for coins and efficiently managing the inventory of circulated coins is important to ensure that depository institutions have enough coins to meet the public's demand and to avoid unnecessary coin production costs. Since late 2006, rising metal prices have driven the costs of producing pennies and nickels above the face values of the coins. This report addresses (1) the Reserve Banks' process for ordering and distributing coins to the nation's depository institutions and (2) the extent to which this process meets depository institutions' demand for coins. GAO interviewed officials responsible for coin distribution at each of the 12 Reserve Banks and met with representatives of 4 large operators of Federal Reserve coin terminals, 2 banking associations, the U.S. Mint, and the nation's largest coin recycling company. GAO also analyzed Reserve Bank data for fiscal years 1993 through 2007. Federal …

A letter report issued by the Government Accountability Office with an abstract that begins "In the 1990s, states sued major tobacco companies to obtain reimbursement for health impairments caused by the public's use of tobacco. In 1998, 46 states and four of the nation's largest tobacco companies signed a Master Settlement Agreement (MSA) that requires the tobacco companies to make annual payments to the states in perpetuity as reimbursement for past tobacco-related health care costs. The MSA commits the tobacco companies to pay the states approximately $206 billion over the first 25 years. Some of the states have arranged to receive upfront proceeds based on the amounts that tobacco companies owe by issuing bonds backed by future payments. The Farm Security and Rural Investment Act of 2002 requires GAO to report annually on the amount of MSA payments that states receive through fiscal year 2006. This fourth report provides information on (1) the payments the 46 states received in fiscal year 2004 and expect to receive in fiscal year 2005 and (2) states' allocations of these funds to various program categories and changes from prior years. To conduct this study, GAO surveyed the 46 states."

A letter report issued by the Government Accountability Office with an abstract that begins "The annual appropriation for the Community Development Block Grant (CDBG) program allows grantees to use up to 20 percent of program funds for planning, management, and administration (collectively referred to as "administration"). Specifically, grantees may use these funds for a range of activities, including general management, oversight, and coordination; fair housing activities; preparing community development plans; and policy planning. The Department of Housing and Urban Development (HUD) uses broad categories, such as "general program administration" and "fair housing activities," to record grantees' administrative expenses. According to HUD's data for the last decade, grantees primarily recorded their administrative expenses under the general program administration category, which includes staff salaries. Grantees GAO interviewed added that they also used administrative funds to cover general administrative costs such as supplies, training, and travel."

A letter report issued by the Government Accountability Office with an abstract that begins "Through its Veterans Health Administration (VHA), the Department of Veterans Affairs (VA) operates one of the largest health care systems in the country. In 1999, GAO reported that better management of VA's large inventory of aged capital assets could result in savings that could be used to enhance health care services for veterans. In response, VA initiated a process known as Capital Asset Realignment for Enhanced Services (CARES). Through CARES, VA sought to enhance veteran care by the appropriate sizing, upgrading, and locating of VA facilities. GAO was asked to examine the CARES process. Specifically, GAO examined (1) how CARES contributes to VHA's capital planning process, (2) the extent to which the CARES process considered capital asset alignment alternatives, and (3) the extent to which VA has implemented CARES decisions and how this implementation has helped VA carry out its mission. To address these issues, we analyzed CARES documents, interviewed VA officials, and conducted six site visits, among other things."

A letter report issued by the Government Accountability Office with an abstract that begins "GAO has reported on limitations in the management of U.S. low-level radioactive waste (LLRW). LLRW ranges from very low-activity to higher-activity waste. To identify potential approaches to overcome these limitations, GAO was asked to examine the extent to which other countries have (1) LLRW inventory databases, (2) timely removal of higher-activity LLRW from waste generator sites, (3) disposition options for all LLRW, and (4) requirements that LLRW generators have financial reserves to cover waste disposition costs, as well as any other approaches that might improve U.S. LLRW management. GAO primarily relied on a survey of 18 countries representing leading LLRW generators to identify their management approaches and to compare them with U.S. survey results and with approaches suggested by LLRW generators, disposal operators, and regulators in the United States."

