Anthrax: DHS Faces Challenges in Validating Methods for Sample Collection and Analysis
A letter report issued by the Government Accountability Office with an abstract that begins "A workgroupled by the U.S. Department of Homeland Security (DHS) and made up of DHS and the Centers for Disease Control and Prevention (CDC), the Environmental Protection Agency (EPA), the Federal Bureau of Investigation (FBI), and the National Institute of Standards and Technology (NIST)has attempted to address GAOs recommendations to (1) validate environmental sampling methods for detecting Bacillus anthracis and (2) conduct studies to develop probability-based sampling approaches for indoor environments. This workgroup has taken some actions to validate environmental sampling methods (collection, transportation, preparation, analysis) and develop statistically based sampling approaches that will provide confidence statements when test results are negative. These activities were projected to be completed by fiscal year 2013, but delays are now expected."

Coast Guard: Legacy Vessels' Declining Conditions Reinforce Need for More Realistic Operational Targets [Reissued on August 30, 2012]
A letter report issued by the Government Accountability Office with an abstract that begins "From fiscal years 2005 through 2011, the physical condition of the Coast Guard’s legacy vessels was generally poor; and the Coast Guard has taken two key actions to improve the vessels’ condition: reorganizing its maintenance command structure and implementing sustainment initiatives for portions of its legacy vessel fleet. The Coast Guard’s primary measure of a vessel’s condition is the operational percent of time free of major casualties (a major casualty is a deficiency in mission essential equipment that causes the major degradation or loss of a primary mission). This measure shows that the 378-foot high endurance cutters (HEC), the 210-foot and 270-foot medium endurance cutters (MEC), and 110-foot patrol boats generally remained well below target levels from fiscal years 2005 through 2011. To improve the condition of the vessel fleet, in 2009, the Coast Guard reorganized its maintenance command structure to focus on standardization of practices, and reported it was on schedule to complete sustainment initiatives by fiscal year 2014, which are intended to improve vessel operating and cost performance."

Development and validation of a radial inflow turbine model for simulation of the SNL S-CO2 split-flow loop.
A one-dimensional model for a radial inflow turbine has been developed for super-critical carbon dioxide (S-CO{sub 2}) Brayton cycle applications. The model accounts for the main phenomena present in the volute, nozzle, and impeller of a single-stage turbine. These phenomena include internal losses due to friction, blade loading, and angle of incidence and parasitic losses due to windage and blade-housing leakage. The model has been added as a component to the G-PASS plant systems code. The model was developed to support the analysis of S-CO{sub 2} cycles in conjunction with small-scale loop experiments. Such loops operate at less than a MWt thermal input. Their size permits components to be reconfigured in new arrangements relatively easily and economically. However, the small thermal input combined with the properties of carbon dioxide lead to turbomachines with impeller diameters of only one to two inches. At these sizes the dominant phenomena differ from those in larger more typical machines. There is almost no treatment in the literature of turbomachines at these sizes. The present work therefore is aimed at developing turbomachine models that support the task of S-CO{sub 2} cycle analysis using small-scale tests. Model predictions were compared against data from an experiment performed …

EFFECT OF CATIONS ON ALUMINUM SPECIATION UNDER ALKALINE CONDITIONS
A series of experiments were performed to examine the effect of metal cations common to high level waste on the phase of aluminum formed. Experiments were performed at temperature of 150 C, 75 C, and room temperature, either without additional metal cation, or with 0.01-0.2 molar equivalents of either Ni{sup 2+}, Fe{sup 3+}, Mn{sup 2+}, or Cr{sup 3+}. Results showed that temperature has the greatest effect on the phase obtained. At 150 C, boehmite is the only phase obtained, independent of the presence of other metal cations, with only one exception where a small amount of gibbsite was also detected in the product when 0.2 equivalents of Ni{sup 2+} was present. At 75 C, a mixture of phases is obtained, most commonly including bayerite and gibbsite; however, boehmite is also formed under some conditions, including in the absence of additional metal ion. At room temperature, in the absence of additional metal ion, a mixture of bayerite and gibbsite is obtained. The addition of another metal cation suppresses the formation of gibbsite, with a couple of exceptions (0.2 equivalents of Ni{sup 2+} or 0.01 equivalents of Cr{sup 3+}) where both phases are still obtained.

Energy Saving Melting and Revert Reduction Technology (E-SMARRT): Development of Surface Engineered Coating Systems for Aluminum Pressure Die Casting Dies: Towards a 'Smart' Die Coating
The main objective of this research program was to design and develop an optimal coating system that extends die life by minimizing premature die failure. In high-pressure aluminum die-casting, the die, core pins and inserts must withstand severe processing conditions. Many of the dies and tools in the industry are being coated to improve wear-resistance and decrease down-time for maintenance. However, thermal fatigue in metal itself can still be a major problem, especially since it often leads to catastrophic failure (i.e. die breakage) as opposed to a wear-based failure (parts begin to go out of tolerance). Tooling costs remain the largest portion of production costs for many of these parts, so the ability prevent catastrophic failures would be transformative for the manufacturing industry.The technology offers energy savings through reduced energy use in the die casting process from several factors, including increased life of the tools and dies, reuse of the dies and die components, reduction/elimination of lubricants, and reduced machine down time, and reduction of Al solder sticking on the die. The use of the optimized die coating system will also reduce environmental wastes and scrap parts. Current (2012) annual energy saving estimates, based on initial dissemination to the casting …

Energy Saving Melting and Revert Reduction Technology (E-SMARRT): Melting Efficiency Improvement
Steel foundries melt recycled scrap in electric furnaces and typically consume 35-100% excess energy from the theoretical energy requirement required to pour metal castings. This excess melting energy is multiplied by yield losses during casting and finishing operations resulting in the embodied energy in a cast product typically being three to six times the theoretical energy requirement. The purpose of this research project was to study steel foundry melting operations to understand energy use and requirements for casting operations, define variations in energy consumption, determine technologies and practices that are successful in reducing melting energy and develop new melting techniques and tools to improve the energy efficiency of melting in steel foundry operations.

