Description

It has been claimed that the chemical form of iodine released under severe accident conditions is cesium iodide. However, papers presented in this session of the workshop suggest that through reactions with boric acid or radiolytic effects more volatile iodine species could be released with important implications in reactor safety assessment. It should not be assumed that trace levels of oxygen would not be present following a severe PWR accident and experiments involving CSI reactions where oxygen is removed are probably irrelevant to real conditions. Previous experiments have been concerned with aqueous phase reactions but it is necessary to perform experiments in the gas phase. (UK)
