[en] The final objectives of this project are as follows; Development of the key techniques for the ITER blanket first wall - ITER blanket first wall design and developing related techniques - Blanket first wall qualification test and verification of manufacturing technology - Qualification of the bonding technique and development of the fabrication method for the ITER blanket first wall. We are technically surveying the ITER system design data, the insufficient part of ITER design, and required R and D items and so on. And we are developing the manufacturing process and joining technology for the ITER blanket to complete the procurement with qualified blankets system. To evaluate the soundness of manufacturing process, specimen and mock-up tests are being prepared. Finally, we can obtain the key technology of nuclear fusion reactor especially on the blanket design, joining and manufacturing technology through the present project and these technologies will help the construction of Korea fusion Demo reactor and the development of commercial nuclear fusion reactor in Korea
