Graphene, a remarkable material with exceptional properties, has been at the forefront of extensive scientific research in the past two decades, leading to a vast array of proposed applications. The material's structural strength, superior thermal and electrical conductivity, anti-corrosion properties, and versatile sensor capabilities has made it an exceedingly desirable option for various functions in the nuclear industry. However, despite the increasing interest in graphene's potential uses in the nuclear industry, a comprehensive and detailed review of its possible applications in this context is still missing. This article endeavors to bridge this gap by presenting a thorough analysis of the potential applications of graphene in the nuclear industry. Specifically, its applications to pre-reactor treatments, fuel enrichment, heavy water preparation, filtration, radionuclide waste conditioning, monitoring through sensors, augmented heat transfer and corrosion prevention. These areas offer numerous opportunities for graphene-based materials to enhance the efficiency, safety, and reliability of nuclear power plants. This article not only illuminates the exciting opportunities of graphene usage in the nuclear field but also serves as a valuable resource for researchers, policymakers and stakeholders seeking to leverage the unique properties of graphene to drive innovation and advancement in the nuclear industry.

“…6 Multiple layers improve the interaction of X-ray radiation with MWCNT, leading to a higher scattering of the radiation and faster energy attenuation. 7 Moreover, the MWCNT speeds up the dispersion of X-rays due to its reduced weight. Furthermore, the impregnation of heavy metals such as zinc, cerium, bismuth, americium, gadolinium, iron, thallium, or their salts in MWCNTs can improve the shielding effectiveness of these hybrid nanostructures.…”

“…In contrast, graphene-based materials now play a crucial role in the development of novel radiation attenuation materials. Graphene's intense electric conductivity, saturation velocity, exceptional mechanical strength, and optical characteristics make it a potential material for high-performance shielding (Birk and Frank, 2017;Verma et al, 2022). Graphenecontaining porous borate-based bioactive glass scaffolds were previously fabricated by the polymer foam replication approach to use in bone tissue engineering applications (Turk and Deliormanlı, 2017).…”

Introduction: Graphene-based materials have gained increasing attention for use in radiation attenuation applications. In this study, pristine graphene nanoplatelet-containing (1, 3, 5, and 10 wt%) borate-based bioactive glass composites were prepared.Methods: Structural properties, Vickers microhardness, and gamma-ray radiation shielding properties of the fabricated composites were examined in detail.Results and Discussion: Results revealed that the inclusion of the graphene in the glass matrix led to a decrease in the bulk density of the glass-based composites from 2.41 to 2.31 g/cm3. Similarly, a decrease in Vickers hardness was obtained as the graphene concentration was increased due to a convoluted effect of the non-uniform distribution of graphene nanoplatelets in the bioactive glass matrix and the higher residual porosity. Vickers hardness of the bare and the 10 wt% graphene-containing bioactive glass discs were measured to be 5.03 ± 0.28 GPa and 1.87 ± 0.56 GPa, respectively. On the other hand, the incorporation of graphene starting from 3 wt% decreased the crack propagation after indentation which may be attributed to an increase in fracture toughness. In the study, fundamental gamma ray absorption properties of graphene-containing bioactive glasses were examined in the 0.015–15 MeV incident photon energy range. For this purpose, the Py-MLBUF code was employed to determine gamma ray absorption parameters. Results showed that linear attenuation coefficients of the glass-based composites decreased due to a decrease in the density of the samples. On the other hand, as graphene was incorporated into the bioactive glass structure, exposure buildup factor and energy absorption buildup factor values increased. The growing graphene ratio in the glass structure contributed negatively to the photon’s tendency to interact with the material.
