Among the eighteen upper ports of the ITER Tokamak, the upper ports #4, #5, #6 and #7 are located in the Neutral Beam (NB) cell. A roughing filter and an upper port plug are located inside each upper port. Vacuum Vessel (VV) in-service inspection and neutron flux monitor ports are located on the balcony area near the third Heating Neutral Beam (HNB). This paper describes the concept design of the Upper Port Remote Handling Equipment (UPRHE) that provides means to maintain the components at the upper ports and the balcony area within the NB cell. The UPRHE can move along the toroidal direction to access the upper ports and can deploy various remote handling (RH) tools into the upper ports to access the components that require maintenance. The UPRHE consists of permanent installations in the NB cell and removable equipment that is transferred from the Hot Cell Facility to the NB cell only when carrying out the maintenance activities. The permanent equipment is the cabling device mounted on wall. The removable equipments are the upper port trolley, manipulator transporter, end-effectors, manipulators, and other RH tools. The concept design and the RH compatibility assessment demonstrate that the proposed UPRHE can perform the identified tasks and is ready to move on to the next design phase.

在 ITER 托卡马克的 18 个上部端口中，上部端口 #4、#5、#6 和 #7 位于中性束 (NB) 单元中。粗滤器和上端口塞位于每个上端口内。真空容器 (VV) 在役检查和中子通量监测端口位于第三加热中性束 (HNB) 附近的阳台区域。本文描述了上端口远程处理设备 (UPRHE) 的概念设计，该设备提供了维护 NB 单元内上端口和阳台区域组件的方法。UPRHE可以沿着环形方向移动以访问上端口，并且可以将各种远程处理（RH）工具部署到上端口以访问需要维护的组件。UPRHE 由 NB 单元中的永久装置和仅在执行维护活动时从热单元设施转移到 NB 单元的可移动设备组成。永久性设备是安装在墙上的布线设备。可拆卸设备有上端口小车、机械手运输车、末端执行器、机械手和其他RH工具。概念设计和 RH 兼容性评估表明，提议的 UPRHE 可以执行确定的任务，并已准备好进入下一个设计阶段。
