The invention belongs to the field of ship design, and particularly relates to a nuclear power icebreaker containment energy absorption buffering protection structure which is applied to ice load resistance of a nuclear power icebreaker. Comprising an anti-impact area, a transition area and a reactor cabin, the anti-impact area is connected with the transition area, the transition area is connected with the reactor cabin, and the transition area is located between the anti-impact area and the reactor cabin. The system and the method have the beneficial effects that 1) the containment is better protected by arranging the additional isolation cabin and an accessory structure thereof outside the containment; (2) by arranging the supporting longitudinal girders, the stress distribution of impact loads transmitted to components in the ship is improved, and the position of a high-stress area is benign changed; and (3) the structure has the characteristics obviously weaker than those of an anti-impact area and a reactor cabin component, and meanwhile, a large number of open pores are designed, so that an obvious buffer area and a fracture interface are formed in the area after a ship is impacted by an extreme event, and the integrity of the reactor cabin containment is effectively protected.
本发明属于船舶设计领域,具体涉及一种核动力破冰船安全壳吸能缓冲保护结构,应用于核动力破冰船的抗冰载。包括3个区域分别为抗冲击区,过渡区和反应堆舱,所述的抗冲击区连接过渡区,过渡区连接反应堆舱,过渡区位于抗冲击区与反应堆舱之间。本发明的有益效果在于:1)本发明在安全壳外通过设置额外的隔离舱及其附属结构更好地对安全壳进行了保护;2)本发明通过设置支撑纵桁改善了冲击载荷向船中构件传递的应力分布,使高应力区位置发生了良性改变;3)本具有明显弱于抗冲击区和反应堆舱构件的特点,同时设计了大量的开孔,使当船舶遭受极端事件冲击后,在该区域形成明显的缓冲区和断裂界面,有效保护了反应堆舱安全壳的完整性。
