The invention provides a light-weight layered stacking ship reactor bottom shielding structure and a ship, the light-weight layered stacking ship reactor bottom shielding structure is arranged in a double-layer bottom structure below a reactor, the shielding structure is arranged by means of a frame type double-layer bottom structure, and the shielding structure comprises a shielding body, a thin steel plate and angle steel. The reactor bottom shielding structure is a polygonal structure approximate to a circle when viewed from a plane, and the polygonal structure is arranged between the body outer contour of the reactor and the primary shielding outer contour; the reactor bottom shielding structure, the primary shielding structure and seawater below the ship body form a complete shielding system; the shielding bodies are of a plate structure and are stacked in a layered mode from bottom to top, and thin steel plates are welded on the outer sides of the shielding bodies and are welded and fixed through angle steel. According to the technical scheme, the problem that the radiation field of the adjacent area of the reactor severely exceeds the standard due to back scattering of neutrons and gamma rays at the bottom of the reactor in a nuclear power ship and a nuclear power floating platform to the adjacent area through ship bottom seawater and a double-layer bottom can be solved.
本发明提供一种轻量化的分层堆叠船用堆底屏蔽结构及船舶,设置于反应堆下方的双层底结构内,屏蔽结构依托框架式双层底结构进行设置,包括:屏蔽体、薄钢板和角钢。堆底屏蔽结构从平面上看为逼近圆形的多边形结构,多边形结构介于反应堆的本体外轮廓和一次屏蔽外轮廓之间;堆底屏蔽结构与一次屏蔽、船体下方海水形成完整的屏蔽体系;屏蔽体为板材结构,屏蔽体自下而上的分层堆叠,在屏蔽体的外侧,焊接薄钢板,并使用角钢焊接固定。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底部中子、伽马射线经船底海水及双层底向邻近区域的反散射,导致反应堆邻近区域辐射场严重超标问题。
