CLADDING METHOD FOR THE FIRST WALL OF FUSION REACTOR

摘要

PURPOSE:To obtain a cladding method for the first wall of a fusion reactor in which the surface of the first wall SUS 316 material of the fusion reactor is cladded with a material having a high melting point and high thermal conductivity and the cladding is easily repairable in case of damage during a use. CONSTITUTION:On the surface opposite to plasma side of the first wall of a fusion reactor, a high melting point material having thermal expansivity close to that of diamond is welded or cladded. On the surface of the high melting point material, diamond is cladded by plasma jet of methan and hydrogen.
