Well, I certainly didn't think we could just pour it right back in the reactor.
To say the least, the stuff corrodes the barrels in which it is stored, and most corrosive reactions involve electron exchange, from which we should be able to derive a current, and those are specially made barrels: I'm sure we could come up with something more easily corroded. Of course, for all I know the corrosion is a result of neutron activity, rather than electron exchange. Sadly, I am not a nuclear physicist.
I don't know all relevant details of alpha, beta, or gamma particles, or loose neutrons, but I know that some of those can be converted to light, which could be converted to electricity.
I suppose the electricity obtained in these ways probably sells for less than the cost of developing or producing whatever equipment might be required.
I just hate to see people complain about unharnessed radiation
