Abstract
Both accident transients, for each type of nodalization, were simulated for 200,000â¯s. At the end of the simulated transient, results showed that for the Large Break Loss of Coolant Accident pressure is predicted to surpass 5â¯bar, while the Station Black Out scenario is calculated to reach 4.4â¯bar. The performed sensitivities were simulated for 100,000â¯s and were meant to understand and characterize the impact of the different nodalization parameters (geometrical aspects, material properties, BCs). In addition, due to several code anomalies identified, several other sensitivity calculations were performed in order to find a way to analyse and mitigate the issues.
