Kinetics of Mn-based sorbents for hot coal gas desulfurization. Task 2 -- Exploratory experimental studies: Single pellet tests; rate mechanism analysis. Quarterly report, December 15, 1995--March 15, 1996

Description: Currently, the Morgantown Energy Technology Center, is actively investigating alternative hot fuel gas desulfurization sorbents for application to the Integrated Gasification Combined Cycle (IGCC). A sorbent must be highly active towards sulfur at high temperatures and pressure`s, and under varying degrees of reducing atmospheres. Thus, high conversion of the metal oxide and low hydrogen sulfide exit partial pressures. Also, it must regenerate nearly ideally to maintain activity over numerous c… more

Final report ASTC Program

Description: The specific goals of the ASTC program were: to pilot and administer a year round program to engage and support ethnic minority and women students to enter the pre-college teaching profession; and to develop the ASTC program across California on all twenty CSU campuses. The initial goal of piloting a year round program to engage and support ethnic or underrepresented science students to enter the teaching profession was put in place at CSUS in the Fall of 1993, with the recruitment of students … more

Groundwater maps of the Hanford site, June 1995

Description: The Groundwater Maps of the Hanford Site, June 1995 is a continuation of a series of reports (see Serkowski et al. 1995) that document the configuration of the water table aquifer beneath the Hanford Site (Figure 1). This series presents the results of the semiannual water level measurement program and the water table maps generated from these measurements. The reports document the changes in the groundwater level at the Hanford Site during the transition from nuclear material production to env… more

Comparison of calorimetry and destructive analytical measurement techniques for excess plutonium powders

Description: In Dec. 1994, IAEA safeguards were initiated on inventory of Pu- bearing materials, originating from the US nuclear weapons complex, at vault 3 of DOE`s Plutonium Finishing Plant at Hanford. Because of the diversity and heterogeneity of the Pu, plant operators have increasingly used calorimetry for accountability measurements. During the recent commencement of IAEA safeguards at vault 3, destructive (electrochemical titration) methods were used to determine Pu concentrations in subsamples of in… more

DNFSB Recommendation 94-1 Hanford site integrated stabilization management plan, volumes 1 and 2

Description: This document comprises the Hanford Site Integrated Stabilization Management Plan (SISMP). This document describes the DOE`s plans at the Hanford Site to address concerns identified in Defense Nuclear Facilites Safety Board (DNFSB) Recommendation 94-1. This document also identifies plans for other spent nuclear fuel (SNF) inventories at the Hanford Site which are not within the scope of DNFSB Recommendation 94-1 for reference purposes because of their interrelationship with plans for SNF within… more

Methane Coupling by Membrane Reactor. Quarterly Technical Progress Report, September 25, 1995--December 24, 1995

Description: The performance of the third type of catalytic membrane reactor configuration, with catalyst deposited in the membrane and no catalyst or inert materials in the tube side, was evaluated. The C{sub 2} selectivity obtained was about 10% due to the gas phase reaction in the empty tube side of the reactor. The membrane reactor with an oxygen-permeable dense membrane has been built. The use of a dense membrane will eliminate the loss of hydrocarbon from the tube side to the shell side, as observed i… more

Parallel algorithms for modeling flow in permeable media. Annual report, February 15, 1995 - February 14, 1996

Description: This report describes the application of distributed-memory parallel programming techniques to a compositional simulator called UTCHEM. The University of Texas Chemical Flooding reservoir simulator (UTCHEM) is a general-purpose vectorized chemical flooding simulator that models the transport of chemical species in three-dimensional, multiphase flow through permeable media. The parallel version of UTCHEM addresses solving large-scale problems by reducing the amount of time that is required to ob… more

Immobilization as a route to surplus fissile materials disposition. Revision 1

Description: The safe management of surplus weapons plutonium is a very important and urgent task with profound environmental, national and international security implications. In the aftermath of the Cold War, Presidential Police Directive 13 and various analysis by renown scientific, technical and international policy organizations have brought about a focused effort within the Department of Energy to identify and implement paths forward for the long term disposition of surplus weapons usable plutonium.

Macroscopic traffic modeling with the finite difference method

Description: A traffic congestion forecasting model (ATOP), developed in the present investigation, is described briefly. Several macroscopic models, based on the solution of the partial differential equation of conservation of vehicles by the finite difference method, were tested using actual traffic data. The functional form, as well as the parameters, of the equation of state which describes the relation between traffic speed and traffic density, were determined for a section of the Long Island Expresswa… more

Observations of comet P/Shoemaker-Levy 9 impact on Jupiter from Lick Obseravtory using a high resolution speckle imaging camera

Description: During the week of the impacts of Comet Shoemaker-Levy 9 into Jupiter, we used a speckle imaging camera mounted on the Lick Observatory 3 meter Telescope to record a continuous stream of images of the planet. Because the speckle imaging technique compensates for atmospheric blurring, the resulting images were most likely the highest resolution of any taken from the ground. These images compliment the Hubble Space Telescope data by covering time periods when Hubble was not observing Jupiter. We … more

Novel complexing agents for the efficient separation of actinides and remediation of actinide-contaminated sites

Description: Research into the coordination chemistry of transactinide elements should provide us with new fundamental knowledge about structure, geometry, and stability of these metal complexes. Our approach involves the design, synthesis, and characterization of {open_quotes}expanded porphyrin{close_quotes} macrocyclic ligands which coordinate the actinide metal cations with high thermodynamic affinity and kinetic stability. We can use the knowledge from understanding the fundamental coordination chemistr… more
