Core LOSS during a severe accident

Objective

R&D work for 1300-PWR, BWR, VVER on risk-relevant core degradation issues is proposed with experiments at different scales up to integral tests.
Selected topics with large databases uncertainties are:
a)impact of high burn-up on UO2 and MOX dissolution
b)identification of fuel or collapse conditions
c)oxidation of B4C by steam and B4C control rod degradation / oxidation with related gas generated (H2, CH4,..) U-o-Zr oxidation kinetics.
Topics b) and c) include different plant design components. The lack of exp. data means also non-validated or missing models in SA codes in spite of safety consequences e.g. H2 rate or production of CH4 with favour organic Iodine formation. Models developed will be implemented in SA codes. Expected results: 1/H2 and B4C decomposition gas release during core collapse, 2/ B4C/burn-up/collapse models included in SA codes, 3/ >Feedback on safety and consequences on AMMs for various plant designs.
