Assessment of the Electrical Power Requirements for Continued Safe Storage and Waste Feed Delivery Phase 1 (open access)

Assessment of the Electrical Power Requirements for Continued Safe Storage and Waste Feed Delivery Phase 1

This study evaluated the ability of the electrical distribution system to support safe storage as well as the first phase of the Waste Feed Delivery. Several recommendations are made to improve the electrical system. The ability to assure adequate Waste Feed Delivery (WFD) to the Privatization Contractor's vitrification facility is a key element in the overall Hanford cleanup schedule. An important aspect of this WFD is the availability of sufficient and appropriate electrical power in the single- and double-shell tank farms. The methodology for performing this review and the results are described.

Focusing and Acceleration of Bunched Beams (open access)

Focusing and Acceleration of Bunched Beams

A new approach to solving the kinetic equation for the beam distribution function, (very useful from the practical point of view), is discussed, in which the authors also obtain a complement to the Skrinsky's condition for the self-focused bunched beam. This problem belongs to the theory of nonlinear systems in which both regular and chaotic motion is possible. The kinetic approach, based on Vlasov-Poisson equations, are used to investigate the focusing and acceleration of bunched beam. Special attention is given to the studies of stability in a bunched beam by means of the two norm, which may be used to describe t!he motion of high-energy particles.

Ground Control for Emplacement Drifts for SR (open access)

Ground Control for Emplacement Drifts for SR

This analysis demonstrates that a satisfactory ground control system can be designed for the Yucca Mountain site, and provides the technical basis for the design of ground support systems to be used in repository emplacement and non-emplacement drifts. The repository ground support design was based on analytical methods using acquired computer codes, and focused on the final support systems. A literature review of case histories, including the lessons learned from the design and construction of the ESF, the studies on the seismic damages of underground openings, and the use of rock mass classification systems in the ground support design, was conducted (Sections 6.3.4 and 6.4). This review provided some basis for determining the inputs and methodologies used in this analysis. Stability of the supported and unsupported emplacement and non-emplacement drifts was evaluated in this analysis. The excavation effects (i.e., state of the stress change due to excavation), thermal effects (i.e., due to heat output from waste packages), and seismic effects (i.e., from potential earthquake events) were evaluated, and stress controlled modes of failure were examined for two in situ stress conditions (k_0=0.3 and 1.0) using rock properties representing rock mass categories of 1 and 5. Variation of rock mass units …

Hindered Diffusion of Asphaltenes at Elevated Temperature and Pressure Progress Report (open access)

Hindered Diffusion of Asphaltenes at Elevated Temperature and Pressure Progress Report

During this past six months we continued our ongoing studies of the diffusion controlled uptake of coal and petroleum asphaltenes into a porous carbon catalyst. Toluene was used as the solvent for experiments at 20 C and 75 C while 1-methylnaphthalene was the solvent for the higher temperature experiments at 100 C, 150 C and 250 C. All runs were made at a pressure of 250 psi (inert He gas). Experiments were performed at 20 C and 75 C, for the petroleum asphaltene/toluene system. For the coal asphaltene/toluene system, experiments were performed at 75 C. Experiments were performed at 100 C, 150 C and 250 C for the coal asphaltene/1-methylnaphthalene system. A comparison between the experimental data and model simulated data showed that the mathematical model satisfactorily fitted the adsorptive diffusion of both the coal and petroleum asphaltenes onto a porous activated carbon. The adsorption constant decreases with an increase in temperature for both, the coal asphaltene/1-methylnaphthalene system as well as the petroleum asphaltene/toluene system. It was found that the adsorption constant for the coal asphaltene/toluene system at 75 C was much higher than that of the petroleum asphaltene/toluene system at the same temperature providing evidence of the greater affinity …

