A divertor for a TOKAMAK nuclear fusion reactor, having at least one target element (44, 49, 66) for intercepting the path (G) of contaminating particle s from a toroidal channel (33) in which plasma is formed and confined (13, 15, 17); and at least one grille structure (60, 70) interposed between a catch region (ZR, 54, 56), for catching the contaminating particles, and the input of a plasma purifying device (79). The grille structure (60, 70) is fitted with a layered structure of threadlike felt material (90) facing the catch region (54, 56) and through which flows a mixture of deuterium, tritium, helium and impurities flowing through the grille structure (60, 70).
