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 …

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 …

Hazard of hydrogen fast deflagration or explosion could highly lead to an over-
pressurization of nuclear reactor containment in case of severe accidents. In order to …

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

Hydrogen explosion, which represents a complex safety issue in the water-cooled Small
Modular Reactors (SMRs), could lead to over-pressurization and threaten the integrity of the …

Hydrogen combustion or explosion will lead to over-pressurization of the reactor
containment in case of severe accident caused by Station BlackOut (SBO) in an Small …

This paper deals with determination of the minimum number and identification of the best
configurations of passive autocatalytic recombiners (PAR) for the effective design of the …

Passive autocatalytic recombiners (PARs), owing to its excellent hydrogen removal
capability and passive characteristic, have been widely utilized to prevent the potential …

In the case of a nuclear severe accident, hydrogen produced by the metal-water reaction
and core-concrete interaction is released in the containment in which large amounts of …

Passive auto-catalytic recombiner (PAR) system is an important hydrogen mitigation method
which has been applied in most modern light water nuclear reactors. The two challenges for …
