Abstract
|
|
|---|---|
| Tungsten is proposed as first wall material in future fusion reactors due to its good refractory properties, low activation rate and low tritium retention ? However, helium implantation inside vacancy-like defects leads to formation of bubbles filled with He atoms that will produce stress in tungsten ? Experimental results show that pulsed He irradiation (with fluxes up to 1013 cm-2 s-1) leads to these detrimental effects (pore formation and protrusions) at fluences as low as 1015 He cm-2 [1] ? A multiscale approach is used to describe the effects of He irradiation in tungsten | |
