I think the title explains it, but I am interested in how a world might differ from our own if fission had no radioactivity associated with the fuel, process, or waste/byproducts. The obvious answers are more nuclear power and maybe more common use of nuclear weapons, but I'm looking for other unexpected outcomes or unexpected secondary effects of the outcomes I mentioned.
If you've gotten this far without your head exploding: I understand how this sounds ridiculous, as radioactivity is a natural consequence of fission reactions. Try to focus on the outcome here, instead of the mechanism. If you just can't help it and feel the need to school me on why this is a spectacularly dumb question, go for it. Just make sure I learn something about nuclear physics along the way.
