nice disengenous quote used out of context, used nuclear fuel is a subset of waste from a nuclear power plant.

What's disingenuous about it? I guess there's used concrete that needs to be cleaned up, but used concrete is hardly unique to nuclear plants.
Also, your link about plutonium overdoses seems like a non-sequitur. Most spent fuel is uranium, not plutonium. Furthermore, chances of it contaminating people when that waste is buried 400 meters underground beneath impermeable rock is zero. The only things that would make it get into the ecosystem is deliberate excavation, or maybe a meteor strike kicking.
Low level rad waste still has cumulative health exposure risks, subject to many requirements for proper handling and disposal. there are lots of materials "not unique to nuclear plants" which do become irradiated once used in a nuclear plant.
BTW in hanford washington each year 10% of the DoE's budget goes to preventing plutonium leaking into a river, a lot of hubris to trivialize the geoengineering involved in designing a "zero risk" containment
