Note that there are some fusion designs that do not result in radioactive waste. They're not the easiest to build though, so are unlikely to be what we use for first or second generation plants. For example, neutrons hitting lithium shielding produce tritium and helium, which can be fed back into the fusion reaction as fuel.
