A nuclear power plant comprises various buildings, such as the reactor building, turbine building, and exhaust stack. Such buildings and structures must continue to fulfill their functional requirements in the event of earthquakes to ensure that the nuclear power plant remains safe. This chapter discusses the earthquake-resistant design of buildings and structures at nuclear power plants. First, the flow of the earthquake-resistant design based on dynamic response analysis is explained. Focusing on the reactor building, the eternal loads considered in the earthquake-resistant design and their combinations with the stationary load are explained. In addition, static and dynamic design approaches are described. Dynamic response models of the buildings and the foundation ground for earthquake-resistant design, where the effects of the soil-structure interaction are taken into consideration, are explained. Furthermore, a method of verifying the earthquake resistance of facilities employing shaking table tests is described.
