Abstract
EAST Articulated Inspection Arm (AIA) robot is being mutually developed by ASIPP and CEA-IRFM for remote handling maintenance. It will permit remote visual inspection and to pick up small fragments inside the EAST tokamak vacuum vessel during experiments. Considering storage and support for EAST AIA, a sealed cask system has been designed and manufactured, which can be connected to EAST device through a ϕ250 mm connection port with two flashboard valves. The system consists of a 10 m long vacuum vessel with a linear guide rail for storage, guiding and conditioning, two mobile wagons for support and some auxiliary systems for keeping suitable work conditions and measurement. Besides, a stainless steel shuttle has been developed to support AIA robot and assemble with the linear guide. It can push the robot into tokamak vessel and back to the storage cask with a gear-rack driving mechanism. This paper mainly presents the overall description of the system design and some obtained implementation progress.
