In the 2011 off the Pacific coast of Tohoku Earthquake, several NPPs observed nonlinear response of buildings due to the large earthquake. In order to improve component fragility evaluation, enhancement based on the lessons learned from recent knowledge and technique is required. Currently in Japan, seismic response analysis regarding buildings has been conducted by using a nonlinear lumped mass model. The building response analysis result provides a probability density function of the seismic floor response in the installation position of the component based on the time history seismic response analysis for each seismic level evaluated. In this study, a novel fragility method was developed. The lognormal distribution curve of seismic response of the component provides a combination of the floor response spectra in the component natural period and component response factor which includes logarithmic standard deviations. The presented method can be expected to provide a realistic and reasonable solution to obtain the fragility curve of components in NPPs.
