Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a seismic load suppression device for reducing the seismic input to a reactor and reactor internal parts including fuel. SOLUTION: This device includes a plurality of earthquake isolation devices 28 positioned in circumferential direction between a reactor stage 14 and a lower stage 20, and a plurality of displacement limiters 30 connected to the foot 22 of the lower stage 20 and positioned adjacent to the reactor stage 14. The earthquake isolation devices 28 includes a plurality of layers contacting elastic materials 40 and steel plates 42 by turns. Each displacement limiter 30 includes a cantilever 44. The beam 44 includes a beam core 46 and two steel plates 48 and 50 piled on the outer surface facing to the beam core 46. The steel plate 42 made of carbon steel with smaller yield strength than the beam core 46.
