Abstract The third International Benchmark Exercise (IBE-3) conducted under the auspices
of OECD/NEA is based on the comparison of blind CFD simulations with experimental data …

In the appearance of steam, the CFD modeling of thermal-hydraulic phenomena in reactor
containments during various phases of an accident necessarily requires consideration of …

PANDA is a large-scale, multi-compartment, thermal-hydraulics facility located at the Paul
Scherrer Institute (PSI) in Switzerland and is operated for nuclear safety projects. PANDA is …

As one looks forward to applying CFD based methods to simulate turbulent flows in larger
volumes up to containment scales, the mesh resolution, especially near the walls, becomes …

During a severe accident in light water reactor (LWR), hydrogen concentration can overpass
the flammability limits locally, so the correct simulation of its behavior during a release is …

Hydrogen leaking inside a nuclear power plant poses a critical nuclear safety issue, and
accurate prediction of the dispersion process of hydrogen has become an important topic of …

Turbulent gas mixing in a buoyant flow with density gradient is an important physical
mechanism in many applications ranging from industrial gaseous emissions into the …

Abstract The Stress Tests accomplished by the European nuclear plants assume to be a
complementary and comprehensive review of the safety of nuclear facilities, taking into …

Hydrogen management is still one of the main nuclear safety topics because of its violent
reaction with oxygen. During a severe accident, hydrogen can be generated and it can be …

This paper presents the gas distribution analysis by injecting air fountain into the
containment and simulations with the HYDRAGON code. Turbulence models of standard k-ε …
