Efremov Institute of Electrophysical Apparatus (NIIEFA, part of Rosatom) and the Sredne-Nevsky Shipbuilding Plant have confirmed the strength of the shipping frame for the PF1 superconducting coil of the ITER fusion reactor. The frame is designed to send a coil weighing 160 tons to France. Concrete blocks with a total weight of 274 tons were used to test the strength of the frame. A key part of the process was controlled by representatives of the countries participating in the ITER project online. PF1 coil with a diameter of nine meters is one of the six coils of the poloidal field in the magnetic system, which serves to contain the plasma in the ITER reactor. In total, Russia will manufacture and supply 25 different systems for ITER.
