Physical Design of High-Performance Fuel Assembly Based on Fully Ceramic Microencapsulated Fuel for Supercritical CO2 Cooled Reactor

Fully ceramic microencapsulated fuel (FCM) is employed in the supercritical CO2 (S-CO2)-cooled reactor as accident tolerant fuel (ATF). Although the fuel and the assembly substrate contain SiC, the assembly cannot be sufficiently moderated due to the weak moderating performance of S-CO2, which affec...
