Simulation study on the transient operating characteristics of equal height difference passive containment cooling system
The passive containment cooling system is crucial important for marine nuclear power platform. This paper focuses on the transient characteristic of passive containment cooling system with equal height difference natural circulation under two starting strategy. Dynamic simulation model of passive containment cooling system is set up with APROS software. The simulation results indicate that the initial containment pressure, initial non-condensable gas content, and inlet water temperature have important effects on the pressure drop rate and natural circulation flow rate. And obvious differences exist between the empty tube starting mode and the full tube starting mode. Under single-phase natural circulation conditions, the pressure drop rate of the empty tube starting mode is more than 3.1 times that of the full tube starting mode, while under two-phase natural circulation conditions, the pressure drop rate of the empty tube starting mode is more than 1.5 times that of the full tube starting mode, since large fluctuation amplitude of two-phase flow instability caused by condensation induced water hammer in the natural circulation occurs under full tube starting mode.
期刊介绍：
Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
