This report documents the progress made through FY 2010 on a project initiated in FY 2006 to help address uncertainties related to the rates of hydrolysis in groundwater at the Hanford Site for carbon tetrachloride (CT) and chloroform (CF). The study also explores the possible effects of contact with minerals and sediment (i.e., heterogeneous hydrolysis) on these rates. The research was initiated to decrease the uncertainties in abiotic degradation rates of CT and chloroform CF associated with temperature and possible heterogeneous effects. After 2 years of data collection, the first evidence for heterogeneous effects was identified for hydrolysis of CT, and preliminary evidence for the effects of different mineral types on CF hydrolysis rates also was reported. The CT data showed no difference among mineral types, whereas significant differences were seen in the CF results, perhaps due to the fact that CF hydrolyzes by both neutral and base-catalyzed mechanisms whereas CT follows only the neutral hydrolysis path. In this report, we review the project objectives, organization, and technical approaches taken, update the status and results of the hydrolysis-rate experiments after 4 years of experimentation (i.e., through FY 2010), and provide a brief discussion of how these results add to scientific …

The destabilized complex hydride system composed of LiNH{sub 2}:MgH{sub 2} (1:1 molar ratio) is one of the leading candidates of hydrogen storage with a reversible hydrogen storage capacity of 8.1 wt%. A low sorption enthalpy of {approx}32 kJ/mole H{sub 2} was first predicted by Alapati et al. utilizing first principle density function theory (DFT) calculations and has been subsequently confirmed empirically by Lu et al. through differential thermal analysis (DTA). This enthalpy suggests that favorable sorption kinetics should be obtainable at temperatures in the range of 160 C to 200 C. Preliminary experiments reported in the literature indicate that sorption kinetics are substantially lower than expected in this temperature range despite favorable thermodynamics. Systematic isothermal and isobaric sorption experiments were performed using a Sievert's apparatus to form a baseline data set by which to compare kinetic results over the pressure and temperature range anticipated for use of this material as a hydrogen storage media. Various material preparation methods and compositional modifications were performed in attempts to increase the kinetics while lowering the sorption temperatures. This paper outlines the results of these systematic tests and describes a number of beneficial additions which influence kinetics as well as NH{sub 3} formation.

Vacuum and extreme ultraviolet radiation from 8 - 24 eV generated at a synchrotron was used to postionize laser desorbed neutrals of antibiotic-treated biofilms and a modified fullerene using laser desorption postionization mass spectrometry (LDPI-MS). Results show detection of the parent ion, various fragments, and extracellular material from biofilms using LDPI-MS with both vacuum and extreme ultraviolet photons. Parent ions were observed for both cases, but extreme ultraviolet photons (16-24 eV) induced more fragmentation than vacuum ultraviolet (8-14 eV) photons.

A letter report issued by the Government Accountability Office with an abstract that begins "Corrosion costs DOD over $23 billion annually, affects both equipment and facilities, and threatens personnel safety. DOD has taken steps to improve its corrosion prevention and control (CPC) efforts. These efforts include reorganizing the DOD-wide Corrosion Office and instituting Corrosion Executive positions in each of the military departments. In response to the Senate Appropriations Committee Report accompanying the fiscal year 2010 DOD appropriations bill, GAO evaluated to what extent (1) the Corrosion Executives are involved in preparing CPC project proposals for submission, (2) the Corrosion Office has created a process to review and select projects for funding, and (3) the military departments have validated the return on investment (ROI) for funded projects. GAO also reviewed the process the Corrosion Office uses to determine the CPC activities that it will fund. To carry out this study, GAO observed project selection panel meetings, interviewed corrosion officials, and reviewed documents and project proposals."

Correspondence issued by the Government Accountability Office with an abstract that begins "The National Military Strategy of the United States calls upon the Armed Forces to retain the ability to rapidly deploy and sustain capabilities to diverse regions, and the Quadrennial Defense Review 2010 acknowledges the fundamental importance of U.S. capability to project power. The National Security Strategy identifies taking stock of capabilities as one of many ways of reducing military risk. To identify the mobility tools needed for force projection, the Department of Defense (DOD) has conducted several studies, including the fifth and most recent--the Mobility Capabilities and Requirements Study 2016 (MCRS-16). DOD issued the report in February 2010. The intent of the MCRS-16 was to provide senior leaders with a detailed understanding of the range of mobility capabilities needed for possible future strategic environments and help them make investment decisions regarding mobility systems. Specifically, the study was to examine, among other things, how changes in the mobility system affect the outcomes of major operations and to assess the associated risks. The MCRS-16 determined that with few exceptions, the projected mobility capabilities in 2016 are sufficient to support the most demanding projected requirements. The MCRS-16 reported on specific mobility …

Savannah River Remediation (SRR) LLC assumed the liquid waste contract at the Savannah River Site (SRS) in the summer of 2009. The main contractual agreement was to close 22 High Level Waste (HLW) tanks in eight years. To achieve this aggressive commitment, faster waste processing throughout the SRS liquid waste facilities will be required. Part of the approach to achieve faster waste processing is to increase the canister production rate of the Defense Waste Processing Facility (DWPF) from approximately 200 canisters filled with radioactive waste glass per year to 400 canisters per year. To reach this rate for melter throughput, four bubblers were installed in the DWPF Melter in the late summer of 2010. This effort required collaboration between SRR, SRR critical subcontractor EnergySolutions, and Savannah River Nuclear Solutions, including the Savannah River National Laboratory (SRNL). The tasks included design and fabrication of the bubblers and related equipment, testing of the bubblers for various technical issues, the actual installation of the bubblers and related equipment, and the initial successful operation of the bubblers in the DWPF Melter.

