Abstract

Based on the on-line measurements carried out at Halden as well as on data available from the Super-Ramp project included in the OECD/NEA-IAEA International Fuel Performance Experiments(IFPE) database, a critical analysis is made of the fuel rod behaviour during operational transients by means of the TRANSURANUS fuel performance code. More precisely, recent model changes proposed for the transient gas release and swelling, along with suggestions for an improved simulation of pellet-cladding interaction, are being discussed.
