This presentation serves as an introductory welcome from EDF to the 2023 FLUG Meeting, where EDF presented the application of FLACS-Hydrogen in their hydrogen risk analysis activities for nuclear power plants.
About the speaker
Namane Mechitoua (EDF)
Namane Méchitoua is an esteemed member of the R&D Division at Électricité de France (EDF), where he applies his expertise in computational fluid dynamics (CFD) to enhance nuclear safety applications. His notable work includes significant contributions to the NEPTUNE project, a collaborative R&D initiative dedicated to advancing nuclear reactor simulation tools, with a particular focus on two-phase flow thermal-hydraulics. Méchitoua’s scholarly publications, which delve into hydrogen distribution simulations and two-phase flow modelling, reflect his pivotal role in developing and validating multi-fluid codes for nuclear reactor safety. His efforts contribute to EDF’s commitment to leading-edge safety and innovation in the energy sector.
Sebastien Martin-Barbaz (EDF)
Sebastien Martin-Barbaz is an engineer in Mathematical and Mechanical Modelling at EDF, specialising in Fluid Mechanics and Energetics. His current focus is on the safety aspects of nuclear energy, as he completes an advanced master’s degree in Nuclear Safety at Arts Et Métiers Paristech (ENSAM). His expertise encompasses computational fluid dynamics (CFD), with skills in various programming languages and software such as FORTRAN, C++, Python, Ansys Fluent, and FLACS. He has been instrumental at EDF’s SEPTEN in studying the consequences of hydrogen explosions within nuclear power plants, specifically for the 900 MW reactors’ fourth decennial inspection, analysing risk areas, and modelling dispersion and explosions
