Recently a Resistive Magnetohydrodynamics (MHD) package has been added to the KULL code. In order to be compatible with the underlying hydrodynamics algorithm, a new sub-zonal magnetics discretization was developed that supports arbitrary polygonal and polyhedral zones. This flexibility comes at the cost of many more unknowns per zone - approximately ten times more for a hexahedral mesh. We can eliminate some (or all, depending on the dimensionality) of the extra unknowns from the global matrix during assembly by using a Schur complement approach. This trades expensive global work for cache-friendly local work, while still allowing solution for the full system. Significant improvements in the solution time are observed for several test problems.

Advances in laser glass compositions and manufacturing have enabled a new class of high-energy/high-power (HEHP), petawatt (PW) and high-average-power (HAP) laser systems that are being used for fusion energy ignition demonstration, fundamental physics research and materials processing, respectively. The requirements for these three laser systems are different necessitating different glasses or groups of glasses. The manufacturing technology is now mature for melting, annealing, fabricating and finishing of laser glasses for all three applications. The laser glass properties of major importance for HEHP, PW and HAP applications are briefly reviewed and the compositions and properties of the most widely used commercial laser glasses summarized. Proposed advances in these three laser systems will require new glasses and new melting methods which are briefly discussed. The challenges presented by these laser systems will likely dominate the field of laser glass development over the next several decades.

Objective The Majorana demonstrator will operate at liquid Nitrogen temperatures to ensure optimal spectrometric performance of its High Purity Germanium (HPGe) detector modules. In order to transfer the heat load of the detector module, the Majorana demonstrator requires a cooling system that will maintain a stable liquid nitrogen temperature. This cooling system is required to transport the heat from the detector chamber outside the shield. One approach is to use the two phase liquid-gas equilibrium to ensure constant temperature. This cooling technique is used in a thermosyphon. The thermosyphon can be designed so the vaporization/condensing process transfers heat through the shield while maintaining a stable operating temperature. A prototype of such system has been built at PNNL. This document presents the experimental results of the prototype and evaluates the heat transfer performance of the system. The cool down time, temperature gradient in the thermosyphon, and heat transfer analysis are studied in this document with different heat load applied to the prototype.

A series of experiments were conducted to determine the effect of pore size on pumping efficiency and zinc vapor trapping efficiency. A simple pumping efficiency test was conducted for all five pore diameters where it was observed that evacuation times were adversely affected by reducing the pore size below 5 {micro}m. Common test conditions for the zinc trapping efficiency experiments were used. These conditions resulted in some variability, to ascribe different efficiencies to the filter media. However, the data suggest that there is no significant difference in trapping efficiency for filter media with pores from 0.2 to 20 {micro}m with a thickness of 0.065-inch. Consequently, the 20 {micro}m pore filter media that is currently used at SRS is a suitable filter material for to utilize for future extractions. There is evidence that smaller pore filter will adversely affect the pumping times for the TEF and little evidence to suggest that a smaller pore diameters have significant impact on the trapping efficiency.

An experimental program was initiated in order to develop and validate conditions that will effectively trap Zn vapors that are released during extraction. The proposed work is broken down into three tasks. The first task is to determine the effectiveness of various pore sizes of filter elements. The second task is to determine the effect of filter temperature on zinc vapor deposition. The final task is to determine whether the zinc vapors can be chemically bound. The approach for chemically binding the zinc vapors has two subtasks, the first is a review of literature and thermodynamic calculations and the second is an experimental approach using the best candidates. This report details the results of the thermodynamic calculations to determine feasibility of chemically binding the zinc vapors within the furnace module, specifically the lithium trap (1). A review of phase diagrams, literature, and thermodynamic calculations was conducted to determine if there are suitable materials to capture zinc vapor within the lithium trap of the extraction basket. While numerous elements exist that form compounds with zinc, many of these also form compounds with hydrogen or the water that is present in the TPBARs. This relatively comprehensive review of available data indicates that …

Due to higher than expected permeation rates in the production of tritium in the TVA, a development and testing program was implemented to develop the understanding of why the higher rates were occurring. In addition, improved data are needed for both the design as well as the predictive models. One part of the program was to determine the equilibrium pressure of hydrogen and tritium over NPZ (1). During the course of this testing, some curious results were discovered (2) compared to the published literature data (3). Due to these apparently results, a follow-on task was undertaken to determine the equilibrium pressure of protium and deuterium over pure zirconium. A series of experiments were conducted to determine equilibrium pressures and isotherm data for the zirconium - protium and zirconium - deuterium systems. The data match the published literature data reasonably well with the plateau extending to loadings of about 1.4. There is a significant pressure rise for loadings greater than 1.7.

