摘要

After the Fukushima nuclear accident last year, the efforts have actively been made to enhance the safety of the nuclear power plant (NPP). As a part of these efforts, applying the seismic isolation system to NPP structures is being considered and researched seriously in several countries. In Korea, the related research is also on the way by the public utilities for the recently developed Korean NPP. Accordingly, Korea Institute of Nuclear Safety (KINS) is conducting an independent research project to provide regulatory rules on the seismic isolation system for NPP structures. In this paper, identified regulatory safety issues relating to approval of the seismic isolation system and the isolated NPP structure are summarized. The possible safety issues include the design, analysis, manufacture, performance evaluation, installation, maintenance, and replacement of the seismic isolation system itself and the isolated NPP structure. The issues have been identified based upon experience, research information and documentation available to date.
