Three-Level Assessment of the Safety of Floating Nuclear Power Plants Under Hazard Waves

In comparison to land-based nuclear facilities, floating nuclear power platforms situated at sea are frequently exposed to wave impacts, resulting in periodic oscillations of the platform. These oscillations have the potential to affect systems, equipment, and pipelines. Of greater concern are the more severe effects caused by high significant wave heights and the greater energy density of destructive waves, which directly impact the health and safety of the floating nuclear power station system. To address this, it is crucial to consider the impact of extreme ocean conditions caused by waves as a design basis accident, utilizing a deterministic evaluation approach. Therefore, this paper presents a three-level framework for analyzing the hazards of waves in the context of floating nuclear power platforms. It systematically evaluates the impact of wave hazards by considering three key aspects: statistical analysis of wave intensity and frequency in the sea area, hydrodynamic simulation of the floating nuclear power station, and assessment of system safety.
