The Chemistry of Iodine in Containment

摘要: Recent investigations of iodine behavior under radiolytic conditions have demonstrated that kinetics, not thermodynamics, will govern speciation and partitioning typical those expected in a reactor containment during an accident. In the presence radiation, volatility is orders magnitude higher than based on thermodynamic calculations. Kinetic studies contributed extensively to existing database chemistry several implications for modeling safety analyses. For example, as result these investigations, many uncertainties database, such regarding thermal oxidation iodine, which were formerly regarded issues, are now considered be relatively unimportant. contrast, previously unconsidered factors, effect aqueous impurities originating from surfaces, recognized playing major roles determining volatility. An updated review literature provided, with focus recent developments. A critical evaluation data context developing model accident also provided.
