Abstract

In severe accident of PWR,large amount of hydrogen may accumulate in the containment,combustion or detonation may occur and challenge the integrity of containment.Passive autocatalystic recombiners (PARs) should be installed to mitigate the hydrogen risk.Aiming at Lingao phase 2 nuclear power plant,using MELCOR and TONUS,a preliminary design of hydrogen mitigation system has been given.Different hydrogen mitigation systems are also compared in this paper.
- Large dry containment,
- Passive autocatalystic recombiners,
- Severe accident,
- Spontaneous hydrogen combustion
