Ventilation Model

Description: The purpose of this analysis and model report (AMR) for the Ventilation Model is to analyze the effects of pre-closure continuous ventilation in the Engineered Barrier System (EBS) emplacement drifts and provide heat removal data to support EBS design. It will also provide input data (initial conditions, and time varying boundary conditions) for the EBS post-closure performance assessment and the EBS Water Distribution and Removal Process Model. The objective of the analysis is to develop, desc… more

Uranium (VI) and Neptunium (V) Transport Fractured, Hydrothermally Altered Concrete

Description: In a high level waste repository in which temperatures are elevated due to waste decay, concrete structures will be subjected to hydrothermal conditions that will alter their physical and chemical properties. Virtually no studies have examined the interaction of hydrothermally altered concrete with radionuclides. We present the results of experiments in which soluble and colloid-associated actinides, uranium (U) and neptunium (Np), were eluted into a fractured, hydrothermally altered concrete c… more

105-K Basin Material Design Basis Feed Description for Spent Nuclear Fuel (SNF) Project Facilities VOL 1 Fuel

Description: Metallic uranium Spent Nuclear Fuel (SNF) is currently stored within two water filled pools, 105-KE Basin (KE Basin) and 105-KW Basin (KW Basin), at the United States Department of Energy (U.S. DOE) Hanford Site, in southeastern Washington State. The Spent Nuclear Fuel Project (SNF Project) is responsible to DOE for operation of these fuel storage pools and for the 2100 metric tons of SNF materials that they contain. The SNF Project mission includes safe removal and transportation of all SNF fr… more

Improved Performance of the Alkaline-Side CSEX Process for Cesium Extraction from Alkaline High-Level Waste Obtained by Characterization of the Effect of Surfactant Impurities

Description: Improved understanding and performance of the alkaline-side CSEX process has been obtained through the characterization of impurity effects that hinder complete stripping of cesium from the solvent. It is shown in this report that tests of the alkaline-side CSEX process conducted in the summer and fall of 1998 were complicated by the presence of common surfactant anions, undecyl- and dodecylsulfonate, as trace impurities in the two simulants tested. This conclusion was drawn from the results of… more

Laser Plasma Coupling for High Temperature Hohlraums

Description: Simple scaling models indicate that quite high radiation temperatures can be achieved in hohlraums driven with the National Ignition Facility. A scaling estimate for the radiation temperature versus pulse duration for different size NIF hohlraums is shown in Figure 1. Note that a radiation temperature of about 650 ev is projected for a so-called scale 1 hohlraum (length 2.6mm, diameter 1.6mm). With such high temperature hohlraums, for example, opacity experiments could be carried out using more… more

Nonlinear Waves in Reaction Diffusion Systems: The Effect of Transport Memory

Description: Motivated by the problem of determining stress distributions in granular materials, we study the effect of finite transport correlation times on the propagation of nonlinear wavefronts in reaction diffusion systems. We obtain new results such as the possibility of spatial oscillations in the wavefront shape for certain values of the system parameters and high enough wavefront speeds. We also generalize earlier known results concerning the minimum wavefront speed and shape-speed relationships st… more

Impurities and defects in photovoltaic Si devices: A review

Description: The performance of commercial photovoltaic Si devices is strongly controlled by the impurities and defects present in the substrates. A well-designed solar cell processing sequence can mitigate their effects to yield high efficiency devices. Such a process-design requires a comprehensive knowledge of the properties of defects, impurities, and impurity-defect interactions that can occur during device processing. This paper reviews the recent understanding of the impurity and defect issues in Si-… more

Optical modeling of a-Si solar cells

Description: The authors describe applications of PV Optics to analyze the behavior of a metallic back-reflector on an a-Si solar cell. The calculated results from PV Optics agree well with the measured data on solar cells. Several unexpected results obtained from these calculations are qualitatively explained.

Use of Morphological Operators and Pattern Recognition Techniques for Sorting the First Data

Description: The application of morphological and pattern recognition techniques to the sorting of FIRST data is presented. FIRST (Faint Images of the Radio Sky at Twenty Centimeters) is designed to produce the radio equivalent of the Palomar Observatory Sky Survey, using the National Radio Astronomical Observatory Very Large Array. A catalog of source positions and Gaussian-fit parameters for the sources is available. The goal of this part of the project is the automatic classification of types of sources,… more

Deformation mechanisms in crystalline solids and Newtonian viscous behavior

Description: The three principal mechanisms of plastic flow in crystalline solids at elevated temperature are crystal slip, grain boundary sliding, and diffusional flow. All three mechanisms involve the diffusion of atoms as the rate-controlling process, either in the lattice or in the grain boundary. Under the correct conditions of microstructure, temperature, and stress, each mechanism can lead to Newtonian-viscous behavior. That is, the strain rate increases linearly with the applied stress. In the case … more
