As says Igor Rodin, the Deputy general director for thermonuclear and magnetic technologies of the NIIEFA JSC Science and Research center “Synthesis”, the shipment of the coil PF1 is a result of a joint effort of few teams who diligently designed the electromagnetic system of the tokamak for more than 20 years, engineered and launched serial production of super conductors and manufacture of the coil itself. “We passed through all the stages from development of the design documentation, qualification of processes and solution of the most complicated technological challenges to off-the-shelf tests that confirmed compliance with all ITER requirements. I consider this event as a definite achievement of the Russian science. For the Russian Federation this is the biggest electromagnet ever. There are few countries in this world capable to manufacture such a thing” - , said Igor Rodin.
The coil PF1 (diameter 9m, mass 200 tons) is one of the six poloidal field coils in magnetic system designed to maintain plasma inside the ITER reactor. The coil is a rather complicated element based on eight super conductive two-layer double-threaded waffles. This is one of 25 systems which the Russian Federation is in charge of, as set forth by the ITER project. The coil PF1 is attributed to the category of elements required to obtain the first plasma in the facility. The key technologies and facilities to generate the coil had been developed by the “NIIEFA” JSC (part of the State corporation “Rosatom”), the actual production took place at the Srednenevsky Shipbuilding Factory JSC.
The first out of eight double-threaded waffles was winded and qualified in 2016, the last one in 2019. In March 2021 the vacuum-induced saturation of the coil winding was completed, so has one of the most labor-consuming and critical production stages of the magnet. In march 2022 the Russian coil successfully passed through the acceptance test campaign prior to the shipment to the international organization ITER. As it was required by the ITER regulation conditioned by the highest priority of the coil PF1 and in order to obtain the first plasma inside the reactor, the item was subject to few checks in course of the factory acceptance test.
The agreement for manufacture and delivery of the coil PF1 between the Russian ITER agency and the ITER international organization was entered into in 2011. This was one of two poloidal field coils manufactured in member countries. The other four are assembled directly at construction site of the future facility due to their large dimensions.
