Thermal transport study in actinide oxides with point defects
Nuclear Engineering and Technology, 2019 We use a molecular dynamics simulation to explore thermal transport in oxide nuclear fuels with point defects. The effect of vacancy and substitutional defects on the thermal conductivity of plutonium dioxide and uranium dioxide is investigated.

Solution Synthesis of Actinide Chalcogenide and Oxychalcogenide Nanoparticles
Angewandte Chemie, EarlyView.We report the synthesis of UOS, UOSe, and US2 nanoparticles under colloidal conditions. The magnetic properties were measured of all three materials and compared to prior studies of UO2 nanoparticles. Nanoparticle phases were determined using powder diffraction, and size by transmission electron microscopy.

Comparing the corrosion of uranium nitride and uranium dioxide surfaces with H2O2 [PDF]
Journal of Nuclear Materials, 2018 Uranium mononitride, UN, is considered a potential accident tolerant fuel due to its high uranium density, high thermal conductivity, and high melting point. Compared with the relatively inert UO2, UN has a high reactivity in water, however, studies have
