Tungsten (W) is considered to be one of the most promising plasma-facing materials (PFMs)
for next-step fusion energy systems. However, as a PFM, W will be subjected to extremely …

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 …

We reveal the microscopic vacancy trapping mechanism for H bubble formation in W based
on first-principles calculations of the energetics of H-vacancy interaction and the kinetics of …

Understanding the interaction between atomic hydrogen and solid tungsten is important for
the development of fusion reactors in which proposed tungsten walls would be bombarded …

We have investigated the dissolution, segregation and diffusion of hydrogen (H) in a
tungsten (W) grain boundary (GB) using a first-principles method in order to understand the …

First principle calculations were used to study the hydrogen migration properties in bulk bcc
tungsten. Hydrogen has low solubility in tungsten and occupies the tetrahedral interstitial …

We investigate the physical origin of H–He interaction in W in terms of optimal charge
density by calculating the energetics and diffusion properties using a first-principles method …

The growth process of He bubbles in W is investigated using molecular dynamics and
parallel replica dynamics for growth rates spanning 6 orders of magnitude. Fast and slow …

The effect of hydrogen and helium interaction, especially H–He ratio, on the irradiation
behavior of nuclear materials has not yet been resolved. However, this is an important basis …

The configuration of multiple hydrogen atoms trapped in a tungsten monovacancy is
investigated using first-principles calculations. Unlike previous computational studies, which …
