Influences on the Height of the Stable Boundary Layer as seen in Large-Eddy Simulations

Description: Numerical weather prediction (NWP) models and atmospheric dispersion models rely on parameterizations of planetary boundary layer height. In the case of a stable boundary layer, errors in boundary layer height estimation can result in gross errors in boundary-layer evolution and in prediction of turbulent mixing within the boundary layer. We use large-eddy simulations (LES) of moderately stable boundary layers to characterize the effects of various physical processes on stable boundary layers. … more

Field-Scale Migration of 99Tc and 129I at the Nevada Test Site

Description: The groundwater at the Nevada Test Site (NTS) contains many long-lived radionuclides, including {sup 99}Tc (technetium) and {sup 129}I (iodine), as a result of 828 underground nuclear weapons tests conducted between 1951 and 1992. We synthesized a body of data collected on the distribution of {sup 99}Tc and {sup 129}I in groundwater to assess their migration at NTS, at field scales over distances of hundreds of meters and for durations up to forty years and under hydrogeologic conditions very s… more

BuildingPI: A future tool for building life cycle analysis

Description: Traditionally building simulation models are used at the design phase of a building project. These models are used to optimize various design alternatives, reduce energy consumption and cost. Building performance assessment for the operational phase of a buildings life cycle is sporadic, typically working from historical metered data and focusing on bulk energy assessment. Building Management Systems (BMS) do not explicitly incorporate feedback to the design phase or account for any changes, wh… more

Disposition of Tank 48H Organics By Fluidized Bed Steam Reforming (FBSR) (U)

Description: An In Tank Processing (ITP) technology was developed at the Savannah River Site to remove Cs-137 from high-level waste supernates. During the ITP process monosodium titanate and sodium tetraphenylborate (NaTPB) were added to the salt supernate to adsorb Sr-90/Pu-238 and precipitate Cs-137 as CsTPB, respectively. This process was demonstrated at the SRS in 1983. The demonstration produced 53,000 gallons of 2.5 weight per cent Cs rich precipitate containing TPB, which was later washed and diluted… more

Polyimide and BeO mini port card performance comparison for CDF Run IIb

Description: The new silicon detector design for CDF relies on advanced packaging solutions in order to attain the strict small size and low mass requirements dictated by the experiment's physics program. The silicon strip detector at CDF is composed of overlaying silicon sensors in the form of a barrel around the colliding beam. The electronic instrumentation (sensors, readout and transceiver chips) is assembled into the staves of this barrel. In this paper we describe the development of the mini port card… more

LBNL report of the vetting review of the GRETINA project

Description: GRETINA is a gamma-ray detector array capable of reconstructing the energy and spatial positions of gamma-ray interactions within the germanium crystals. It will be used to study the structure and stability of nuclei under various conditions. The new capabilities provided by gamma-ray tracking will give large gains in sensitivity for a large number of experiments, particularly those aimed at nuclei far from beta stability. A proposal for GRETINA was submitted to DOE in June 2003. It presented t… more

Implementation of Methodology for Final Hazard Categorization of a DOE Nuclear Facility

Description: U.S. Department of Energy (DOE) nuclear facilities are categorized by the level of hazard they pose to workers, the general public, and the environment. This paper applies the methodology outlined in DOE-STD-1027-92 and interpreted in recent DOE guidance to a nuclear material storage facility at the Savannah River Site to reduce the category of the facility to below HC-3.

ADMP Mixing of Tank 18F: History, Modeling, Testing, and Results

Description: Residual radioactive waste was removed from Tank 18F in the F-Area Tank Farm at Savannah River Site (SRS), using the advanced design mixer pump (ADMP). Known as a slurry pump, the ADMP is a 55 foot long pump with an upper motor mounted to a steel super structure, which spans the top of the waste tank. The motor is connected by a long vertical drive shaft to a centrifugal pump, which is submerged in waste near the tank bottom. The pump mixes, or slurries, the waste within the tank so that it may… more

The taming of the Grid : virtual application services.

Description: In this report we develop a view of the Grid based on the application service provider (ASP) model. This view enables the user to see the Grid as a collection of application services that can be published, discovered, and accessed in a relatively straightforward manner, hiding much of the complexity involved in using computational Grids and thus making it simpler and more accessible to a wider range of users. However, in order to satisfy the requirements of real-time scientific application clie… more

Statistical Study of Weight % Insoluble Solids Methods for In-Tank Precipitation Cold Run Support

Description: A statistical study was performed on two candidate methods for measuring the weight percentage insoluble solids in ITP slurry samples. This work was necessary because the preferred method for using a microwave power weight percentage solids analyzer was unsuccessful. The weight percentage solids measurements are needed to provide process control information during the ITP cold runs.

Hexavalent uranium diffusion into soils from concentrated acidic and alkaline solutions

Description: Uranium contamination of soils and sediments often originates from acidic or alkaline waste sources, with diffusion being a major transport mechanism. Measurements of U(VI) diffusion from initially pH 2 and pH 11 solutions into a slightly alkaline Altamont soil and a neutral Oak Ridge soil were obtained through monitoring uptake from boundary reservoirs and from U concentration profiles within soil columns. The soils provided pH buffering, resulting in diffusion at nearly constant pH. Micro x-r… more

A finite difference model used to predict the consolidation of a ceramic waste form produced from the electrometallurgical treatment of spent nuclear fuel.

Description: Argonne National Laboratory (ANL) has developed a process to immobilize waste salt containing fission products, uranium, and transuranic elements as chlorides in a glass-bonded ceramic waste form. This salt was generated in the electrorefining operation used in the electrometallurgical treatment of spent Experimental Breeder Reactor-II (EBR-II) fuel. The ceramic waste process culminates with an elevated temperature operation. The processing conditions used by the furnace, for demonstration scal… more

Specification and implementation of IFC based performance metrics to support building life cycle assessment of hybrid energy systems

Description: Minimizing building life cycle energy consumption is becoming of paramount importance. Performance metrics tracking offers a clear and concise manner of relating design intent in a quantitative form. A methodology is discussed for storage and utilization of these performance metrics through an Industry Foundation Classes (IFC) instantiated Building Information Model (BIM). The paper focuses on storage of three sets of performance data from three distinct sources. An example of a performance met… more

Is the Short Distance Scale a Result of a Problem with the LMC Photometric Zero Point?

Description: I present a promising route to harmonize distance measurements based on clump giants and RR Lyrae stars. This is achieved by comparing the brightness of these distance indicators in three environments: the solar neighborhood, Galactic bulge and Large Magellanic Cloud (LMC). As a result of harmonizing the distance scales in the solar neighborhood and Baade's Window, I derive the new absolute magnitude of RR Lyrae stars, M{sub v}(RR) at [Fe/H] = -1.6 (0.59 {+-} 0.05, 0.70 {+-} 0.05).
