Creep-fatigue damage evaluation of DHX (Decay Heat Exchanger) and AHX(Air Heat Exchanger) in the sodium test facility has been performed. The sodium test loop of the STELLA-1 is for component performance tests of the main components, heat exchangers and mechanical pumps which are to be installed in an integral sodium test loop (STELLA-2) for simulating thermal hydraulic decay heat removal behaviour of the Korean demonstration Sodium-cooled Fast Reactor. High temperature design and fabrication of the DHX and AHX have been conducted and the components were installed at KAERI site. Evaluation of creep-fatigue damage at critical locations of the two heat exchangers were conducted according to the elevated temperature design codes of the ASME-NH and RCC-MR and the evaluation results were compared.
