Divertor filtering element for a tokamak nuclear fusion reactor; divertor employing the filtering element; and tokamak nuclear fusion reactor employing the divertor

Abstract From the Canadian patent

A divertor for a TOKAMAK nuclear fusion reactor having at least one target , element (44 49, 66) for intercepting the path (G) of contaminating particles 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).
