Maybe you should talk to some actual nuclear engineers and not just read starry eyed proposals. The engineering tasks of building and maintainig said reactors plus digging up the waste and shipping it there is tremendous. Especially sodium cooled proposals get the most face palms from people who actually work in the field. "There's a reason psysicists don't design reactors but engineers do" is a quote I remember from the last time I met a nuclear engineer and discussed transmutation proposals.

Bottom line: Nothing is solved and it will take decades to get to a design that consumes new waste, let alone old waste that is currently rotting under ground and is ever harder to get to.
