Abstract
This paper describes the initial results of a 3D flow simulation of a molten glass bath and a transferred electric plasma arc between two aerial metallic electrodes. The calculations were performed as part of a joint CEA-EDF study. The ESTET 3.4 CFD calculation code used to simulate electric arc furnaces in the metallurgical industry was applied here to model glass melting by an oxygen transferred arc plasma in order to optimise the treatment of radioactive waste. This method could be applied to industrial or municipal waste. The high temperature obtained by the plasma allows us to bum the organic fraction of the waste and then, the mineral part of this waste is trapped in me glass melt.
