The University of Tennessee Space Institute (UTSI) reports on significant activity, task status, planned research, testing, development, and conclusions for the Magnetohydrodynamics (MHD) Coal-Fired Flow Facility (CFFF) and the Research and Development Laboratory. Although slowed by incessant rain during several days, work on the CFFF Bid Packages progressed to nearly 100 percent completion, excluding later punchlist items. On the quench system, the cyclone separator was delivered to UTSI, and under Downstream Components, the secondary combustor was received and the radiant slagging furnace was emplaced at the CFFF. Water quality analysis of Woods Reservoir provided the expected favorable results, quite similar to last year's. Generator experiments describing local current distribution are reported along with behavior under conditions of imposed leakage. Also, during the Quarter, the shelter for the cold flow modeling facility was constructed and circuits installation begun. A jet turbine combustor was tested for use as a vitiation burner. Samples taken from the exhaust duct, besides other applications, show that the refractories used are performing well in alleviating heat loss while exhibiting acceptable degredation. A new resistive power take-off network was designed and implemented.

The use of carbonaceous adsorbents is limited by irreversible adsorption of some compounds so the use of supercritical pentane as an extracting solvent was examined. Carbon black appeared to be broken down slowly, but continuously, by the penane. To see if other types of carbon behaved similarly, high purity graphite, technical grade graphites, active carbons, and charcoals were examined. The extracts were characterized by uv spectroscopy, packed column chromatography using flame ionization and flame photometric detectors, and capillary GC/MS. The extracts were characteristic for each class of carbonaceous material. The high purity graphite yielded large, polycyclic aromatic compounds; the technical grade graphites yielded alkanes and alkyl-substituted benzenes and naphthalenes; the active carbons yielded alkanes, dienes, and small amounts of alkyl-substituted benzenes; and the charcoals yielded almost entirely alkanes in small amounts.

Disposal of high-level radioactive wastes is a major environmental problem influencing further development of nuclear energy in this country. Salt domes in the Gulf Coast Basin are being investigated as repository sites. A major concern is geologic and hydrologic stability of candidate domes and potential transport of radionuclides by groundwater to the biosphere prior to their degradation to harmless levels of activity. This report conceptualizes a regional geohydrologic model for transport of radionuclides from a salt dome repository. The model considers transport pathways and the physical and chemical changes that would occur through time prior to the radionuclides reaching the biosphere. Necessary, but unknown inputs to the regional model involve entry and movement of fluids through the repository dome and across the dome-country rock interface and the effect on the dome and surrounding strata of heat generated by the radioactive wastes.

A nationwide examination was made of grassroots energy conservation programs related to transportation. Information compiled from civic groups, trade associations, and corporations is included on driver awareness/mass transit; travel; and ride sharing. It is concluded that a willingness by the public to cooperate in transportation energy conservation exists and should be exploited. (LCL)

In analyzing the behavior of a vacuum arc during interruption , a mathematical model has been set up to describe the events occurring in the interelectrode gap during interruption. The reliability of the results obtained using such a model depends on the accuracy of the initial assumptions made in setting up the model equations. Previous results obtained from the model analysis were compared to experimental data and it was found that there was a discrepancy close to current zero. To improve our model results some of the original model assumptions have been reconsidered in order to make the model more closely represent the physical reality of a vacuum arc.

A letter report issued by the Government Accountability Office with an abstract that begins "In accordance with Public Law 108-324, GAO is required to audit the reimbursement of up to $70 million of appropriated funds to the American Red Cross (Red Cross) for disaster relief associated with 2004 hurricanes Charley, Frances, Ivan, and Jeanne. The audit was performed to determine if (1) the Federal Emergency Management Agency (FEMA) established criteria and defined allowable expenditures to ensure that reimbursement claims paid to the Red Cross met the purposes of the law, (2) reimbursement funds paid to the Red Cross did not duplicate funding by other federal sources, (3) reimbursed funds assisted only eligible states and territories for disaster relief, and (4) reimbursement claims were supported by adequate documentation. The 2004 hurricane season was one of the most destructive in U.S. history. Fifteen named storms resulted in 21 federal disaster declarations. Four hurricanes affecting 19 states and 2 U.S. territories from August 13 through September 26, 2004, triggered the nation's biggest natural-disaster response up to that time. Over 150 deaths and $45 billion of estimated property damage are attributed to hurricanes Charley, Frances, Ivan, and Jeanne in the United States alone. Through …

