N2 - The HT-7U device is a large fully Superconducting TOKAMAK Experimental Facility which is a National Large Scientific Project in China. The large fusion experimental device is being fabricated in the Institute of Plasma Physics, Chinese Academy of Sciences. In order to check the stability, a thermo-hydraulic analysis on the HT-7U TF and PF superconducting magnets was carried out using finite element method with adding the artificial viscosity and refined mesh in the disturbance region. The external heating is assumed as uniformly distributed over the conductor cross-section. The stability margin and quench are calculated under the various disturbance scenarios. Several simulation scenarios are assumed such as the disturbance spectrum, mass flow rate of supercritical helium. In the paper, numerical analysis on stability margin and quench characteristics is presented.
