Scrubbing of radionuclide aerosols in water pools

An engineering model is developed for predicting the removal of aerosol fission products from steam-noncondensable gas mixtures rising through water pools. The pool is divided into a gas injection zone, a bubble-swarm rise zone and a pool surface zone. The mathematical model is composed of a quasi-steady one dimensional formulation for the gas phase, and a time dependent, well-stirred formulation for both the liquid phase in the pool and the gas phase in the compartment above the pool. The developed computer code Suppression Pool Retention Analysis (SUPRA) incorporating the formulated mathematical models is described. Results of parametric calculations are given, which examine the effect of key inlet and pool parameters on aerosol scrubbing. Validation calculations are provided, where the predictions of the SUPRA code are compared against hydrodynamics and aerosol scrubbing experimental data
