Abstract

Experimental studies have been undertaken to characterise the behaviour of fission products in the containment of a pressurised water reactor during a severe accident. The following aspects of fission product transport have been studied: aerosol nucleation, vapour transport processes, chemical forms of high-temperature vapours, interaction of fission product vapours with aerosols generated from within the reactor core, resuspension processes and the chemistry of containment. Chemical effects have been shown to be important in defining and quantifying fission product source terms in a wide range of accident sequences. Both the chemical forms of the fission product vapours and their interactions with reactor materials aerosols could have a major effect on the magnitude and physicochemical forms of the radioactive emission from a severe reactor accident. Only the main conclusions are presented in this summary document. Detailed technical aspects of the work are described in separate reports listed in the annex.
