Abstract:

Thermal hydraulic analysis and design for the ITER shield block vacuum hot helium leakage detection equipment was done to get the best heating scheme, and the result implied that the heating process would not show any unpredictable structure damage, moreover, the shield block could be heated efficiently, and both the engineering requirement and the thermal stress of components technical requirement could be satisfied by means of changing inlet gas temperature in stages.
