TEXAS-V: A FUEL-COOLANT INTERACTION MODEL
RÉSUMÉ
The fuel-coolant interaction is a physical process which may occur during a severe accident in a nuclear power plant when molten fuel contacts coolant water. The hazard from such an interaction depends on the geometrical conditions in which the fuel and coolant contact, although fuel pouring into a coolant pool is a common mode observed in industrial accidents. To this end, the TEXAS computer model has been developed at the University of Wisconsin to analyze such fuel-coolant interaction events when fuel pours into water. The most recent improvements in the TEXAS model are presented in this paper, with the focus of analysis being experiments currently being conducted at the Joint Research Center, Ispra. The paper presents the context for the model, briefly describes its basis and then focuses on current improvements underway and analyses with the TEXAS-V model.
