Although different concepts for ITER TBMs have been proposed by other parties. However, the He-cooled solid breeder blanket （HCSB） with ferritic /martensitic steel （FMs） is still main stream for the fusion DEMO blanket design and has foundation of the world R＆D database. Therefore, a helium-cooled solid pebble bed concept has been adopted, as one of options, in Chinese TBM modules design. Under the cooperation of domestic institutes, the preliminary design and performances analysis as well as a draft design description document （DDD） based on the definition and the strategy of DEMO fusion reactor in China have been carried out recently.展开更多

It will demonstrate the integration of technologies for reactors and serve as a test facility for advanced components such as blankets. China has joined the program and will have her contribution to its construction, operation and so on. One of the in-vessel components fabricated by China is the shield blanket, which consists of first wall （FW） and shield blocks. FW is a joint of Be/Cu/SS, with Be as plasma facing material.展开更多

At the first stage of our research, high temperature HIP joining of Be/CuCrZr alloy was investigated by referencing their successful experience and Ti was selected as interlayer. Since the first wall will receive high heat flux during ITER operation, the heat load resistance capabilities, in particular thermal fatigue property is a crucial criterion of FW mock-ups. In order to test the heat load resistance capabilities of Be/CuCrZr joints, an electron beam heat load facility with beryllium handling capability has been constructed and heat removal performances and thermal cycling tests of Be/CuCrZr joints were carried out.展开更多
