A major upgrade of the Tore Supra heat and particle exhaust capability, known as the CIEL project and installed during the year 2000 shutdown, will raise the heat exhaust capability to 25 MW (convected and radiated) steady-state, and the pumping capability to ~4 Fa.m{3}/s, and will allow Tore Supra to investigate high power steady-state plasma operation, with target discharges up to 25MW-1000s. Consequently an upgrade of the wave based heating and current drive system is studied (ICRH, LHCD, ECRH/CD), in order to reach this target, in terms of input power and current drive capability, but also in terms of current and pressure profile control, in order to address relevant "advanced tokamak" physics, including steady-state discharges balancing LHCD and bootstrap current, and possibly exhibiting internal transport barriers. The optimisation of antennas for such high power long pulse operation is also discussed.
