Abstract

Abstract

Taking a domestic Ⅲ generation pressurized water reactor nuclear power plant as an example, two typical severe accident conditions are selected, modeling and calculation with Modular Accident Analysis Program(MAAP) are carried out, and the process of containment venting and the hydrogen risk to the spent fuel building are analyzed. The results show that if the ventilation system of the spent fuel building is not considered, the mixed gas released from the containment will cause a certain hydrogen risk to the spent fuel building due to the condensation of water vapor. If the role of the ventilation system of the spent fuel building is considered, the hydrogen risk in the spent fuel building will be eliminated.
