Consolidation of HLW into Mineral-Like Materials by the SHS

Article Preview

Abstract:

Samples of mineral-like materials based perovskite and model high-level wastes (strontium) were fabricated by the SHS-densification and tested. The results of MCC-1, XRD and SEM/EDS analysis show that the major phase is well concordant with the design. The samples were characterized by dense structure and fine chemical stability. It is a durable material with high-level waste loading and is in favor for final geological disposal.
