We have been developed a thermal-hydraulic and mechanical coupling evaluation method for BWR plant transient and safety analysis using SiC clad fuel which is a candidate for ATF. In typical DBA conditions, we assumed that there is not so much difference in the mechanical behavior between SiC clad fuel and Zry clad fuel.
