As the seismic isolation device for a fast reactor plant, we have developed a horizontal seismic isolation device and a three-dimensional seismic isolation device. We carried out the seismic response analysis at the fast reactor plant with the horizontal seismic isolation devices or the three-dimensional seismic isolation devices. Those evaluation result is reported. This series are summarized. Furthermore, we introduce the future development program of the seismic isolation device.
