You think.. I heard some antinuclear guys opposing fusion because the vessel for fusion reactor would get radioactive, and that is "nuclear waste" (of course, it's not the dangerous, long-term kind).
The neutron radiation around a fusion reactor is far more intense than in any fission reactor, because in fusion reactors most of the produced energy is carried by neutrons.
Any material exposed to neutron radiation will become radioactive. Of course the designers of fusion reactors will attempt to choose only materials that are converted into radioactive isotopes with a short halflife, but until someone demonstrates a working fusion reactor we will not know whether this is possible or the production of some amount of long-life radioactive waste must be accepted.
In my opinion, during the next few decades there are far less chances for fusion reactors to be used as a significant energy source on Earth than for some improved kinds of fission reactors.
In any case neither fission reactors nor fusion reactors are strictly necessary on Earth, but nuclear reactors are the only way to achieve interplanetary travel through the Solar System in decent times, so I believe that the future of nuclear reactors is for spaceships, not for terrestrial use.
I've commented before on this, but I don't think it ever becomes financially viable.
Assuming all the physics are completely solved tomorrow;
Private capital can easily get better returns, not to mention sooner returns, doing pretty much anything else.
Public capital requires a very long-term govt spend spanning multiple governments. China could do it, but hard to see a western govt doing it. Plus it would add a decade to the schedule and costs would spiral upwards.
All of which is a huge bet against improvements in grid-level storage.

For now this is only a desire, not a fact.
