When the water leaks from a failed heat transfer tube in a steam generator of sodium-cooled

fast reactors, the high-temperature jet with sodium-water chemical reaction may cause wastage

of the adjacent tubes. A computer program called SERAPHIM has been developed to

calculate the multiphase flow involving the sodium-water reaction. In this study, the

experiment on reacting gas jets in liquid pools was analyzed to validate the numerical models.

The numerical results showed that the injected gas disappeared at a certain height. The

calculated plume length showed good agreement with the experimental data. This analysis

demonstrated validity of the proposed models.
