Seismic response analysis and test of CHASNUPP steam generator lower part model

  • 1. Shanghai Nuclear Engineering Research and Design Inst. (China)

Description

The seismic response analysis and test of CHASNUPP steam generator lower part model has been performed. The lower part model consists of a tube sheet, 441 U-shaped rods (modeled on U-shaped tubes), 9 tie rods, a tube bundle wrapper, a lower shell and some position bolts between the lower shell and the wrapper. The analytical and experimental data show that the steam generator lower part model is more stiffer than pure tube bundle model. The movement of the lower part model appears in a systematic model in earthquake condition. The fundamental natural frequency of this model is higher than that of the tube bundle model and lower than that of the lower shell. The global frequency components are absolutely dominant and the local frequency components are insignificant. The experimental data are in good agreement with the results from finite element method. The effectiveness of mathematical model is verified