EVALUATION OF ALTERNATIVE FILTER MEDIA FOR THE ROTARY MICROFILTER, PHASE 2
Testing was conducted at the Savannah River National Laboratory (SRNL) to investigate filter membrane performance in an effort to increase rotary microfilter (RMF) throughput. Membranes were tested in the SpinTek Filtration, Inc. Static Test Cell (STC), which permitted quick and easy testing of several different membranes. Testing consisted of 100 hours tests with two different slurry feeds, based on recommendations from the phase 1 testing. One feed contained Monosodium Titanate (MST) solids in a simulated salt solution. The other feed contained simulated sludge batch 6 (SB6) solids in a simulated salt solution. Five membranes were tested, one each from filter manufactures Pall and Porvair and three from the Oak Ridge National Laboratory (ORNL). The membrane from Pall is the current membrane used on the latest generation RMF. The Porvair membrane performed well in previous STC tests as well as one of the ORNL membranes. The other two membranes from ORNL were recently developed and not available for the previous STC test. The results indicate that the Porvair filter performed best with the MST slurry and the ORNL SVB6-1B filter performed best with the SB6 slurry. Difficulty was encountered with the ORNL filters due to their dimensional thickness, which was greater …

The Evolution of the Federal Monitoring and Assessment Center
The Federal Radiological Monitoring and Assessment Center (FRMAC) is a federal emergency response asset whose assistance may be requested by the Department of Homeland Security (DHS), the Department of Defense (DoD), the Environmental Protection Agency (EPA), the Nuclear Regulatory Commission (NRC), and state and local agencies to respond to a nuclear or radiological incident. It is an interagency organization with representation from the Department of Energy’s National Nuclear Security Administration (DOE/NNSA), the Department of Defense (DoD), the Environmental Protection Agency (EPA), the Department of Health and Human Services (HHS), the Federal Bureau of Investigation (FBI), and other federal agencies. FRMAC, in its present form, was created in 1987 when the radiological support mission was assigned to the DOE’s Nevada Operations Office by DOE Headquarters. The FRMAC asset, including its predecessor entities, was created, grew, and evolved to function as a response to radiological incidents. Radiological emergency response exercises showed the need for a coordinated approach to managing federal emergency monitoring and assessment activities. The mission of FRMAC is to coordinate and manage all federal radiological environmental monitoring and assessment activities during a nuclear or radiological incident within the United States in support of state,local, tribal governments, DHS, and the federal …

An Experimental and Theoretical High Energy Physics Program
The Purdue High Energy Physics Group conducts research in experimental and theoretical elementary particle physics and experimental high energy astrophysics. Our goals, which we share with high energy physics colleagues around the world, are to understand at the most fundamental level the nature of matter, energy, space and time, and in order to explain the birth, evolution and fate of the Universe. The experiments in which we are currently involved are: CDF, CLEO-c, CMS, LSST, and VERITAS. We have been instrumental in establishing two major in-house facilities: The Purdue Particle Physics Microstructure Detector Facility (P3MD) in 1995 and the CMS Tier-2 center in 2005. The research efforts of the theory group span phenomenological and theoretical aspects of the Standard Model as well as many of its possible extensions. Recent work includes phenomenological consequences of supersymmetric models, string theory and applications of gauge/gravity duality, the cosmological implications of massive gravitons, and the physics of extra dimensions.

Fabrication of Pd/Pd-Alloy Films by Surfactant Induced Electroless Plating for Hydrogen Separation from Advanced Coal Gasification Processes
Dense Pd, Pd-Cu and Pd-Ag composite membranes on microporous stainless steel substrate (MPSS) were fabricated by a novel electroless plating (EP) process. In the conventional Pd-EP process, the oxidation-reduction reactions between Pd-complex and hydrazine result in an evolution of NH{sub 3} and N{sub 2} gas bubbles. When adhered to the substrate surface and in the pores, these gas bubbles hinder uniform Pd-film deposition which results in dendrite growth leading to poor film formation. This problem was addressed by introducing cationic surfactant in the electroless plating process known as surfactant induced electroless plating (SIEP). The unique features of this innovation provide control of Pd-deposition rate, and Pd-grain size distribution. The surfactant molecules play an important role in the EP process by tailoring grain size and the process of agglomeration by removing tiny gas bubbles through adsorption at the gas-liquid interface. As a result surfactant can tailor a nanocrystalline Pd, Cu and Ag deposition in the film resulting in reduced membrane film thickness. Also, it produces a uniform, agglomerated film structure. The Pd-Cu and Pd-Ag membranes on MPSS support were fabricated by sequential deposition using SIEP method. The pre- and post-annealing characterizations of these membranes (Pd, Pd-Cu and Pd-Ag on MPSS substrate) …
