摘要： The temperature and strain distributions of the mockup composed of Be, Cu-alloy with distinct structural material (SS316L and China Low Activation martensitic steel (CLAM)) were calculated and analyzed during thermal cycling, based on a high heat flux (HHF) test recently reported with heat flux of 1.5MW/m(2). The calculated temperature and strain results, in which SS316L is as the structural material, showed a good agreement with HHF test. By substituting CLAM steel for SS316L the contrast analysis indicates that the thermo-mechanical property for CLAM steel is better than that of SS316 at the same condition. Furthermore, the temperature and strain distributions of the FW were calculated under the condition of normal ITER operation: the surface heat flux is about 0.5MW/m(2) and volumetric heating due to neutron radiation is on the order of 15 similar to 20 MW/m(2).
