Tritium Dynamic Transport Analysis for CFETR Helium Cooled Ceramic Breeder Blanket and Auxiliary System

To promise tritium self-sufficiency and ensure tritium safety is one of the main objectives of CFETR. The tritium behavior in system should be analyzed in detail, including dynamic changes of tritium retention, tritium release, and tritium concentrations, for the design of CFETR helium cooled ceramic breeder blanket and its auxiliary system. In this work, an integrated dynamic tritium transport analysis tool TriSim-Dynamic is used to analyze the tritium dynamic transport in CFETR helium cooled ceramic breeder blanket and its auxiliary system. The results, including the tritium concentration and partial pressure in coolant and purge gas, the tritium inventory in the wall of pipes and structural materials, the dynamics of tritium flux for permeating into vacuum vessel, water-cooling systems and buildings by way of the structure materials or the walls of pipes in auxiliary system. The steady state results are compared with the steady tritium analysis tool TriSim-SA to verify the analysis results. The results can be a reference data for tritium safety analysis in CFETR.
