Abstract
A project has been undertaken in japan to develop three-dimensional (3D) seismic isolation systems for advanced fast reactors application, under the sponsorship of the japanese government. within this program, 3D base isolation systems with pneumatic and/or hydraulic devices are developed. A vertical isolation system with coned dish springs is also developed for reactor components with combined use of horizontal base isolation. This paper depicts a whole picture of the project and describes the current status of the development efforts.
