Mass transport is one of the most fundamental properties of a material and dictates its
potential use for a range of applications. In simple materials, mass transport is determined …

In this work, we present a model of fission gas behavior in U 3 Si 2 under light water reactor
(LWR) conditions for application in engineering fuel performance codes. The model includes …

U 3 Si 2 is a potential accident-tolerant fuel that shows promise due to its high thermal
conductivity and higher uranium density relative to UO 2. However, its swelling and fission …

Uranium nitride is a material of considerable fundamental interest and is a promising
candidate for an advanced nuclear fuel. We here study intrinsic point defects and …

Extensive attention has been paid to accident tolerant fuels (ATFs), such as uranium
mononitride (UN) and uranium sesquisilicide (U3Si2), which are regarded as potential …

U 3 Si 2 is an advanced fuel candidate due to its relatively high fissile density and attractive
thermal properties. Compared to standard UO 2 fuel, there are significant data gaps for the …

U 3 Si 2-SiC is an accident-tolerant fuel concept currently under development by
Westinghouse that has potential to improve economic performance and safety of light water …

A combination of density functional theory and empirical potential atomic scale simulations
have been used to determine a model for defect stability and mobility in uranium …

U–Si intermetallic compounds have drawn great attention due to their potential application
as nuclear fuels. However, the thermodynamic properties and phase equilibria of this binary …

In recent years, U3Si2 has been proposed as an alternative nuclear fuel material to uranium
dioxide (UO2) because of its intrinsically high uranium density and thermal conductivity …
