New vitrification techniques

Conference:

Abstract

The Commissariat a l`Energie Atomique (CEA) has developed a new direct-induction cold-crucible glass melting technique to the industrial stage. Process equipment is no longer subject to previous limitations on the glass melting temperature and capacity, making it possible in future facilities to vitrify not only high-level but also low- and intermediate-level liquid wastes. In the new vitrification facilities the liquid evaporation capacity has been increased by adding a head-end concentration step prior to calcining, and by increasing the calciner evaporation capacity. Vitrification furnace performance has been enhanced by increasing the melting capacity as well as the melting temperature to produce a wider range of glass formulations. Consequently, liquid waste vitrification now includes two types of facilities for high-level wastes and for low-to intermediate-level wastes.
