AbstractSafety is of paramount importance inthe design and maintenanceof Nuclear Power Plants (NPP). The crucial area is the nuclear island,where irradiated elements are located. Fuel melt is a very dangerous possibility during serious incidents in the nuclear reactor core and could lead to the release of enormous amounts of ra- dioactive elements. Uranium Oxide (UOX) and Mixed Oxides (MOX) are currently being consideredas fuels for existing and planned NPPs. This paper addresses UOX and MOX fuel melt calculations using a prepared Thermal-Hydraulics (TH) model and reliable thermal conductivity of UOX and MOX fuel relations. This evaluation is performed for European Pressurized Reactor (EPR) geometry and thermophysical parameters.
