Severe accident in a water-cooled nuclear power plant may lead to the production and
release of hydrogen. If hydrogen forms flammable gas with air and steam in the containment …

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 …

Abstract The evaluation of Passive Autocatalytic Recombiners (PARs) performance has
been foreseen from the EU stress tests in the framework of a complementary and …

The thermal-hydraulics phenomena in a containment during an accident will necessarily
include radiative heat transfer (i) within the gas mixture due to the high radiative absorption …

Abstract During a Loss of Coolant Accident (LOCA) accident, leaked hydrogen from the
primary circuit can form a stable stratified layer at the top of the containment building. The …

Hydrogen leakages into enclosed spaces may occur in hydrogen storage and usage
facilities and in nuclear power plants (NPP) following a severe accident. In the absence of …

Containment safety analyses of Design Basis Accidents (DBAs) rely on the use of Lumped
Parameters (LP) codes, and therefore, on pressure and temperature averaged values. In …

AP1000® is a Generation III+ reactor in which all safety systems relay on passive elements.
AP1000 containment includes an In-containment Refueling Water Storage Tank (IRWST), a …

This document explores the role of CFD in nuclear safety studies, with a particular focus on
advancements in Spain and Portugal. The field of nuclear safety has increasingly included …

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 …
