Abstract

Abstract

The integrated severe accident analysis model of 100 MW PWR NPP is built to analyze the hydrogen risk under severe accidents.Large break loss of coolant accident（LB-LOCA）,medium break loss of coolant accident（MB-LOCA）,small break loss of coolant accident（SB-LOCA）,station blackout（SBO）,steam generator tube rupture（SGTR） and main steam line break（MSLB） are chosen as typical severe accident sequences to analyze the hydrogen source.Considering the hydrogen quantity of 100% zirconium water reaction,the LB-LOCA is selected as a representative sequence to evaluate the hydrogen mitigation system.The results show that a certain number of PARs could remove hydrogen and oxygen effectively,and protect the containment integrity against hydrogen de agration or detonation.
