“…A simplified schematic overview of current SNF recycle flowsheets is presented in Figure 4. Ion exchange (IX) finds use in uranium milling processes [65,66] and nuclear effluent treatment approaches [67]. Electrochemical methods are used in proposed pyroprocessing of SNF [68,69] for oxidation-state control in nuclear effluents [70] and have been proposed for use in fuel dissolution approaches [71], alongside several conceptual voloxidation (high-temperature oxidation) processes [27] (Ch.…”

Nuclear fuel is both the densest form of energy in its virgin state and, once used, one of the most hazardous materials known to humankind. Though commonly viewed as a waste—with over 300,000 tons stored worldwide and an additional 7–11,000 tons accumulating annually—spent nuclear fuel (SNF) represents a significant potential source of scarce, valuable strategic materials. Beyond the major (U and Pu) and minor (Np, Am, and Cm) actinides, which can be used to generate further energy, resources including the rare earth elements (Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, and Tb), platinum group metals, (Ru, Rh, Pd, and Ag), noble gases (He, Kr, and Xe), and a range of isotopes useful for medical and energy generation purposes are also produced during fission. One reason for the accumulation of so much SNF is the low uptake of SNF recycle (or reprocessing), primarily due to the high capital and operational costs alongside concerns regarding proliferation and wastes generated. This study will highlight the predominantly overlooked potential for the recovery of strategic materials from SNF, which may offset costs and facilitate advanced waste management techniques for minimised waste volumes, thus increasing the sustainability of the nuclear fuel cycle on the path towards Net Zero. Potential challenges in the implementation of this concept will also be identified.

“…The objective of this option is to prevent radiological hazard by isolating the waste for sufficient periods that allow the decay and limit release of short-and long-lived radionuclides, respectively [2,12,13]. To reach this end point, the wastes should be subjected to volume reduction (pre-treatment, and treatment), conditioning, and disposal in engineered facility [1,2,12,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Figure 2 illustrates an example of radioactive waste management scheme, and all the activities performed within the scheme should be complementary.…”

“…It should be noted that these activities are divided as predisposal and disposal activities, where transport, characterization and segregation, transportation, pre-treatment, treatment, conditioning, and storage are pre-disposal activities. Waste acceptance criteria (WAC) are applied at each facility to ensure integrated safe performance of the overall management schemes [27]. Each activity in this scheme should be authorized by the regulatory body according to national legislative system [28,33].…”

“…Each activity in this scheme should be authorized by the regulatory body according to national legislative system [28,33]. Different technological options could be applied in each activity; the selection of any is bounded by different technical and nontechnical factors [2,27]. Technical factors include the waste characteristics (chemical, physical, radiological, and biological), technology maturity, robustness, and flexibility, and site characteristics [2].…”

Research efforts that support the nuclear industry, as in any other industry, could be classified based on the maturity of the technology either commercial or innovative. These efforts are directed to improve the performance of the first class, whereas they aim at getting the second class into wide scale commercial applications [3]. Nuclear engineering research areas that cover the four identified industrial outputs could be listed as follows:

The scientific impact of this work is the protection of the environment from hazardous pollutants. Gamma irradiation was employed for the preparation of a new composite polymer by irradiating a mixture containing polyvinyl pyrrolidone (PVP), hydroxyethyl methacrylate (HEMA), and tannic acid (TA) to produce PVP–HEMA–TA. The sorption efficiency and capacity of PVP–HEMA–TA were evaluated by studying some factors affecting the sorption of Nd(III) and Co(II) from aqueous solutions. The results demonstrated that the maximum uptake was 92.4 and 75.3% for Nd(III) and Co(II), respectively. From the kinetic studies, the pseudo-second-order equation could better fit the data than the pseudo-first-order for the sorption of both ions. The sorption isotherm investigations illustrated that the Langmuir equation fits the gained data better than Freundlich equation. The Langmuir capacity was 64.5 and 60.8 mg/g for neodymium and cobalt ions, respectively. The applicability of Langmuir equation is strong evidence that the process is limited by a chemisorption mechanism. Findings of the work highlight the potential utilization of PVP–HEMA–TA as an effective and recyclable material for the elimination of Nd(III) and Co(II) from the aqueous phase.
