People say that fusion will use very cheap and harmless fuel to generate energy. But practically the real fuel will be all the replacement parts that will be constantly degraded and used up to maintain it's operation.
That's true if of any power plant though. It'll still be cheaper and safer (if it ever works).
I was under impression that for tokomak fusion the enclosure have to be so precisely manufactured that any minor damage requires replacement. If so, then maintenance will be way more expensive than regular power plants.
