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 technologies 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 after several studies. For the latter, the coned disk spring system is adopted. The reduced models of the two systems were tested on the shake tables. The test results show that the two systems satisfy the requirements of isolation and are applicable to the plant.
