Description
The purpose of the Upending Tool (UT) is to upend the vacuum vessel (VV) 40-degree sectors and the toroidal field coils (TFC) from horizontal delivery orientations to vertical assembly orientations. According to the ITER assembly procedure, this upending operation is carried out by four hooks of the tokamak crane. And the VV and TFC which are upended with UT are transfer from the UT to sector sub-assembly tool (SSAT) for sector sub-assembly. For this reason, the UT is classified as a lifting accessory in the ITER load specification of PBS22.
This paper describes the UT design and upending sequence by crane with its components (VV and TFC) and presents the analysis results performed for the final design to verify the structural integrity of UT. The analysis cases for this verification are composed of the horizontal supporting on the floor, horizontal lifting (0°), 30° tilting, 45° tilting, 60° tilting, vertical lifting (90°), and vertical supporting on the floor. And, in this analysis, the mass and inertial moment of the components (VV and TFC) are reflected into point masses.
