Abstract The ITER Test Blanket Module (TBM) Program has significantly evolved since 2018. The number of equatorial ports allocated for operating the Test Blanket Systems (TBSs) has been reduced from three to two. As consequence, four TBSs can be simultaneously installed and operated, versus six previously. Since the dedicated space in the various rooms of the Tokamak Complex has been kept unchanged, the existing space constraints have been substantially relaxed. The paper addresses the possible selection of the four TBSs for the initial configuration and design of the involved TBMs and the main on-going R&D carried out by the ITER Members (IMs) in support of the TBS designs. It describes also the main progress of the design of the infrastructures needed for hosting the four TBSs (e.g., port plugs, port cell common components, common maintenance tools and equipment). The design of the TBS Connection Pipes (CPs) System has reached its final phase since, being captive, it needs to be installed before the First Plasma.

摘要 自 2018 年以来，ITER 测试毯模块 (TBM) 计划有了显着发展。分配给运行测试毯系统 (TBS) 的赤道端口数量已从三个减少到两个。因此，可以同时安装和操作四个 TBS，而以前是六个。由于托卡马克综合体各个房间的专用空间保持不变，现有的空间限制已大大放松。本文讨论了可能为所涉及的 TBM 的初始配置和设计选择四个 TBS，以及 ITER 成员 (IM) 为支持 TBS 设计而进行的主要持续研发。它还描述了托管四个 TBS 所需的基础设施设计的主要进展（例如，端口插头、端口单元公共组件、常用的维护工具和设备）。TBS 连接管 (CPs) 系统的设计已进入最后阶段，因为它被俘获，需要在第一等离子之前安装。
