Abstract

Recent results of experimental studies, as well as computer modeling of the helium behavior in uranium-based nuclear fuels, are reviewed. Potential models of interaction of helium atoms, uranium and oxygen ions, results of application and perspectives of computer simulation methods in prediction of the most important properties of solid solutions of helium, such as its solubility and diffusion coefficients in stoichiometric and nonstoichiometric uranium dioxide, are discussed.

Key words:  helium, interaction, molecular dynamics, solubility, diffusion.
