Preliminary Core Design Analysis of a Dedicated Burner Loading Thorium-based Oxide Fuel

TORIA using thorium- based oxide fuel aims to incinerate the rest, leaving behind only low and intermediate level wastes. Hence, the aim of this study is to design a dedicated burner which is loading thorium and TRU to incinerate the residue. Critical TORIA shows enough TRU burning capability, but reactivity swing is large. This critical core design is the preliminary step for a dedicated burner design having accelerator driven system. It is expected to be useful in the step of detailed subcritical core design by understanding characteristics of core loaded with thorium-based oxide fuel. Accelerator driven system which is based on this critical TORIA aims to have destruction ability of 10kg per year, smaller reactivity swing, and longer refueling period than critical TORIA.
