Thermal-Hydraulic Analysis of the Nuclear Power Engineering Corporation Containment Experiments with GOTHIC

Assessment of the Depressurisation and Mixing Effects of Two Spray Systems in the Panda Facility, Part Ii – Simulations Using Gothic8.3(Qa)

“…The simulations reproduced the experimental recordings of the pressure of PANDA only by decreasing the spray mass flow rate. In the literature, we could find another article where decreasing the spray flow rate was the only way to reproduce the experimental pressure recorded in NUPEC containment experiments (Wiles and George, 2003). The previous simulation of spray experiments in PANDA with GOTHIC also predicted a pressure decrease faster than the experiments (Andreani and Erkan, 2010;Vázquez-Rodríguez et al, 2022a).…”
