In 1959 the Journal of Nuclear Materials (JNM) was founded and is now celebrating its
Diamond Anniversary year. The present paper is part of a series in which single JNM …

Tungsten, the primary material under consideration as the divertor material in magnetic-
confinement nuclear fusion reactors, has been known for the last decade to form'fuzz'—a …

Under the anticipated operating conditions for demonstration magnetic fusion reactors
beyond ITER, structural and plasma-facing materials will be exposed to unprecedented …

Large-scale molecular dynamics simulations of post-implantation helium behavior in plasma-
facing tungsten single crystals reveal orientation-dependent depth profiles, surface evolution …

Surface and near-surface morphology evolution of helium-irradiated tungsten due to thermal
cycling up to the ITER-relevant temperature of 1350 K was studied using electron …

Molecular dynamics (MD) simulations are performed to derive an equation of state (EOS) for
helium (He) bubbles in tungsten (W) and to study the growth of He bubbles under a W (100) …

The change in surface damage/microstructures and its effects on the hydrogen (H)
isotope/helium (He) dynamic behavior are the key factors for investigating issues of tungsten …

We present a comparison between a continuum-scale drift-diffusion-reaction cluster
dynamics prediction of helium retention in low-energy helium plasma exposed tungsten and …

Tungsten is a promising plasma facing material for fusion reactors. Despite many favorable
properties, helium ions incoming from the plasma are known to dramatically affect the …

Fission gas release within uranium dioxide nuclear fuel occurs as gas atoms diffuse through
grains and arrive at grain boundary (GB) bubbles; these GB bubbles grow and interconnect …
