The invention provides a multilateral fold line type reactor cabin corner shielding structure for a ship and the ship, which are arranged in a frame type grillwork of an arc corner of a reactor cabin and comprise a filling material, a shielding material A, fixed steel bars, a shielding material B, a shielding material C, angle steel and a cladding steel plate. In the frame type structure of the circular arc corner of the reactor cabin, the shielding structures are laid outwards layer by layer in a manner of clinging to the wall of the reactor cabin; filling materials filled in a special shape are arranged in the shielding inner layer, and the arc-shaped shielding structure in the frame-type structure is optimized into a multi-section broken line type shielding structure; and the fixing strip steel is used for welding and fixing after the shielding material A is laid, and the unoccupied part of the layer is filled and leveled up with the shielding material B. According to the technical scheme, the problems of shielding integrity and light weight of the reactor cabin corner part in a nuclear power ship and a nuclear power floating platform can be solved, leakage of reactor radiation to the peripheral area is weakened to the maximum extent, and the radiation safety of personnel and equipment in the peripheral area is guaranteed.

    本发明提供一种船用多边折线型堆舱角隅屏蔽结构及船舶,设置于反应堆舱圆弧形角隅的框架式格架内,包括:填充材料、屏蔽材料A、固定条钢、屏蔽材料B、屏蔽材料C、角钢和覆面钢板。在反应堆舱圆弧形角隅的框架式结构内,屏蔽结构紧贴堆舱舱壁逐层向外敷设;在屏蔽内层设置异形填充的填充材料,将框架式结构内的圆弧型屏蔽结构优化为多段折线型屏蔽结构;固定条钢,用于所述屏蔽材料A敷设完成后的焊接固定,此层空余部分使用屏蔽材料B填平。本发明技术方案,能够解决核动力船舶、核动力浮动平台中反应堆舱角隅部位屏蔽完整性与轻量化问题,最大限度地减弱反应堆辐射向周边区域的泄漏,保证周边区域人员、设备辐射安全。
