This patent describes a tokamak reactor having a toroidal field coil assembly enclosing a generally toroidal shaped region having a toroidal axis. The toroidal field coil assembly comprises generally flat-washer shaped magnetic coils having generally flat opposing radial faces with respect to the toroidal axis. A cooling arrangement distributes coolant in the toroidal field coil assembly. The cooling arrangement comprises for each coil: (a) coolant channels for flowing coolant in the same direction through an interior of the coil, the coolant channels embedded within the coil and having inlets and outlets opening on a face of the coil, (b) the inlet and outlet openings disposed adjacent opposite ends of the coil and arranged radially along the coil face with respect to the toroidal axis, (c) a single inlet header formed in part by the soil face containing the inlet openings and in part by a curved supply conduit having a longitudinal opening along the length thereof, (d) a single outlet header formed in part by the coil face containing the outlet openings and in part by a curved return conduit having a longitudinal opening along the length thereof, and (e) the supply and return conduits each having longitudinal edges along their longitudinal openings, the edges being secured to respective portions of the coil face containing the inlet and outlet openings, such as by welding or brazing.
