Japan Atomic Energy Agency (JAEA) has been developing the technology on transmutation of MA under the double strata fuel cycle concept. A combination of uranium-free Pu-MA-Zr nitride fuel and pyroprocessing has been chosen as the first candidate for MA transmutation fuel cycle using accelerator-driven system (ADS). This paper introduces the recent progress ondevelopment of pyroprocessing technology for MA transmutation nitride fuels. It contains a detailed design of the flowsheet on the electrorefining process of the spent fuels and the behavior of metal elements in renitridation process.
