Description
Lead−lithium (Pb−Li) alloy are considered as a coolant and a tritium breeder for fusion reactor blanket systems. One of the critical requirements for the realization of this systems is the compatibility of silicon carbide (SiC) and its composites as structural and/or functional materials. The authors investigated that inclusions, possibly Li−oxides in Pb−Li may have certain impacts on compatibility of the materials through reactions with oxides in/on materials even if the oxygen level in Pb−Li is low. This study aims to clarify the degradation behavior of CVI−SiC with liquid Pb−Li using rotating disk systems under rotating flow condition at 700°C up to 3,000h.
Key-words: silicon carbide (SiC), chemical vapor deposition (CVD), chemical vapor infiltration (CVI), liquid breeding material, Pb–Li, rotating flow condition
