France’s nuclear fleet gives it one of the world’s lowest-carbon electricity grids

Would you like to source that? ALL of the High Level nuclear Waste from the planet can be fit into a 21m cube

Medium level waste and low level waste can be deposited in normal surface landfills. LLW is normaly considered non radioactive in 50 years MLW 200. Fun fact there are entire cities that are more naturally radioactive than what we consider MLW. https://pmc.ncbi.nlm.nih.gov/articles/PMC6709356/
I'd like to make an edit here later on and specify the reason that we do not put it into a 21 m cube is because it would go super critical.
