| 英文摘要 | Divertor is one of the most challenging plasma facing components (PFCs) for fusion reactors both from the design and fabrication technology point of view. In this work, the new flat-type W/Cu/CuCrZr mock-ups were fabricated using hot isostatic pressing (HIP) and optimized brazing techniques. High heat flux (HHF) tests of the mock-up were performed on a comprehensive experimental platform to assess the heat removal capability and thermal fatigue resistance. The results indicate that the mock-up successfully endured the cyclic absorbed heat flux at 20 MW m- 2 for 1000 cycles with an inlet pressure of 1 MPa, an inlet water temperature of 20 degrees C and a velocity of 6.88 m s-1. The peak temperature of the tungsten (W) surface reached 926 degrees C at the 1000th cycle, which is less than the recrystallization temperature. In addition, no substantial melting at the loaded W surfaces, no detachment of any W/Cu units and no occurrence of any 'hot spot' during thermal fatigue cycling were observed. These results indicate that HIP assisted brazing technique is a powerful method for fabricating PFCs employed in HHF tests, and the flat-type W/Cu/CuCrZr structure is very promising to be used to upgrade the lower divertor of Experimental Advanced Superconducting Tokamak(EAST) and manufacture the divertor for China Fusion Engineering Test Reactor(CFETR). |
