Application of resistive magnet tokamaks to fissile fuel production has been studied. The Resistive magnet Tokamak Fusion Breeder (RTFB) uses semi-monolithic Bitter plate toroidal field coils and has a major radius of 3.81 m. with a fusion power output of 618 MWth. An energy-multiplying blanket gives a total blanket power of 4986 MWth, while producing 3742 kg/yr of 233U and 239Pu. The RTFB cost is estimated to be $2.6B.
