  • Seismic performance of the dehydrogenation fan for nuclear power plants was evaluated based on the shaking table test of earthquake simulation.Dynamic characteristics including the orthogonal tri-axial fundamental frequencies and equivalent damping ratios were measured by the white noise scanning method.Artificial seismic waves were generated corresponding to the floor acceleration response spectra for nuclear power plants.Furthermore,five OBE and one SSE shaking table tests for dehydrogenation fan were performed by using the artificial seismic waves as the seismic inputs along the orthogonal axis simultaneity.Operating function of dehydrogenation fan was monitored and observed during all seismic tests,and performance indexes of dehydrogenation fan were compared before and after seismic tests.The results show that the structural integrity and operating function of the dehydrogenation fan are perfect during all seismic tests;and the performance indexes of the dehydrogenation fan can remain consistent before and after seismic tests;the seismic performance of the dehydrogenation fan can satisfy relevant technical requirements.
