摘要

•A high temperature bundle test was performed with rods pressurized to 6 MPa.•Results of post-test modelling performed by the ATHLET-CD and SOCRAT codes were compared.•Cladding ballooning and burst parameters measured during the test were adequately modelled.•Hydrogen production has been calculated within the uncertainty of the measured data.•Modelling of blockage formation due to melt relocation and solidification matches well to test data.
