In order to ensure the earthquake-resistant safety of NPPs and avoid major equipment damage and damage of nuclear leakage, an elasto-plastic response analysis of the nuclear containment vessel structure is required to evaluate its seismic performance under strong earthquakes. Taking the CNP1000 nuclear containment vessel structure as the research object, the finite element software ABAQUS is used to establish a three-dimensional finite element model. Based on the dynamic elasto-plastic analysis theory, the influence of different earthquake intensity on the seismic response of the structure is analyzed. Through the displacement response, acceleration response and stress distribution of the structure, the characteristics of the seismic performance of the containment vessel are analyzed to obtain the structural response rules and structural damage links. The results show: the structure has an amplification effect on the acceleration response, and the amplification effect becomes mo...
