“…The Zr-rich precipitates, stabilized by dissolved impurities such as N, O, and C, have been observed in a variety of transmutation fuels. [14][15][16][17][18][19][20] In previous studies, these Zr-rich precipitates were assumed to be a-Zr that formed during alloy preparation because of the interstitial impurities present in the feedstock. [14] Our previous investigation of the U-Pu-Zr fuel showed the formation of Zr precipitates in the vicinity of the specimen surface.…”

This work investigates fuel-cladding chemical interaction (FCCI) between U-25Pu-14Zr (in wt pct) fuel and pure Fe at elevated temperatures, understanding of which is critical for evaluation of the fuel performance. Phases and microstructure formed in the quaternary uranium-plutonium-zirconium-iron (U-Pu-Zr-Fe) system were characterized using the transmission electron microscopy technique. Phases formed within the FCCI layer were identified using selective area electron diffraction (SAED) analysis as Fe 2 U (Fd-m), Fe 2 Zr (Fd-3m), a-U (Cmcm), Fe 2 Pu (Fd-3m), b-Pu (C12/m1), and b-Zr (Im-3m).

“…During the earlier campaign, more than 30,000 fuel pins were remotely fabricated in the FCF (Fuel Conditioning Facility), the proposed location for RSFFF. Small scale research conducted as part of the Advanced Fuel Cycle Initiative (AFCI) Fuel Development Program has shown that americium loss issues associated with the fabrication of the americium-bearing X501 experiment in the early 1990's [3] are understood and can be overcome using relatively simple engineering measures.…”

“…An early attempt at injection casting a UPu-Am-Np-Zr alloy resulted in losses of some of the the initial americium charge. 5 In a large-scale injection casting process of this type it is difficult to retain a volatile alloy component like americium due to the long times that the alloy constituents are in the molten state, resulting in opportunity for the volatile constituents to vaporize from the melt. Likewise, conventional powder processing methods yielded poor quality products, with large americium losses.…”

How would you……describe the overall signifi cance of this paper?For the Global Nuclear Energy Partnership to successfully support the increased utilization of nuclear power, new nuclear fuels will need to be developed that contain long-lived minor actinides that can be transmuted into elements with shorter half-lives. This paper describes the materials challenges associated with developing this type of fuel in a metallic form.…describe this work to a materials science and engineering professional with no experience in your technical specialty?New fuels are being developed that can be used in a nuclear reactor for transmuting long-lived radio-nuclides into ones that are shorter-lived and therefore are easier to dispose of in a geologic repository. This paper describes the types of materials challenges associated with the development of a metallic transmutation fuel. …describe this work to a layperson?Some constituents of irradiated fuel from a nuclear reactor can remain radioactive for a very long time. By taking these elements from the spent fuel and "burning" them in a fast reactor, elements can be produced that are radioactive for shorter time frames. Shorter-lived elements are easier to store in a geologic repository. This paper describes work to develop a metallic fuel that can be used to burn long-lived radioactive elements in a fast reactor.Metallic alloys show great potential to serve as transmutation fuels that could be used to burn long-lived and high-heat-producing minor actinides and fi ssion products in nuclear reactors as part of the Global Nuclear Energy Partnership program. To implement these fuels, work is ongoing to develop fuel fabrication processes, characterize alloy microstructures, measure fuel properties, determine the compatibility of fuel and cladding alloys, and understand the performance of the fuel alloys during irradiation.
