Description
Chinese Fusion Engineering Testing Reactor (CFETR) is a superconducting magnet Tokamak, it has the equivalent scale with complementary function to International Thermonuclear Experimental Reactor (ITER). The vacuum vessel (VV) which has a double-layer structure，Cooling water circulating through the double-layer structure will remove the heat generated during operation. The VV will provides a high-vacuum environment for the plasma, improves radiation shielding and plasma stability, and provides support for in-vessel components.
The CFETR VV is composed of 16 sectors, the angle of each sectors is 22.5°. The Research and Development(R&D) of the key technologies to the VV manufacture have been carried out a few years ago by Institute of Plasma Physics Chinese Academy of Science(ASIPP), including Narrow-Gap welding, cutting and non-destructive testing (NDT) , Poloidal Segment(PS) and sector assembly technologies, etc. ASIPP is constructing a 1/8 sector real size VV now. The manufacture of the PS for first 1/32 sector VV have been completed in 2015, The PS will be assembled into a whole this year. This paper will describe the study of the assembly technology for the CFETR 1/32 Vacuum Vessel.
