    After a long shutdown JET is back up and running at Culham with its new beryllium wall and tungsten divertor



    Thanks for the update. What is your role in this?

    Thanks also for the recipe suggestion. More for the food corner 🙂


    Regarding the beryllium – unfortunately it wont be a solution for a widespread application, at least for an ITER-like plant with beryllium blankets. Check this out: http://dx.doi.org/10.1016/j.fusengdes.2010.11.040

    I cite just the relevant paragraphs here. The rest is mostly about lithium anyway.

    “The situation with regard to beryllium and lead should also be
    discussed. Beryllium is regarded as a very rare metal. Despite its
    presence in over 90 known minerals, only bertrandite and beryl
    occur in minable concentrations. Annual production was 140 t
    in 2009; figures for the total reserves are not available, but the
    resources amount to only 80,000 t [18]!
    The beryllium burn-up in 2760 HCPB power plants would be
    524 t annually and the initial loading 331,000 t, vastly exceeding
    the present estimation of resources (see above)! The situation for
    lead in HCLL power plants is somewhat better: the annual burn-
    up would be 8560 t and the initial loading 11.3 Mt. With 1.5 Gt
    resources (see above) the burn up is such that there would be suffi-
    cient lead for about 175,000 years, assuming it were available only
    for fusion. This situation is far from optimal, but better than for
