JAEA's R&D activities on nitride fuel research for transmutation of long-lived minor actinide (MA) are described. Nitride fuel containing MA as a principal component is proposed as a fuel material in sub-critical core of the Accelerator Driven System (ADS) developed by JAEA. Among the recent results, those on preparation of MA-bearing nitrides, property measurements of MA-bearing nitrides and burn-up simulated nitrides, pyrochemical treatment of spent nitride fuel and irradiation behavior of U-free nitride fuel are introduced.
