Actinide Recovery Using Aqueous Biphasic Extraction: Initial Developmental Studies

Actinide Recovery Using Aqueous Biphasic Extraction: Initial Developmental Studies

Date: August 1992
Creator: Chaiko, David J.; Mensah-Biney, R.; Mertz, C. J. & Rollins, A. N.
Description: Aqueous biphasic extraction systems are being developed to treat radioactive wastes. The separation technique involves the selective partitioning of either solutes or colloid-size particles between two scible aqueous phases. Wet grinding of plutonium residues to an average particle size of one micron will be used to liberate the plutonium from the bulk of the particle matrix. The goal is to produce a plutonium concentrate that will integrate with existing and developing chemical recovery processes. Ideally, the process would produce a nonTRU waste stream. Coupling physical beneficiation with chemical processing will result in a substantial reduction in the volume of mixed wastes generated from dissolution recovery processes. As part of this program, we will also explore applications of aqueous biphasic extraction that include the separation and recovery of dissolved species such as metal ions and water-soluble organics. The expertise and data generated in this work will form the basis for developing more cost-effective processes for handling waste streams from environmental restoration and waste management activities within the DOE community. This report summarizes the experimental results obtained during the first year of this effort. Experimental efforts were focused on elucidating the surface and solution chemistry variables which govern partitioning behavior of plutonium ...

Activities and Operations of the Advanced Computing Research Facility. January 1985 - July 1986

Activities and Operations of the Advanced Computing Research Facility. January 1985 - July 1986

Date: 1986
Creator: Mihaly, Tina & Pieper, Gail W.
Description: This report discusses research activities and operations of the Advanced Computing Research Facility (ACRF) at Argonne National Laboratory from January 1985 through June 1986. During this period, the Mathematics and Computer Science Division (MCS) at Argonne received incremental funding from the Applied Mathematical Sciences program of the DOE Office of Energy Research to operate computers with innovative designs that promise to be useful for advanced scientific research. Over a five-month period, four new commercial multiprocessors (an Encore Multimax, a Sequent Balance 21000, an Aliant FX/8, and an Intel iPSC/d5) were installed in the ACRF, creating a new wave of research projects concerning computer systems with parallel and vector architectures. A list of projects, publications, and users supported by the ACRF is included.

Activities and Operations of the Advanced Computing Research Facility : July - October 1986

Activities and Operations of the Advanced Computing Research Facility : July - October 1986

Date: 1986
Creator: Pieper, Gail W.
Description: Research activities and operations of the Advanced Computing Research Facility (ACRF) at Argonne National Laboratory are discussed for the period from July 1986 through October 1986. The facility is currently supported by the Department of Energy, and is operated by the Mathematics and Computer Science Division at Argonne. Over the past four-month period, a new commercial multiprocessor, the Intel iPSC-VX/d4 hypercube was installed. In addition, four other commercial multiprocessors continue to be available for research - an Encore Multimax, a Sequent Balance 21000, an Alliant FX/8, and an Intel iPSC/d5 - as well as a locally designed multiprocessor, the Lemur. These machines are being actively used by scientists at Argonne and throughout the nation in a wide variety of projects concerning computer systems with parallel and vector architectures.

Addendum to a Proposal for ATLAS: a Precision-Ion Accelerator at Argonne National Laboratory, December 1978

Addendum to a Proposal for ATLAS: a Precision-Ion Accelerator at Argonne National Laboratory, December 1978

Date: 1978
Creator: Argonne National Laboratory
Description: This revised proposal for the construction of the Argonne Tandem-Linac Accelerator System (ATLAS) is in all essentials the same as the proposal originally presented to NUSAC in March 1978. The only differences worth mentioning are the plan to expand the experimental area somewhat more than was originally proposed and an increased cost, brought about principally by inflation. The outline presented is the same (with minor change in wording) as in the original document, reproduced here for the convenience of the reader.
