Aneutronic fusion is possible, but requires collision energies much higher than what ITER is designed to create.
- Symmetry 7y agoIn theory you can chose construction materials that don't do anything too horrible when you bang them with neutrons in the construction of your fusion reactor. I'm not sure how well this is achievable in practice in the construction of a fusion reactor but I'm pretty sure they can avoid using anything that creates byproducts as nasty as uranium does. EDIT: I do wonder if there's a danger of nuclear proliferation with using fusion reactors to breed plutonium from natural uranium, though.
