Abstract
During thermal testing of high-temperature gas-cooled reactor (HTGR) oxide-based fuel, unexpected particle bursting phenomena were observed which suggest a mechanism of failure propagation between neighboring particles. This paper proposed a theory that the oxide kernel in the initially failed particle migrates through its surrounding coatings, including the SiC, and reacts by carbothermic reduction with the outer pyrocarbon coating of a nearby particle.
