Nuclear power plant (NPP) structures face significant challenges in ensuring structural resilience subjected to earthquake motions. The inerter-based vibration absorbers (IVAs) have been proven control vibration, but they not applied small modular reactor (SMR) structures. In this study, the optimal IVA parameters are investigated for SMR structures, which focus on reducing seismic response of first floor and fifth floor. By using a genetic algorithm (GA), IVAs optimized minimize storey displacement variance acceleration variance. Besides, robustness analysis is performed ensure practical. various ground motions selected time history (THA) illustrate equipped with IVAs. results THA demonstrate that enhance performance compared traditional positioning IVAs, mitigation both achieved. This study explores deeper understanding IVAs' efficacy beneficial practical use
