The invention provides a high-safety casting molding ship reactor bottom shielding structure and a ship, the reactor bottom shielding structure is arranged in a double-layer bottom structure below a reactor, and the reactor bottom shielding structure comprises a template, a shielding body, a sprue gate and an exhaust port. The template is a steel plate and is connected to a double-layer bottom structure below a reactor, a sprue gate and an exhaust port are reserved in the template, and a cavity enclosed by the template and the double-layer bottom structure is a container required for pouring a shielding material; the shielding body is a cured material of a shielding material, and the shielding material is injected into a container required for pouring the shielding material through the pouring port and the exhaust port. According to the technical scheme, the reactor bottom shield is arranged in the double-layer bottom, scattering of neutrons and gamma rays at the bottom of the reactor to an adjacent area is weakened to the maximum extent, and radiation safety of personnel and equipment in the adjacent area is protected. Meanwhile, the radiation level of the hull plate below the reactor is reduced, the hull plate is protected against radiation paint, and the hull structure is prevented from being corroded beyond design.
本发明提供一种高安全性的浇注成型船用堆底屏蔽结构及船舶,堆底屏蔽结构设置于反应堆下方的双层底结构内,包括:模板、屏蔽体、浇注口和排气口。模板为钢板,连接于反应堆下方的双层底结构,模板预留浇注口和排气口,模板与双层底结构围成的空腔,即为浇注屏蔽材料所需的容器;屏蔽体为屏蔽材料的固化物,屏蔽材料经浇注口和排气口注入所述浇注屏蔽材料所需的容器。本发明技术方案,在双层底中设置堆底屏蔽,最大限度减弱反应堆底部中子、伽马射线向邻近区域的散射,保护邻近区域人员、设备辐射安全。同时,降低反应堆下方船体外板辐射水平,保护船体外板耐辐照油漆,避免船体结构出现超设计的腐蚀。
