That implies that some countries have (figured out what to do with the solid nuclear waste)A lot of countries are just storing nuclear waste in above-ground water tanks. Not a long-term solution.
- Some countries have been dumping nuclear waste in the oceans, but that is now forbidden by international treaties.
- France planned to reprocess fuel, and feed the plutonium into fast breeder reactors. However, fast breeder reactors have proven very difficult to operate reliably
- A lot of countries are talking about long-term nuclear waste disposal, but none have an operating solution, as far as I can see...
At least the volume of radioactive waste is a lot lower than if you tried to capture carbon dioxide by reacting it with Magnesium...
- but radioactive waste is also a lot more dangerous than magnesium oxide...
- magnesium metal does not occur in nature, so you have to refine it from ores like magnesium oxide. And how do you do this without producing a lot of CO2?
