Analysis of mass transfer effect on chemically produced iodine release from aqueous phase

Zablackaite, G.; Shiotsu, Hiroyuki ; Kido, Kentaro ; Sugiyama, Tomoyuki

To investigate the mass transfer effect on the overall iodine release to the environment, we propose a chemical-process-reduced mass transfer (CPR-MT) model for iodine that is based on two-film theory and includes an effective mass transfer coefficient ( $tilde{k}_{mt}$ ). By formally decomposing $tilde{k}_{mt}$ into iodine chemistry and mass transfer contributions, we discuss their impact for a variety of severe accident conditions of nuclear power station.