A letter report issued by the Government Accountability Office with an abstract that begins "Federal agencies need to exercise strong oversight to promote effectiveness and efficiency and prevent waste, fraud, and abuse--especially in a federal procurement program such as this, which is exempt from full and open competition requirements. However, although the AbilityOne Commission is ultimately responsible for overseeing the program, the Commission cannot control how CNAs (1) spend their funds, (2) set and manage their performance goals, or (3) set and implement governance policies and other internal controls. The Commission's authority to direct CNA budget priorities--including how much they compensate their executives and the level and growth of their reserves--is limited. As independent entities, the CNAs are responsible for determining their spending. Most of their money comes from fees they charge their affiliates as a percent of revenue earned from AbilityOne contracts. Moreover, the Commission does not have sufficient authority to set CNA performance and governance standards, so it depends on the CNAs to set and enforce such standards. Although the CNAs have instituted their own internal controls, the Commission does not have procedures to monitor alleged CNA control violations, nor is there an inspector general to provide independent …

A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Energy (DOE) has long suffered from contract and management oversight weaknesses. Since 1990 DOE contract management has been on GAO's list of programs at high risk for fraud, waste, abuse, and mismanagement. In 2003 DOE's Office of Science (Science) unveiled its 20-year plan to acquire and upgrade potentially costly research facilities. In light of DOE's history and the potential cost of this ambitious plan, GAO was asked to examine Science's project management performance. GAO determined (1) the extent to which Science has managed its projects within cost and schedule targets, (2) the factors affecting project management performance, and (3) challenges that may affect Science's future performance. GAO reviewed DOE and Science's project management guidance and 42 selected Science projects and also interviewed DOE and laboratory officials."

A letter report issued by the General Accounting Office with an abstract that begins "Strategic workforce planning helps ensure that agencies have the right people with the right skills in the right positions to carry out the agency mission both in the present and future. The Internal Revenue Service's (IRS) Taxpayer Education and Communication (TEC) unit within its Small Business and Self- Employed Division assists some 45 million small business and self-employed taxpayers. Given the number of taxpayers it is to assist and changes in its priorities and strategies, GAO was asked to determine whether TEC has a workforce plan that conforms to critical elements for what should be in a plan and how it should be developed and implemented."

A letter report issued by the Government Accountability Office with an abstract that begins "The financing of the $299 billion Medicaid program is shared between the federal government and states. States pay qualified providers for covered Medicaid services and receive federal matching funds from the Department of Health & Human Services' (HHS) Centers for Medicare & Medicaid Services (CMS) for expenditures authorized in their state Medicaid plans. In addition to these standard Medicaid payments, most states make supplemental payments to certain providers, which are also matched by federal funds. GAO was asked for information about Medicaid supplemental payments. GAO examined (1) what information states report about supplemental payments on Medicaid expenditure reports and (2) in selected states, how much was distributed as supplemental payments, to what types of providers, and for what purposes. GAO analyzed CMS's Medicaid expenditure reports and surveyed five states that make large supplemental payments."

A letter report issued by the Government Accountability Office with an abstract that begins "Military operations in support of the Global War on Terrorism, particularly those in Iraq and Afghanistan, have challenged the Department of Defense's (DOD) ability to provide needed ground forces. Section 354 of the Fiscal Year 2008 National Defense Authorization Act directed GAO to report on a number of military readiness issues. In this report, GAO addresses (1) the extent to which DOD's use of nonstandard forces to meet ground force requirements has impacted the force and (2) the extent to which DOD has faced challenges in managing the training and use of these forces, and taken steps to address any challenges. To address these objectives, GAO analyzed DOD policies, guidance, and data and interviewed department, joint, combatant command, and service officials as well as trainers and over 300 deploying, deployed, and redeploying servicemembers."

