The invention provides a marine right-angle edge-covered reactor cabin corner shielding structure and a ship, the shielding structure is arranged in a frame-type grillwork of a reactor cabin, the shielding structure is a square structure which is formed by layered and partitioned layer-by-layer splicing, and the shielding structure comprises a shielding body, a thin steel plate, angle steel and a cladding steel plate. The shielding structure is tightly attached to the wall of a reactor cabin and laid outwards layer by layer, and the shielding body sequentially comprises a first shielding material, a second shielding material, a third shielding material and a fourth shielding material from inside to outside. The outer side of the shielding body is coated and fixed with a thin steel plate, and is welded and fixed with a group of angle steel; a covering steel plate is laid on the outer side of the reactor cabin structure and used for sealing the installation grids and protecting shielding materials in the reactor cabin. According to the technical scheme, the problems of shielding integrity and light weight of the arc-shaped corner part of the reactor cabin 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直角包边型堆舱角隅屏蔽结构及船舶,设置于反应堆舱的框架式格架内,屏蔽结构为分层分块的逐层拼装而成的方形结构,包括:屏蔽体、薄钢板、角钢和覆面钢板。屏蔽结构紧贴堆舱舱壁逐层向外敷设,屏蔽体,由里向外依次包括:第一屏蔽材料、第二屏蔽材料、第三屏蔽材料和第四屏蔽材料;屏蔽体的外侧包覆固定一层薄钢板,并焊接固定一组角钢;在堆舱结构的外侧敷设覆面钢板,用于安装方格的密封,保护堆舱内部的屏蔽材料。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圆弧形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。
