The challenges and opportunities to alloyed and composite fuel architectures designed and
intended to mitigate oxidation of the fuel during a cladding breech of a water-cooled reactor …

Nuclear energy has been a part of the energy mix in many countries for decades. Today in
principle all power producing reactors use the same techniqe. Either PWR or BWR fuelled …

In this study, U 3 Si 2 was synthesized via the use of arc-melting and mixed with UN
powders, which together were sintered using the SPS method. The study revealed a number …

In this study, the oxidation of various accident tolerant fuel candidates produced under
different conditions have been evaluated and compared relative to the reference standard …

Dense uranium mononitride (UN) pellets with controlled microstructures and tailored grain
size from large-grained to a few microns are synthesized by spark plasma sintering (SPS) …

Uranium nitride (UN)-uranium dioxide (UO 2) composite fuels are being considered as an
accident tolerant fuel (ATF) option for light water reactors. However, the complexity related to …

Composite fuels such as UN-UO 2 are being considered to address the lower oxidation
resistance of the UN fuel from a safety perspective for use in light water reactors, whilst …

A procedure for electric pulse consolidation of commercial UO 2 powders of various ceramic
grades into high-density fuel pellets using dies of various types was studied. The influence …

Uranium mononitride (UN) pellets of different densities were subjected to a superheated
steam/argon mixture at atmospheric pressure to evaluate their resistance to hydrolysis …

In this work, a systematic study of the degradation of UN pellets (density range 96%–99.9%
and grain size of 6–24 µm) and UN-10% U3Si2 (wt%) composite in a steam environment is …
