The PHYSOR project conducted by ALTRAN TECHNOLOGY is part of the research and development theme of new small modular reactor SMR concepts. An innovative project aims to improve the performance, design and safety of an SMR installation by integrating new technologies. In the SMR facilities, the steam generator (SG) plays an important role in the transmission of energy between the primary circuit and the secondary circuit of the reactor. For this, we have interested in this work to study the thermo-hydraulic behavior of steam generator. The aim of this paper is to develop a numerical model to simulate the heat exchange within the SG. The approach used in these numerical tools varies considerably according to the required accuracy. This paper gives a short overview of the early development of a tool that aims to describe the thermal and fluidic behavior of heat exchanger. The modelling approach is based on an averaged resolution of the Navier-Stokes equations using a coupling method between the primary and the secondary circuits. The results concerning temperature contours and velocity profiles for the two circuits were studied for different cases. The method used features a suitable compromise between results accuracy and time consuming numerical simulation. [ABSTRACT FROM AUTHOR]
