英文摘要	The China Fusion Engineering Test Reactor (CFETR) tritium plant has to deal with a larger amount of tritium than ITER. The tritium source term is one of the key issues for safety assessment and operation of the CFETR. In this paper, the preliminary estimation and safety analysis of the tritium source term for the CFETR tritium plant in normal operation have been performed on compliance with the ongoing plant design. The estimation method adopted is the system dynamics simulation performed by the Tritium Analysis program for fusion System developed by the Frontier Development of Science (FDS) team. The preliminary analysis results show that the storage and delivery system still stores the most amount of tritium. Until after 1 month of operation the plasma-facing material needs to be cleaned in the CFETR corresponding to the 600-g limit. Tritium losses, such as tritium permeation into the coolant and release to building rooms, are of a much smaller amount than tritium decay in the 2-week operation. It is worth noting that the tritium concentration somewhere in the tritium plant can be slightly more than 1 DAC (derived air concentration). These preliminary analysis results could provide some valuable references for the safety design and tritium management of the CFETR tritium plant.
