The behaviour of fission products (FPs) during a severe nuclear power plant accident has been studied at VTT for the past 25 years. The focus has been on the transport and chemistry of aerosols in the primary circuit and the containment. In the past containment aerosols have been studied e.g. with intermediate scale facilities AHMED and VICTORIA. In primary circuit the studies have included resuspension and revaporisation phenomena as well as retention of FPs in steam generators. In recent years the main interest has been on ruthenium and iodine, because of their high radiotoxicity and possibility to form gaseous compounds
