D + T → He + n

Imagine a world in which there are no energy crises, no fossil fuel power stations to churn out carbon dioxide to contribute to global warming, no radioactive waste or pollution problems, no wind turbines in your back yard or scarring the skyline, no tidal barrages to upset the estuarial ecologies. No, that's not a pre-industrial world you are picturing; it's the world of the future when nuclear fusion, not nuclear fission, will be the shape of nuclear energy. Unlimited, unpolluting, and unmilitarisable - that's the sort of nuclear energy I support. It's a dream, but not a pipe-dream. I doubt if my generation will see this world, but it's one that I would want my grandchildren to see.

Neutrons do just disappear. They have a half-life of about 10 minutes, decaying into protons. It's what they might do before that which could produce radioactive waste in any surrounding containment vessel. This is not yet determined because of the early stages of research, but the quantity of waste is likely to be orders of magnitude less than that produced in fission reactors.
