The optimized external current drive sources, self-generated non-inductive bootstrap current and plasma core stability properties provide a good prospect of achieving a high fusion gain at reduced plasma current for long durations in ITER. One of the remaining issues is the erosion of the divertor target plates associated with the type I ELM regime. A possible solution could be to operate with a plasma edge in the type III ELM regime (reduced transient and stationary heat loads) obtained with impurity seeding. An integrated hybrid type III ELM regime with a normalized pressure beta(N) = 2.6 (PNBI similar to 20-22 MW) and a thermal confinement factor of H-98* 98(y, 2) similar to 0.83 has been recently successfully developed on JET with nitrogen seeding. This scenario shows good plasma edge condition (compatible with the future ITER-like wall on JET) and moderate MHD activity. In this paper, we report on the experimental development of the scenario (with plasma current I-p = 1.7MA and magnetic field B-t = 1.7T) and the trade-off between heat load reduction at the target plates and global confinement due to nitrogen seeding and type III ELM working conditions.</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">ISI:000260311700012</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 364BRTimes Cited: 0Cited Reference Count: 42</style></notes><custom1><style face="normal" font="default" size="100%">Fusion Physics</style></custom1><auth-address><style face="normal" font="default" size="100%">[Corre, Y.; Joffrin, E.; Monier-Garbet, P.; Arnoux, G.; Hacquin, S.; Imbeaux, F.; Litaudon, X.; Loarer, T.] CEA, IRFM, F-13108 St Paul Les Durance, France.
