Nuclear Waste Disposal: Designing Materials For the End of Time

May 27, 2015 - May 29, 2015

Centre International Universitaire pour la Recherche
1 rue Dupanloup
45000 Orléans


Convenors :

  • Prof.  Scott Kroeker, LE STUDIUM RESEARCH FELLOW
    FROM Department of Chemistry, Winnipeg, Manitoba, CA
    IN RESIDENCE AT Conditions Extrêmes et Matériaux: Haute Température et Irradiation (CEMHTI), CNRS, Orléans, FR
  • Dr Pierre Florian, Conditions Extrêmes et Matériaux: Haute Température et Irradiation (CEMHTI), CNRS, Orléans, FR


The effective disposal of high-level nuclear waste is a unique challenge due to the extremely long timescale required for some radioactive decay processes. Solutions to this problem require an unprecedented degree of foresight, as materials designed to encapsulate waste products must outlast their creators by many thousands of years. This conference will draw together specialists in various aspects of nuclear waste immobilization ranging from atomic-level characterization of wasteforms to global health and safety. In addition to formal presentations, attendees will be invited to participate in a facilitated discussion focusing on the role of fundamental science in long-term radioactive waste disposal. Thus, speakers will be asked to contribute not only as experts in their own fields, but also as citizens who have thought carefully about the larger societal context of their research. On a philosophical level, this conference may stimulate us to contemplate the limits of science in planning for the unforeseeable future.
