摘要

Abstract

China Fusion Engineering Test Reactor (CFETR) is China's self-designed and ongoing next-generation fusion reactor project. Tritium confinement systems in CFETR guarantee that the radiation level remains below the safety limit during tritium handling and operation in the fuel cycle system. Our tritium technology team is responsible for studying tritium transport behavior in the CFETR tritium safety confinement system of the National Key R&D Program of China launched in 2017, and we are conducting CFETR tritium plant safety analysis by using CFD software. In this paper, the tritium migration and removal behavior were studied under a postulated accident condition for the Tokamak Exhaust Processing (TEP) system of CFETR. The quantitative results of the transport behavior of tritium in the process room and glove box during the whole accident sequence (e.g., tritium release, alarm, isolation, and tritium removal) have been presented. The results support the detailed design and engineering demonstration-related research of CFETR tritium plant.
