“…The transuranic element (TRU) recovered through the pyroelectrochemical processing of spent light water reactor (LWR) fuels is used to fabricate metallic fuels [1]. The extracted TRU, including Pu and long-lived minor actinides (MA) such as Np, Am, and Cm, are used to fabricate metallic fuels [2,3]. This fuel recycling can solve the problem of pressurized water reactor (PWR) spent fuel accumulation by reducing the overall volume of PWR spent fuel and increasing the utilization of uranium resources while maintaining a high proliferation resistance [4].…”

FABRICATION OF U-10WT.%Zr-RE FUEL SLUGS BY RECYCLING OF METALLIC FUEL SCRAPSU-10wt.%Zr-5wt.%RE fuel slugs for a sodium-cooled fast reactor (SFR) were conventionally prepared by a modified injection casting method, which had the drawback of a low fabrication yield rate of approximately 60% because of the formation of many metallic fuel scraps, such as melt residue and unsuitable fuel slug butts. Moreover, the metallic fuel scraps were classified as a radioactive waste and stored in temporary storage without recycling. It is necessary to develop a recycling process technology for scrap wastes in order to reduce the radioactive wastes of the fuel scraps and improve the fabrication yield of the fuel slugs. In this study, the additive recycling process of the metallic fuel scraps was introduced to re-fabricate the U-10wt.%Zr-5wt.%RE fuel slugs. The U-10wt.%Zr-5wt.%RE fuel scraps were cleaned on the surface impurity layers with a mechanical treatment that used an electric brush under an Ar atmosphere. The U-10wt.%Zr-5wt.%RE fuel slugs were soundly re-fabricated and examined to evaluate the feasibility of the additive process compared with the metallic fuel slugs that used pure metals.
