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

摘要

A divertor for a TOKAMAK nuclear fusion reactor, having at least one target element for intercepting the path of contaminating particles from a toroidal channel in which plasma is formed and confined; and at least one grille structure interposed between a catch region, for catching the contaminating particles, and the input of a plasma purifying device. The grille structure is fitted with a layered structure of threadlike felt material facing the catch region and through which flows a mixture of deuterium, tritium. helium and impurities flowing through the grille structure.