Twenty five glasses were formulated. They were batched from HLW AZ-101 simulant or raw chemicals and melted and tested with a series of tests to elucidate the effect of spinel-forming components (Ni, Fe, Cr, Mn, and Zn), Al, and noble metals (Rh2O3 and RuO2) on the accumulation rate of spinel crystals in the glass discharge riser of the high-level waste (HLW) melter. In addition, the processing properties of glasses, such as the viscosity and TL, were measured as a function of temperature and composition. Furthermore, the settling of spinel crystals in transparent low-viscosity fluids was studied at room temperature to access the shape factor and hindered settling coefficient of spinel crystals in the Stokes equation. The experimental results suggest that Ni is the most troublesome component of all the studied spinel-forming components producing settling layers of up to 10.5 mm in just 20 days in Ni-rich glasses if noble metals or a higher concentration of Fe was not introduced in the glass. The layer of this thickness can potentially plug the bottom of the riser, preventing glass from being discharged from the melter. The noble metals, Fe, and Al were the components that significantly slowed down or stopped the accumulation …

Over the last project six months, our project activities have concentrated on three areas: (1) performing a stochastic inversion of pattern 16 seismic data to deduce reservoir permeability, (2) development of the geochemical inversion strategy and implementation of associated software, and (3) completing the software implementation of TProGS and the geostatistical analysis that provides the information needed when using the software to produce realizations of the Midale reservoir. The report partially the following deliverables: D2: Model development: MCMC tool (synthetic fluid chemistry data); deliverable completed. D4: Model development/verification: MCMC tool (TProGS, field seismic/chemistry data) work product; deliverable requirements partially fulfilled. D5: Field-based single-pattern simulations work product; deliverable requirements partially fulfilled. When completed, our completed stochastic inversion tool will explicitly integrate reactive transport modeling, facies-based geostatistical methods, and a novel stochastic inversion technique to optimize agreement between observed and predicted storage performance. Such optimization will be accomplished through stepwise refinement of: (1) the reservoir model - principally its permeability magnitude and heterogeneity - and (2) geochemical parameters - primarily key mineral volume fractions and kinetic data. We anticipate that these refinements will facilitate significantly improved history matching and forward modeling of CO{sub 2} storage. Our tool uses the Markov Chain Monte …

Seal durability is critical to achieving the 2010 DOE operational life goals for both stationary and transportation PEM fuel cell stacks. The seal material must be chemically and mechanically stable in an environment consisting of aggressive operating temperatures, humidified gases, and acidic membranes. The seal must also be producible at low cost. Currentlyused seal materials do not meet all these requirements. This project developed and demonstrated a high consistency hydrocarbon rubber seal material that was able to meet the DOE technical and cost targets. Significant emphasis was placed on characterization of the material and full scale molding demonstrations.

This paper discusses the Savannah River Site Accelerated Transuranic (TRU) Waste Project that was initiated in April of 2009 to accelerate the disposition of remaining legacy transuranic waste at the site. An overview of the project execution strategy that was implemented is discussed along with the lessons learned, challenges and improvements to date associated with waste characterization, facility modifications, startup planning, and remediation activities. The legacy waste was generated from approximately 1970 through 1990 and originated both on site as well as at multiple US Department of Energy sites. Approximately two thirds of the waste was previously dispositioned from 2006 to 2008, with the remaining one third being the more hazardous waste due to its activity (curie content) and the plutonium isotope Pu-238 quantities in the waste. The project strategy is a phased approach beginning with the lower activity waste in existing facilities while upgrades are made to support remediation of the higher activity waste. Five waste remediation process lines will be used to support the full remediation efforts which involve receipt of the legacy waste container, removal of prohibited items, venting of containers, and resizing of contents to fit into current approved waste shipping containers. Modifications have been minimized …

