This paper considers options for using glass ceramics based on silicon dioxide as a promising material for nuclear power engineering, in particular, as shells and containers when handling liquid radioactive waste (LRW) and solid radioactive waste (SRW); canisters, ampules, and other shells for hermetic isolation from the environment of spent nuclear fuel (SNF) or irradiated fuel assemblies (IFAs); crucibles and vessels for melting, compacting, and disposing SRW; and hermetic shells or liners using composite combinations of glass ceramics and traditional materials to create special containers that provide long-term (more than 1000 years) storage or disposal of SNF. Methods for obtaining large-sized products from silicon-containing glass–ceramic materials are presented. Thermophysical calculations are carried out, which showed that the most favorable indicators for the state of temperature fields can be achieved in canisters made of hexagonal-shaped glass–ceramic materials for IFAs with the smallest possible volume of the gas cavity.
