| Abstract: | Accompanied with the development of advanced reactor research, the stability problem becomes more and more important. The AEICE numerical algorithm, which is based on the EICE, is developed in this article. Furthermore, the AEICE is used to analyze system characteristics and thermo-hydrodynamic instabilities of boiling two-phase natural circulation system. It shows that increasing system pressure or inlet subcooling can enlarge the system stability region. The numerical results correspond well with the experimental data. |
