[en] • In-vessel retention (IVR) is one of the possible SA mitigation strategies ⇒ already implemented in several reactors currently operating (VVER440) or under construction (AP1000, APR1400, CPR1000+…); • In Europe, the feasibility of IVR for high power reactors still needs to be demonstrated: – Uncertainties regarding corium behaviour; – Penalizing hypotheses lead to an over conservative assessment of the thermal loads. • The IVMR project was launched to “improve the methodology by reducing the degree of conservatism in order to derive more realistic safety margins”. ⇒ extensive program covering experimental faculties and integral codes, but also the possible uses of CFD. • This presentation will focus on the work performed at EDF, partly in the frame of the IVMR project, using the NEPTUNECFD software.
