Biography
Metallic materials expert – Framatome – I am a Materials Engineer graduated from the Ecole des Mines de Saint Etienne, France (double diploma “Ingénieur Civil des Mines” and Master of Science – 2008) and then from the University of British Columbia, Canada (PhD – 2012). I have developed a sheer interest in metallic materials from the early stages of my training as an engineer. This was triggered by a first internship at ArcelorMittal R&D center (Maizière-lès-Metz, France) where I was working on the design of new high strength steels for automotive application, and it continued on all the way up to the completion of my PhD work at UBC in 2012. I then took a position at Aperam Stainless Europe R&D center where I was responsible for the design and development of high strength stainless steels for automotive application (2012-2017). In 2017 I joined Framatome (then Areva NP) to work as a materials engineer on the ASTRID project (Gen IV reactor) at DTI and two years later (2019) I moved to the Fuel BU to take a position as a Component Owner for Nickel-based alloys. Since 2019, I work in the Design department of the Fuel BU (FDE-E) where I am responsible for the definition of technical specifications for the procurement of Ni-based alloys, and I’m also supporting the development of new components (for Fuel Assemblies and Control Rods) made by additive manufacturing (specification definition, industrialization ramp-up, qualification, R&D work).

31 ARQANE project – Towards a global approach for Additive Manufacturing (L-PBF) machine/process qualification for the nuclear industry
Additive Manufacturing (AM) of metallic components has gained considerable attention in the past few years in the nuclear industry. Indeed, the different AM technologies are versatile, allow for more complex and efficient designs and can lead to significant gains in the global manufacturing supply chain compared to conventional manufacturing routes. However, as AM processes are relatively new, one of the key challenges is to develop a robust machine/process qualification strategy before moving to serial production, especially for sensitive applications such as components for the nuclear industry. The ARQANE (Actions de Réalisation et de Qualification en Additif pour le Nucléaire) project was set up and defined to tackle this particular issue. In this paper, a common machine/process qualification methodology is described, from sample printing to material testing and characterization. The developed methodology was applied to qualify five (5) L-PBF machines of different dimensions and brands commonly used in the industry, using 316L powder batches originating from two different suppliers. Subsequent material testing and characterization revealed that impact toughness, tensile and microstructural properties were in reasonable agreement between the different L-PBF machines, except for one machine which yielded lower values, this being due to a lack of precise control of the gas flow withing the chamber during manufacturing. The resulting material properties were found to be slightly dependent on powder batch, this being particularly highlighted by impact toughness results. Powder batch 1 showed average impact energy of 136 J vs. 158 J in average for powder batch 2, a difference which could be explained by the different microstructures induced by those two batches. Nevertheless, those values are still acceptable for nuclear applications. Overall, the work performed in the ARQANE project on machine/process qualification represents a significant progress for the nuclear industry, opening wide perspectives for the development and implementation of components additively manufactured with the L-PBF technique.
