So the Independent article above mentions a Tokamak reactor, I thought it might be interesting to see if they use Tungsten and any more info, found this article: https://www.iter.org/newsline/-/3951#:~:text=In%20its%202016%20baseline%20configuration,and%20particle%20exhaust%20will%20be
In which they say: "...tungsten is a remarkable material in terms of robustness and has the highest melting point (3422 °C) of all known elements, an elevated energy threshold for sputtering, and negligible fuel retention issues in comparison with beryllium. These are the principal reasons for deploying it in the divertor region, where steady heat and particle fluxes are extremely high. It does, though, have one serious drawback: as a very high atomic number material, only very small concentrations will be tolerable in ITER's fusion plasmas before the burn is compromised. Nevertheless, tungsten is the most widely favoured candidate in most magnetic confinement fusion reactor designs, and the long-term objective of ITER has always been to operate eventually with tungsten as sole plasma-facing material after starting first nuclear operations with beryllium main wall armour to ease the pathway to burning plasmas. In view of technical issues which have arisen during machine construction, this long-term plan is now being brought forward in a new proposal currently under development at the ITER Organization to go "full-tungsten" from the very beginning of operations. A review of this proposal was the sole objective of last month's STAC meeting (ITER Council Science and Technology Advisory Committee) held at ITER Headquarters."
The article, backing up everything OF has been saying, is quite bullish for the future use of Tungsten.
