| Abstract: | The finite element code is used to simulat e the first wall (FW) structure of dual-cooled waste transmutation blanket (DWTB) for the fusion driven sub-critical system (FDS). The temperature and stress fi eld on the condition of different heat loads have been presented. It is shown th at typical Helium gas system can meet the requirement of thermal-hydraulic desi gn. The ability of helium gas removal heat in FW has been analyzed, and the infl uence of the shape of FW flow channel on thermal stress have been considered. |
