Seismic isolation technique, which has been successfully applied for traditional buildings for many years, is an appealing option to render nuclear power plants a larger seismic margin from design earthquakes and standardize the seismic design procedure for different locations with various seismic fortification intensities. Considering the seismic demand from installed facilities and pipes within the plants, a three-dimensional base isolation technique is developed in this study. A simplified single-degree-of-freedom model was first used to search for the suitable parameters for the base isolation layer. It is found that the vertical frequency of the base-isolated plant shall be larger than 1.0 Hz to avoid the dominated rocking mode. Time history analyses were then conducted to further explore the damping effect of the base isolation layer on the structural response indices. It is observed that the damping within the reasonable range, commonly less than 30%, is helpful to suppress structural displacement, velocity and acceleration. Accordingly, laminated rubber bearings with thick rubber layers were designed by procedures for conventional rubber bearings. Thanks to the large thickness of rubber layers, the vertical frequency was significantly reduced to the acceptable level. Experimental examination reveals that the equation used to calculate the horizontal stiffness of thick rubber bearings is accurate, while the one for the vertical stiffness needs modification.
