A letter report issued by the Government Accountability Office with an abstract that begins "Internal Revenue Service (IRS) data are not sufficient for identifying who claims a tax expenditure and how much they claim for $492 billion or almost half the dollar value of all tax expenditures that GAO examined. Such basic data are not available at IRS for tax expenditures because they do not have their own line item on a tax form. This included $102 billion of tax expenditures that were not on tax forms, such as the exclusion of interest on life insurance savings, and $390 billion of tax expenditures that were on tax forms but did not have their own line items, such as the credit for holding clean renewable energy bonds which is aggregated with other credits on a single line item."

A letter report issued by the Government Accountability Office with an abstract that begins "The Center for Consumer Information and Insurance Oversight (CCIIO) discontinued enrollment in the Early Retiree Reinsurance Program (ERRP) in early 2011 and stopped most program reimbursements the following year to keep spending within the $5 billion ERRP appropriation. Specifically, anticipating exhaustion of funds, CCIIO stopped ERRP enrollment in May 2011. According to CCIIO officials, CCIIO suspended making reimbursements to plan sponsors in September 2012, as reimbursements had reached the $4.7 billion cap established for paying claims under the original appropriation, and the remainder was reserved for administrative expenses. When the cap was reached, significant demand for the program remained with 5,699 ERRP reimbursement requests left outstanding that accounted for about $2.5 billion in unpaid claims. CCIIO officials told GAO that they planned to pay some of the outstanding reimbursement requests by redistributing any overpayments recovered from plan sponsors--when, for example a plan receives a rebate that lowers the total cost of a prior claim--as well as money recovered from program audits. As of January 2013, officials told GAO that CCIIO had recovered a total of $54 million and redistributed $20.7 million of this amount."

A letter report issued by the Government Accountability Office with an abstract that begins "According to the Department of Health and Human Services (HHS), about 60 percent of the chemical, biological, radiological, and nuclear (CBRN) medical countermeasures in the Strategic National Stockpile (SNS) have been approved for children, but in many instances approval is limited to specific age groups. In addition, about 40 percent of the CBRN countermeasures have not been approved for any pediatric use. Furthermore, some of the countermeasures have not been approved to treat individuals for the specific indications for which they have been stockpiled. For example, ciprofloxacin is stockpiled in the SNS for the treatment of anthrax, plague, and tularemia, but is not approved for these indications. Countermeasures may be used to treat unapproved age groups or indications under an emergency use authorization (EUA) or an Investigational New Drug (IND) application submitted to the Food and Drug Administration (FDA)."

A letter report issued by the Government Accountability Office with an abstract that begins "DOD and the International Security Assistance Force (ISAF) have defined the mission and broad goals for Security Force Assistance (SFA) advisor teams; however, teams varied in the extent to which their approaches for developing their Afghan National Security Force (ANSF) units identified activities based on specific objectives or end states that were clearly linked with established goals. SFA guidance states that to be successful, advisors must have an end or goal in mind, and establish objectives that support higher-command plans. Theater commanders have outlined goals aimed at strengthening specific capabilities such as logistics, and it is largely left to the teams to then develop their approach for working with their counterparts. GAO found some advisor teams had developed structured advising approaches drawing from these goals, such as identifying monthly objectives and milestones for their team. Other teams GAO met with used less structured approaches, such as relying on interactions with ANSF counterparts to identify priorities and using this input to develop activities on an ad hoc basis, rather than as part of a longer-term, more structured approach to achieve broad goals. Officials from several teams stated …

