Serge Bellet (mechanical engineering, INSA Lyon, 1983) started his career in EDF in collaboration with the 1300 MW PWR unit building. He was in charge of the reactor coolant primary circuit (with Framatome) including the vessel and its internals. Since 1987, He had been working in the Basic Design Department (Equipment Division), responsible for RPV internals.
He was in charge of the French RPV Internals lifetime, for the current units, and also of the new design of the future European series of reactor (EPR). During this period the job was mainly focused on materials behavior, irradiation damage, rupture mechanism and particularly on Lower Internals bolts and Inconnel pins. Contracting some studies with Westinghouse Pittsburgh.
Since 1997, he moves towards Thermal Hydraulics analysis in the vessel, working on several projects concerning PWR vessel flows. He’s also involved in the industrial validation of a new thermal hydraulics code, built by the National Hydraulics Laboratory in EDF. His background includes PWR operations, transient analysis and primary loops behavior in asymmetric conditions.
In 2006, he moves on Physics Reactor / Thermalhydraulics division of Septen (Basic design department of EDF in Villeurbanne close to Lyon).
He is a technical animator of CFD team. He works on code validation, safety studies for the all 58 units of EDF, EPR FA3, and have in charge to build a methodology for using CFD in the safety analysis : He starts a work about uncertainties on CFD, and CFD methods for a good quality of results. In touch with French safety Authorities and also several international partners, NRG, FZDR; OECD/NEA/CSNI/GAMA, and is the EDF representative for the PWROG ASC (Analysis Subcommittee) since 2008.
He's also a teacher in different French engineer schools (INSA; ECL; EC Pekin, INPG) on reactor operating process, safety notions, nuclear materials failure assessment, GEN IV nuclear reactor,…
