A Primary Study of Base-Isolation Technology in NPP

摘要

Earthquake is one of the damage factors to nuclear plant Safety. This paper was about the research of Base-Isolation Method of NPP in China, financed by Nuclear Industry Science Funds of China. In the subject, PHI440Lead-Rubber Bearing was manufactured, its mechanical characteristics was tested and the quasi-static force-displacement curves were obtained. On the other hand, the effect of the containment base-isolated was analyzed and compared the seismic responses of containment with that non-isolated, the advantage of using base-isolation technology was qualitative presented.
