Abstract
A numerical method for the multi-phase multi-component flows with sodium-water reaction was developed. When the pressurized water leaks from a failed heat transfer tube in the steam generator of sodium cooled fast breeder reactors, the water will react with the sodium outside the tubes. In order to simulate the multi-phase multi-component flows, the multi-fluid model and the advection-diffusion equations are used in our numerical method. Production rates of the components such as the sodium hydroxide and the hydrogen by sodium-water reaction are calculated by using the surface reaction model and the gas phase reaction model. Through the numerical analysis of the sodium-water reaction test SWAT-1R, validity of the numerical method was demonstrated.
