Fusion fuels
Last week I posted about Greenpeace getting upset, for no reason, about Iter. They seemed to be worried that the high energy neutrons produced by fusion reactors of similar design to Iter could be used in the enrichment of nucleur weapons. This is despite this very avenue being researched by the military in the 1950's and then rejected as not cost effective.
Anyway Deutrium Tritium fuel is not the only one possible. It is just the only one with a low enough activation energy to be useful in Iter. There are many other reactions that could produce energy, including many that do not produce any neutrons at all. It's just that most of the aneutronic reactions require so much energy to get going that they are not within the range of what a Tokomac like Iter can use.
