Abstract
The concept of an Over-Moderated Reactor (OMR) which should accept 100% MOX reloads has been studied at the EDF R&D Division. This aims to be the plutonium version of the European Pressurized Reactor (EPR), which is developped jointly by French and German companies. A moderating ratio of 2.5 (instead of the standard value of 2.0) is obtained by replacing several fuel rods by water holes. The core would contain 241 Fuel Assemblies (FA). We present some advantages of over-moderation for plutonium fuel, a description of the core and assemblies, calculations of fuel reload schemes and Reactivity Shutdown Margins (RSM), and the behavior of the core during two accidental transients.
