China’s nuclear power plants were built in coastal areas. High wind such as hurricane would make nuclear power plant transmission lines, structure and component to fail, leading to the transient or loss of off-site power accidents, which have an impact on the safety of nuclear power plants. This paper focuses on high wind hazards analysis of the operational nuclear power plants. We study the high wind probability safety assessment methods and the main technical elements. The following five tasks were performed to complete the high wind PSA models: Site Specific High wind hazard analysis, High wind Walk-downs and equipment list screen out, High wind Fragility Analysis, Integrate High wind Impacts into PSA Model, and Risk Quantification of High wind PSA Model. The methodology can be used to addresses high wind hazard probability risk analysis of nuclear power plant.
