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 …

In response to the nuclear industry desire to extend burnup beyond current licensing
practices, the US Nuclear Regulatory Commission (NRC) released a research information …

Helium plasma irradiation to various metals leads to peculiar morphology changes as
forming fiberform nanostructures called fuzz when a certain set of conditions is satisfied. In …

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 …

We report results of systematic molecular-dynamics computations of the elastic properties of
single-crystalline tungsten containing structural defects, voids and overpressurized He …

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) …

Tungsten (W) has become the most promising plasma-facing material (PFM) in fusion
reactor, and W still faces performance degradation caused by low-temperature brittleness …

Ductile-phase toughened tungsten (DPT W) composites have demonstrated a great
potential for plasma-facing components in fusion power systems. These materials can retain …

We describe model predictions of the temperature dependence for the formation of fuzz, a
nanofiber-like surface feature, on helium-plasma-irradiated tungsten surfaces under …

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 …
