> A typical large reactor produces 25-30 tonnes of used fuel per year.

Falcon 9 carries that to Low Earth Orbit. You do not want the waste hanging around there. To get it out of earth's orbit, F9 can do 8 tons.

That's 3 - 4 flights per year per reactor, so about $250m per year. Plus Falcon 9 did 60 flights this year, so this even capacity-wise this would only be enough for 20 reactors worldwide.

Plus like other commenters mentioned, a launch failure would be catastrophic.
