More invested in nuclear fusion in last 12 months than past decade

Only if we never use fast reactors, which fission almost all the long-lived stuff. Take what's left, encase it in glass and bury it, and it'll be back to the radioactivity of the original ore in 300 years.

Well, except for the 7 long lived fission products. Those are possibly good targets for space disposal.

You can separate them out and transmute them in fast reactors as well.

I suspect space disposal would be much cheaper.

Sure, the overall mix goes back to the radioactivity of the original ore, not a radioactivity of zero.
