I'm a bit at a lost, can you elaborate on how fusion would produce more radioactive waste than fission? We already have a few fusion generators designs so is not a sweeping statement on something totally unknown. AFAIK, the by-product of fusing Tritium/Hydrogen is Helium, which is far from radioactive. I might imagine that some radioactive isotopes might get produced as well, but I can't imagine it being nowhere near as dangerous as spent uranium fuel and contaminated components in fission reactors.

In a case of an accident I would also imagine an explosion from a Fusion Reactor, but the fallout of it would not even close as dramatic as a Fission Reactor leak or explosion
