In this study, the investigation of the local damage evaluation method for the SC structure subjected to impact load was carried out. The conventional RC formula and SC formula to calculate wall thickness to prevent perforation were studied and compared. Finally, these results were compared with finite element analysis results using LS-Dyna, and the future direction to develop the reasonable local damage evaluation method of the NPP SC structure was suggested.
