Sumglass 2023

Sumglass 2023 aims to bring together the research and industrial communities of the glass sector.

This summer school will allow to share the issues and methodologies developed on the vitrification of nuclear wastes and on the manufacture and properties of industrial glasses. New advances in terms of modeling and simulation developed on spatial and temporal scales will be discussed, both to follow glass vitrification process and the behaviour of glass during its life cycle.

International specialists will present reviews or keynotes. A call for abstracts will be proposed for a poster session covering all the topics addressed in the summer school.


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 behaviour of glasses opens up a major field of innovation to achieve the carbon neutrality objectives (wind, solar, hydraulic, hydrogen, nuclear) of the energy transition. Whether in the nuclear sector or in the glass industry, R&D is focused on optimizing the quality of glass products, matching their behaviour to their conditions of use, while minimising 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 on the experimental and modelling levels, in a very wide range of applications (tableware, flat glass, glass packaging, nuclear glass, glass fibers for reinforcement or insulation, bioglass…). The main issues related to modeling and simulation approaches will be discussed during this summer school.
