Abstract

Abstract

Containment structure is one of the most important structures in nuclear power plant, and its seismic fragility is the focus of probabilistic seismic safety assessment of nuclear power plant structure. Combined with nonlinear finite element analysis technology and incremental dynamic analysis method, the fragility of nuclear power plant containment under near-site vibration is analyzed. In addition, in order to overcome the limitations of the traditional global damage index of containment structure based on top displacement, an energy based global damage index is proposed and its effectiveness is verified. Finally, a fragility curve construction method considering the statistical uncertainty of seismic fragility parameters is proposed. The research results show that the global damage index of the containment structure proposed in this paper can reflect the overall deformation characteristics of the containment structure well, and its variability is smaller than that of the global damage index based on top displacement. The overall impact of statistical uncertainty on the corresponding fragility curve of containment structure under different damage performance levels can be ignored, but it has a certain impact on the lower tail of the fragility curve.