A letter report issued by the Government Accountability Office with an abstract that begins "Wildland fires burn millions of acres each year, requiring substantial investments of firefighting assets. Since 2000, federal suppression costs alone have averaged more than $1 billion annually. Wildland fires can burn or threaten both federal and nonfederal lands and resources, including homes in or near wildlands, an area commonly called the wildland-urban interface. Cooperative agreements between federal and nonfederal firefighting entities provide the framework for working together and sharing costs. GAO was asked to (1) review how federal and nonfederal entities share the costs of suppressing wildland fires that burn or threaten both of their lands and resources and (2) identify any concerns that these entities may have with the existing cost-sharing framework."

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Deposit Insurance Corporation (FDIC) has a demanding responsibility enforcing banking laws, regulating financial institutions, and protecting depositors. Effective information security controls are essential to ensure that FDIC systems and information are adequately protected from inadvertent misuse, fraudulent, or improper disclosure. As part of its audit of FDIC's 2007 financial statements, GAO assessed (1) the progress FDIC has made in mitigating previously reported information security weaknesses and (2) the effectiveness of FDIC's controls in protecting the confidentiality, integrity, and availability of its financial systems and information. To do this, GAO examined security policies, procedures, reports, and other documents; observed controls over key financial applications; and interviewed key FDIC personnel."

A letter report issued by the Government Accountability Office with an abstract that begins "Government agencies have a long-standing obligation under the Privacy Act of 1974 to protect the privacy of individuals about whom they collect personal information. A number of additional laws have been enacted in recent years directing agency heads to designate senior officials as focal points with overall responsibility for privacy. GAO was asked to (1) describe laws and guidance that set requirements for senior privacy officials within federal agencies, and (2) describe the organizational structures used by agencies to address privacy requirements and assess whether senior officials have oversight over key functions. To achieve these objectives, GAO analyzed the laws and related guidance and analyzed policies and procedures relating to key privacy functions at 12 agencies."

A letter report issued by the Government Accountability Office with an abstract that begins "As part of its Disability Compensation program, the Department of Veterans Affairs (VA) provides Individual Unemployability (IU) benefits to veterans of any age who are unemployable because of service-connected disabilities. Over the last decade, the number of IU beneficiaries and benefit costs have more than tripled. In 2005, about 220,000 veterans received an estimated $3.1 billion in IU benefits. In response to a congressional request, GAO assessed VA's management of IU benefits. This report (1) examines the added value of IU benefits for veterans of selected ages and disability ratings, (2) assesses the criteria, guidance, and procedures used for initial decision making, (3) assesses VA's ongoing eligibility enforcement procedures, and (4) compares VA's decision-making and enforcement procedures with those used by other disability programs."

A letter report issued by the Government Accountability Office with an abstract that begins "Effective tax rates (ETR) differ from statutory tax rates in that they attempt to measure taxes paid as a proportion of economic income, while statutory rates indicate the amount of tax liability (before any credits) relative to taxable income, which is defined by tax law and reflects tax benefits and subsidies built into the law. Lacking access to detailed data from tax returns, most researchers have estimated ETRs based on data from financial statements. A common measure of tax liability used in past estimates has been the current tax expense--either federal only or worldwide (which comprises federal, foreign, and U.S. state and local income taxes). The most common measure of income for these estimates has been some variant of pretax net book income. GAO was able to compare book tax expenses to tax liabilities actually reported on corporate income tax returns."

