MHI and QST Complete Outer Vertical Target Prototype of the Divertor for the ITER in Southern France

Tokyo, July 31, 2024 - Mitsubishi Heavy Industries, Ltd. (MHI) and National Institutes for Quantum Science and Technology (QST), as part of the effort to manufacture components to be used in the ITER experimental fusion reactor(Note1),(Note2) under construction in southern France, have completed a prototype of the Outer Vertical Target (OVT) since the prototype manufacturing was started in June 2020. Here, the OVT is one of the key components of the Divertor. Last year, the high heat flux test on plasma facing units of the OVT was performed by the ITER Organization and heat removal performance was confirmed, and then, our manufacturing processes of the PFU were certified by the ITER Organization. MHI has now completed a prototype that will be a full-scale mock-up of the OVT and is ready for series production.
