Preparation to manufacturing of ITER plasma facing components in Russia

The preparation of the procurement activities for the ITER plasma-facing-components (PFC) is currently well underway. Three ITER procurement packages associated with PFCs are currently allocated to the Russian Federation (RF): delivery of the central assembly of the divertor (dome and reflector plates assemblies), delivery of 40% of the first-wall (FW) panels and high heat flux testing of divertor components during the qualification and subsequent manufacturing phases. The results of the qualification process for these tasks undertaken by RF industry are presented. Qualification mockups of the dome divertor structure were successfully manufactured in accordance with the ITER specifications and tested at heat fluxes exceeding operational ones. The maturity and reliability of the proposed design and manufacturing technologies, proposed by RF industry, was therefore demonstrated. To confirm the manufacturing readiness of technologies proposed for the fabrication of the ITER first wall, three qualification mockups were fabricated. Two were heat flux tested in two facilities abroad. In addition to launching the qualification process, the PFC team at Efremov Institute is preparing the industrial facilities for serial production of above mentioned components. A brief description of such facilities is presented in this paper, together with the manufacturing technologies to be used. Two electron beam facilities (Tsefey and IDTF) for various high heat flux testing of PFC components are also described.
