Gaseous fission product generation, transport, and release can have a large impact on
nuclear fuel performance, degrading fuel and fuel–cladding gap properties. Over the past …

Gaseous fission product transport and release has a large impact on fuel performance,
degrading fuel and gap properties. While gaseous fission product behavior has been …

Based on density functional theory (DFT) and empirical potential calculations, the diffusivity
of fission gas atoms (Xe) in UO 2 nuclear fuel has been calculated for a range of non …

Diffusion of fission gas in UO 2 nuclear fuel impacts several important performance metrics,
such as fission gas release, swelling, and thermal conductivity. Current empirical models of …

Fuel performance codes are critical tools for the design, certification, and safety analysis of
nuclear reactors. However, their ability to predict fuel behavior under abnormal conditions is …

Over the last decade, a significant amount of work has been devoted to point defect
behaviour in UO 2 using approximations beyond density functional theory (DFT), in …

By means of an ab initio plane wave pseudopotential method, the behavior of helium in
UO2, PuO2, AmO2 and (Am0. 5Pu0. 5) O2 and of xenon in UO2 is studied. We first show that …

Uranium dioxide, UO2, is widely used as fuel in nuclear power generation. In the high burn-
up of the fuel, the radial periphery of UO2 pellets forms a characteristic fine grain, which is …

A computational study of some fission products (FP) energetics in uranium dioxide is
presented. Krypton, iodine, caesium, strontium and helium are considered. Calculations are …

Defects in semiconductors have been studied for many years, in many cases with a view
toward controlling their behaviour through various forms of “defect engineering”. For …
