| 英文摘要 | The massive molten salt-graphite interface produced by liquid infiltration or vapor penetration in a molten salt reactor suggests the importance of irradiation-induced mixing and diffusion. We employed He+ ion beam irradiation to simulate neutron irradiation-induced mixing of Na and K in graphite. The depth distributions of both Na and K were measured by RBS (Rutherford backscattering spectrometry) and XPS (X-ray photoelectron spectroscopy) depth profiling. Both the mixing rate and the diffusion rates of the Na and K mark layers in the graphite induced by the ion beam irradiation were calculated. The results indicate that the diffusion rates of Na and K in the graphite reflector and/or moderator were several hundred nanometers per dpa irradiation dose. This could induce a change in the properties and cohesion of graphite. |
