Current Progress of Tritium Fuel Cycle Technology for CFETR

Tritium fuel cycle technology is crucial for the successful development of China fusion engineering test reactor (CFETR) which aims to bridge the gap between a fusion experimental reactor (ITER) and a demonstration reactor. One of the major missions of CFETR is to realize tritium fuel self-sufficiency with a tritium breeding ratio over 1.0. In order to attain tritium self-sufficiency as well as ensure safe handling of tritium, it is important to establish a closed tritium fuel cycle. Therefore, a tritium plant which consists of various tritium processing systems and tritium safety systems is indispensable for the successful operation of CFETR. Since the mid-2000s, when China joined the ITER project, a series of R&D activities on tritium fuel cycle technology have been carried out. The current progress in terms of conceptual design of tritium plant, development of sub-system technologies and tritium related materials is presented in this paper.
