Feasibility of SMES devices based on the developed technology of superconducting magnets for tokamak fusion reactors

Recent achievements in the technology of superconducting magnets for the to kamak fusion devices Contribute to the applicability of GJ-range SMES for t he utilities by means of using already developed; components and constructe d production lines. The paper presents the technologies developed by the NI IEFA, VNIIKP and VNIINM, institutes, covering most of the critical items ne eded to construct the GJ-range SMES devices for the utility needs. That inc ludes software packages for the supporting analysis and SMES optimization, heavy current CICC production lines with the length of pull-trough jacketin g tooling of up to 1 km, 30 kV 40 kA-range cryogenic current leads and 30 k V high-pressure insulating breaks for "cold" and "warm" helium communicatio ns, various types of heavy-current 30 kV range commutating equipment, inclu ding superconducting switches, and cryogenic test facilities for the accept ance tests of the produced conductors, current leads and insulation breaks.
