The Promise of Tritium Catalyzed Deuterium Tokamaks^a

The promise of the tritium catalyzed deuterium (TCD) fuel cycle for power-generating or fuel-producing tokamaks is assessed. If ignitable, TCD power reactors can be significantly more economical than Cat-D reactors; the higher the fraction of the ³He recovered from the plasma, the more economical the TCD reactor can be. The fissile fuel production ability of TCD fusion breeders can be double that of D-T fusion breeders.
