At JET high radiaton, high power discharges were achieved by neon seeding. The increasing radiation causes these discharges to transit from ELMy H-mode into a regime with degraded pedestal profiles, an X-point radiator, and detached divertor targets. The confinement time is not affected by the increased radiation. Depending on the heating power, the plasma transits into L-mode, M-mode, or ELM-free H-mode. These heating power dependent modes and the stability of the discharges will be investigated in this presentation.
