ABSTRACT
This paper presents the framework for the application of seismic isolation system (SIS) to nuclear power plants (NPP) considering life-cycle of the NPP, cost-benefit induced by SIS application, and inspection for the damaged SISs. In this proposed framework, the effect of the SIS application on the life-cycle cost (LCC) analysis of NPP, which lead to formulation of cost-benefit of the SIS application, is investigated. The approach for cost-benefit analysis integrates the probability of earthquake occurrence during the service life, time-dependent seismic fragility of NPP, and interaction between structural performance reduction after earthquake and the required cost to improve the structural performance. Furthermore, a probabilistic approach for efficient inspection of SIS with potential damage is presented.
