ARIES-RS magnet systems

A conceptual design of toroidal and poloidal field systems for the ARIES-RS reactor study is presented in this paper. Means of designing the toroidal and poloidal field system for minimized size and cost, optimized structure and increased access for maintenance are presented in the paper. Supports of the out-of-plane TF loads that do not interfere with maintenance operation have been designed. Structural analyses of several cases that have the common feature of avoiding material in between the outer legs of the TF coil are presented in this paper. The implications on the structural amount of material required are investigated. Methods of handling failure conditions in the toroidal field coil due to unbalanced currents are studied. Optimization of the conductor in the poloidal and toroidal field systems is carried out. Implications of the use of very fine superconducting strands for conductor stability and minimization of co-wound normal-conducting material are evaluated. Implications of novel schemes for magnet protection such as internal dump, are described.
