The Advanced Incineration-Vitrification Hybrid System (SHIVA) process is well suited to treat organic and mineral waste, with high alpha contamination management capabilities. It allows, in a single reactor, waste incineration by a plasma burner and ash vitrification in a cold wall direct glass induction melting system. The SHIVA trial demonstrates the successful processing of an inactive waste stream analogue that contains a mixture of mineral and organic ion exchange media. The waste loading attains a promising value of 38 wt.% and a glass wasteform is obtained. Further, the microstructure, chemical composition, and chemical durability of the wasteform are characterised.
