A feasibility study on the seismic design of nuclear reactor buildings with application of a seismic isolation systemis introduced. After the Hyogo-ken Nanbu earthquake in Japan of 1995, seismic isolation technologies have been widelyemployed for commercial buildings. Having become a mature technology, seismic isolation systems can be applied toNPP facilities in areas of high seismicity. Two reactor buildings are discussed, representing the PWR and BWR buildingsin Japan, and the application of seismic isolation systems is discussed. The isolation system employing rubber bearingswith a lead plug positioned (LRB) is examined. Through a series of seismic response analyses using the so-named standarddesign earthquake motions covering the design basis earthquake motions obtained for NPP sites in Japan, the responsesof the seismic isolated reactor buildings are evaluated. It is revealed that for the building structures examined herein: (1)the responses of both isolated buildings and isolating LRBs fulfill the specified design criteria; (2) the responses obtainedfor the isolating LRBs first reach the ultimate condition when intensity of motion is 2.0 to 2.5 times as large as that of thedesign-basis; and (3) the responses of isolated reactor building fall below the range of the prescribed criteria.
