Variation of reliability-based seismic analysis of an electrical cabinet in different NPP location for Korean Peninsula

Tahmina Tasnim Nahar et al.

Summary: This study investigates the variation of seismic response of electrical cabinets in different locations in a nuclear power plant through classical reliability analysis. The study selects seismic ground motion based on probabilistic seismic hazard analysis and evaluates reliability using two different methods. The study models the cabinet and verifies the results through experiments, providing a comparison of seismic reliability assessment variation.
