Seismic Fragility Analysis is studied, then the basic fragility analysis variables and their quantification methods which are used to analyze and calculate the seismic fragility of the air heat exchanger of passive accident heat removal system for China Experiment Fast Rector (CEFR) are introduced. Next, the median response spectrum in NUREG0098 is used to calculate median response factors of both structure and equipment, and finite element analysis is used to determine the capacity factor for the equipment. Finally, the results show that the median seismic capacity of the air heat exchanger is 3.53g which has the inherent randomness about the median and the uncertainty in the median value, respectively, 0.36 and 0.47, and the high confidence low probabilistic failure (HCLPF) capacity is 0.9g, so the air heat exchanger has a better seismic capacity.