A letter report issued by the Government Accountability Office with an abstract that begins "The John Warner National Defense Authorization Act for Fiscal Year 2007 included provisions regarding mental health concerns and traumatic brain injury (TBI). GAO addressed these issues as required by the Act. In this report GAO discusses (1) DOD efforts to implement pre-deployment mental health screening; (2) how post-deployment mental health referrals are tracked; and (3) screening requirements for mild TBI. GAO selected the Army, Marine Corps, and Army National Guard for the review. GAO reviewed documents and interviewed DOD officials and conducted site visits to three military installations where the pre-deployment health assessment was being conducted."

A letter report issued by the Government Accountability Office with an abstract that begins "According to experts, agency officials, and specialists, much is known about the use of chemical dispersants on the surface of the water, but gaps remain in several research areas. For example, experts generally agreed that there is a basic understanding of the processes that influence where and how oil travels through the water, but that more research was needed to quantify the actual rate at which dispersants biodegrade. In addition, all the experts GAO spoke with said that little is known about the application and effects of dispersants applied subsurface, noting that specific environmental conditions, such as higher pressures, may influence dispersants’ effectiveness. Knowledge about the use and effectiveness of dispersants in the Arctic is also limited, with less research conducted on dispersant use there than in temperate or tropical climates. For example, one expert noted that more research is needed on biodegradation rates for oil in the Arctic because the cold temperature may slow the process down."

A letter report issued by the Government Accountability Office with an abstract that begins "The scope of the Nuclear Regulatory Commission's (NRC) license renewal process focuses on managing the effects of aging on a reactor and its associated systems, structures, and components (i.e. safety) and assessing certain potential environmental impacts of extending a reactor's operating-life. As a result, reviews done as part of this process are not required to address as many topics as reviews for initial licensing, which include security and emergency planning."

A letter report issued by the Government Accountability Office with an abstract that begins "Historically, the Securities and Exchange Commission’s (SEC) oversight of the Financial Industry Regulatory Authority’s (FINRA) programs and operations varied, with some programs and operations receiving regular oversight and others receiving limited or no oversight. Through its inspection process, SEC conducted routine and special inspections of various aspects of FINRA regulatory programs, including examinations, surveillance, and enforcement programs. SEC has also conducted routine inspections of FINRA’s advertising and arbitration programs but not as frequently as it had planned. SEC has also regularly reviewed FINRA proposed rule changes that are subject to SEC approval to determine consistency with the Securities Exchange Act of 1934 and related rules and regulations. However, neither SEC nor FINRA conducts retrospective reviews of FINRA’s rules. GAO and others have reported on the usefulness of retrospective reviews as they allow agencies to assess the effectiveness of their rules, and some federal financial regulators, including SEC, have begun pursuing plans to conduct retrospective reviews of their rules in light of a recent executive order that encourages independent regulatory agencies to do so. By not conducting these reviews, FINRA may be missing an opportunity to systematically …

A letter report issued by the Government Accountability Office with an abstract that begins "While the Export-Import Bank (Ex-Im) Business Plan reported that Ex-Im's exposure limits were appropriate, the forecasting process used to reach this conclusion has weaknesses. Congress increased the Ex-Im exposure limit--the limit on Ex-Im's total aggregate outstanding amount of financing--to $120 billion in 2012, with provisions for additional increases to $130 billion in 2013 and $140 billion in 2014. Although Ex-Im's forecast model is sensitive to key assumptions, GAO found that Ex-Im did not reassess these assumptions to reflect changing conditions or conduct sensitivity analyses to assess and report the range of potential outcomes. GAO used historical data in lieu of these assumptions and found that Ex-Im's forecast of exposure could be higher than the limit set by Congress for 2014. GAO's cost guidance calls for agencies' assumptions and forecasts to be supported by historical data and experience, and a sensitivity analysis, which can assess the effect of changes in assumptions. Because Ex-Im has not taken these steps, the reliability of its forecasts is diminished. This is of particular concern because Ex-Im projects that its outstanding financing in the future will be closer to its exposure limit …
