The invention provides a large hatch cover of a spent fuel transport ship, and belongs to the technical field of ships. According to the large hatch cover of the spent fuel transport ship, each hatch cover is divided into at least two split hatch covers, two anti-radiation shielding layers are arranged inside and at the bottom of each split hatch cover, and two shielding layers need to be arranged at the joint of every two split hatch covers besides conventional weather tightness. Compared with the prior art, the cabin cover has the beneficial effects that as the anti-radiation shielding layer is arranged on the large cabin cover, on the premise that the weather tightness of the cabin cover is not reduced, the cabin cover also has good shielding performance so as to prevent radiation generated by radiation substances in the cabin from penetrating through the cabin cover to threaten external sailors, and the cabin cover is safer, more reliable, simple in structure and convenient to use. The manufacture and installation are convenient, and the purpose of the invention is effectively achieved.
本发明提供一种乏燃料运输船大舱盖,本发明属于船舶技术领域。本发明的乏燃料运输船大舱盖,每个舱分为至少两块的分体舱盖,所述每个分体舱盖内部和底部设有防辐射的两道屏蔽层,在每两个分体舱盖连接处除做到常规风雨密外,还需要同样设置两道屏蔽层。与现有技术相比,本发明有益效果:由于在大舱盖上设有防辐射的屏蔽层,在不降低舱盖的风雨密性的前提下,舱盖还具有良好的屏蔽性能,以防止舱内的辐射物产生的辐射穿透舱盖而对外部船员造成威胁,更加安全可靠,并且结构简单,制造及安装方便,有效实现本发明的目的。
