Feasibility of nitride fuel lead cooled Breed-and-Burn fast reactor with rotational fuel shuffling (RFBB-NL) was analyzed. The fuel assemblies are moved circular approaching to the core center by the shuffling. By setting the reactor power 750 MWt and the shuffling interval 605 days, the reactor can be critical in equilibrium condition, in which the discharge burnup is 32% in FIMA and the dpa is about 620.
