文摘

SiC cladding designs are optimized with a multi-layer structural analysis code. Layer radial thickness fraction that minimizes cladding fracture probability exists. The demonstrated procedure is applicable for multi-layer SiC cladding design. Duplex SiC with the inner composite fraction ∼0.4 is optimal in a reference case. Increasing composite thermal conductivity markedly decreases SiC cladding stress.
