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