We present a theoretically-motivated model of helium bubble density as a function of volume
for high-pressure helium bubbles in plasma-facing tungsten. The model is a good match to …

Helium diffusion, clustering and bubble nucleation and growth is modelled using the finite
element method. The existing model from Faney et al.(Model Simul Mater Sci Eng 22 …

The nucleation and subsequent growth of helium bubbles in bulk tungsten is investigated
using molecular dynamics simulations. By considering a setting that includes the diffusion …

We investigate helium flux effects on helium transport and surface evolution in plasma-
facing tungsten using molecular dynamics. The simulations span two orders of magnitude …

Molecular dynamics simulations were performed to calculate the stress field in a tungsten
matrix containing a nano-scale helium bubble. A helium bubble in tungsten is found to …

Molecular dynamics simulations have been used to systematically study the pressure
evolution and bursting behavior of sub-surface helium bubbles and the resulting tungsten …

This work, with an emphasis on helium irradiation rates appropriate for fusion-plasma
conditions, advances the understanding of helium evolution at grain boundaries in W, an …

Nanometer-sized bubbles in tungsten containing various concentrations of helium and/or
hydrogen gas were studied using molecular dynamics simulations. Bubbles of different sizes …

The low solubility of hydrogen in tungsten leads to the growth of near-surface hydrogen
precipitates during high-flux plasma exposure, strongly affecting migration and trapping in …

A multiscale model of helium bubble evolution in plasma-facing materials is developed. The
model links different stages of helium bubble evolution: deposition, nucleation, growth …
