Comparative evaluation of existing concepts for a 10-tesla FED toroidal field coil
Abstract
The existing design concept options for FED toroidal field coils were studied. The various design concepts are: (1) forced flow cooled NbTi cabled conductor; (2) He-II bath cooled NbTi cabled conductor; and (3) He-I bath cooled Nb3Sn-NbTi hybrid with cabled conductor. These design concepts are valuated based upon their relative merits, including technological maturity, operational reliability, overall reactor compatability, maintainability, and cost. The normalization of each design concept to meet similar operational requirements was investigated. The critical issues in the TF coil design, including the structural role of the helium vessel, quench protection, accommodation of neutronic and eddy current heating, credible fault criteria, and the possibility of prototype coil demonstration are discussed. The consequences and implications of extending the peak field in the range from 8 to 10 tesla was also studied.
