Enabling Computational Technologies for Terascale Scientific Simulations (open access)

Enabling Computational Technologies for Terascale Scientific Simulations

We develop scalable algorithms and object-oriented code frameworks for terascale scientific simulations on massively parallel processors (MPPs). Our research in multigrid-based linear solvers and adaptive mesh refinement enables Laboratory programs to use MPPs to explore important physical phenomena. For example, our research aids stockpile stewardship by making practical detailed 3D simulations of radiation transport. The need to solve large linear systems arises in many applications, including radiation transport, structural dynamics, combustion, and flow in porous media. These systems result from discretizations of partial differential equations on computational meshes. Our first research objective is to develop multigrid preconditioned iterative methods for such problems and to demonstrate their scalability on MPPs. Scalability describes how total computational work grows with problem size; it measures how effectively additional resources can help solve increasingly larger problems. Many factors contribute to scalability: computer architecture, parallel implementation, and choice of algorithm. Scalable algorithms have been shown to decrease simulation times by several orders of magnitude.

Develop Solid State Laser Sources for High Resolution Video Projection Systems (open access)

Develop Solid State Laser Sources for High Resolution Video Projection Systems

Magic Lantern and Honeywell FM and T worked together to develop lower-cost, visible light solid-state laser sources to use in laser projector products. Work included a new family of video displays that use lasers as light sources. The displays would project electronic images up to 15 meters across and provide better resolution and clarity than movie film, up to five times the resolution of the best available computer monitors, up to 20 times the resolution of television, and up to six times the resolution of HDTV displays. The products that could be developed as a result of this CRADA could benefit the economy in many ways, such as: (1) Direct economic impact in the local manufacture and marketing of the units. (2) Direct economic impact in exports and foreign distribution. (3) Influencing the development of other elements of display technology that take advantage of the signals that these elements allow. (4) Increased productivity for engineers, FAA controllers, medical practitioners, and military operatives.

QA Objectives for Nondestructive Assay at the Waste Receiving and Processing (WRAP) Facility (open access)

QA Objectives for Nondestructive Assay at the Waste Receiving and Processing (WRAP) Facility

The Waste Receiving and Processing (WRAP) facility, located on the Hanford Site in southeast Washington, is a key link in the certification of transuranic (TRU) waste for shipment to the Waste Isolation Pilot Plant (WIPP). Waste characterization is one of the vital functions performed at WRAP, and nondestructive assay (NDA) measurements of TRU waste containers is one of two required methods used for waste characterization. The Waste Acceptance Criteria for the Waste Isolation Pilot Plant, DOEMPP-069 (WIPP-WAC) delineates the quality assurance objectives which have been established for NDA measurement systems. Sites must demonstrate that the quality assurance objectives can be achieved for each radioassay system over the applicable ranges of measurement. This report summarizes the validation of the WRAP NDA systems against the radioassay quality assurance objectives or QAOs. A brief description of the each test and significant conclusions are included. Variables that may have affected test outcomes and system response are also addressed.

DEVELOPMENT OF HIGH ACTIVITY, COAL-DERIVED, PROMOTED CATALYTIC SYSTEMS FOR NOx REDUCTION AT LOW TEMPERATURES (open access)

DEVELOPMENT OF HIGH ACTIVITY, COAL-DERIVED, PROMOTED CATALYTIC SYSTEMS FOR NOx REDUCTION AT LOW TEMPERATURES

This project is directed at an investigation of catalytic NO{sub x} reduction mechanisms on coal-derived, activated carbon supports at low temperatures. Promoted carbon systems offer some potentially significant advantages for heterogeneous NO{sub x} reduction. These include: low cost; high activity at low temperatures, which minimizes carbon loss; oxygen resistance; and a support material which can be engineered with respect to porosity, transport and catalyst dispersion characteristics. During the reporting period, TPD studies were conducted following steady-state reaction in NO/CO mixtures in helium. From these studies, the following points have been concluded: (1) The total amount of CO and N{sub 2} evolved following reaction in NO increases with reaction temperature. The TPD spectra are skewed to high temperatures, indicating more stable surface complexes with high desorption activation energies. (2) The total amount of CO evolved following exposure of the char sample to CO at reaction temperatures decreases with reaction temperature, similar to chemisorption behavior. The CO TPD spectra are shifted to lower temperatures, indicating more labile oxygen surface complexes with lower desorption activation energies. (3) The total amount of CO evolved following reaction in NO/CO mixtures decreases with reaction temperature, while the evolved N{sub 2} still increases with reaction temperature. The …

