Mitigation of the earthquake loads by seismic isolation technology is very promising for enhanced safety and economy of the next generation nuclear power plant. A research for 3D seismic isolation technology has been conducted under the sponsorship of the Ministry of Economy, Trade and Industry. Two types of 3D seismic isolation systems were developed. One is the 3D entire building base isolation system. The other is the vertical isolation system for main components in the horizontally entire building base isolation. For the former technology, the "rolling seal type air spring + hydraulic rocking suppression system" is selected alter several studies. In this study, the reduced models of the 3D seismic base isolation system was tested on the shake tables. The test results show that this system satisfy the reliability of seismic isolation function and is applicable to the actual plant.
