In the past few years, phenanthroline based ligands have become an attractive target for the partitioning of trivalent Actinides (Ac) from Lanthanides (Ln) in nuclear waste management. However, designing efficient...

ABSTRACTThe MRS symposium, “Scientific Basis for Nuclear Waste Management” was first held in Boston, November 28th to December 1st, 1978. This symposium marks the twenty-fifth in a series that now rotate to meeting sites around the world. During the past 24 years, there has been considerable progress in the development and understanding of the behavior of materials that are used in the processing, transport, containment and disposal of radioactive waste. The design and selection of materials for long-term performance has required a uniquely interdisciplinary effort. Over the same period, there have been important developments in the regulatory framework that guides the scientific and engineering needs of nuclear waste management. This paper provides a subjective commentary on the major developments and innovations during the past 25 symposia. The future challenge will be the proper and constructive integration of the science into the development of nuclear waste disposal strategies.

ABSTRACTFirst of all I would like to express my appreciation to the MRS for the opportunity to address this symposium. I am especially pleased to be speaking alongside Charles McCombie and Soren Norrby, who have both made me feel welcome whenever we have met in the past. I have been more active in Sweden over the last few years, as Soren will know. Perhaps it is now time I turned my attentions to Switzerland as well.

AbstractOrganic based ion selective resins have some similar attributes: case of synthesis, high metal ion complexation ability, and flexibility for different nuclear waste management applications. For most chelating polymers, the ligand is deemed to be of primary importance for the interaction with the targeted metal ion. The role of the polymer matrix is usually ignored. For ion specific resins, the polymer structure is formed to a specific metal ion. Using the molecular imprinting technique, resins can be formed with functional groups and cavities for a target metal ion. Ion selective resins have been developed for the separation of Cs. The methods and concepts used for the development of the Cs specific resins have been applied to the development of selective resins for Eu (a trivalent actinide model). The resulting resins are characterized by FTIR spectroscopy, moisture regain, and ion exchange capacity. The incorporation of 8-hydroxyquinoline into the resin increases selectivity for Eu over La. The results for the Eu study indicate ion specific resins can be developed for the separation of trivalent actinides from nuclear waste.

Excellent Work

The symposium “Scientific Basis for Nuclear Waste Management XVII” was held in June 15 – 19, 2003, in Kalmar, Sweden. The symposium, which was officially opened by the County Govenor of Kalmar County, Sven Lindgren, attracted 222 participants from 21 countries. Nearly 200 papers were presented during the three days of scientific sessions.Organizing a symposium this size requires the assistance of a large number of people involved both in establishing the scientific program and in planning and executing the practical organizational arrangements. Our window to the world, the symposium's homepage, was continuously kept up to date through the excellent work of Jonny Rönnfjord.
