Probabilistic Seismic Assessment of Nuclear Power Plants

Description: 

The seismic performance of nuclear power plants is critical for the safety operation of nuclear infrastructure given the catastrophic consequence if reactors are damaged by earthquakes. The soil exhibits significant spatial variability, which has important impact on evaluating the seismic performance of nuclear power plants under earthquake hazard conditions. The paper aims to present a probabilistic scheme to evaluate the reliability of nuclear power plants considering soil spatial variability in the face of earthquake hazards using the random finite difference method. A 3D soil-foundation-structure numerical model will be established to evaluate the seismic performance of nuclear power plants. A case study is utilized to demonstrate the effectiveness of the proposed framework for the probabilistic seismic assessment of nuclear power plants under earthquake hazards. The results from this paper can provide useful insights for practitioners to evaluate the seismic risk of nuclear power plants and make an informed decision in the face of earthquake hazards.
