| Abstract: | EAST is an advanced super-conducting Tokamak experiment device for the study of fusion around the world. The cryogenic system, which is one of the key subsystems of EAST, has the responsibility for the cooling of the toroidal field coils, poloidal field coils, case, thermal shield and current leads. It should be assured that the cryogenic system has the capability to run continuously. In this paper, the fault tree analysis method was used to the evaluation of the cryogenic system's reliability. The fault trees of the cryogenic system were constructed and calculated using the self-developed software RiskA. The failure rate of this system and the importance of the components have been obtained. Some advice has also been proposed, which could be used to optimize the design and improve the reliability. |
