Modelling Steam Generators for Sodium Fast Reactor with Modelica

Abstract

EDF is involved with CEA and AREVA in a common effort for the development of the future nuclear reactor generations. The studies, currently performed by the partners, concentrate on the design of Sodium Fast Reactor types that may include different kinds of innovative circuits and components as compared to the SPX (Super PheniX) plant design. Based on previous knowledge on SG developed at EDF, with Sodium as hot fluid, and with the help of more recent methods of modeling using the Modelica libraries, a new model for the simulation of steam generator has been developed in order to help the designers of the heat exchangers to meet the requirements for a Sodium Fast Reactor plant design. The paper will present the current status of the model and a comparison of the results with those of the actual SuperPhenix steam generator database.
