Thermal conductivity of fully ceramic microencapsulated (FCM) fuel estimation is important to provide accurate prediction of fuel performance and safety aspect of nuclear fuel. ZrO₂-SiC pellets with FCM fuel concept were fabricated using SPS, and characterize using laser flash analysis to measure thermal conductivity. Maxwell-Eucken model that was modified by considering the parameter of matrix-particle interaction was in good agreement with the measured thermal conductivity of ZrO₂-SiC pellets.
