There is increasing interest in the concept of an advanced fuel tokamak reactor at large toroidal current. The concept of a high current reactor would be enhanced if passive non-inductive methods of current drive could be found to supply a significant part of the total current. In this paper, current drive by asymmetric synchrotron radiation in high temperature inhomogeneous tokamaks is discussed and the global normalised efficiency as a function of the peak density and temperature and profile indices is obtained. The computation shows that synchrotron radiation in a hot reactor can drive a significant part of the total current to be used as a seed for bootstrap current.
