Structural Analysis of the BCC Temporary Supports

The ITER magnet system consists of TF coil, PF coil, CS and CCs. The bottom correction coils are one set of ITER Correction Coils (CC), which is used to reduce the range of magnetic error fields created by the other coils. Before the BCCs are finally positioned, it needs to be temporarily supported in Pit. The design and analysis of BCC temporary supports need to be considered load combinations when BCCs are placing in the Pit. The FE analysis results meet the design requirements and stress evaluation criteria. An engineering calculation, like bolt joint, assuring the integrity of the analysis work. This work could provide a necessary reference for the manufacture of BCC Temporary Supports.
