POLEMA supplied products for a thermonuclear reactor in France

Powder Metallurgy Plant POLEMA (part of the IMH) supplied about 5,000 bimetallic tungsten-copper plates for the International Experimental Thermonuclear Reactor ITER.

Bimetallic plates are to be used for thermal protection of a divertor, a device designed to maintain the purity of plasma in a tokamak. The plates are used in the central assembly of the divertor, the prototype of which was manufactured at NIIEFA (St. Petersburg) and shipped in December 2021 to France.

“Controlled thermonuclear fusion is the technology of the future. It is expected that the first industrial thermonuclear power plants won’t appear till the middle of the 21st century. Participation in such a project is a huge responsibility, but also an indicator of the technological capabilities of our enterprise. Shipment of another 10,000 plates for this project is planned for 2022,” Managing Director of POLEMA JSC Aleksei Filippov said.

The ITER (International thermonuclear experimental reactor) project to create an International Thermonuclear Experimental Reactor started in the 80s. XX century. The construction of the facility began in 2010. In addition to Russia, the United States, China, the European Union, India, South Korea and Japan participate in this project. The purpose of the project is to prove the possibility of commercial use of the fusion reaction.
