Uranium mononitride (UN) is a promising nuclear fuel that combines the advantageous
properties of readily used UO 2 and uranium alloys, such as high melting temperature and …

Abstract Cr-incorporated UN (Cr-UN) composite fuels with different Cr amounts up to 10 wt%
are fabricated by spark plasma sintering, and their microstructure and phase heterogeneity …

The application of digital twin (DT) technology to the nuclear field is one of the challenges in
the future development of nuclear energy. Possible applications of DT technology in the …

Microstructure and Cr2O3 doping profoundly impact the thermal-mechanical properties and
fracture of oxides fuels. It is a challenge to study the transient behavior of nuclear fuels under …

Nitride ceramics have been investigated for different applications in the nuclear industry,
such as space nuclear power, fusion reactor diagnostics and plasma heating, inert matrix …

Abstract Both UN and U 3 Si 2 are potential candidates for accident tolerant fuels due to their
high fissile element density and exceptional thermal conductivity. However, they display a …

Uranium nitride (UN) is considered to be a very promising candidate of accident-tolerant
fuel. Since UN is commercially synthesized by carbothermic reduction-nitridation, the carbon …

The oxidation susceptibility of UN Σ5 (210) grain boundary (GB) decorated with Al, Cr or Ni
is assessed by first-principles modelling. The predictions show that the low segregation …

Metallic uranium is a leading fuel form for sodium cooled fast reactors as an enabling
technology of future nuclear energy systems. Mechanistic understanding of fuel behaviors …

To accommodate the swelling of metallic fuels induced by the fission gas release for a
sodium-free fuel option, advanced U-10Zr fuels with controlled porosities were designed …
