A numerical method for the compressible 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 reacts 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 in sodium-water reaction are calculated by using a surface reaction model and a gas phase reaction model. Through the numerical analysis of a sodium-water reaction test SWAT-1R, prediction capability for the temperature field was verified. Sensitivity analysis to investigate the effect of model parameters was also performed.
