Incineration and vitrification of surrogate nuclear wastes by thermal plasma

The aim of this presentation is to demonstrate the feasibility to substitute a single plasma reactor, where the arc is transferred on a melt glass bath, for existing several steps nuclear technological wastes incinerator. The incineration of wastes, the produced gases treatment and the vitrification of ashes issues from wastes incineration are the three simultaneous functions of this new kind of reactor. The three steps of the work are described: first, the postcombustion in an oxygen plasma of gases generated from the waste pyrolysis, then, the vitrification of ashes issued from calcination of wastes in the transferred plasma furnace and finally, the incineration/vitrification of wastes in the same furnace.
