But where do you store the used uranium later on I mean we have seen in Germany what happened, no one wanted to have such a final storage facility.
94-97% of nuclear waste is recyclable. (See :Orango La Hague) The leftover waste you vitrify. Stable, vastly shorter half life.
Send the waste to space and let it float
Definitely. We have the tech. Designate some distant moon. Or burn it up in the sun? Recycle and reuse the 97%. Vitrify and launch the remaining 3% waste.