A letter report issued by the Government Accountability Office with an abstract that begins "Prior GAO testimonies have described cases of physical abuse of children at youth residential treatment programs and public and private schools. However, children are also vulnerable to sexual abuse. A 2004 Department of Education report estimated that millions of students are subjected to sexual misconduct by a school employee at some time between kindergarten and the twelfth grade (K-12). GAO was asked to (1) examine the circumstances surrounding cases where K-12 schools hired or retained individuals with histories of sexual misconduct and determine the factors contributing to such employment actions and (2) provide an overview of selected federal and state laws related to the employment of convicted sex offenders in K-12 schools. To identify case studies, GAO compared 2007 to 2009 data employment databases from 19 states and the District of Columbia to data in the National Sex Offender Registry. GAO also searched public records from 2000 to 2010 to identify cases in which sexual misconduct by school employees ultimately resulted in a criminal conviction. GAO ultimately selected 15 cases from 11 states for further investigation. For each case, to the extent possible, GAO reviewed court …

The objective of the Midwest Nuclear Science and Engineering Consortium (MNSEC) is to enhance the scope, quality and integration of educational and research capabilities of nuclear sciences and engineering (NS/E) programs at partner schools in support of the U.S. nuclear industry (including DOE laboratories). With INIE support, MNSEC had a productive seven years and made impressive progress in achieving these goals. Since the past three years have been no-cost-extension periods, limited -- but notable -- progress has been made in FY10. Existing programs continue to be strengthened and broadened at Consortium partner institutions. The enthusiasm generated by the academic, state, federal, and industrial communities for the MNSEC activities is reflected in the significant leveraging that has occurred for our programs.

Correspondence issued by the Government Accountability Office with an abstract that begins "The Navy's Littoral Combat Ship (LCS) is envisioned as a vessel able to be reconfigured to meet three different mission areas: mine countermeasures, surface warfare, and antisubmarine warfare. Its design concept consists of two distinct parts--the ship itself (seaframe) and the mission package it carries and deploys. The Navy is procuring the first four ships in two different designs from shipbuilding teams led by Lockheed Martin and General Dynamics, which currently build their designs at Marinette Marine and Austal USA shipyards, respectively. Prior to September 2009, the Navy planned to continue building the class using both ship designs. This strategy changed following unsuccessful contract negotiations that same year for fiscal year 2010 funded seaframes--an outcome attributable to industry proposals priced significantly above Navy expectations. In September 2009, the Navy announced that in an effort to improve affordability, it was revising the LCS program's acquisition strategy and would select one seaframe design before awarding contracts for any additional ships. Following approval of this strategy in January 2010, the Navy issued a new solicitation--intended to lead to a downselect--for fiscal year 2010 seaframes. In support of this strategy, Congress authorized …

The automatic alignment system for the National Ignition Facility (NIF) is a large-scale parallel system that directs all 192 laser beams along the 300-m optical path to a 50-micron focus at target chamber in less than 50 minutes. The system automatically commands 9,000 stepping motors to adjust mirrors and other optics based upon images acquired from high-resolution digital cameras viewing beams at various locations. Forty-five control loops per beamline request image processing services running on a LINUX cluster to analyze these images of the beams and references, and automaticallys teer the beams toward the target. This paper discusses the upgrades to the NIF automatic alignment system to handle new alignment needs and evolving requirements as related to various types of experiments performed. As NIF becomes a continuously-operated system and more experiments are performed, performance monitoring is increasingly important for maintenance and commissioning work. Data, collected during operations, is analyzed for tuning of the laser and targeting maintenance work. handling evolving alignment and maintenance needs is expected for the planned 30-year operational life of NIF.

Evaluation of life-cycle (or well-to-wheels, WTW) energy and emission impacts of vehicle/fuel systems requires energy use (or energy efficiencies) of energy processing or conversion activities. In most such studies, petroleum fuels are included. Thus, determination of energy efficiencies of petroleum refineries becomes a necessary step for life-cycle analyses of vehicle/fuel systems. Petroleum refinery energy efficiencies can then be used to determine the total amount of process energy use for refinery operation. Furthermore, since refineries produce multiple products, allocation of energy use and emissions associated with petroleum refineries to various petroleum products is needed for WTW analysis of individual fuels such as gasoline and diesel. In particular, GREET, the life-cycle model developed at Argonne National Laboratory with DOE sponsorship, compares energy use and emissions of various transportation fuels including gasoline and diesel. Energy use in petroleum refineries is key components of well-to-pump (WTP) energy use and emissions of gasoline and diesel. In GREET, petroleum refinery overall energy efficiencies are used to determine petroleum product specific energy efficiencies. Argonne has developed petroleum refining efficiencies from LP simulations of petroleum refineries and EIA survey data of petroleum refineries up to 2006 (see Wang, 2008). This memo documents Argonne's most recent update of petroleum …

This report provides an overview of current U.S. financial regulation: which agencies are responsible for which institutions, activities, and markets, and what kinds of authority they have. Some agencies regulate particular types of institutions for risky behavior or conflicts of interest, some agencies promulgate rules for certain financial transactions no matter what kind of institution engages in it, and other agencies enforce existing rules for some institutions, but not for others. These regulatory activities are not necessarily mutually exclusive.
