Résumé

Pending Post-Test-Analysis results, this paper gives an overview of the behaviour of fission products and control-rod/structure materials in the Phébus FPT2 test, based on the analysis of gamma spectrometry measurements performed on site (on-line measurements performed during the test, and post-test measurements performed on sampling devices and bundle/circuit sections). A tentative coherence analysis is presented, by comparing data obtained from independent measurements and at various locations of the experimental set-up, in order to discuss the observed phenomena: release, transport and containment behaviour. A preliminary comparison to the FPT1 test is proposed.
