The first vacuum port for ITER has been assembled and is ready for welding
German company «MAN Diesel & Turbo» tailor-made for the ITER the first branch pipe for the vacuum chamber of the International Thermonuclear Experimental Reactor. According to the ITER press service, the branch pipe was delivered to South Korea in early December, 2017. There it will be welded to the corresponding segment of the vacuum chamber at the Hyundai plant.
In Russia, a part of the international project is the JSC «NIIEFA of. D.V. Efremov» enterprise, which is located in St. Petersburg. This is one of the key enterprises of the nuclear industry, which in Soviet times was the main developer of equipment for basic research in nuclear physics, high-energy physics, and controlled thermonuclear fusion. Today, the enterprise manufactures the vacuum chamber upper branch pipes of the thermonuclear reactor with a height of 4.6 meters and a mass of 23.5 tons by order of the Project Center ITER.
Russia will supply an international project with 18 branch pipes, which are intended for diagnostics, heating equipment, pumping devices and provide penetration inside the vacuum chamber. Besides, branch pipes are the first safety barrier and classified as equipment operating with radioactive materials under pressure, according to the Project Center ITER.
«It is difficult to overestimate the importance of the beginning of welding our port to the first manufactured sector of the future reactor body. The vacuum chamber is the basis of the installation, and I am satisfied that we, together with our Korean colleagues, are successfully coping with our responsibilities for creating it», Anatoly Krasilnikov, the ITER director told.
It is known, that installation work of the first branch pipe will be completed by the end of next year. The second will come to Korea by the beginning of 2018.
The upper branch pipes are high-tech products, the manufacture of which is a real challenge for engineers and production workers, ITER specialists told reactor.space.
This is not the entire country’s contribution to the international project. In total, the share of the Russian Federation in ITER financing is about 1/11 of its overall cost, which is still estimated at 19 billion euros. The timing of ITER launch is scheduled for 2025.
