Evaluation of Effectiveness of the Turco Low Profile Turbulator Reg Sign

Description: This document discusses a turbulator which utilizes a heated chemical bath to reduce smearable contamination from small parts and tools. It is comprised of two agitators programmed to automatically alternate the flow of the cleaning solution within the tank in four separate and distinct high velocity flow patterns allowing access to the entire surface area of the part or tool being decontaminated. The turbulator is being evaluated to determine if agitation increases the effectiveness of waste m… more

A novel process for manufacture of methanol

Description: A bench-scale reactor is being used to conduct studies of the conversion of synthesis gas to methanol by a novel process. During the last quarter, the effect of potassium methoxide and Cu-chromite loading on the MeOH formation rate was investigated. The rate obtained with Cu-chromite was compared to that using Cu-ZnO as catalyst. Work also continued on the modification of the experimental equipment to permit on-line monitoring of liquid and gas compositions.

Spectroscopic diagnostics of high temperature plasmas

Description: A three-year research program for the development of novel XUV spectroscopic diagnostics for magnetically confined fusion plasmas is proposed. The new diagnostic system will use layered synthetic microstructures (LSM) coated, flat and curved surfaces as dispersive elements in spectrometers and narrow band XUV filter arrays. In the framework of the proposed program we will develop impurity monitors for poloidal and toroidal resolved measurements on PBX-M and Alcator C-Mod, imaging XUV spectromet… more

Control of energetic ion confinement by ion cyclotron range of frequency waves

Description: It is shown that ICRF waves can induce fast convective radial transport of energetic ions in a tokamak geometry without affecting the background ion transport. Spatially inhomogeneous ICRF waves with directional parallel wave vectors are needed; otherwise, a net parallel flow of the energetic ions has to be present. 8 refs.

ASHRAE Standard 62-1989: Energy, Cost, and Program Implications.

Description: ASHRAE Standard 62-1989 (Standard 62-89) Ventilation for Acceptable Indoor Air Quality'' is the new heating, ventilating, and air-conditioning (HVAC) industry consensus for ventilation air in commercial buildings. Bonneville Power Administration (Bonneville) references ASHRAE Standard 62-81 (the predecessor to Standard 62-89) in their current environmental documents for required ventilation rates. Through its use, it had become evident to Bonneville that Standard 62-81 needed interpretation. No… more

F-Area seepage basins, groundwater quality assessment report, first quarter 1990

Description: During the first quarter of 1990, wells which make up the F-Area Seepage Basins (F-HWMF) monitoring network were sampled.

The primary contaminants observed at wells monitoring the F-Area Seepage Basins are tritium, nitrate, cadmium, lead, total radium, gross alpha, and nonvolatile beta. Concentrations of at least one of the following constituents: tri… more

New approaches to linear and nonlinear programming

Description: During the last twelve months, research has concentrated on barrier- function methods for linear programming (LP) and quadratic programming (QP). Some ground-work for the application of barrier methods to nonlinearly constrained problems has also begun. In our previous progress report we drew attention to the difficulty of developing robust implementations of barrier methods for LP. We have continued to refine both the primal algorithm and the dual algorithm. We still do not claim that the barr… more

Three-dimensional contaminant plume dynamics in the vadose zone: Simulation of the 241-T-106 single-shell tank leak at Hanford

Description: Approximately 2,000 m{sup 3} of liquid containing radioactive and chemical wastes leaked from the 241-T-106 single-shell tank at the Hanford Site. The leak discharged into the unsaturated, coarse-grained sediments of the Hanford formation which underlie the base of the tank. The PORFLO-3 computer code was used to study plume migration for {sup 106}Ru and {sup 137}Cs. The flow and transport properties of the soils through which the plume has migrated are critical input data for the model but are… more

Annular Flow Distribution test

Description: This report documents the Babcock and Wilcox (B W) Annular Flow Distribution testing for the Savannah River Laboratory (SRL). The objective of the Annular Flow Distribution Test Program is to characterize the flow distribution between annular coolant channels for the Mark-22 fuel assembly with the bottom fitting insert (BFI) in place. Flow rate measurements for each annular channel were obtained by establishing hydraulic similarity'' between an instrumented fuel assembly with the BFI removed an… more

Critical heat flux concerns during the flow instability phase of a DEGB LOCA

Description: Arguments are presented that support the proposal that a separate burnout risk analysis, for the Flow Instability (FI) phase of a LOCA, not be required for reactor restart. With expected reactor power limits, flow instability will occur before critical heat flux (CHF). Since FI power limits preclude the occurrence of flow instability in a bounding accident, a DEGB LOCA, the risk of CHF and attendant burnout is negligible. A review of RDAP data revealed that in the past reactor assemblies operat… more

Simulations of plasma performance in a beam-driven tokamak fusion reactor with Q approx 2-3

Description: Supershot profiles were used to simulate plasmas in a neutral-beam driven tokamak reactor designed to achieve fusion energy production with Q {approx} 2-3. Profiles from a TFTR supershot were scaled to larger radii, density, and electron temperature. The TRANSP code was used to calculate performance of these plasmas. Examples are given of steady-state plasmas with large beam-driven bootstrap currents. The required energy transport rate is comparable to that in TFTR, but the particle transport r… more

A review of the environmental behavior of uranium derived from depleted uranium alloy penetrators

Description: The use of depleted uranium (DU) penetrators as armor-piercing projectiles in the field results in the release of uranium into the environment. Elevated levels of uranium in the environment are of concern because of radioactivity and chemical toxicity. In addition to the direct contamination of the soil with uranium, the penetrators will also chemically react with rainwater and surface water. Uranium may be oxidized and leached into surface water or groundwater and may subsequently be transport… more

Mechanism for the selective conjugation of ubiquitin to phytochrome

Description: The goal of this project is to understand at the molecular level how phytochrome functions and how intracellular proteins are degraded. Phytochrome is marked for degradation by covalent attachment of ubiquitin. Ubiquitin-phytochrome conjugates (UbP) were characterized with respect to formation kinetics, subcellular localization and site of ubiquitin attachment. UbP appears to be a general phenomenon during phytochrome degradation in a variety of species. UbP was isolated from oat seedlings and … more
