High-level radioactive wastes from the Purex process contain long-lived nuclides, which mainly consist of transuranic elements (TRUs). This paper evaluates a partitioning and transmutation method that consists of pyrometallurgical partitioning of TRUs from Purex waste from light water reactor fuel and transmutation using a metal-fueled fast breeder reactor (FBR). The results indicate that the concept is feasible and has many advantages over conventional concepts based on wet processes and that transmutation of TRUs in a metal-fueled FBR is advantageous over that in a oxide-fueled FBR.
