Hydrogen could be generated by an active reaction of the fuel-cladding and the steam in the reactor pressure vessel during a hypothetical severe accident in a nuclear power plant (NPP). In such situation, the generated hydrogen is released together with steam into the containment. In order to mitigate hydrogen hazards which could possibly occur in the NPP containment, a hydrogen mitigation system (HMS) is usually adopted, such as hydrogen igniters and passive autocatalytic recombiners (PAR). In this study, an analysis of the hydrogen and steam behavior has been numerically performed using fully 3-dimensional computational fluid dynamics (CFD) technique, during a total loss of feed water (LOFW) accident in the OPR1000 containment. During the accident, a huge amount of hot water, steam, and hydrogen are released into the containment. The possibilities of flame acceleration and a transition from deflagration to detonation (DDT) are evaluated by using the Sigma?ambda criteria.
