Abstract:
There are described some alternatives to traditional technical solutions used in the designs of experimental Tokamak thermonuclear installations. The proposals must significantly reduce capital costs of the construction of toroidal field windings for thermonuclear power plants of this type. Cost reduction may be achieved by choosing a coil design that excludes degradation of the properties of a superconducting cable, significant simplifications of the cable design, cooling the winding with thermosyphon, avoiding the occurrence of high voltages due to using a quench back method for the winding protection, A procedure is described for the reliable selection of the operating current of the cable and the maximum permissible values of the electric field in it. It is considered also a facility of access to the thermonuclear unit of the power plant for routine service without dismantling the toroidal field winding and its vacuum shell.