Science and Technology Operations Annual Evaluation of PNNL Environment, Health and Safety, and Facility Operations Performance for FY 1999 (open access)

Science and Technology Operations Annual Evaluation of PNNL Environment, Health and Safety, and Facility Operations Performance for FY 1999

The framework required by P450 5 is clearly in place and includes regular interaction with DOE-RL. There is also a good balance between contractor DOE and other external oversight interactions. The integrated assessment program is fully capable of uncovering weaknesses in performance (e.g. compliance) This point is evidenced by the fact that the contractor has identified most if not all issues prior to that of external sources. However there are also areas for improvement. Self assessments need to be better connected to overall strategy. Varying levels of maturity across management systems exist regarding there ability to assess deployment. There is a need to improve the ability to prioritize and respond to identified opportunities for improvement. There is also a need to improve the integration of assessment results from multiple Self-Assessment plans as well as to improve the integration of the performance of assessments. Finally the partnership between DOE-RL and Battelle must continue to improve DOE RL s development of an appraisal plan early in the fiscal year working in close conjunction with the contractor can further strengthen the assessment program and help ensure that there is the right balance between contractor and external oversight activities and that such activities are …

Simultaneous Production of High-Purity Hydrogen and Sequestration-Ready CO2 from Syngas: Computer Model Development (open access)

Simultaneous Production of High-Purity Hydrogen and Sequestration-Ready CO2 from Syngas: Computer Model Development

Two computer modules are being constructed to model a new process for syngas upgrading and purification. The first module simulates the physical processes occurring in a fluid bed reactor where both gas and solid compositions and flow rates vary significantly along the axis of the reactor. The second module simulates the chemistry and mass transfer between the gas and solid phases. Primitive forms of the two modules have been developed and exercised over a range of performance parameters. These early tests verify that the modules will need to be expanded to model the reactors as series of individual zones in order to attain satisfactory predictive performance.

Silicon-Film{trademark} Solar Cells by a Flexible Manufacturing System: PVMaT Phase II Annual Report, 1 February 1999 - 31 January 2000

AstroPower is developing a manufacturing process for Silicon-Film solar cell production under an NREL-administered Photovoltaic Manufacturing Technology (PVMaT) cost-share program. This document reports on results from the second phase of a three-phase effort. Progress is reported on the development of new procedures and equipment for in-line wet chemical processes, sheet fabrication, solar cell processing, and module assembly. Future concepts and goals for the Silicon-Film process are also discussed. A major technical goal of this effort is the elimination of batch production processes in AstroPower's solar cell process. New processes are being developed that can accommodate large-area Silicon-Film planks in an in-line, continuous manner. During Phase II of this program, an in-line chemical etching system for removing diffusion oxides was specified, procured, and installed. Operation of this system during Phase III of this program is expected to validate the in-line approach and will provide valuable information for use in the design of a second, and more challenging, in-line etch system. Significant progress was made during this reporting period in the development of new screenprinting ink formulations for both the front and back metallization of Silicon-Film solar cells. Cost reductions and efficiency improvements were achieved as a result of these efforts. Progress …

Thin-Film CIGS Photovoltaic Technology: Annual Technical Report-Phase II, 16 April 1999-15 April 2000

A summary of Energy Photovoltaics' Phase II work includes the following: (1) EPV has demonstrated that it can sputter a Mo back-contact capable of supporting very high efficiency cell processing. Using EPV Mo, NREL has deposited a 17.1% CIGS cell (no AR coating). EPV believes it can identify the signature of ``good'' Mo. The Mo was produced on EPV's 0.43 m{sup 2} pilot-line equipment; (2) EPV has performed compound synthesis for several classes of materials, namely non-Cu precursor materials, Cu-containing materials, and ternary buffer materials. Using a ternary compound synthesized at EPV (ZIS) as an evaporation source material for the buffer layer, a Cd-free CIGS device has been produced having an efficiency of 11.5% (560 mV, 32.1 mA/cm{sup 2}, FF 64.3%). The ZIS films are photoconductive, and the devices exhibit no dark-light crossover or light soaking effects; (3) EPV initiated the interest of the University of Oregon in capacitance spectroscopy of CIGS devices. An Urbach tail with characteristic energy E0 < 20meV was identified by transient photocapacitance spectroscopy; (4) Small-area CIGS devices were produced in the pilot-line system with an efficiency of 12.0% (581 mV, 30.1 mA/cm{sup 2}, FF 68.7%), and in an R and D-scale system with 13.3% efficiency …

