This paper surveys the results of 10 years of experiments with the Tore Supra ergodic divertor. It stresses the qualities of the divertor in terms of particle screening and edge radiation efficiency, while maintaining core confinement. The balance of assets and drawbacks with a conventional X point divertor is an essential criterion of its usefulness. An assessment of its possible implementation in a next step device can then be sketched. The rather high poloidal mode number and the neutron shield requirement are shown not to prevent implementation in a reactor size tokamak.
