Abstract
A TRISO architecture including an improved buffer layer is provided. The improved buffer layer contains sacrificial silicon in low density carbon to react with palladium released from the kernel and thereby limit the palladium available to react with the existing SiC layer. The introduction of silicon in the buffer layer allows for longer fuel lifetimes and/or higher operating temperatures. Higher achievable burnups and operational temperatures can reduce fuel costs and achieve higher efficient power production. In addition, the silicon-containing buffer layer mitigates fuel failure from palladium corrosion, thereby increasing the safety of the TRISO fuel particle.
