The finite element code ANSYS is used to calculate the temperature and stressdistributions for the first wall of DFLL-TBM(dual functional lithium lead-test blanket module),for testing in ITER.Preliminary analyses indicate that not only the low temperature design rules,the well-known 3S_m rules,are satisfied for the first wall,but the additional high temperaturestructural design criteria for the creep damage limits and creep-ratcheting limits are met as well.
