All this applies to fission as well. By today, we could have had intrinsically safe fission reactors in place and working (we do have intrinsically safe reactor DESIGNS, but they have not been commercialized).
And don't give up on fusion quite yet. There are versions of both hot AND "cold" fusion that are much closer to realization than you might think (although I think you are correct on the "magnetically confined" versions).
The hot fusion design can be found with search terms {"bussard polywell"}....without the curly brackets, of course.
The cold fusion design can be found with search terms {Rossi "cold fusion"}...again without the curly brackets.
I'm using search terms rather than links so you can see both the positive and negative points from various people, rather than providing a direct link to each so as not to "pre-prejudice" what you might see.
