The location of the Poloidal Field (PF) coils inside the Toroidal Field (TF) coils in tokamak fusion reactors is highly desirable to minimize the cyclic loading and associated heat loads due to ac losses in TF coils. Fusion devices of this configuration built to date have not emphasized coil and coil structure design of fabrication features which facilitate replacement of the PF coils in the event of a failure during operation. This means excessive machine downtime and high costs which make this approach to future machines appear very unattractive. However, based on studies on PLT and TFTR this paper discusses some of the problems involved with replacement of normal copper coils located inside TF coils, as well as suggested design alternates. This may be helpful in the design of tokamak reactors with similar coil configuration.
