PRESSURIZED WATER NUCLEAR REACTOR EXCLUSIVELY LOADED WITH MIXED OXIDE FUEL, AND CORRESPONDING NUCLEAR FUEL ASSEMBLY

摘要

The invention relates to a pressurized water nuclear reactor (1), including a core (2) containing nuclear fuel assemblies (16), wherein all the assemblies (16) exclusively comprise mixed uranium oxide and plutonium oxide fuel rods before irradiation. For each assembly (16), the nuclear fuel rods have the same isotopic nuclear fuel composition and the same nominal plutonium weight content.
