Proceedings from the Workshop on Phytoremediation of Inorganic Contaminants

Description: The Metals and Radionuclides Product Line of the U.S. Department of Energy (DOE) Subsurface Contaminants Focus Area (SCFA) is responsible for the development of technologies and systems that reduce the risk and cost of remediation of radionuclide and hazardous metal contamination in soils and groundwater. The rapid and efficient remediation of these sites and the areas surrounding them represents a technological challenge. Phytoremediation, the use of living plants to cleanup contaminated soils… more

Protocols for Authorized Release of Concrete

Description: Much of the clean or slightly contaminated concrete from Decontamination and Decommissioning (D&D) activities could be re-used. Currently, there is no standardized approach, or protocol, for managing the disposition of such materials. Namely, all potential disposition options for concrete, including authorized release for re-use, are generally not fully evaluated in D&D projects, so large quantities have been unduly disposed of as low-level radioactive waste. As a result, costs of D&D have beco… more

Determination of Transmutation Effects in Crystalline Waste Forms

Description: The overall goal of this project was to study key scientific issues related to the long-term stability and performance of crystalline waste forms under consideration for containment and disposal of nuclear waste. Our research efforts were focused on the effects of transmutation of 137Cs to 137Ba in crystalline pollucite (CsAlSi2O6). This transmutation issue is important to all crystalline nuclear waste forms, including spent fuel. In the research completed, we studied both surrogate samples and… more

Notes on a search for optimal lattice rules

Description: In this paper some of the results of a recent computer search [CoLy99] for optimal three- and four-dimensional lattice rules of specified trigonometric degree are discussed. The theory is presented in a general frame emphasizing the special nature of lattice rules among the rules of specified trigonometric degree.

ANL pre analysis of the SHEBA/CERES experiments.

Description: The French and British nuclear programs have prepared a series of natural uranium oxide fuel samples spiked with small amounts of the individual fission products which makeup a large fraction of the total neutron absorption by fission products in spent nuclear fuel. Both programs have utilized these samples in experimental reactors and have inferred the worth of the individual fission products. These results have been used to validate the cross sections used in criticality safety calculations. … more

OZONE PRODUCTION IN THE PHOENIX URBAN PLUME.

Description: In May and June of 1998, the Department of Energy's Atmospheric Chemistry Program conducted an aircraft and surface based field campaign in Phoenix, Arizona, with the overall goal of obtaining a mechanistic understanding of O{sub 3} formation in the metropolitan area. Participants in the study included scientists from the Arizona Department of Environmental Quality, Argonne National Laboratory, Brookhaven National Laboratory, and Pacific Northwest National Laboratory. On most days, afternoon O{… more

Grid-based asynchronous migration of execution context in Java virtual machines

Description: Previous research efforts for building thread migration systems have concentrated on the development of frameworks dealing with a small local environment controlled by a single user. Computational Grids provide the opportunity to utilize a large-scale environment controlled over different organizational boundaries. Using this class of large-scale computational resources as part of a thread migration system provides a significant challenge previously not addressed by this community. In this pape… more

Runtime checking of datatype signatures in MPI

Description: The MPI standard provides a way to send and receive complex combinations of datatypes (e.g., integers and doubles) with a single communication operation. The MPI standard specifies that the type signature, that is, the basic datatypes (language-defined types such as int or DOUBLE PRECISION), must match in communication operations such as send/receive or broadcast. Because datatypes may be defined by the user in MPI, there is a limitless collection of possible type signatures. Detecting the prog… more

Access Grid: Immersive Group-to-Group Collaborative Visualization

Description: Immersive projection displays have played an important role in enabling large-format virtual reality systems such as the CAVE and CAVE like devices and the various immersive desks and desktop-like displays. However, these devices have played a minor role so far in advancing the sense of immersion for conferencing systems. The Access Grid project led by Argonne is exploring the use of large-scale projection based systems as the basis for building room oriented collaboration and semi-immersive vi… more

Solution to the initial value problem for a high-gain FEL via Van Kampen's method.

Description: Using Van Kampen's normal mode expansion, we solve the initial value problem for a high-gain free-electron laser (FEL) described by the three-dimensional Maxwell-Klimontovich equations. An expression of the radiation spectrum is given for the process of coherent amplification and self-amplified spontaneous emission. It is noted that the input coupling coefficient for either process increases with the initial beam energy spread. The effective start-up noise is identified as the coherent fraction… more
