Abstract. Compact plate heat exchangers (CPHE) are made of millimetric grooved plates stacked and joined together. Among joining processes, diffusion welding is the only one that allows joining the core of the modules without filler material (e.g., braze). However, several challenges must be met to achieve such components, including management of deformation of channels, soundness of joints, non destructive controllability and so on. Part of the achievements made in the frame of the development of the sodium-gas heat exchanger modules of the ASTRID prototype of 4th generation nuclear reactors are described in this presentation, focusing on process modeling and experimental validation with 316L steel.
