Yeah and with a breeder fission reactor we could reduce this to below 1% probably. With a thorium breeder the fuel cost might be essentially 0%. In the vision of Alvin Weinberg you literally just drop some thorium into the fuel salt every once in a while.
But the real issue for nuclear energy is currently capital cost and time not fuel cost. And capital cost can go down massively with GenIV reactors as well.
So I don't see how fusion will be cheaper.
> In fusion it could be lower
But eventually you have to start breeding tritium, so wouldn't that make it more expensive.

Awesome, we desperately need GenIV reactors (even if I dislike that term).
