❖ General context: NAAREA is a French company founded in 2020, positioning itself as an innovative player in the energy sector. It is developing a fourth-generation nuclear reactor technology called XAMR (eXtrasmall Advanced Modular Reactor).

⮚ I played an essential role in the development and design of the forced convection loop. By collaborating closely with the Materials group departments, the electronics team, calculation engineers, as well as the valve and boilermaking teams, I contributed to the advancement of the loop's overall architecture.

❖ Project subject: Within the design and conception team, responsible for the study and modeling of various parts.

❖ Responsibilities held: Design Engineer

⮚ Work performed:

Overall salt loop architecture

o Creation of 3 custom frames for the loop

o Study and proposal of a sample pot concept

o Design of molten salt pipes in a forced convection loop

Modeling of heat exchangers

o Design and 3D modeling of plate heat exchangers using CATIA 3DEXPERIENCE

o The inlet and outlet orifice geometries were adapted according to the technical data provided by the calculation team, to ensure optimal compatibility with the system's hydraulic and thermal constraints.

o The overall geometry was optimized to be compatible with the constraints of available 3D printers, taking into account the limitations of additive manufacturing.

Creation of system piping

o Design and modeling of piping interconnecting the circuit components (valves, exchangers, pumps), considering space, flow rate, and maintenance constraints.

o Design and creation of system piping in accordance with ASME standards.
