| Abstract Scope |
The diverse forms of carbon and their unique properties make carbon a remarkable element for nuclear materials. The re-emergence of nuclear energy has unveiled the development of new carbon-based materials that can withstand the extreme environments of nuclear reactors. Raman spectroscopy offers a fast, non-destructive approach to identify and characterize the damage of various carbon materials with minimal intrusion. This technique involves using a laser to induce inelastic Raman scattering of light, allowing for determining characteristic vibrational modes of carbon materials. This presentation outlines the essential procedures for utilizing Raman spectroscopy to characterize carbon-based materials used in the nuclear industry and their effects on irradiation. Four test case materials will be presented: nuclear graphite, glassy carbon, diamond, and carbon-carbon composites. Part of the presentation will focus on the various options for specimen preparation, analysis of irradiated specimens, and, lastly, the findings and open questions associated with Raman spectroscopy. |
