Abstract

As solution to the problems of transient and steady state energy exhaust the type-III ELMy H-mode is proposed. In recent experiments at JET it has been demonstrated that with seeding of nitrogen a radiative power fraction of 95% can be achieved, reducing the steady state and transient heat flux to acceptable values. Though the confinement of these discharges is reduced as well. Nevertheless, the ITER operational domain for Q = 10 does foresee operation at confinement enhancement factors of H_98(y,2) ≈ 0.78 at higher plasma currents (I_p = 17 MA). It has been demonstrated at JET that an integrated scenario with type-III ELMs is feasible.
