The ultimate state of structural alloys for superconducting electromagnetic system of thermonuclear reactor
The main problem for realization of nuclear fusion reaction is plasma confinement. At present, only the tokamak closed-loop system of toroidal type can ensure plasma confinement time required for the initiation of fusion. A thermonuclear reactor with a superconducting electromagnetic system is being...

| description | The main problem for realization of nuclear fusion reaction is plasma confinement. At present, only the tokamak closed-loop system of toroidal type can ensure plasma confinement time required for the initiation of fusion. A thermonuclear reactor with a superconducting electromagnetic system is being developed within the framework of an international project. The selection of structural materials for high-loaded elements of systems under consideration is complicated by the fact that applied metals should manifest only a slight sensitivity to the plasticizing effect of an electric current. The analysis of service conditions for the elements of a superconducting electromagnetic system of thermonuclear reactor is performed. Based on the study of the peculiarities of deformation and fracture of alloys subjected to an electric pulse current and cryogenic temperatures, criteria for the ultimate state of the materials are established and the methods for their determination are outlined. |
