Evaluation of the consequences of sodium pool fire requires a prediction model that can calculate the fractions of the aerosols of Na2O and Na2O2 being transported into the atmosphere and onto the sodium pool surface from the reaction zone. In the present model, we applied the laminar diffusion flame theory in a thin layer in the neighborhood of the pool surface. The combustion was modeled assuming the instantaneous chemical equilibrium because the chemistry is fast compared with the mixing. The aerosol transport was assumed to be due to a sum of the drag force, the thermal force and the gravity. The calculated results are in good agreement with experimental data obtained by other investigators for the burning rates and the aerosol release fractions of sodium pool fire. This analysis forms the basis of prediction of aerosol release fraction in the sodium pool fire.
