摘要： Shielding (2) and exhaust (4) covers mountable on the primary manways of a nuclear steam generator for protecting maintenance personnel from potentially harmful radiation. Each of these covers (42, 44, 4) includes mounting flanges (8) which are detachably mountable to the manway flange. These mounting flanges (8) include brackets for mounting a dual rail track assembly (28) which in turn slidably mounts two opposing quarter circle panels (42, 44) which, when slid together, form a semicircular shielding cover (2). The shielding (2) and exhaust (4) covers of the invention may be easily mounted over their respective manways by a single person, and may be opened or closed by a single person standing to the side of the manway and hence out of the radiation shine emanating therefrom. Finally, the shielding material (46) contained in each of the covers (2, 4) is hermetically sealed within stainless aluminum sheet metal, which renders it mechanically strong and easily decontaminated.

摘要翻译：屏蔽（2）和排气（4）可安装在核蒸汽发生器的主通道上，用于保护维护人员免受潜在的有害辐射。这些盖（42,44,4）中的每一个包括可拆卸地安装到人造路缘的安装凸缘（8）。这些安装凸缘（8）包括用于安装双轨道轨道组件（28）的支架，该双轨轨道组件（28）又可滑动地安装两个相对的四分之一圆形面板（42,44），当它们一起滑动时形成半圆形屏蔽盖（2）。本发明的屏蔽（2）和排气（4）盖可以容易地由单个人安装在它们各自的工作台上，并且可以由站在人行道一侧的单个人打开或关闭，因此不在辐射发出光芒。最后，包含在每个盖子（2,4）中的屏蔽材料（46）被气密地密封在不锈钢金属片材内，使其机械地坚固并容易地去污。
