Overview of recent Russian materials and technologies R&D activities related to ITER and DEMO constructions

Russian concept for a DEMO-S demonstration fusion power reactor

“…Pilot industrial production in Russia has proved that the fabrication of experimental DEMO-RF TBM for the ITER from this steel is technologically possible [21].…”

“…At the next conceptual design stage, we intend to use Fe-12Cr-2W-V-Ta (EK-181) low activation ferritic-martensitic steel [21]. This option is based on the extensive experience gained from using ferritic-martensitic 12% Cr steels, such as EP-450 and EP-900 in the BOR-60, BN-350 and BN-600 reactors.…”

Excitation functions of the natCr(p,x)44Ti, 56Fe(p,x)44Ti, natNi(p,x)44Ti and 93Nb(p,x)44Ti reactions at energies up to 2.6 GeV

“…Natural titanium is also considered as the basic component of the developing low-activated V-Ti-Cr alloys of structural materials for advanced fusion reactors, which should work effectively in conditions of high neutron fluxes and high temperature regimes. 44 Ti will be important component of the long-lived residual radioactivity of such materials that will transform in the dominated one after about 3 years of a cooling-down time [3,4]. This paper presents the study of the cumulative production cross-sections of 44 Nb have been determined.…”

Evolution of the nanocrystalline structure of Nb3Sn superconducting layers upon two-stage annealing of Nb/Cu-Sn composites alloyed with titanium

“…Over the last decade, composite superconductors based on the Nb 3 Sn compound have been actively employed for generating high fields in superconduct ing magnets of thermonuclear reactors, in particular, such as TOKAMAK 15 (Russia) and International Thermonuclear Experimental Reactor (ITER) (France) [1][2][3]. In spite of great successes in creating progressive technologies of industrial production of multifilamentary superconducting wires, further investigations are necessary to satisfy the ever growing demands to their service characteristics.…”
