DEVELOPMENT OF ANALYTICAL MODEL FOR SODIUM POOL COMBUSTION.

Abstract

An analytical model for sodium pool combustion has been developed and verified by experiments. 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 increases in gas temperature. Calculated combustion rates agree within 15% of the experimental results.
