Sofia Carnevali obtained her Double Master Degree in Nuclear and Energy Engineering from the University of Pisa and the ENEN in 2009. Her final internship was on SMRs design and scaling analyses at Westinghouse Nuclear (USA). She got her PhD in 2013 at CEA with a thesis on the fast dynamics and exothermic reaction between sodium and water for the ASTRID project (SFR). She joined CEA CATHARE team in 2013. She contributes to the physical modelling and validation of the code. She is the CEA technical referent for the ATLAS and PKL/OECD Projects since 2014 and for the ACME/OECD Project since its launch (2019). She was in charge of the 3D-module for Reactor Pressure Vessel (RPV) applications and its validation over integral facilities. She investigates the feasibility of the code application to some particular new configurations, i.e. the In Vessel Retention (IVR) design, suggesting some modelling improvements. At present, she also works on the modelling and the validation of CATHARE code for passive safety systems in collaboration with EDF and FRAMATOME. She also contributes to the modelling of the stratification criterion in CATHARE code. Part of her activity is focused on the scaling studies.
