Progress of severe accident (SA) can be divided into core degradation and post core
meltdown. An important phenomena during severe accidents is the hydrogen generation …

Under the severe accident of the nuclear reactor, the strong coupling phenomenon exists
between the transport and condensation of the steam-air-hydrogen multi-component gas in …

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 …

In the accident conditions, the operational behavior of passive autocatalytic recombiners
(PARs) has garnered significant attention, particularly with regards to the complicated …

This paper presents a sensitivity study of nodal scheme in MELCOR simulation of severe
accidents in a pressurized water reactor, with the objective to estimate the nodal effects on …

This paper describes a numerical study of the influence of thermal diffusion (the Soret effect)
on the operational behaviour of a passive autocatalytic recombiner (PAR). The study …

The benchmark exercise discussed in this paper was conducted within the OECD/NEA
project HYMERES. The specific experiment in the PANDA facility chosen for the present …

Under severe accident conditions of a pressurized water reactor, hydrogen will be released
into the containment, forming a mixture of steam-air-hydrogen, and then transported to the …

The relative content and transport behavior of steam-air-hydrogen are of vital importance for
nuclear power plants under severe accidents. Since there are many cold walls in the nuclear …

This study aims to assess whether a computational fluid dynamics (CFD) approach
effectively simulates hydrogen recombination characteristics by a passive autocatalytic …
