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 "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 "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 …

The mathematical modeling of systems often requires the use of both nonlinear and discrete components. Problems involving both discrete and nonlinear components are known as mixed-integer nonlinear programs (MINLPs) and are among the most challenging computational optimization problems. This research project added to the understanding of this area by making a number of fundamental advances. First, the work demonstrated many novel, strong, tractable relaxations designed to deal with non-convexities arising in mathematical formulation. Second, the research implemented the ideas in software that is available to the public. Finally, the work demonstrated the importance of these ideas on practical applications and disseminated the work through scholarly journals, survey publications, and conference presentations.

This report describes the modeling of a PWR fuel assembly under dynamic shock loading in support of the Sandia National Laboratories (SNL) shaker test campaign. The focus of the test campaign is on evaluating the response of used fuel to shock and vibration loads that a can occur during highway transport. Modeling began in 2012 using an LS-DYNA fuel assembly model that was first created for modeling impact scenarios. SNL’s proposed test scenario was simulated through analysis and the calculated results helped guide the instrumentation and other aspects of the testing. During FY 2013, the fuel assembly model was refined to better represent the test surrogate. Analysis of the proposed loads suggested the frequency band needed to be lowered to attempt to excite the lower natural frequencies of the fuel assembly. Despite SNL’s expansion of lower frequency components in their five shock realizations, pretest predictions suggested a very mild dynamic response to the test loading. After testing was completed, one specific shock case was modeled, using recorded accelerometer data to excite the model. Direct comparison of predicted strain in the cladding was made to the recorded strain gauge data. The magnitude of both sets of strain (calculated and recorded) are …

Oxy-fuel combustion has been used previously in a wide range of industrial applications. Oxy- combustion is carried out by burning a hydrocarbon fuel with oxygen instead of air. Flames burning in this configuration achieve higher flame temperatures which present opportunities for significant efficiency improvements and direct capture of CO{sub 2} from the exhaust stream. In an effort to better understand and characterize the fundamental flame characteristics of oxy-fuel combustion this research presents the experimental measurements of flame stability of various oxyfuel flames. Effects of H{sub 2} concentration, fuel composition, exhaust gas recirculation ratio, firing inputs, and burner diameters on the flame stability of these fuels are discussed. Effects of exhaust gas recirculation i.e. CO{sub 2} and H{sub 2}O (steam) acting as diluents on burner operability are also presented. The roles of firing input on flame stability are then analyzed. For this study it was observed that many oxy-flames did not stabilize without exhaust gas recirculation due to their higher burning velocities. In addition, the stability regime of all compositions was observed to decrease as the burner diameter increased. A flashback model is also presented, using the critical velocity gradient g{sub F}) values for CH{sub 4}-O{sub 2}-CO{sub 2} flames. The scaling …

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."

This report describes the results of the electrochemical testing performed on tank 241-SY-102 (SY-102) grab samples that were collected in support of corrosion mitigation. The objective of the work presented here was to determine corrosion resistance of tank SY-102 to the grab samples collected using electrochemical methods up to 50°C as well as to satisfy data quality objectives. Grab samples were collected at multiple elevations from Riser 003. The electrochemical corrosion testing was planned to consist of linear polarization resistance testing (LPR) and cyclic potentiodynamic polarization (CPP) testing at 50°C. The temperature would be lowered to 40 °C and the test repeated if the CPP curve indicated pitting corrosion at 50°C. Ifno pitting was indicated by the CPP curve, then a duplicate scan would be repeated at 50°C to confirm the first result. The testing would be complete if the duplicate CPP scan was consistent with the first. This report contains the CPP results of the testing of grab sample 2SY-12-03 and 2SY-12-03DUP composite sample tested under these conditions. There was no indication of pitting at 50°C, and the duplicate scan was in agreement with the first scan. Since no further testing was required, a third scan with a shorter …

The Cooperative Research Network (CRN) of the National Rural Electric Cooperative Association (NRECA) has identified GridLAB-D as a tool that would provide significant benefit to its member utilities. However, they have also noted that the complexity of the tool would be a significant barrier for adoption. As can often happen in complex simulation environments, as the available capabilities and flexibility increases, the usability of the software decreases except for a few “power” users; this is not unique to GridLAB-D. While GridLAB-D has expanded to a considerable user base, with a few notable exceptions (e.g., American Electric Power) most users are focused on research and development. As a result, NRECA/CRN has proposed an Open Modeling Framework (OMF) designed to make the capabilities of GridLAB-D, and other advanced grid tools, available via a web interface. This will allow utility users to access many of the capabilities of GridLAB-D, with little to no knowledge of the tool itself. Other components will be layered over the simulation engines to provide the user with business support functions, allowing full business case scenarios to be created from the technical data generated within the simulations. Because of the open availability and potential national benefit of the OMF, …
