  • In this study, hydrogen risk analysis of typical Chinese nuclear power plant under LOCA scenario is performed based on CFD codes. Hydrogen deflagration potential is analyzed basing on the flame acceleration criteria. Conservative model(CREBCOM) is chosen for the combustion simulation and the burning rate is defined based on the large scale combustion experiment data. Numerical simulation showed that the containment peak pressure during the combustion process approached 7.0 bar, which would potentially compromise the integrity of the containment.