The purpose of this project was to develop a compact, modular multi-channel x-ray detector with integrated electronics. This detector, based upon emerging silicon drift detector (SDD) technology, will be capable of high data rate operation superior to the current state of the art offered by high purity germanium (HPGe) detectors, without the need for liquid nitrogen. In addition, by integrating the processing electronics inside the detector housing, the detector performance will be much less affected by the typically noisy electrical environment of a synchrotron hutch, and will also be much more compact than current systems, which can include a detector involving a large LN2 dewar and multiple racks of electronics. The combined detector/processor system is designed to match or exceed the performance and features of currently available detector systems, at a lower cost and with more ease of use due to the small size of the detector. In addition, the detector system is designed to be modular, so a small system might just have one detector module, while a larger system can have many – you can start with one detector module, and add more as needs grow and budget allows. The modular nature also serves to simplify repair. In …

The Department of Energy – Savannah River (DOE-SR) has provided direction to Savannah River Remediation (SRR) to maintain fissile concentration in glass below 897 g/m{sup 3}. In support of that guidance, the Savannah River National Laboratory (SRNL) provided a technical basis and a supporting Microsoft® Excel® spreadsheet for the evaluation of fissile loading in Sludge Batch 5 (SB5), Sludge Batch 6 (SB6), Sludge Batch 7a (SB7a), and Sludge Batch 7b (SB7b) glass based on the iron (Fe) concentration in glass as determined by the measurements from the Slurry Mix Evaporator (SME) acceptability analysis. SRR has since requested that the necessary density information be provided to allow SRR to update the Excel® spreadsheet so that it may be used to maintain fissile concentration in glass below 897 g/m{sup 3} during the processing of Sludge Batch 8 (SB8). One of the primary inputs into the fissile loading spreadsheet includes an upper bound for the density of SB8-based glasses. Thus, these bounding density values are to be used to assess the fissile concentration in this glass system. It should be noted that no changes are needed to the underlying structure of the Excel-based spreadsheet to support fissile assessments for SB8. However, SRR should …

The overall project objective is to develop and demonstrate a polymer electrolyte membrane fuel cell combined heat and power (PEMFC CHP) system that provides the foundation for commercial, mass produced units which achieve over 40% electrical efficiency (fuel to electric conversion) from 50-100% load, greater than 70% overall efficiency (fuel to electric energy + usable waste heat energy conversion), have the potential to achieve 40,000 hours durability on all major process components, and can be produced in high volumes at under $400/kW (revised to $750/kW per 2011 DOE estimates) capital cost.

Theory, computations, and experimental apparatus are presented that describe and are intended to confirm novel properties of a coaxial two-channel dielectric wake field accelerator. In this configuration, an annular drive beam in the outer coaxial channel excites multimode wakefields which, in the inner channel, can accelerate a test beam to an energy much higher than the energy of the drive beam. This high transformer ratio is the result of judicious choice of the dielectric structure parameters, and of the phase separation between drive bunches and test bunches. A structure with cm-scale wakefields has been build for tests at the Argonne Wakefield Accelerator Laboratory, and a structure with mm-scale wakefields has been built for tests at the SLAC FACET facility. Both tests await scheduling by the respective facilities.

Off-road concerns are related to the effects of shock and vibration and air quality on fuel cell power requirements. Mechanical stresses on differing material makeup and mass distribution within the system may render some components susceptible to impulse trauma while others may show adverse effects from harmonic disturbances or broad band mechanical agitation. One of the recognized challenges in fuel cell systems air purification is in providing a highly efficient particulate and chemical filter with minimal pressure drop. PEM integrators do not want additional parasitic loads added to the system as compensation for a highly efficient yet highly restrictive filter. Additionally, there is challenge in integrating multiple functions into a single air intake module tasked with effectively filtering high dust loads, diesel soot, pesticides, ammonias, and other anticipated off-road contaminants. This project has investigated both off-road associated issues cumulating in the prototype build and testing of two light duty off-road vehicles with integrated fuel cell power plant systems.

