Development of tritium dynamic transport analysis tool for tritium breeding blanket system using Modelica

摘要: Abstract Demonstration of the engineering feasibility tritium breeding, including generation, extraction, control and safety is one main objectives ITER Testing Blanket Module (TBM) Program. As TBM concepts, transport assessment China Helium Cooled Ceramic Breeder its ancillary systems (called test blanket system, TBS) absolutely vital to understand analyze dynamic behaviors in system detail according operation scenario. Considering requirements analysis for HCCB TBS, an integrated tool has been developed by simulation language “Modelica”. The multiple physics effects are considered tool, aspects impacting transport, simplified thermal-hydraulics considering only linear loss local fluid, 1-d thermal conduction solid, hydrogen isotope permeation solution recombination on solid surfaces, desorption from ceramic breeder etc. A model TBS modeled verify functions accuracy this tool. results, such as change concentration/partial pressure fluids, inventory solids, fluxes etc., have obtained, which preliminary verified at various comparing with analytical hand calculations.
