ABSTRACT
This paper describes the general neutronic characteristics of the Replacement Research Reactor (RRR) for the Australian Nuclear Science and Technology Organisation (ANSTO). An important neutronic characteristic of the RRR design is that it can safely handle two different types of LEU Fuel Assemblies (FA): the already internationally qualified U3Si2 fuel type with a Uranium density of 4.8 g/cm3, and the under qualification U-Mo fuel type with higher densities. This paper presents the fuel assembly characteristics and makes emphasis on the neutronic behavior of the new fuel type for different Uranium densities and Molybdenum contents. It compares the neutronic characteristics of the new fuel assembly with respect to the standard U3Si2 fuel type. The comparison includes the cycle length, several safety variables and irradiation fluxes.
