Abstract:

According to the system design and arrangement of helium cooling system of China helium cooled ceramic breeder (CHCCB), helium cooling system simulation model is built using large one-dimension fluid simulation software Flowmaster. For different operation conditions of tritium breeding blanket system, helium flow conditions and parameter distribution are simulated for helium cooling system, using such simulation model. Temperature, pressure and velocity distributions and other related parameters have been obtained on different scenarios for hot waiting state, hot standby state, normal operation state and tritium out-gassing state, which provide reference for the design of system and equipment selection. Meanwhile, the model and simulation results have some reference significances for the simulation of helium cooling system for CFETR.

Key words: Helium cooling system, CHCCB-TBS, CFETR, Flowmaster

摘要：
