An analytical model for sodium pool combustion has been developed and verified by ex-periments. The model can be used to analyze sodium fire accidents in LMFBRs. It features a layer of sodium vapor between the flame and the sodium pool surface which functions to resist heat transfer. Results obtained with the model show : combustion rate increases with oxygen concentration, sodium pool temperature and gas pressure, but it decreases with in-creases in gas temperature. Calculated combustion rates agree within 15% of the experi-mental results.