LOW-TEMPERATURE, ANODE-SUPPORTED HIGH POWER DENSITY SOLID OXIDE FUEL CELLS WITH NANOSTRUCTURED ELECTRODES

This report contains the following three parts. (1) An investigation into the use of direct liquid hydrocarbon fuels in single cell tests. (2) An analysis of residual stresses in anode-supported solid oxide fuel cells. (3) A manuscript on the synthesis of nanosize ceramic (electrode and electrolyte) powders. Nanosize YSZ powder was prepared by a unique approach, in which yttria-doped BaZrO{sub 3} or yttria-doped Na{sub 2}ZrO{sub 3} precursors were first synthesized by a solid state reaction. Then, then the unwanted species, BaO or Na{sub 2}O, was leached away by washing the precursors in a dilute HNO{sub 3} solution or in water. This led to the formation of very fine, nanosize yttria-stabilized zirconia (YSZ). The particle size of the as-synthesized YSZ powders was a few nanometers and increased to tens of nanometers after thermal treatment at a temperature as high as 1000 C. The as-synthesized as well as heat-treated YSZ powder was of cubic crystal structure.

LOW-TEMPERATURE, ANODE-SUPPORTED HIGH POWER DENSITY SOLID OXIDE FUEL CELLS WITH NANOSTRUCTURED ELECTRODES

Nanosize yttria-stabilized zirconia (YSZ) was synthesized by a unique approach based on molecular decomposition. In this approach, yttria-doped BaZrO{sub 3} (Y-BaZrO{sub 3}) or yttria-doped Na{sub 2}ZrO{sub 3} (Y-Na{sub 2}ZrO{sub 3}) precursors were first synthesized from BaCO{sub 3}, ZrO{sub 2}, Y2O{sub 3} or BaCO{sub 3} and commercial YSZ for Y-BaZrO{sub 3}, and from Na{sub 2}CO{sub 3} and YSZ for Y-Na{sub 2}ZrO{sub 3}, by a conventional solid state reaction method. Then, the precursors were boiled to leach away the unwanted species, BaO or Na{sub 2}O, either in a dilute HNO{sub 3} solution in water in the case of Y-BaZrO{sub 3}, or in de-ionized water in the case of Y-Na{sub 2}ZrO{sub 3}. During boiling in HNO{sub 3} or water, the insoluble residue of Zr-Y-O composition formed fine, nanosize YSZ particles. X-ray diffraction (XRD) and specific surface area measurements on the as-synthesized powders confirmed the formation of nanosize YSZ. A subsequent heating in air led to particle growth. However, for a treatment at a temperature as high as 1000 C, the particle size was well in the nanosize range. XRD showed that the as-synthesized YSZ powders, as well as those heated up to 1000 C, the maximum temperature the powders were heated to after …

Particle Tracking Model and Abstraction of Transport Processes (open access)

Particle Tracking Model and Abstraction of Transport Processes

The purpose of the transport methodology and component analysis is to provide the numerical methods for simulating radionuclide transport and model setup for transport in the unsaturated zone (UZ) site-scale model. The particle-tracking method of simulating radionuclide transport is incorporated into the FEHM computer code and the resulting changes in the FEHM code are to be submitted to the software configuration management system. This Analysis and Model Report (AMR) outlines the assumptions, design, and testing of a model for calculating radionuclide transport in the unsaturated zone at Yucca Mountain. In addition, methods for determining colloid-facilitated transport parameters are outlined for use in the Total System Performance Assessment (TSPA) analyses. Concurrently, process-level flow model calculations are being carrier out in a PMR for the unsaturated zone. The computer code TOUGH2 is being used to generate three-dimensional, dual-permeability flow fields, that are supplied to the Performance Assessment group for subsequent transport simulations. These flow fields are converted to input files compatible with the FEHM code, which for this application simulates radionuclide transport using the particle-tracking algorithm outlined in this AMR. Therefore, this AMR establishes the numerical method and demonstrates the use of the model, but the specific breakthrough curves presented do not …
