Supporting analysis of the ITER TBM Frame and Dummy TBM designs

•Heat Transfer Coefficient calculated with dedicated 3D CFD analysis.•EM analysis performed for simultaneous evaluation of the Lorentz and Maxwell forces.•Thermo-structural analysis performed to identify critical areas.•Structural assessments as per RCC-MR 2007 performed on critical areas.•Design improvements on Plasma facing areas are needed. The validation and testing of tritium breeding blankets concepts, which are relevant for a future commercial reactor, is one of the goals of the ITER project. To achieve these objectives, mock-ups of breeding blankets, called Test Blanket Modules (TBMs), are tested in three ITER equatorial ports. Each TBM and its associated shield form a TBM-Set that is mechanically attached to a steel Frame. A Frame and two TBM-Sets form a TBM port plug (TBM PP). In case a TBM-Set is not available, it can be replaced by a Dummy TBM, steel made only. Both the design and manufacture of TBM Frames and Dummy TBMs are fully under the responsibility of the ITER organization. This paper describes the summary of recent analysis activities to support the design of the TBM Frame and Dummy TBM, which is presently in the preliminary design phase.
