“…If melt growth is eschewed because of these assorted shortcomings, the next most common growth techniques dissolve the feedstock under conditions well below the melting point and then crystallize out the feedstock from the solution. Chemical vapor deposition (CVD) or chemical transport (UO 2 , − U x Th 1– x O 2 , and U 1– x Pu x O 2 ), flux (CeO 2 , − ThO 2 , ,,− ,− UO 2 , ,, U x Th 1– x O 2 , and PuO 2 ,− ), and hydrothermal or solvothermal synthesis (CeO 2 , ThO 2 , ,,,− U 1– x Th x O 2 , − UO 2 , − ,− and PuO 2 ) fall into this category and have been employed for the entire AO 2 family. High-quality, well-faceted single crystals of ThO 2 and UO 2 produced using the hydrothermal method are shown in Figure .…”

To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts seek solid fuels that must withstand unprecedented temperature and radiation extremes. In these advanced fuels, thermal energy transport under irradiation is directly related to reactor performance as well as reactor safety. The science of thermal transport in nuclear fuel is a grand challenge due to both computational and experimental complexities. Here, we provide a comprehensive review of thermal transport research on two actinide oxides: one currently in use in commercial nuclear reactors, uranium dioxide (UO2), and one advanced fuel candidate material, thorium dioxide (ThO2). In both materials, 5Concluding Remarks .
