The invention provides an arc-shaped reactor cabin corner shielding structure for a ship and a ship, the arc-shaped reactor cabin corner shielding structure is arranged in a frame type grillwork of a reactor cabin, the shielding structure is an arc-shaped structure formed by splicing layered and partitioned arc-shaped plates layer by layer, the radius R of each layer of arc-shaped plates is gradually increased from inside to outside, and the radius R of each layer of arc-shaped plates is larger than the radius R of each layer of arc-shaped plates. Comprising a shielding material A, fixing strip steel, a shielding material B, a shielding material C, angle steel and a cladding steel plate. The fixing steel bars are 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. The angle steel is used for welding and fixing after laying of the shielding material C; the covering steel plates are laid on the outer side of the stacking cabin structure and used for sealing the installation grids. 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圆弧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圆弧形板逐层拼装而成的弧形结构,每层弧形板材的半径R由内向外逐渐增大,包括: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。固定条钢用于屏蔽材料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。角钢用于屏蔽材料C敷设完成后的焊接固定;覆面钢板敷设于堆舱结构的外侧,用于安装方格的密封。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。
