A key issue for steady-state tokamak operation is to determine the edge conditions that are compatible both with good core confinement and with the power handling and plasma exhaust capabilities of the Plasma Facing Components (PFCs) and divertor systems. A quantitative response to this open question will provide a robust scientific basis for reliable extrapolation of present regimes to an ITER compatible steady-state scenario. In this context, the JET programme addressing steady-state operation is focused on the development of highly noninductive, high confinement plasmas with the constraints imposed by the PFCs. A new beryllium main chamber wall and tungsten divertor together with an upgrade of the heating/fuelling capability are currently in preparation at JET. Operation at higher power with this ITER-like wall will impose new constraints on non-inductive scenarios. Recent experiments have focused on the preparation for this new phase of JET operation. In this paper, progress in the development of Advanced Tokamak (AT) scenarios at JET is reviewed keeping this long-term objective in mind. The approach has consisted of addressing various critical issues separately during the 2006-2007 campaigns with a view to full scenario integration when the JET upgrades are complete. Regimes with Internal Transport Barriers (ITBs) have been developed at q95~5 and high triangularity, d (relevant to the ITER steadystate demonstration) by applying more than 30MW of additional heating power reaching βN~2 at Bo~3.1T. Operating at higher δ has allowed the edge pedestal and core densities to be increased pushing the ion temperature closer to that of the electrons. Although not yet fully integrated into a performance enhancing ITB scenario, Neon seeding has been successfully explored to increase the radiated power fraction (up to 60%), providing significant reduction of target tile power fluxes (and hence temperatures) and mitigation of Edge Localised Mode (ELM) activity. At reduced toroidal magnetic field strength, high βN regimes have been achieved and q-profile optimisation investigated for use in steady-state scenarios. Values of βN above the 'no-wall MagnetoHydroDynamic (MHD) limit'' (βN~3.0) have been sustained for a resistive time in high-d configurations (at 1.2MA/1.8T). In this scenario, ELM activity has been mitigated by applying magnetic perturbations using error field correction coils to provide ergodisation of the magnetic field at the plasma edge. In a highly shaped, quasidouble null X-point configuration, ITBs have been generated on the ion heat transport channel and combined with 'grassy' ELMs with ~30MW of applied heating power (at 1.2MA/2.7T, q95~7). Advanced algorithms and system identification procedures have been developed with a view to developing simultaneously temperature and q-profile control in real-time. These techniques have so far been applied to the control the q-profile evolution in JET advanced tokamak scenarios.
