| Abstract Scope |
Tri-Structural Isotropic (TRISO) fuels are advanced nuclear fuels that have the potential to be utilized in various types of Generation IV reactors due to their high operating temperatures, efficiency, and versatility. TRISO particles are often used in graphite matrix fuel concepts, and while these fuels have significant utility, there remains some uncertainty about their abilities due to a lack of accurate local thermal conductivity measurements of the graphite matrix that holds the TRISO particles. In order to characterize the thermal conductivity with respect to graphite orientation, synthetic microstructures of the TRISO fuel compact have been combined with constitutive thermal conductivity models to perform finite element analysis in COMSOL. This allows for the determination of the effective properties of the fuel with uncertainty quantification, which yields a more accurate understanding of the graphite structure and properties of the TRISO fuel form. |
