FINAL CLOSURE PLAN SURFACE IMPOUNDMENTS CLOSURE, SITE 300

Description: Lawrence Livermore National Laboratory of the University of California (LLNL) operates two Class II surface impoundments that store wastewater that is discharged from a number of buildings located on the Site 300 Facility (Site 300). The wastewater is the by-product of explosives processing. Reduction in the volume of water discharged from these buildings over the past several years has significantly reduced the wastewater storage needs. In addition, the impoundments were constructed in 1984, a… more

Recent Site-Wide Transport Modeling Related to the Carbon Tetrachloride Plume at the Hanford Site

Description: Carbon tetrachloride transport in the unconfined aquifer system at the Hanford Site has been the subject of follow-on studies since the Carbon Tetrachloride Innovative Treatment Remediation Demonstration (ITRD) Program was completed in FY 2002. These scoping analyses were undertaken to provide support for strategic planning and guidance for the more robust modeling needed to obtain a final record of decision (ROD) for the carbon tetrachloride plume in the 200 West Area. This report documents th… more

Solid State NMR Measurements for Preliminary Lifetime Assessments in gamma-Irradiated and Thermally Aged Siloxane Elastomers

Description: Siloxanes have a wide variety of applications throughout the aerospace industry which take advantage of their exceptional insulating and adhesive properties and general resilience. They also offer a wide range of tailorable engineering properties with changes in composition and filler content. They are, however, subject to degradation in radiatively and thermally harsh environments. We are using solid state nuclear magnetic resonance techniques to investigate changes in network and interfacial … more

Metals Verification Study for Sinclair and Dyes Inlets,Washington

Description: Sinclair and Dyes Inlets near Bremerton, Washington, are on the State of Washington's 1998 303(d) list of impaired waters because of fecal coliform contamination in marine water, metals in sediment and fish tissue, and organics in sediment and fish tissue. This Metals Verification Study was conducted to address the 303(d) segments that are listed for metal contaminants in marine sediment, because significant cleanup and source control activities have been conducted in the Inlets since the data … more

Measurements of Horizontal Flow in the Vicinity of a Building: A Field Study from June to December 1999

Description: The pattern of flow around a discrete, yet architecturally complex building is measured through the use of arrays of 2-D sonic anemometers. When the measurements are grouped according to upwind wind direction and normalized by the upwind wind speed, the resulting average vectors reveal persistent patterns of divergence, separation zones, and lee eddies. Additional measurements were made investigating specific details of flow. A pair of 10-m towers supported four levels of anemometers to explore… more

Progress Report FY04 Quarter 1

Description: In this quarter, a simulation has been carried out to validate the FEM model for a production facility mill configuration, focusing on the shape change evolution of the slab. Results of ingot shape evolution for a 13 pass rolling simulation are given in Figure 1. It was observed that the rollover of the slab is strongly dependent on friction. More studies on friction laws may be necessary for more accurate prediction. Another important feature is the mesh dependence of the result. More frequent… more

CT Scans of NASA BSTRA Balls 5f5, f2, f3, sr2c, nb2a, hb2b

Description: At the request of Jose Hernandez we performed some feasibility DR/CT scanning of BSTRA Balls of different sizes. To this point we have scanned all the specimens on a single system, HECAT. This particular system employs a 9 meV LINAC as the x-ray source and a THALES 12 x 16 inch 14-bit Amorphous Silicon panel as the detector. In this report we describe the system, detail some of its properties, describe the scans performed and present the data. Figure 1 contains a couple of images of the system … more

Electron-Cloud Effects on Heavy-Ion Beams

Description: Stray electrons can be introduced in positive-charge accelerators for heavy ion fusion (or other applications) as a result of ionization of ambient gas or gas released from walls due to halo-ion impact, or as a result of secondary-electron emission. We are developing a capability for self-consistent simulation of ion beams with the electron clouds they produce. We report on an ingredient in this capability, the effect of specified electron cloud distributions on the dynamics of a coasting ion b… more

Dynamic Bayesian Models via Monte Carlo - An Introduction with Examples -

Description: This report gives an introduction to a Bayesian probabilistic approach to modeling a dynamic system, with emphasis on stochastic methods for posterior inference. The Bayesian paradigm is a powerful tool to combine observed data along with prior knowledge to gain a current (probabilistic) understanding of unknown model parameters. In particular, it provides a very natural framework for updating the state of knowledge in a dynamic system. For complex systems, such updating needs to be carried out… more

Heat Pump Water Heater Durabliltiy Testing - Phase II

Description: Ten heat pump water heaters (HPWH) were placed in an environmentally controlled test facility and run through a durability test program of approximately 7300 duty cycles (actual cycles accumulated ranged from 6640 to 8324 for the ten units). Five of the units were upgraded integral types (HPWH mounted on storage tank, no pump) from the same manufacturer as those tested in our first durability program in 2001 (Baxter and Linkous, 2002). The other five were ''add-on'' type units (HPWH with circul… more
