Abstract

Abstract

In this paper, the impendence function of the containment structure of Nuclear Power Plants is calculated by two methods in different codes, and the difference between the two calculation methods for anti seismic characteristics of the structure of nuclear power plants is studied. The effects of each data for foundation on the results from two calculation methods are explored, under the effects of the different Shear Wave Velocity of surrounding rock, Poisson’s ration and Bulk Density of surrounding rock, and the exact different values between the two calculation methods is given. The study shows that the Shear Wave Velocity of surrounding rock is the key factor for the impendence function.