Development of a magnetic resonance sensor for on-line monitoring of {sup 99}Tc and {sup 23}Na in tank waste cleanup processes: Final report and implementation plan (open access)

Development of a magnetic resonance sensor for on-line monitoring of {sup 99}Tc and {sup 23}Na in tank waste cleanup processes: Final report and implementation plan

In response to US Department of Energy (DOE) requirements for advanced cross-cutting technologies, Argonne National Laboratory is developing an on-line sensor system for the real-time monitoring of {sup 99}Tc and {sup 23}Na in various locations throughout radioactive-waste processing facilities. Based on nuclear magnetic resonance spectroscopy, the highly automated sensor system can provide near-real-time response with minimal sampling. The technology, in the form of a flow-through nuclear-magnetic-resonance-based on-line process sensing and control system, can rapidly monitor {sup 99}Tc speciation and concentration (from 0.1 molar to 10 micro molar) in the feedstocks and eluents of radioactive-waste treatment processes. The system is nonintrusive, capable of withstanding harsh plant environments, and reasonably immune to contaminants. Furthermore, the system is capable of operating over large variations in pH, conductivity, and salinity. This document describes design parameters, results from sensitivity studies, and initial results obtained from oxidation-reduction studies that were conducted on technetium standards and waste specimens obtained from DOE's Hanford site. A cursory investigation of the system's capabilities to monitor {sup 23}Na at high concentrations are also reported, as are descriptions of site requirements, implementation recommendations, and testing techniques.

Supercritical carbon dioxide-soluble ligands for extracting actinide metal ions from porous solids (EMSP Project Number 64965) (open access)

Supercritical carbon dioxide-soluble ligands for extracting actinide metal ions from porous solids (EMSP Project Number 64965)

The objective of this project is to develop novel, substituted diphosphonic acid ligands that can be used for supercritical carbon dioxide extraction (SCDE) of actinide ions from solid wastes. Specifically, selected diphosphonic acids, which are known to form extremely stable complexes with actinides in aqueous and organic solution, are to be rendered carbon dioxide-soluble by the introduction of appropriate alkyl- or silicon-containing substituents. The metal complexation chemistry of these new ligands in SC-CO{sub 2} will then be investigated and techniques for their use in actinide extraction from porous solids developed. This report summarizes the work performed during the first 1.3 years of a 3-year program. Because the planned studies of metal complexation and the development of techniques for actinide removal from solids are dependent on the availability of suitable ligands, efforts to date have focused primarily on the synthesis of selected alkyl- or silicon-containing diphosphonic acids. The authors' principal targets have been derivatives in which the silicon-containing groups either serve as the ester function or are attached to the anchor carbon of the diphosphonic acid. Because methylenediphosphonic acid (MDPA) is commercially available and because its esterification with simple alcohols to yield symmetrical diesters is well-established, their initial studies have focused …

Application of advanced reservoir characterization, simulation, and production optimization strategies to maximize recovery in slope and basin clastic reservoirs, West Texas (Delaware Basin), Class III (open access)

Application of advanced reservoir characterization, simulation, and production optimization strategies to maximize recovery in slope and basin clastic reservoirs, West Texas (Delaware Basin), Class III

The objective of this Class 3 project was to demonstrate that detailed reservoir characterization of slope and basin clastic reservoirs in sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost effective way to recover a higher percentage of the original oil in place through strategic placement of infill wells and geologically based field development. Phase 1 of the project, reservoir characterization, was completed this year, and Phase 2 began. The project is focused on East Ford field, a representative Delaware Mountain Group field that produces from the upper Bell Canyon Formation (Ramsey sandstone). The field, discovered in 1960, is operated by Oral Petco, Inc., as the East Ford unit. A CO{sub 2} flood is being conducted in the unit, and this flood is the Phase 2 demonstration for the project.
