LBLOCA analysis for the Maanshan PWR nuclear power plant using TRACE

In this study, the large break loss of coolant accident (LBLOCA) analysis model is established by TRACE/SNAP code and the LBLOCA analysis results are compared with the Maanshan FSAR data. The main structure of this model includes the pressure vessel, pressurizer, steam generators, and safety injection of ECCS. In summary, the analysis results by TRACE LBLOCA model are consistent with FSAR data. The TRACE LBLOCA model of Maanshan NPP can be used in future safety analysis with confidence.
