There's a lot of energy in those 112 tonnes, but you really need a fast reactor to burn it. Plutonium is a lot easier to tackle in a fast reactor than a thermal reactor.

Also, UPower can use the waste without putting it through a chemical separations process. In fact you can just take the SNF grind it up, and dump it into the UPower reactor alongside the rest of the fuel. It actually makes a pretty good fuel that way.