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) has taken some steps to examine its headquarters resources for efficiencies, but additional opportunities for cost savings may exist by further consolidating organizations and centralizing functions. For purposes of the Secretary of Defense’s efficiency initiative, DOD components were asked to focus in particular on headquarters and administrative functions, support activities, and other overhead in their portfolios. DOD’s fiscal year 2012 budget request included several efficiencies related to headquarters organizations or personnel. GAO found that these efficiencies generally fell into two categories: (1) consolidating or eliminating organizations based on geographic proximity or span of control and (2) centralizing overlapping functions and services. The DOD efficiencies that GAO reviewed to reduce headquarters resources are expected by DOD to save about $2.9 billion through fiscal year 2016, less than 2 percent of the $178 billion in savings DOD projected departmentwide. GAO’s work indicates that DOD may be able to find additional efficiencies by further examining opportunities to consolidate organizations or centralize functions at headquarters. DOD may not have identified all areas where reductions in headquarters personnel and operating costs could be achieved because the …

A letter report issued by the Government Accountability Office with an abstract that begins "The Logistics Civil Augmentation Program (LOGCAP) is an Army program that plans for the use of a private-sector contractor to support worldwide contingency operations. Examples of the types of support available include laundry and bath, food service, sanitation, billeting, maintenance, and power generation. LOGCAP has been used extensively to support U.S. forces in recent operations in southwest Asia, with more than $15 billion in estimated work as of January 2005. While we issued two reports on LOGCAP since 1997 that made recommendations to improve the Army's management of the contract, broader issues on coordination of LOGCAP's contract functions were beyond the scope of our earlier work. This report assesses the extent to which the Army is taking action to improve the management and oversight of LOGCAP and whether further opportunities for using this contract effectively exist."

This report provides background information on political and economic conditions in the Dominican Republic, as well as an overview of some of the key issues in U.S.-Dominican relations

A letter report issued by the General Accounting Office with an abstract that begins "Future demographic trends include a doubling of the nation's retiree population and only modest labor force growth, leading to concerns about retirement income adequacy for future generations. Credible projections of the effects of policy proposals on federal spending and future retirees' income are necessary. Because adequate data is critical to the analysis of retirement income and wealth, GAO was asked to identify data improvements that experts say are a priority for the study of retirement income and wealth, as well as factors limiting efforts to obtain the needed information."

A letter report issued by the General Accounting Office with an abstract that begins "In May 2002, GAO reported on breakdowns in purchasing controls at the Federal Aviation Administration's (FAA) Alaskan Region that resulted in improper and wasteful purchases. Many of the weaknesses were associated with the use of government credit cards--referred to as purchase cards--and raised concerns that similar problems might exist FAA-wide. As a result, GAO was asked to determine whether FAA's purchase card controls reasonably ensured that purchases were proper, at a reasonable cost, and for valid government needs. GAO also assessed whether assets bought with purchase cards were being properly safeguarded and recorded."

Iron dominated magnets are characterized in the limit of infinite permeability by a pole shape that is a magnetic equipotential. Deviations from this ideal because of finite permeability are associated with differences in path length, local saturation, flux concentration in slotted pole if crenellation is used, and sub surface voids. For moderate field levels the variation in flux path length throughout the iron lowers the magnetic potential on the iron surface more for the longer paths. As the excitation increases the permeability is lowered in regions of high flux density. Crenellation in this region offers some degree of control over the permeability by concentrating the flux. To a lesser degree sub surface voids can be used to control the reluctance of a flux path. The net result suggests that the shape of the effective air gap can be adjusted to be a magnetic equipotential sensibly equivalent to the ideal pole shape for infinite permeability.