A letter report issued by the Government Accountability Office with an abstract that begins "The challenges of securing the U.S.-Canadian border involve the coordination of multiple partners. The results of the Department of Homeland Security's (DHS) efforts to integrate border security among its components and across federal, state, local, tribal, and Canadian partners are unclear. GAO was asked to address the extent to which DHS has (1) improved coordination with state, local, tribal, and Canadian partners; (2) progressed in addressing past federal coordination challenges; and (3) progressed in securing the northern border and used coordination efforts to address existing vulnerabilities. GAO reviewed interagency agreements, strategies, and operational documents that address DHS's reported northern border vulnerabilities such as terrorism. GAO visited four Border Patrol sectors, selected based on threat, and interviewed officials from federal, state, local, tribal, and Canadian agencies operating within these sectors. While these results cannot be generalized, they provided insights on border security coordination."

A letter report issued by the Government Accountability Office with an abstract that begins "E-Verify is a system to electronically verify work eligibility and operated by the Department of Homeland Security's (DHS) U.S. Citizenship and Immigration Services (USCIS) and the Social Security Administration (SSA). GAO testified in June 2008 that ensuring accuracy and combating fraud were challenges facing E-Verify. As requested, GAO examined the extent to which USCIS and SSA took efforts to (1) reduce tentative nonconfirmations (TNC) and E-Verify's vulnerability to fraud, (2) safeguard employee personal information, and (3) prepare for possible mandatory use by all employers nationwide. GAO reviewed key policy and procedural documents, interviewed relevant DHS and SSA officials, and conducted site visits to three states selected, in part, based on employer types."

A letter report issued by the Government Accountability Office with an abstract that begins "Four federal agencies--the Forest Service in the Department of Agriculture and the Bureau of Land Management, Fish and Wildlife Service, and National Park Service in the Department of the Interior--are responsible for managing federal lands, enforcing federal laws governing the lands and their resources, and ensuring visitor safety. Illegal activities occurring on these lands have raised concerns that the four agencies are becoming less able to protect our natural and cultural resources and ensure public safety. GAO examined (1) the types of illegal activities occurring on federal lands and the effects of those activities on natural and cultural resources, the public, and agency employees; (2) how the agencies have used their law enforcement resources to respond to these illegal activities; and (3) how the agencies determine their law enforcement resource needs and distribute these resources. GAO reviewed agency documents, interviewed agency officials, and visited or contacted 26 selected agency units."

A letter report issued by the Government Accountability Office with an abstract that begins "Congress created the Neighborhood Stabilization Program (NSP) to help reduce the number of foreclosed and abandoned properties and restore depressed local housing markets. The Housing and Economic Recovery Act of 2008 (HERA) authorized the program's first round (NSP 1), providing $3.92 billion in grant funds to states and local governments. The Department of Housing and Urban Development (HUD) administers the program. HERA mandated that GAO report on whether grantees were using NSP 1 funds in accordance with the act's criteria. For this mandate, GAO examined (1) grantees' progress and challenges in meeting NSP 1 obligation and income-targeting requirements, (2) HUD's actions to mitigate program risks and ensure grantees' compliance with key NSP 1 requirements, and (3) HUD's efforts to collect program data and assess program performance. To address these objectives, GAO analyzed HUD data and the information system used for NSP 1; interviewed HUD officials and representatives of NSP 1 grantees; analyzed HUD's internal control processes; and conducted limited tests of 8 grantees' compliance with key NSP 1 requirements."

A letter report issued by the Government Accountability Office with an abstract that begins "A catastrophic public health event could threaten our national security and cause hundreds of thousands of casualties. Recognizing the need for efficient sharing of real-time information to help prevent devastating consequences of public health emergencies, Congress included in the Pandemic and All-Hazards Preparedness Act in December 2006 a mandate for the Secretary of the Department of Health and Human Services (HHS), in collaboration with state, local, and tribal public health officials, to develop and deliver to Congress a strategic plan for the establishment and evaluation of an electronic nationwide public health situational awareness capability. Pursuant to requirements of the act, GAO reviewed HHS's plans for and status of efforts to implement these capabilities, described collaborative efforts to establish a network, and determined grants authorized by the act and awarded to public health entities. GAO assessed relevant strategic planning documents and interviewed HHS officials and public health stakeholders."
