An applicable approach for mitigating the hydrogen risk in severe accident conditions is the use of hydrogen recombiners inside the reactor containment compartments. In this study, three major possible hydrogen-producing accidents are simulated by Relap5/SCDAP and MELCOR codes including a large break loss of coolant accident (LBLOCA) in cold leg, station blackout (SBO) accident and LBLOCA+SBO to determine the appropriate arrangement of RVK-500 hydrogen recombiners inside the VVER-1000/V446 reactor containment. The results show that the final proposed layout for hydrogen recombiners is able to decrease the maximum peak of hydrogen mole fraction for the three mentioned accidents by 0.00, 14 and 10.3%, respectively.