Social security benefits are not paid for the month in which a recipient dies. Legislation is routinely introduced that would either pay the full amount of the benefits for the month of death or pro-rate the benefits based on the proportion of the month that the recipient was alive.

Each year, more than 50 million vehicles reach the end of their service life throughout the world. More than 95% of these vehicles enter a comprehensive recycling infrastructure that includes auto parts recyclers/dismantlers, remanufacturers, and material recyclers (shredders). Today, about 75% of automotive materials are profitably recycled via (1) parts reuse and parts and components remanufacturing and (2) ultimately by the scrap processing (shredding) industry. The process by which the scrap processors recover metal scrap from automobiles involves shredding the obsolete automobiles, along with other obsolete metal-containing products (such as white goods, industrial scrap, and demolition debris), and recovering the metals from the shredded material. The single largest source of recycled ferrous scrap for the iron and steel industry is obsolete automobiles. The non-metallic fraction that remains after the metals are recovered from the shredded materials (about 25% of the weight of the vehicle)--commonly called shredder residue--is disposed of in landfills. Over the past 10 to 15 years, a significant amount of research and development has been undertaken to enhance the recycle rate of end-of-life vehicles (ELVs), including enhancing dismantling techniques and improving remanufacturing operations. However, most of the effort has focused on developing technology to recover materials, such as …

The 100-B-14:2 subsite encompasses the former sanitary sewer feeder lines associated with the 1607-B2 and 1607-B7 septic systems. Feeder lines associated with the 185/190-B building have also been identified as the 100-B-14:8 subsite, and feeder lines associated with the 1607-B7 septic system have also been identified as the 100-B-14:9 subsite. These two subsites have been administratively cancelled to resolve the redundancy. The results of verification sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.

Fossil fuel combustion, deforestation, and biomass burning are the dominant contributors to increasing atmospheric carbon dioxide (CO{sub 2}) concentrations and global warming. Many approaches to mitigating CO{sub 2} emissions are being pursued, and among the most promising are terrestrial and geologic carbon sequestration. Recent advances in ecology and microbial biology offer promising new possibilities for enhancing terrestrial and geologic carbon sequestration. A workshop was held October 29, 2007, at Lawrence Berkeley National Laboratory (LBNL) on Biologically Enhanced Carbon Sequestration (BECS). The workshop participants (approximately 30 scientists from California, Illinois, Oregon, Montana, and New Mexico) developed a prioritized list of research needed to make progress in the development of biological enhancements to improve terrestrial and geologic carbon sequestration. The workshop participants also identified a number of areas of supporting science that are critical to making progress in the fundamental research areas. The purpose of this position paper is to summarize and elaborate upon the findings of the workshop. The paper considers terrestrial and geologic carbon sequestration separately. First, we present a summary in outline form of the research roadmaps for terrestrial and geologic BECS. This outline is elaborated upon in the narrative sections that follow. The narrative sections start with the …

In the coming decades, the United States and the entire world will need energy supplies to meet the growing demands due to population increase and increase in consumption due to global industrialization. One of the reactor system concepts, the Very High Temperature Reactor (VHTR), with helium as the coolant, has been identified as uniquely suited for producing hydrogen without consumption of fossil fuels or the emission of greenhouse gases [Generation IV 2002]. The U.S. Department of Energy (DOE) has selected this system for the Next Generation Nuclear Plant (NGNP) Project, to demonstrate emissions-free nuclear-assisted electricity and hydrogen production within the next 15 years. The NGNP reference concepts are helium-cooled, graphite-moderated, thermal neutron spectrum reactors with a design goal outlet helium temperature of {approx}1000 C [MacDonald et al. 2004]. The reactor core could be either a prismatic graphite block type core or a pebble bed core. The use of molten salt coolant, especially for the transfer of heat to hydrogen production, is also being considered. The NGNP is expected to produce both electricity and hydrogen. The process heat for hydrogen production will be transferred to the hydrogen plant through an intermediate heat exchanger (IHX). The basic technology for the NGNP has …
