Status of interpretation of the first Phebus FP test FPT0
This series of slides presents an overview of the first Phebus FP test. It details the test objectives and conditions. Results are reported from the point of view of interpretation: bundle, circuit, containment thermal hydraulics and containment chemistry. Preliminary conclusions include many unexpected results, such as: (i) early and large fuel dissolution by Zr-rich mixtures in oxidising conditions; (ii) advanced degradation typical of late phase behaviour; (iii) surprisingly low FP retention in hot steam generator: (iv) unexplained large depositions of aerosol on containment wall; (v) early significant concentration in gaseous I in containment, not released by sump. These findings may result in extensive revisions of current understanding and modelling of severe accident phenomena and related source term for LWR.