Final Scientific/Technical Report for Project entitled "Mechanism of Uranium Reduction by Shewanella oneidensis"

The goals of this project are to develop new, scalable, high-fidelity algorithms for atomic-level simulations and program transformations that automatically restructure existing applications, enabling them to scale forward to Petascale systems and beyond. The techniques enable legacy MPI application code to exploit greater parallelism though increased latency hiding and improved workload assignment. The techniques were successfully demonstrated on high-end scalable systems located at DOE laboratories. Besides the automatic MPI program transformations efforts, the project also developed several new scalable algorithms for ab-initio molecular dynamics, including new massively parallel algorithms for hybrid DFT and new parallel in time algorithms for molecular dynamics and ab-initio molecular dynamics. These algorithms were shown to scale to very large number of cores, and they were designed to work in the latency hiding framework developed in this project. The effectiveness of the developments was enhanced by the direct application to real grand challenge simulation problems covering a wide range of technologically important applications, time scales and accuracies. These included the simulation of the electronic structure of mineral/fluid interfaces, the very accurate simulation of chemical reactions in microsolvated environments, and the simulation of chemical behavior in very large enzyme reactions.

For many decades, various radiation detecting material have been extensively researched, to find a better material or mechanism for radiation sensing. Recently, there is a growing need for a smaller and effective material or device that can perform similar functions of bulkier Geiger counters and other measurement options, which fail the requirement for easy, cheap and accurate radiation dose measurement. Here arises the use of thin film chalcogenide glass, which has unique properties of high thermal stability along with high sensitivity towards short wavelength radiation. The unique properties of chalcogenide glasses are attributed to the lone pair p-shell electrons, which provide some distinctive optical properties when compared to crystalline material. These qualities are derived from the energy band diagram and the presence of localized states in the band gap. Chalcogenide glasses have band tail states and localized states, along with the two band states. These extra states are primarily due to the lone pair electrons as well as the amorphous structure of the glasses. The localized states between the conductance band (CB) and valence band (VB) are primarily due to the presence of the lone pair electrons, while the band tail states are attributed to the Van der Waal’s forces …

Microbial Tc(VII) reduction is an attractive alternative strategy for bioremediation of technetium-contaminated subsurface environments. Traditional ex situ remediation processes (e.g., adsorption or ion exchange) are often limited by poor extraction efficiency, inhibition by competing ions and production of large volumes of produced waste. Microbial Tc(VII) reduction provides an attractive alternative in situ remediation strategy since the reduced end-product Tc(IV) precipitates as TcO2, a highly insoluble hydrous oxide. Despite its potential benefits, the molecular mechanism of microbial Tc(VII) reduction remains poorly understood. The main goal of the proposed DOENABIR research project is to determine the molecular mechanism of microbial Tc(VII) reduction. Random mutagenesis studies in our lab have resulted in generation of a set of six Tc(VII) reduction-deficient mutants of Shewanella oneidensis. The anaerobic respiratory deficiencies of each Tc(VII) reduction-deficient mutant was determined by anaerobic growth on various combinations of three electron donors and 14 terminal electron acceptors. Results indicated that the electron transport pathways to Tc(VII), NO3 -, Mn(III) and U(VI) share common structural or regulatory components. In addition, we have recently found that wild-type Shewanella are also able to reduce Tc(IV) as electron acceptor, producing Tc(III) as an end-product. The recent genome sequencing of a variety of technetium-reducing bacteria …

Strip Effluent Hold Tank (SEHT) and Decontaminated Salt Solution Hold Tank (DSSHT) samples from several of the ''microbatches'' of Integrated Salt Disposition Project (ISDP) Salt Batch (''Macrobatch'') 5 have been analyzed for {sup 238}Pu, {sup 90}Sr, {sup 137}Cs, and by Inductively Coupled Plasma Emission Spectroscopy (ICPES). The results indicate good decontamination performance within process design expectations. While the data set is sparse, the results of this set and the previous set of results for Macrobatch 4 samples indicate generally consistent operations. The DSSHT samples show continued presence of titanium, likely from leaching of the monosodium titanate in the Actinide Removal process (ARP).
