摘要: 船舶撞击是浮动核电站核动力装置设计中的重要外部事件，对其安全性存在重大影响。本文基于核动力商船的碰撞设计研究历史，建立了适用于船舶碰撞分析的数值模拟方法并与已有试验结果进行了对比验证，利用本方法对不同场景下补给船撞击ACP100S浮动核电站进行了仿真模拟，得到了船首撞击和舷侧撞击过程中浮动核电站关键设备处的冲击响应。计算分析结果表明，舷侧撞击过程关键设备的加速度响应大于核动力商船的设计基准载荷1g。本文研究对浮动核电站船体以及反应堆关键设备的抗冲击设计具有一定的指导意义。Abstract: Ship collision is a significant external event for the design of nuclear floating facilities, and it has a great impact on safety. In this paper, based on the crashworthy design review of nuclear merchant ships, the numerical simulation techniques suitable for the ship-collision analysis are established and validated by the available experimental result in the literature. Using the validated numerical method, the collision between a supply ship and the ACP100S floating nuclear power plant (FNPP) is simulated for bow- and broadside-collision scenarios, and the shock response of the key shipboard equipment is obtained. The calculation and analysis results show that the shock acceleration of the key equipment in the broadside-collision case exceeds 1g, which is the design basis load for nuclear merchant ships. The research results of this study have certain guiding significance for the shock resistance design of floating nuclear power plant hull and reactor key equipment.
