The ITER fusion reactor (https://www.iter.org/) is a scientific-technical experiment, being built in the south of France. Its aim is the demonstration of the technical feasibility of controlled nuclear fusion for energy production. The international partners who are taking part in the construction of the device are the European Union, the United States, China, Russia, Korea, Japan and India. The executive responsibility is with the ITER International Organization (ITER IO), under the auspices and direction of the ministerial level ITER Council.
The ITER is a tokamak-type fusion device, where the proper diagnostics of the 100-million-degree-Celsius plasma is a task of utmost importance. One of the important subsystem of plasma diagnostics systems is the special electrical infrastructure that serve them. Since in the ITER’s vacuum chamber, where the plasma is generated, very unique physical conditions exist (neutron/gamma radiation, thermomechanical and electromagnetic loads, etc.), the subsystems that serve the plasma diagnostic systems have to comply with extraordinary requirements, naturally along with the requirements dictated by the diagnostic experiment itself.
In the diagnostic racks of the equatorial ports as well as in the remotely serviced lower ports, the fixing of the electrical cables is not at all resolved, and as such requires one-off development, one-off design, testing and manufacturing. The aim of the present project is the R&D of the special clamping mechanisms that hold the running cables.
