Modélisation numérique de phénomènes couplés dans des bains de verre brassés mécaniquement et élaborés en creuset froid inductif

Abstract : This study reports on a new vitrification process developed by the French Atomic Energy Commission (CEA, Marcoule). This process is used for the treatment of high activity nuclear waste. It is characterized by the cooling of all the metal walls and by currents directly induced inside the molten glass. In addition, a mechanical stirring device is used to homogenize the molten glass. The goal of this study is to develop numerical tools to understand phenomena which take place within the bath and which involve thermal, hydrodynamic and electromagnetic aspects.
The numerical studies are validated using experimental results obtained from pilot vitrification facilities.
