Additive manufacturing (AM) methods are currently being explored for applications in nuclear reactors to make advanced reactors more efficient, safe, and reliable. The Transformational Challenge Reactor (TCR) program has explored AM for nuclear by designing a high-temperature gas reactor (HTGR) using an AM silicon carbide fuel form with uranium nitride–tristructural isotro…

A sensitivity analysis on the failure probability of the Silicon Carbide (SiC) layer in tristructural isotropic (TRISO) nuclear fuel during transient conditions predicted by the BISON fuel performance code is performed. The principal goal of the analysis is to understand the most important parameters dictating SiC failure behavior in BISON during Reactivity Initiated Accid…

A new concept for LWR nuclear fuel utilizes tri-structural isotropic (TRISO) fuel particles embedded in a SiC matrix in pellet form, termed fully-ceramic micro-encapsulated fuel (FCM), replacing sintered urania pellets. As part of assessing this concept, thermomechanical analysis of the LWR application of TRISO fuel with UN kernels was performed. Fission product release fr…
