Fully non-inductive discharges are performed on the Tore Supra tokamak using Lower Hybrib (LH) waves in a current drive scheme. The MHD aspect is a crucial issue for these discharges, since after hitting an MHD limit it may run into a regime where a strong permanent MHD activity develops. This so-called MHD regime degrades fast electron confinement as well as LHCD efficiency and electron confinement in the plasma core. In the 2003 campaign, a milestone has been reached with the injection of more than 1 GJ of energy in the tokamak, in stationary discharges lasting more than 6 minutes. But the MHD regime as been encountered in several discharges, while the record discharges have shown a very stationary MHD activity in the plasma core without triggering the MHD regime.
