The LOFT Emergency Core Coolant Piping Thermal Analysis was checked to insure that the calculations made would conservatively satisfy the requirements in the LOFT technical specifications. Some of the boundary conditions used have not been shown to be conservative and require review and possible re-analysis. One of the thermal models used could not be clearly related to a specific part of the piping geometry and requires further explanation. The remainder of the models, the use of the SIMIR code and the other boundary conditions appear conservative and reflect normal thermal analysis methodology and practice. However, the use of constant, rather than temperature varying, thermal properties for some materials may introduce a slight error in these analyses.

A letter report issued by the Government Accountability Office with an abstract that begins "Sexual assault is a crime with negative implications to military readiness and esprit de corps. In response to a congressional request, GAO, in 2008, reviewed Department of Defense (DOD) and U.S. Coast Guard sexual assault prevention and response programs and recommended a number of improvements. GAO was subsequently asked to evaluate the extent to which (1) DOD has addressed GAO's 2008 recommendations and further developed its programs, (2) DOD has established a sexual assault database, and (3) the Coast Guard has addressed GAO's 2008 recommendations and further developed its programs. To do so, GAO analyzed legislative requirements and program guidance, interviewed officials, and compared database implementation efforts to key information technology best practices."

A letter report issued by the Government Accountability Office with an abstract that begins "In 1992, the United States began a unilateral moratorium on the testing of nuclear weapons. To compensate for the lack of testing, the Department of Energy's National Nuclear Security Administration (NNSA) developed the Stockpile Stewardship Program to assess and certify the safety and reliability of the nation's nuclear stockpile without nuclear testing. In 2001, NNSA's weapons laboratories began developing what is intended to be a common framework for a new methodology for assessing and certifying the safety and reliability of the nuclear stockpile without nuclear testing. GAO was asked to evaluate (1) the new methodology NNSA is developing and (2) NNSA's management of the implementation of this new methodology."

A letter report issued by the Government Accountability Office with an abstract that begins "Out-of-pocket costs for military families who use DOD-subsidized child care are largely driven by policies that vary by service. DOD establishes income-based fee ranges for on-installation child care, but each service sets its own fees and discounts within these parameters. As a result, in school year 2010 the per-child costs that families from the same income categories paid for on-installation care varied by service and installation. For example, the monthly per-child cost for a family with an income of $50,000 could have ranged from $335 to $518. Families’ costs for off-installation child care through private providers are also affected by policy differences among the services. All services offer subsidies for off-installation care that are intended to make families’ costs comparable to those for on-installation care. In an effort to offer benefits to more families, some services use a fixed cap to limit the subsidy amount. In school year 2010, the Air Force and Navy capped their subsidies at $200 per child per month, and families in these services had higher average monthly costs for off-installation care than Army and Marine Corps families, and also had higher …

A letter report issued by the General Accounting Office with an abstract that begins "The Consolidated Appropriations Resolution of 2003 Conference Report mandated that GAO review the Office of Compliance (OOC), an independent legislative branch agency created by the Congressional Accountability Act of 1995 (CAA). OOC, a 15-person office with about $2 million in expenditures during fiscal year 2003, administers and enforces various CAA provisions related to fair employment and occupational safety and health among certain legislative branch agencies. OOC's current Executive Director has been in place since April 2001 and its General Counsel joined the Office in June 2003. The mandate directed GAO to assess the OOC's overall effectiveness and efficiency and to make recommendations, as appropriate."

A letter report issued by the Government Accountability Office with an abstract that begins "The Federal Motor Carrier Safety Administration's (FMCSA) Compliance, Safety, Accountability (CSA) program has helped the agency contact or investigate more motor carrier companies that own commercial trucks and buses and has provided a range of safety benefits to safety officials, law enforcement, and the industry than the previous approach, SafeStat. Specifically, from fiscal year 2007 to fiscal year 2012, FMCSA more than doubled its number of annual interventions, largely by sending warning letters to riskier carriers."

