The completion of the first ever floating nuclear plant, “Academic Lomonosov” provided a practical solution for energy supply in high latitudes. There may be ice floes in the sea at high latitudes, and if the floating nuclear plant collides with them, it may lead to damaged flooding, threatening the safety of operation. In this study, based on the Euler multiphase flow model combined with the discrete element theory, a numerical simulation method was proposed to simulate damaged flooding of a ship in the crushed ice area. This method was used to numerically simulate damaged flooding and the navigation resistance in the crushed ice area, and the simulation results were compared with the model test results to verify the accuracy of the simulation method. Taking the independently-designed ship-type nuclear power platform of a ship type as the research object, considering the randomness of the distribution of broken ice, the above method was used to simulate its damaged flooding in the crushed ice area. Finally, the influence of crushed ice flowing into the cabin on the flooding process and the impact load on the hull structure were analyzed. The research results can provide a reference for relevant research on the damage flooding process of ships sailing in ice regions.
