Application of SPS in the fabrication of UN and (U,Th)N pellets from microspheres

Phase and defect evolution in uranium-nitrogen-oxygen system under irradiation

“…(U,Pu)N) and composites are being considered as nuclear fuels or fuel components (e.g. tristructural isotropic particles) for advanced reactors such as liquid metal-cooled fast reactors and high-temperature gascooled reactors as well as light water reactors [27][28][29][30][31][32][33]. However, UN has unproven performance in accident scenarios, such as a fuel cladding breach where the fuel pellet would be exposed to water coolant or steam [34][35][36][37][38][39].…”

Preparation of Chromium doped uranium nitride via Sol-Gel and Carbothermic reduction

“…The higher carbon content compared to un-doped materials [21] can be explained by the lower theoretical amount of carbon needed for the Cr to react with respect to the uranium. Additionally, a higher amount of organic chemicals was used to be able to precipitate the chromium containing solutions.…”
