Multiscale modelling of diffusion and retention of hydrogen in multi-occupancy traps in irradiated bcc metals
Daniel Mason, Sanjeet Kaur, Samanyu Tirumala +3
We use molecular dynamics simulations to directly compute the effective diffusivity of hydrogen gas atoms in homogeneous distributions of monovacancies in tungsten and vanadium, an…

The effect of multi-occupancy traps on the diffusion and retention of multiple hydrogen isotopes in irradiated tungsten and vanadium
Sanjeet Kaur, Daniel R. Mason, Prashanth Srinivasan +5
We propose a computational scheme for the diffusion and retention of multiple hydrogen isotopes (HI) with multi-occupancy traps parameterized by first principles calculations. We s…

An empirical potential to simulate helium and hydrogen in highly irradiated tungsten
Samanyu Tirumala, Daniel R. Mason, Oliver Shattock +3
Materials used in commercial D-T fusion reactors will be exposed to irradiation and a mixture of helium and hydrogen plasma. Modeling the microstructural evolution of such material…
