The Department of Energy selected CSSX as the preferred cesium removal technology for Savannah River Site waste. As a pretreatment step for the CSSX flowsheet, personnel contact the incoming salt solution that contains entrained sludge with MST to adsorb strontium and select actinides. They filter the resulting slurry to remove the sludge and MST. The filtrate receives further treatment to remove cesium in the solvent extraction system. The baseline filtration technology uses a Mott crossflow filter. We conducted pilot-scale crossflow filter testing with simulated SRS high level waste to evaluate the impact of operating parameters on the crossflow filtration process. The tests employed 0.5 micron and 0.1 micron filters. The feed slurries for these tests included simulated sludge plus MST, simulated sludge only, and simulated sludge plus manganese oxide solids. The supernate for these tests consisted of 5.6-6.4 M sodium, average salt solution. During the tests, we measured the axial pressure drop as a function of axial velocity, feed slurry, and insoluble solids concentration. This report documents the axial pressure drop data.

This project seeks to improve the basic understanding of the role of colloids in facilitating the transport of contaminants in the vadose zone. We focus on three major thrusts: (1) thermodynamic stability and mobility of colloids formed by reactions of sediments with highly alkaline tank waste solutions, (2) colloid-contaminant interactions, and (3) in situ colloid mobilization and colloid-facilitated contaminant transport occurring in both contaminated and uncontaminated Hanford sediments.

This report explains the various cotton subsidy programs and provides quantitative data on market revenues, production costs, and the size of the subsidies. Also, it characterizes the relative position of the United States vis-a-vis other countries as a producer, exporter and importer of cotton. The purpose of this examination is to provide U.S. policy makers with a complete overview of U.S. cotton production and the federal programs that support that production.

The Image Content Engine (ICE) project at Lawrence Livermore National Laboratory (LLNL) extracts, stores and allows queries of image content on multiple levels. ICE is designed for multiple application domains. The domain explored in this work is aerial and satellite surveillance imagery. The highest level of semantic information used in ICE is graph based. After objects are detected and classified, they are grouped based in their interrelations. The graph representing a locally related set of objects is called a 'graphlet'. Graphlets are interconnected into a larger graph which covers an entire set of images. Queries based on graph properties are notoriously difficult due the inherent complexity of the graph isomorphism and sub-graph isomorphism problems. ICE exploits limitations in graph and query structure and uses a set of auxiliary data structures to quickly process a useful set of graph based queries. These queries could not be processed using semantically lower level (tile and object based) queries.

Correspondence issued by the General Accounting Office with an abstract that begins "The U.S. space policy states that access to and use of space is critical to preserving peace and protecting U.S. national security and also benefits the country's civil and commercial interests. Air Force guidance explains further that access to space requires the ability to launch critical space assets, when needed, by a mix of space launch systems from standard launch pads at major support facilities. This is to ensure that a launch failure or other catastrophic event does not prevent mission success. These critical space assets, or satellites, are used for a wide range of government activities such as communications, navigation, and ballistic missile warning. The Evolved Expendable Launch Vehicle (EELV) program, consisting of both Atlas V and Delta IV launch vehicles, was established as the strategic launch system to meet the nation's critical space mission needs and correspond with U.S. policy that requires U.S. government satellites to be launched on U.S. manufactured launch vehicles. Specifically, the EELV program's overarching objective called for the development of a national expendable launch capability for assured access to space that would reduce the overall recurring cost of launch by at least …

The purpose of this revision of the System Design Description (SDD) is to establish requirements that drive the design of the electrical support system and their bases to allow the design effort to proceed to License Application. This SDD is a living document that will be revised at strategic points as the design matures over time. This SDD identifies the requirements and describes the system design as they exist at this time, with emphasis on those attributes of the design provided to meet the requirements. This SDD has been developed to be an engineering tool for design control. Accordingly, the primary audience/users are design engineers. This type of SDD both ''leads'' and ''trails'' the design process. It leads the design process with regard to the flow down of upper tier requirements onto the system. Knowledge of these requirements is essential in performing the design process. The SDD trails the design with regard to the description of the system. The description provided in the SDD is a reflection of the results of the design process to date. Functional and operational requirements applicable to electrical support systems are obtained from the ''Project Functional and Operational Requirements'' (F&OR) (Siddoway 2003). Other requirements to …

Conventional annular Hall thrusters become inefficient when scaled to low power. Cylindrical Hall thrusters, which have lower surface-to-volume ratio, are therefore more promising for scaling down. They presently exhibit performance comparable with conventional annular Hall thrusters. Electron cross-field transport in a 2.6 cm miniaturized cylindrical Hall thruster (100 W power level) has been studied through the analysis of experimental data and Monte Carlo simulations of electron dynamics in the thruster channel. The numerical model takes into account elastic and inelastic electron collisions with atoms, electron-wall collisions, including secondary electron emission, and Bohm diffusion. We show that in order to explain the observed discharge current, the electron anomalous collision frequency {nu}{sub B} has to be on the order of the Bohm value, {nu}{sub B} {approx} {omega}{sub c}/16. The contribution of electron-wall collisions to cross-field transport is found to be insignificant.

The plasma density peak observed at the axis of the 2.6 cm cylindrical Hall thruster is likely to be due to the convergent flux of ions, which are born in the annular part of the channel and accelerated towards the thruster axis.

The dynamic fracture of ductile metals is known to occur through the nucleation and growth of microscopic voids. As the voids grow, the surrounding metal is plastically deformed to accommodate the change in void volume. In order to gain better insight into void growth, gas gun recovery experiments were used to study incipient spallation fracture in light metals (Al, Cu, V). In addition to in-situ free surface velocity wave-profiles, the recovered samples were first analyzed using 3D X-ray tomography and then sectioned for 2D microscopy. The void size and spatial distribution were determined directly from the X-ray tomography. The single crystal samples show a bimodal distribution of small voids with large (50-100 micron) well separated voids. The plastically damaged region surrounding the large voids is quantified using optical and electron backscattering microscopy. Microhardness measurements indicate this region to be harder than the surrounding metal. Concurrently, a molecular dynamics model of void nucleation and growth at high strain-rate was developed. The model is consistent with experimental observations, e.g. voids nucleate at the weakest points in the metal such as inclusions and grain boundary junctions. The nature of void growth in a single crystal is sensitive to the crystal structure with initially …

A letter report issued by the General Accounting Office with an abstract that begins "Effective training of information technology (IT) staff, as called for in the E-Government (E-Gov) Act of 2002, is essential to developing and retaining a qualified workforce. In an earlier report (GAO-03-390), we identified 22 leading practices, grouped into 5 key training management processes, used by private-sector companies to implement effective IT training. These practices suggest approaches that government agencies could consider. To assess IT training in the federal government, including its use of leading practices, we were asked to determine, among other things, to what extent federal agencies use our leading practices, the major obstacles in providing effective IT training and how agencies address them, and the progress the Office of Personnel Management (OPM) is making in issuing policies and performing evaluations to encourage agencies to provide effective IT training."
