Abstract

Abstract

The effects of different spray models on the accident progress after the power recovery at blackout accident in Daya Bay Nuclear Power Plant were compared by MELCOR code. The result showed that the hydrogen combustion can be avoided or mitigated substantially by shorter spray duration and proper start time to activate the spray, and thus the time for the pressure in the containment reaching the limit can be retarded.
