Assessing DNAPL contamination, A/M-Area, Savannah River Site: Phase 1 results

Description: The primary objective of the Phase I dense non-aqueous phase liquid (DNAPL) characterization discussed in this document was to assess the status of DNAPL beneath A/M-Area at the Savannah River Site (SRS). The initial characterization phase consisted of: (1) geological data collection to more precisely define the controlling geologic features, and (2) physical/chemical measurements in existing wells. Additionally, background and historical information from the unit (e.g., operating history and d… more

Verification of frequency scaling laws for capacitive rf discharges using two-dimensional simulations

Description: Weakly ionized processing plasmas are studied in two-dimensions using a bounded particle-in-cell (PIC) simulation code with a Monte Carlo Collision (MCC) package. The MCC package models the collisions between charged and neutral particles, which are needed to obtain a self-sustained plasma and the proper electron and ion energy loss mechanisms. A two-dimensional capacitive RF discharge is investigated in detail. Simple frequency scaling laws for predicting the behavior of some plasma parameters… more

Fluid simulations of {nabla}T{sub e}-driven turbulence and transport in boundary plasmas

Description: It is clear that the edge plasma plays a crucial role in global tokamak confinement. This paper is a report on simulations of a new drift wave type instability driven by the electron temperature gradient in tokamak scrapeoff-layers (SOL). A 2d fluid code has been developed in order to explore the anomalous transport in the boundary plasmas. The simulation consists of a set of fluid equations for the vorticity {nabla}{sub {perpendicular}}{sup 2}{phi}, the electron density n{sub c} and the temper… more

Monitoring the response of the upper troposphere/lower stratosphere to a greenhouse gas scenario. Final progress report, May 1, 1990--December 15, 1992

Description: During the past two years a system has been under development to contribute to this monitoring process by making measurement of the downwelling infrared radiance field at moderate spectral resolution. Sensitivity of the measurements to the presence of cirrus cloudiness, and effective particle size in cirrus clouds has been demonstrated. Sensitivity of the measurements to concentration of C0{sub 2} and to the gross temperature structure of a 2CO{sub 2} atmosphere have been modeled, and measureme… more

Liquid chromatographic analysis of coal surface properties. Quarterly progress report, July--September 1992

Description: Experiments on equilibrium adsorption of various alcohols on 60--200 mesh Illinois No. 6 coal (DECS-2; Randolph county) were performed during the July--September period. The alcohols include ethanol, methanol, isobutanol, t-butanol, 1-heptanol, 1-octanol, 1-hexadecanol, 4-methyl-2-pentanol, and 2-methyl-l-pentanol. Amounts of equilibrium adsorption of alcohols (ALCO) on 60--200 mesh Illinois No. 6 coal are 1 - 230 {times} 10{sup {minus}6} mg-ALCO/g-coal, whereas equilibrium concentrations of al… more

Theory and simulation of plasma sheath waves

Description: Sheath waves have been investigated analytically and with particle simulation for an unmagnetized two dimensional plasma slab with periodic boundary conditions in y and conducting walls at x = 0, L{sub x}. Analytically treating the sheath as a vacuum layer, the sheath wave bears a resemblance to plasma vacuum surface waves. The simulations are in agreement with the theory for both bulk Bohm Grow waves and edge sheath waves, with some unanswered questions. Some waves that were expected did not s… more

Electron temperature gradient driven instability in the tokamak boundary plasma

Description: A general method is developed for calculating boundary plasma fluctuations across a magnetic separatrix in a tokamak with a divertor or a limiter. The slab model, which assumes a periodic plasma in the edge reaching the divertor or limiter plate in the scrape-off layer(SOL), should provide a good estimate, if the radial extent of the fluctuation quantities across the separatrix to the edge is small compared to that given by finite particle banana orbit. The Laplace transform is used for solving… more

The Listing of a Species: Legal Definition and Biological Realities

Description: The 103d Congress will debate the reauthorization of the Endangered Species Act (ESA) 2 which expired on October 1, 1992. The Act has recently generated controversy, even though it passed in 1973 with virtually no opposition. Much of the debate concerns specific actions that would jeopardize particular species or populations. However, the controversy has been fueled by the discrepancies between two sets of legal definitions and the subtle biological realities that they approximate

VEPCO network model reconciliation of LANL and MZA model data

Description: The LANL DC load flow model of the VEPCO transmission network shows 210 more substations than the AC load flow model produced by MZA utility Consultants. MZA was requested to determine the source of the difference. The AC load flow model used for this study utilizes 2 standard network algorithms (Decoupled or Newton). The solution time of each is affected by the number of substations. The more substations included, the longer the model will take to solve. In addition, the ability of the algorit… more
