It may be slightly different that other forms of energy, because a large part of nuclear’s cost is regulatory compliance and political buy-in.
We know how to design safe nuclear reactors. We just can't build them cost-effectively, because there is always some subsubsubsubcontractor that doesn't bother doing things by the book. Then an inspector notices that something is wrong and orders it dismantled and rebuilt. And this will be iterated until everyone manages to do the right thing at the same time.
It’s a space where you can’t cut corners.