A letter report issued by the Government Accountability Office with an abstract that begins "In 2004, the Department of Defense (DOD) announced sweeping changes to restructure U.S. military presence overseas and reduce military posture in Europe. In August, 2010, the Secretary of Defense called for a review of DOD operations and activities to identify opportunities to decrease costs in order to free funds to support other DOD priorities. The Senate Appropriations Subcommittee on Military Construction and Veterans' Affairs asked GAO to determine the extent to which the European Command (EUCOM) (1) estimates and reports the total cost of DOD's installations in Europe and (2) has defined methods for evaluating posture alternatives and including the views of interagency stakeholders in its posture planning process. To address these objectives, GAO assessed DOD plans and guidance, reviewed planning efforts in EUCOM, and collected obligations data from the military services for the military construction, family housing, and operation and maintenance appropriations."

A letter report issued by the Government Accountability Office with an abstract that begins "The Food and Drug Administration (FDA), which is responsible for ensuring the safety of most of the U.S. food supply, is not required to review substances, such as spices and preservatives, added to food that are generally recognized as safe (GRAS) for their intended use. Currently, companies may determine a substance is GRAS without FDA's approval or knowledge. However, a few substances previously considered GRAS have later been banned; and concerns have been raised about the safety of other GRAS substances, including those containing engineered nanomaterials, materials manufactured at a tiny scale to take advantage of novel properties. GAO was asked to review the extent to which (1) FDA's oversight of new GRAS determinations helps ensure the safety of these substances, (2) FDA ensures the continued safety of current GRAS substances, and (3) FDA's approach to regulating engineered nanomaterials in GRAS substances helps ensure the safety of the food supply. GAO reviewed FDA data on GRAS substances and interviewed a range of stakeholders, among other things."

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the Department of Agriculture's (USDA) efforts to modernize and reorganize its county-based agencies, focusing on: (1) identifying USDA's major reorganization and modernization initiatives for these agencies; (2) examining the progress USDA has made in completing these initiatives; and (3) identifying major issues impeding progress toward completing the initiatives."

The objective of this research program was to take a highly multidisciplinary approach to define the biogeochemical factors that control technetium (Tc) mobility in FRC sediments. The aim was to use batch and column studies to probe the biogeochemical conditions that control the mobility of Tc at the FRC. Background sediment samples from Area 2 (pH 6.5, low nitrate, low {sup 99}Tc) and Area 3 (pH 3.5, high nitrate, relatively high {sup 99}Tc) of the FRC were selected (http://www.esd.ornl.gov/nabirfrc). For the batch experiments, sediments were mixed with simulated groundwater, modeled on chemical constituents of FRC waters and supplemented with {sup 99}Tc(VII), both with and without added electron donor (acetate). The solubility of the Tc was monitored, alongside other biogeochemical markers (nitrate, nitrite, Fe(II), sulfate, acetate, pH, Eh) as the 'microcosms' aged. At key points, the microbial communities were also profiled using both cultivation-dependent and molecular techniques, and results correlated with the geochemical conditions in the sediments. The mineral phases present in the sediments were also characterized, and the solid phase associations of the Tc determined using sequential extraction and synchrotron techniques. In addition to the batch sediment experiments, where discrete microbial communities with the potential to reduce and precipitate {sup …

The purpose of this Workshop on ''Functional Requirements for the Modeling of Fate and Transport of Waterborne CBRN Materials'' was to solicit functional requirements for tools that help Incident Managers plan for and deal with the consequences of industrial or terrorist releases of materials into the nation's waterways and public water utilities. Twenty representatives attended and several made presentations. Several hours of discussions elicited a set of requirements. These requirements were summarized in a form for the attendees to vote on their highest priority requirements. These votes were used to determine the prioritized requirements that are reported in this paper and can be used to direct future developments.

Protein transport across hydrophobic membranes that partition cellular compartments is essential in all cells. The twin arginine translocation (Tat) pathway transports proteins across the prokaryotic cytoplasmic membranes. Distinct from the universally conserved Sec pathway, which secretes unfolded proteins, the Tat machinery is unique in that it secretes proteins in a folded conformation, making it an attractive pathway for the transport and secretion of heterologously expressed proteins that are Sec-incompatible. During the past 7 years, the DOE-supported project has focused on the characterization of the diversity of bacterial and archaeal Tat substrates as well as on the characterization of the Tat pathway of a model archaeon, Haloferax volcanii, a member of the haloarchaea. We have demonstrated that H. volcanii uses this pathway to transport most of its secretome.
