Abstract
For EDF pressurized water reactors, numerical simulation of core thermal-hydraulics is essential for design and safety studies. THYC-cœur code, developed by EDF R&D, meets this need, allowing to take into account physical constraints. The core, a media packed with various solids, has historically been modeled using homogenized Navier-Stokes equations. Here, we are pursuing the implementation and industrial validation of a new approach to model the core : the integral formulation, based on a non-homogenized model. A verification test case is developed, enabling corrections to be made to its implementation in THYC-cœur. Geometry modeling is extended to multi-assembly cases, and a set of industrial validation cases is treated.
