Abstract

The design and research work for the China Fusion Engineering Test Reactor (CFETR) started from 2012. Remote handling (RH) is one of the most important ways for maintenance of CFETR Blanket. The RH is composed of two manipulators, auxiliary manipulator is used for cooling water pipe cutting and welding, while main manipulator is design to carry heavy components such as blanket through the upper port relying on positioning accuracy and reliability. This paper presents how the main manipulator can be more precision to optimize the safety of RH tasks. The paper also discusses an effective way to optimize the design and analysis of the main manipulator. The results show that the optimization of the water hydraulic manipulator makes a significant contribution to the R&D of the RH of CFETR.
