Abstract
In the framework of the European project Nuresafe, the reactor dynamics code Dyn3D, developed at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), was coupled with the Computational Fluid Dynamics (CFD) solver Trio U, developed at CEA France, in order to replace Dyn3D’s one-dimensional hydraulic part with a full three-dimensional description of the coolant flow in the reactor core at higher spatial resolution. The present document gives an introduction into the coupling method and shows results of its application to the simulation of an Main Steamline Break (MSLB) accident of a Pressurised Water Reactor (PWR).
Keywords: reactor safety; code coupling; thermal hydraulics; computational fluid dynamics; reactor dynamics
