| Abstract: | Largescale hydrogen combustion and detonation in the containment building may threaten the integrity of the containment when a postulated severe accident takes place in a light water reactor nuclear power plant. Hydrogen recombiners and igniters are two promising hydrogen mitigation equipments under severe accident. Three mitigation measures, including using igniters only, employing hydrogen recombiners only and adopting the combination of recombiners and igniters, were investigated in this paper. The analysis results indicate that combination of hydrogen recombiners and igniters can mitigate the risk of hydrogen combustion in a safe, continuous, and effective way. |
