Phebus-FP is an international project aimed at providing integral data on the release and transport of fission products under severe accident conditions. The programme comprises a series of in-pile experiments conducted at CE Cadarache and jointly funded by IRSN/EdF, EC and a number of other national organisations. The fourth test in the Phebus-FP programme, FPT2, was performed in October 2000 (Ref. [1]). Analyses of the iodine behaviour in the containment during this test have been made using various containment chemistry codes, mainly in the framework of the Pheben 2 programme (Ref. [2]). This report describes the main results of the FPT2 test regarding iodine behaviour in the containment, and the current status of interpretation and understanding reached through analysis with the ASTEC/IODE, IMPAIR, INSPECT and MELCOR codes.
