Modern computer codes play an important role in nuclear safety analysis. This paper presents the investigation of a station blackout accident at a VVER 1000 NPP with the codes Relap5 mod 3.2 Scdap and Melcor 1.8.5. A special interest was taken in the hydrogen production. A large amount of hydrogen could pose a serious threat to the containment. User choices have a considerable influence on the amount of produced hydrogen. The results from the calculations are presented and discussed. The results show in general a good agreement between the calculations.

Abstract
Modern computer codes play an important role in nuclear safety analysis. This paper presents the investigation of a station blackout accident at a VVER 1000 NPP with the codes Relap5 mod 3.2 Scdap and Melcor 1.8.5. A special interest was taken in the hydrogen production. A large amount of hydrogen could pose a serious threat to the containment. User choices have a considerable influence on the amount of produced hydrogen. The results from the calculations are presented and discussed. The results show in general a good agreement between the calculations.File in questo prodotto:
