I can't remember off hand, but I think you're right. Its something to do with the lithium neutron-catching outerlininh being turned into poisonous Beryllium. Some Freeper no doubt can chime in here.

Anyway: good luck to the Chinese if they can get this working.

I believe that early studies indicated serious waste disposal problems due to neutron activation of structural components. The containment structure had limited life (naturally) and would become so radioactive that it had to be built on crawlers so that it could "crawl" it way to an underground burial site.

Nice experiments for understanding high temperature fusion and the physics of stars but questionable as a viable power source.
