A comprehensive literature survey has been carried out on modelling and experimental measurements relating to vapour retention in water pools, in the context of LWR accidents. The pool scrubbing codes considered in the modelling review were ART, BUSCA, SPARC and SUPRA. The comparison considered aerosol and soluble gas removal processes, bubble thermal hydraulic modelling, the structure of the code and its input and output requirements. On the basis of the results of this comparison, the BUSCA code has been improved and integrated into the ESTER (European Source Term Evaluation Reference) code package. New models that have been added include bubble break-up effects, bubble swarm rise velocities and bulk condensation calculations. An out-of-pile experimental programme was performed at the LACE-Espana test facility at CIEMAT to test the retention of soluble FP-compounds under pressure conditions. Pre- and post-test calculations were carried out using BUSCA and SPARC.
