Title of the thesis:Analysis of the thermonuclear reactor magnetic circuit considering the use of high-temperature suerconductors
Summary:The aim of this thesis is research of current REBCO high temperature superconductors utilization in fusion reactor toroidal field coils system.Nuclear fusion has potential to join to fourth-generation reactors in the future as a stable source of higly concentrated energy. To meet these ambitions, a number of technical issues need to be solved. One of these issues is the generation of high magnetic fields by toroidal coils as a part of the reactor containment. Required magnetic fields are only possible to reach using superconductors. High temperature superconductors are capable of achieving higher magnetic fields at liquid helium temperatures, which can significantly contribute to increasing plasma stability, its density or temperature depending on the design.The work is based on current concept of the European DEMO fusion reactor. The first part provides theoretical basics of fusion and plasma physics. Next part is devoted to theory of high temperature superconductors. The end of theoretical part briefly outline function of the fusion reactor. Practical part begins by simulating of simplified toroidal coil of the fusion reactor. Based on these results system with the use of high temperature superconductors in CORC cable is proposed. In the following experimental part, high temperature superconductors produced by commercial manufacturer are chosen and its characterisation is performed. At the end of the work a simplified sample of proposed fusion reactor cable is made, which is subsequently subjected to measurements of the influence of mechanical deformation and magnetic field on the electrical properties or the cable.
