Study on Assessment Method for Typical Plate and Shell-Support in Nuclear Power Plants

The work of shock test of the support-model including model design,layout of the sensor,the test method and process,experimental results and discussion is presented in this paper.The experimental and the numerical results show that the nominal elastic stresses are much higher than those stipulated in the existing shock assessment codes of supports,which are supposed to be conservative.This preliminary study will provide some experimental and numerical data for modifying the present shock assessment criterions of supports.
