FIRST WALL OF NUCLEAR FUSION DEVICE AND METHOD FOR MANUFACTURING SAME

PROBLEM TO BE SOLVED: To provide a first wall of a nuclear fusion device which makes it possible to enhance the bonding strength of a surface material and a basement and to improve the constructibility of the device and a method for manufacturing the first wall of the nuclear fusion device. SOLUTION: The first wall of the nuclear fusion device which has the basement 30 with a cooling means 40 and the surface material 10 bonded to the basement 30 opposite to plasma is characterized in that the first wall is provided with a coating material 50 for forming an oxide film 51 by coating the bonded face of the basement 30 and a ceramic-base bonding material 20 for bonding the surface material 10 to the basement 30 through the agency of the oxide film 51. Consequently, the first wall of the nuclear fusion device which makes it possible to enhance the bonding strength of the surface material 10 and the basement 30 and to improve the constructibility of the device and a method for manufacturing the first wall of the nuclear fusion device can be provided.
