The air cooler radiator is an important auxiliary equipment of standby diesel-generator unit in a nuclear power plant. It is a seismic category I equipment and must be qualified. Seismic qualification was conducted on an air cooler radiator in a nuclear power plant by combining analysis with test. The mechanical model, materials parameters, load conditions and calculation results for seismic analysis were introduced, and structural stress was evaluated according to RCC-M standard. The design of test sample, test contents and requirements and test results for seismic experiments were introduced. The rationality of calculating model and design of test sample were verified by analysis of calculating results and seismic test results. Qualification results show that seismic performance of the air cooler radiator satisfies the requirements of relevant standards. Qualification methods have some reference significance for the seismic qualification of large-scale equipments in a nuclear power plant.
