Three dimensional seismic isolation devices have been developed for the base isolation system of the Fast Breeder Reactor that is an advanced nuclear power buildings. The developed seismic isolation system consists of the hydraulic type vertical springs with rocking suppression mechanism and the laminated rubber bearings for horizontal direction. In this paper, it is reported the frictional characteristics on high hydraulic pressure condition from the experiments on the 1/2 size of real device and the results of the seismic simulation on the real size building with isolation-device that has those characteristics.

Piping in a nuclear power plant puts across each floor at the same building or between two buildings, and it has many supported points. Therefore, the piping should be as a model subjected to multiple inputs in seismic analysis, but there isn't almost knowledge concerned with analysis for multiple inputs. In this paper, the analysis by using TDOF model having two supported points, and the shaking test by using U-bend piping test piece having two supported points was performed to investigate response of piping subjected to multiple inputs. As a result, the possibility of response analysis for piping subjected to multiple inputs was confirmed.
