Pool scrubbing could play an important role in the mitigation of severe nuclear accidents involving the release of contaminated gases through water pools. Examples of situations where this might occur include PWR quench tanks, BWR suppression ponds, certain V-sequences, steam generator tube rupture accidents and core-concrete interaction releases through overlying water pools. A critical review has been carried out of the modelling and experimental data on aerosol and vapour retention in water pools. This involved the systematic comparison of available computer codes, and the selection of the most suitable code for further improvement and future inclusion in the Ester code. Busca was the code selected, and has now been extended to model the condensation of steam onto aerosol particles, taking into account curvature and solute effects. It has also been extended to treat the enhanced rise velocity of swarms of bubbles. Busca has been validated against the best available experimental data, namely data from ACE Phase A and the EPRI experiments.
