1997 toxic chemical release inventory -- Emergency Planning and Community Right-To-Know Act, Section 313 (open access)

1997 toxic chemical release inventory -- Emergency Planning and Community Right-To-Know Act, Section 313

Two listed toxic chemicals were used at the Hanford Site above established activity thresholds: phosphoric acid and chlorine. Because total combined quantities of chlorine released, disposed, treated, recovered through recycle operations, co-combusted for energy recovery, and transferred to off-site locations for the purpose of recycle, energy recovery, treatment, and/or disposal, amounted to less than 500 pounds, the Hanford Site qualified for the alternate one million pound threshold for chlorine. Accordingly, this Toxic Chemical Release Inventory includes a Form A for chlorine, and a Form B for phosphoric acid.

Accelerating cleanup: Paths to closure (open access)

Accelerating cleanup: Paths to closure

This document was previously referred to as the Draft 2006 Plan. As part of the DOE`s national strategy, the Richland Operations Office`s Paths to Closure summarizes an integrated path forward for environmental cleanup at the Hanford Site. The Hanford Site underwent a concerted effort between 1994 and 1996 to accelerate the cleanup of the Site. These efforts are reflected in the current Site Baseline. This document describes the current Site Baseline and suggests strategies for further improvements in scope, schedule and cost. The Environmental Management program decided to change the name of the draft strategy and the document describing it in response to a series of stakeholder concerns, including the practicality of achieving widespread cleanup by 2006. Also, EM was concerned that calling the document a plan could be misconstrued to be a proposal by DOE or a decision-making document. The change in name, however, does not diminish the 2006 vision. To that end, Paths to Closure retains a focus on 2006, which serves as a point in time around which objectives and goals are established.

Biological dosimeter for cellular damage and repair by ionizing radiation. Final technical progress report, May 1, 1993--April 30, 1996 (open access)

Biological dosimeter for cellular damage and repair by ionizing radiation. Final technical progress report, May 1, 1993--April 30, 1996

The authors have investigated the alteration of chromatin domains in Human T and B cells after ionizing radiation using three DNA specific dyes, Feulgen, Hoechst and 7-amino actinomycin D. Characterization and differentiation of T and B cells was accomplished using only 4 of a possible 32 image features with the CAS and Quaritex QX7 Digital Image Systems. Human B and T cells were irradiated with 1, 5 and 10 Gy and analyzed during a 1.5 hour recovery period. The chosen features detect a dose dependent change in DNA domains which can be observed as early as 1.5 hours after a 1Gv exposure. The results suggest that the ability of DNA specific dyes to stain chromatin can be used as an early sensitive indicator of DNA damage. The observed alteration of chromatin staining suggests that chromatin structure does observably change in a significant manner during a DNA repair interval. Since these alteration can be detected with DNA specific dyes that stain both AT rich, GC rich or total DNA, these data suggest that a global alteration of the chromatin is occurring after exposure to ionizing radiation.

Coupling 2-D cylindrical and 3-D x-y-z transport computations (open access)

Coupling 2-D cylindrical and 3-D x-y-z transport computations

This paper describes a new two-dimensional (2-D) cylindrical geometry to three-dimensional (3-D) rectangular x-y-z splice option for multi-dimensional discrete ordinates solutions to the neutron (photon) transport equation. Of particular interest are the simple transformations developed and applied in order to carry out the required spatial and angular interpolations. The spatial interpolations are linear and equivalent to those applied elsewhere. The angular interpolations are based on a high order spherical harmonics representation of the angular flux. Advantages of the current angular interpolations over previous work are discussed. An application to an intricate streaming problem is provided to demonstrate the advantages of the new method for efficient and accurate prediction of particle behavior in complex geometries.

Engineered materials characterization report, volume 3 - corrosion data and modeling update for viability assessments (open access)

Engineered materials characterization report, volume 3 - corrosion data and modeling update for viability assessments

This Engineered Materials Characterization Report (EMCR), Volume 3, discusses in considerable detail the work of the past 18 months on testing the candidate materials proposed for the waste-package (WP) container and on modeling the performance of those materials in the Yucca Mountain (YM) repository setting This report was prepared as an update of information and serves as one of the supporting documents to the Viability Assessment (VA) of the Yucca Mountain Project. Previous versions of the EMCR have provided a history and background of container-materials selection and evaluation (Volume I), a compilation of physical and mechanical properties for the WI� design effort (Volume 2), and corrosion-test data and performance-modeling activities (Volume 3). Because the information in Volumes 1 and 2 is still largely current, those volumes are not being revised. As new information becomes available in the testing and modeling efforts, Volume 3 is periodically updated to include that information.

ENGINEERING DEVELOPMENT OF SLURRY BUBBLE COLUMN REACTOR (SBCR) TECHNOLOGY (open access)

ENGINEERING DEVELOPMENT OF SLURRY BUBBLE COLUMN REACTOR (SBCR) TECHNOLOGY

The major technical objectives of this program are threefold: (1) to develop the design tools and a fundamental understanding of the fluid dynamics of a slurry bubble column rector to maximize reactor productivity, (2) to develop the mathematical reactor design models and gain an understanding of the hydrodynamic fundamentals under industrially relevant process conditions, and (3) to develop an understanding of the hydrodynamics and their interaction with the chemistries occurring in the bubble column reactor. Successful completion of these objectives will permit more efficient usage of the reactor column and tighter design criteria, increase overall reactor efficiency, and ensure a design that leads to stable reactor behavior when scaling up to large diameter reactors.

