Quench simulation of the CFETR Central Solenoid Model Coil

The Central Solenoid Model Coil (CSMC) has been manufactured as part of the R&D projects for the China Fusion Engineering Test Reactor (CFETR), and it will undergo testing in the second half of 2024. For the safety operation of magnet, predictive analyses are required to study thermal-hydraulic behavior of the CSMC during the quench. In this paper, the different quench initial position is detailed studied, for example, quench initiates at the peak magnetic field region and the lowest magnetic field region. In addition, the different quench disturbances are considered, such as (disturber length 0.01 m and disturber time 3 ms), (disturber length 1 m and disturber time 3 ms), and (disturber length 6 m and disturber time 100 ms). In all cases, the designed quench protection system is satisfied with the present design criteria concerning the hot spot temperature and the maximum helium pressure.
