The purpose of this research is to estimate the magnitude of fission product and aerosol release from the PWR NPP containment during Large Break Loss of Coolant Accident (LB-LOCA) up to 24 hr as severe accident scenario without considering the safety injection systems(SIS) using MELCOR1.8.6. The results show that, 174kg radioactive materials are discharged into the containment and 118 kg of this amount are related to the airborne material including aerosols and vapors.
