SumGlass 2023
3rd Summer School on nuclear and industrial glasses for energy transition
September 25-29th 2023 – Occitanie region (France)
Organized by CEA/DES/ISEC/DE2D

Local organizing committee:,,,,,

SumGlass 2023 aims to bring together the research and industrial communities of the glass sector. This summer school will allow to share the problems and methodologies developed on the vitrification of nuclear waste and on the manufacture and properties of industrial glass. New advances in terms of modeling and simulation developed on spatial and temporal scales will be discussed, both to follow the glass synthesis in furnaces and to understand the behavior of glass during its life cycle.

International specialists will present reviews and Keynotes. A call for abstracts will be made for a special session dedicated to industrial issues, as well as poster sessions covering all the topics addressed in the summer school.


  • Nuclear, industrial wastes and recycling
  • Industrial vitrification technologies
  • Glass waste form and issues
  • Methodologies developed for nuclear glasses and glasses for energy transition
  • New advances on glass melting modeling
  • Modeling of chemical mechanism in melt
  • Behavior of glass alteration in use

Context : The R&D issues raised by the nuclear industry have made it possible to meet major challenges, particularly in the field of radioactive waste vitrification. The unique know-how developed over more than 60 years in various nuclear waste vitrification technologies and in the formulation, physical and chemical properties and long-term behavior of glasses opens up a major field of innovation to achieve the carbon neutrality objectives (wind, solar, hydraulic, hydrogen, nuclear) for the energy transition. Whether in the nuclear sector or in the glass industry, R&D is focused on optimizing the quality of glass products, in adequacy with their behavior to their conditions of use, while minimizing the environmental impact over their entire life cycle.  It is crucial to better understand their properties, but also to be able to minimize waste and the use of primary resources without degrading product properties. Numerous projects are being carried out, both experimental and modeling, in a very wide range of applications (tableware, flat glass, glass for bottles, packaging, nuclear glass, glass fibers for reinforcement or insulation). Modeling and simulation approaches are in full expansion to address the various issues.
