Mitigation of earthquake loads by seismic isolation technology is very promising for enhanced safety and economy of the next generation nuclear reactors. A research project has been undertaken for the development of 3D seismic isolation technology, under the sponsorship of the Ministry of Economy, Trade and Industry. There are two types of 3D seismic isolation system concept. One is the 3D entire building base isolation technology and another is the vertical isolation device for main component with horizontally entire building base isolation technology. For the former technology, three types of system concept were nominated. These are "Hydraulic 3D base isolation system", "Independent cable reinforced rolling-seal air spring" and "Rolling seal type air spring". This paper reports the performance requirements for 3D isolation system and the criteria for the system selection.
