摘要：

A new model of iodine-Epoxy paint interaction under irradiation has been developed with new relevant data to better reproduce and predict how much iodine could be released in the environment in case of a severe accident in a Pressurized Water Reactor. Its application to the modelling of volatile iodine behaviour in PHEBUS-FPT-3 test is presented and shows that other phenomena might govern the iodine volatility in the mid and long term. A broader analysis of the gaseous iodine behaviour is finally presented, highlighting the need to identify and model new gaseous chemical reactions that might play a significant role on iodine volatility.
