TL;DR: The NEPTUNE project constitutes the thermal-hydraulic part of the long-term Electricite de France and Commissariat a l'Energie Atomique joint research and development program for the next generation.

TL;DR: In this paper, the authors focus on the modeling and numerical simulation with the NEPTUNE_CFD code of cavitation phenomena and boiling bubbly flows and propose a modification of the classical nucleate boiling model to overcome the strong model sensitivity with respect to near wall grid refinement.

TL;DR: The ECORA project as mentioned in this paper evaluated CFD software for reactor safety applications, resulting in best practice guidelines (BPGs) for an efficient use of CFD for nuclear safety problems.

TL;DR: In this paper, the influence of the turbulence model on target variables linked to CHF limitation is discussed, and the sensitivity to the mesh refinement is particularly examined in the context of fuel assembly analysis or design by means of CFD codes.

TL;DR: In this article, the effect of angles and position of mixing vanes and the main physical phenomena (wall boiling, entrainment of bubbles in the wakes, recondensation) are investigated.
