| Abstract Scope |
Nuclear energy continues being an important baseline electricity source with the minimal carbon footprint. In pursuit of inherently safe and economical nuclear energy, development of SiC-based ceramic matrix composite materials continues as the enabling technology for accident-tolerant fuels and core structures for the current fleet and future reactors. The recent research and development focuses include the mechanisms of and mitigation for potential hermeticity compromise, oxidation and environmentally assisted failure in the severe accident conditions, integrated in-pile testing of surrogate and fueled rodlets, and the other technical basis toward the lead test rod program. This paper overviews the recent development of materials and technologies and discusses the needs and opportunities for materials science and engineering research.