EXPLORATORY RESEARCH ON NOVEL COAL LIQUEFACTION CONCEPT (open access)

EXPLORATORY RESEARCH ON NOVEL COAL LIQUEFACTION CONCEPT

All first-stage experimental tests were completed for Task 4 (and the Contract). The first-stage one-liter autoclave tests that were made were duplicates of Run 41-LA. The conditions used were chosen last quarter to reduce the cost of the first-stage of the process from those used at the conclusion of Task 3. Filtration and second-stage tests were made using the products of the first-stage tests. Post-second-stage filtration, tested as an alternative to interstage (pre-second- stage) filtration, resulted in low filtration rates. Different catalyst loadings and type and residence time for second-stage hydrotreating were explored. Longer residence times did not result in significantly more resid conversion. Higher catalyst loadings were more effective in converting the resid at the same residence time. The material and elemental balances for the first-stage were completed. The material and elemental balances for the second-stage were initiated.

Final Report: Acidic Properties of Doped Aerogels, April 19, 1993 - June 30, 1998 (open access)

Final Report: Acidic Properties of Doped Aerogels, April 19, 1993 - June 30, 1998

Over this grant period we have studied extensively zirconia and alumina aerogels doped with a wide variety of dopants including silica, sulfate, phosphate, tungstate and combinations thereof. These results have deepened our understanding of the effects of dopants on acidic properties, which is the main goal of the project, and in particular led to the development of a hierarchy with which the Broensted acid strength of different samples can be meaningfully compared. We provide a more detailed description of several specific systems.

Final Report: Tolerance to phytoalexins and its implication for the evolution of host specific virulence traits, July 1, 1996 - June 30, 1998

This research focused on determining the importance of non-degradative tolerance (NDT) to pisatin for the virulence of N. haematococca MPVI on pea. An attempt was also made to determine the importance of pda for virulence of F. oxysporum f.sp.pisi,A. pisi and M. pinodes. This research aided in refining the author's understanding of those characteristics of the pda genes that contribute to virulence and the role of non-degradative tolerance in the virulence of other pea pathogens.

Food Stamp Benefits for Legal Immigrants in P.L. 105-185

The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA; P.L. 104-193) established significant new restrictions on the eligibility of legal immigrants, or "qualified aliens," for needs-based public assistance.' Previously, legal immigrants were eligible for public assistance on much the same basis as citizens. Food stamp eligibility will be provided for approximately 250,000 legal immigrants under P.L. 105-185, the "Agricultural Research, Extension, and Education Reform Act of 1998," at a cost of $818 million for FY1999-FY2003. The food stamp eligibility provisions took effect on November 1, 1998.

Heat transfer at the mold-metal interface in permanent mold casting of aluminum alloys project. Quarterly project status report, April 1--June 30, 1998 (open access)

Heat transfer at the mold-metal interface in permanent mold casting of aluminum alloys project. Quarterly project status report, April 1--June 30, 1998

Extensive progress in development of an HTC (heat transfer coefficient) Evaluator and in the preparation of the experiments at CMI and Amcast have been achieved in the last three months. The interface of the HTC Evaluator has been developed in Visual C++ for the PC platform. It provides a tool to collect and store the published data on heat transfer coefficients in a database for further analysis. It also supports the mathematical model for evaluation of heat transfer coefficients. More than 100 papers related to this project have been cited and most of them have been collected. The preparation of the experiments at CMI is almost completed. A hockey-puck mold has been selected for the experiments for squeeze casting and semi-solid casting. A direct cavity pressure measurement system was purchased from Kistler. The pressure probes and data acquisition software as well as the necessary accessories have been delivered. The instrumented mold modification has been designed and the modifications completed. At Amcast Automotive, a new wheel-like mold for low-pressure permanent mold casting was designed. The CAD file for mold fabrication has been generated. The modeling of the casting has been done. An extensive survey on the ultrasonic gap formation measurement was …

Hydro schemes and reactive flow in 1-d and 2-d (open access)

Hydro schemes and reactive flow in 1-d and 2-d

The behavior of the implementation of Craig Tarver's reactive flow model for high explosives in a hydro code is investigated. The model produces the correct shock propagation rates. The effects of geometry, zoning and artificial viscosity are compared in one (1D) and two (2D) dimensions. Sensitivities to the solution scheme of the hydro equations are also investigated. A comparison with an experimentally verified, analytic theory is presented for the speed of spherically diverging reactive flow fronts. We show that for LX-14 the reactive flow results obey that theory and a lag of about 1.5 to 2.0 mm is produced in a spherical system in about 5 cm of travel from the origin compared to programmed burn. Reactive flow is shown to produce a more strongly developed Mach stem than does conventional, programmed lighting assisted by beta burn. The reactive flow results appear to be close to convergence for zone sizes of 1/16 mm. Several numerical anomalies in code/model behavior are shown and their limited effects are discussed. Some one-dimensional results for LX-17 are also briefly discussed.

Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance (open access)

Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance

Integrated Approach Towards the Application of Horizontal Wells to Improve Waterflooding Performance scanner logs through a newly drilled well. By combining the state-of-the-art data with conventional core and log data, we developed a detailed reservoir description based on an integrated approach. After conducting extensive reservoir simulation studies, we evaluated alternate reservoir management strategies to improve the reservoir performance including drilling of a horizontal injection well. We observed that selective completion of many wells followed by an increase in the injection rate was the most feasible option to improve the performance of the Self Unit. This management plan is currently being implemented and the performance is being Stage II of the project will involve selection of part of the same reservoir (Berryhill Unit - Tract 7), development of reservoir description using only conventional data, simulation of flow performance using developed reservoir description, selection of an appropriate reservoir management plan, and implementation of the plan followed by monitoring of reservoir performance. During the summer of 1995, we started implementing the reservoir management plan in the Self Unit. Last quarter, after evaluating each individual well, we decided to install electrical submersible pumps to produce three wells. The other three wells required the use …
