A test facility for the reproduction of fission poroduct release and transport under a severe accident condition has been developed. It was confirmed that not only deposited but also airborne materials in the farnace of this facility under temperature condition of severe accident (1000 - 400 K at reactor coolant system) can be subjected to various analyses by measuring aerosol size distribution of airborne CsI aerosol.
