This paper gives the results of the probabilistic analysis of the seismic resistance of nuclear power plant (NPP) structures. The seismic probabilistic safety assessment based on the requirements of the agency IAEA and US NRC are presented. On the base of the geophysical and seismological monitoring of locality the peak ground acceleration and the spectrum of the acceleration was defined for the return period 104 years. There is showed summary of calculation models and calculation methods for the probability analysis of the structural safety considering load, material and model uncertainties. The numerical simulations were realized in the system ANSYS. The results from the safety analysis of the NPP structures with reactor VVER440 are presented.
