The Chemistry of Advanced Nuclear Systems: Separations
The symposium will provide a forum for computational and experimental researchers from these and other institutions to share their progress on these issues, foster collaborative relationships, and address future areas of interest. There will be 4 umbrella topics, one for each half-day session. These will include: 1) Environmental Actinide Chemistry, 2) Theoretical modeling and simulation of heavy elements and new materials for nuclear systems applications, 3) Separations for spent fuel processing, and 4) fuels and waste forms, including material performance under radiative fields.
Sponsor: American Chemical Society and AAAS Pacific Division
