| Abstract Scope |
Extensive experimental and computational studies have demonstrated outstanding physical and chemical properties of the novel materials of compositionally complex carbides (CCC), enabling their promising applications as next-generation fuel claddings in advanced fast reactors. This presentation provides a comprehensive overview of their radiation damage behavior to understand the fundamental mechanisms related to the impact of multi-principal metal components on phase stability, irradiation-induced defect clusters, irradiation hardening, and thermal conductivity of compositionally complex carbides. Several future research directions are recommended to critically evaluate the feasibility of designing and developing new ceramic materials for extreme environments in fuel claddings using the transformative “multi-principal component” concept. Compared to the existing materials for nuclear applications including stainless steels, nickel alloys, ZrC, SiC, and potentially high-entropy alloys, as well as certain other compositionally complex ceramic families, CCC appear to be more resistant to amorphization, growth of irradiation defect clusters, and void swelling. |
