Abstract Scope |
Additive manufacturing (AM) is a booming technology that offers new perspectives for industry. In the nuclear industry, Molten Salt Reactors are developing fast and AM can be useful in designing and producing different parts for those reactors. Harsh conditions are expected for the components, including irradiation and molten salt corrosion. The characteristics of AM materials under these conditions must be investigated to ensure acceptable performance. In this study, superalloys (Hastelloy X, Inconel 718, ABD-900AM) and 316L steel were manufactured with laser power bed fusion (LPBF). The microstructural characterizations have shown a good quality of manufacture and a Fe5+ ion irradiation campaign was carried out at 550 °C in the JANNuS installation (CEA Saclay). The purpose of this irradiation was to obtain high dose (>100 dpa) to study the swelling under irradiation. Thanks to the characterizations carried out by Transmission Electron Microscopy, the behavior under irradiation of the alloys is discussed. |
