Yeah I was really just talking about Nuclear Reactors as they are now. I know Thorium improves so many things.
Actually the worst of it is the non-fuel waste. But that's a tiny percentage of the total production.
The spent fuel rods themselves are only mildly VERY radioactive. This is why they'll be radioactive for thousands of years.
You could, once it's thermally cooled off, hold a spent rod in your gloved hand with no ill effect.
The reason they're sealed in casks is actual CHEMICAL contamination.
There ARE other technologies out there (Liquid Fuel Thorium) that work on a different nuclear cycle. And most of the fuel waste they produce is REALLY radioactive, but VERY short-lived.
Also, by design, the reactor has a default state of "off". If you somehow get an uncontrolled reaction, lose power, whatever, the supercooled plug to the reactor vessel melts and boom. The fuel drains into a dump tank and away from the reaction mass. Fission stops.
And unlike solid fuel reactors, you keep "cooking" the fuel and leeching off the byproducts.
Also, when it comes time to decommission a reactor vessel, you disconnect it and pull the entire vessel out of a concrete pit. You could, conceivably, drop a new reactor vessel into place, hook it up and continue pumping out power.
